Abstract. Glemparon Jaschhof, 2013, a previously monotypic genus conned to Sweden, is shown here
to be considerably richer in species, with most species found to occur in the Australasian region. Eighteen
new species are described: G. tomelilla sp. nov. (from Sweden); G. aotearoa sp. nov., G. birhojohmi
sp. nov., G. cervus sp. nov., G. didhami sp. nov, G. kaikoura sp. nov., G. nativitas sp. nov., G. orautahi
sp. nov., G. otago sp. nov., G. pureora sp. nov., G. rakiura sp. nov., G. rotoiti sp. nov., G. rotoroa sp. nov.,
G. tewaipounamu sp. nov., G. waipapa sp. nov., G. waipoua sp. nov. (all from New Zealand); G. manuka
sp. nov. and G. warra sp. nov. (both from Tasmania, Australia). Glemparon sagittifer Jaschhof, 2013 is
redescribed. Genitalic illustrations are provided allowing for the effective identication of all the species
known thus far. Morphological data obtained here are used for revising the generic denition. Dicerura
Kieffer, 1898 is hypothesized as the sister group to Glemparon. The case of Glemparon is discussed as a
perfect example of the fact that our collective ignorance of porricondyline diversity in most parts of the
world is a major impediment to a better understanding of the European species.

Introduction
The genus Glemparon Jaschhof, 2013 was introduced to absorb a single, unusual species of dicerurine
Porricondylinae, of which two males had been captured by The Swedish Malaise Trap Project in two
places in southern Sweden (Jaschhof & Jaschhof 2013). Morphological analysis revealed this species,
Glemparon sagittifer Jaschhof, 2013, to differ from all other Dicerurini by the presence of setae on both
the postfrons and the metepisternum. Other distinctions found concern genitalic structures: the ventral
gonocoxal emargination, which is provided with a complex, largely membranous outgrowth (revised
and called the posteromedial protuberance in the present paper) and the tegmen, which has two pairs
of processes (Jaschhof & Jaschhof 2013: g. 64A–B). As both specimens of G. sagittifer available

for description were lacking the antennal apices, the number of agellomeres (one of the standard
taxonomic characters in Porricondylinae) could not be determined. The afliation of G. sagittifer to
other Dicerurini could not be resolved, partly due to the many morphological peculiarities, partly due to
the fact that so much of the diversity of world Dicerurini remains undescribed, rendering it unavailable
for comparison. This unsatisfactory situation began to change with our recent discovery of an unnamed
congener of G. sagittifer in previously unstudied Malaise material from Sweden; again two males
from two sites in the south of the country. Closer study of the morphology of this species, named here
G. tomelilla sp. nov., revealed structures that reminded one of us (MJ) of similar-looking species he
had studied a few years ago, from New Zealand. Reinvestigation of these species, which until then
remained as unnamed Dicerurini of unresolved generic afliation, conrmed that they belong to the
genus Glemparon. In addition, two more unnamed species of Glemparon were identied among a few
Porricondylinae specimens we had at our disposal from Tasmania. All these new species, altogether
18, are described and named here, thereby documenting remarkable species richness in a previously
monotypic genus. New morphological data are used for revising the generic denition. Glemparon
is hypothesized to be the sister group to Dicerura Kieffer, 1898, a genus of 32 named species in the
Holarctic region (Jaschhof & Spungis 2018). The odd, disjunct distribution of Glemparon, now with two
Palearctic and 17 Australasian species, is discussed.
Material and methods
Of the two Swedish species of Glemparon, a total of four male specimens were obtained from The Swedish
Malaise Trap Project (SMTP; http://www.stationlinne.se/sv/forskning/the-swedish-malaise-trap-project-
smtp, accessed 8 Mar. 2018) and The Gall Midge Project (http://www.stationlinne.se/sv/forskning/the-gall-
midge-project, accessed 8 Mar. 2018). Specimens from New Zealand, altogether 19 males, come from
Malaise samples that we studied during our “Lestremiinae of New Zealand” project (2001–2003; see
Jaschhof & Jaschhof 2003). Two Glemparon males from Tasmania were picked from Malaise samples
provided by The Tasmanian Forest Insect Collection in the care of Forestry Tasmania, Hobart (see
Jaschhof & Jaschhof 2008). All in all, 24 specimens were studied and identied here as belonging to
19 different species. Our specimens from Sweden result from studying hundreds of Malaise samples
from all over Sweden for new or otherwise interesting Porricondylinae, while the specimens from New
Zealand and Tasmania were picked out merely for curiosity and should therefore be regarded as chance
by-products from gathering material of Lestremiinae and Micromyinae, our focal taxa at that time.

The procedures of specimen preparation and identication as well as the morphological terminology used
in adult Porricondylinae were recently described by Jaschhof & Jaschhof (2013). Several morphological
terms, some of which specic to Glemparon, are explained in Figs 2–3, 6 and 15 of the present paper. Body
length, measured on slide-mounted specimens, is given including the genitalia. The gonocoxites of male
Porricondylinae, including Glemparon, are merged into a single structure and thus described as a unit. Both
the cerci and hypoproct are not described (nor illustrated) here; they might have taxonomic merit, but, since
they tend to distort and be overlayed by other structures, are difcult to study. Arrows are used to highlight
important diagnostic characters in both the wording and illustrations of a taxonomic description, with numbers

referring to particular characters (↓1, ↓2, ↓3, etc.). Descriptive sections other than diagnoses, titled here “Other
characters”, make mention only of those characters not referred to before. Species are treated according to
geographical distribution (Sweden, New Zealand, Tasmania) and, within this scheme, in alphabetical order.
Most of the new species are named after geographic localities, with names used as nouns in apposition as to
retain their euphony. Exceptions to this practice are explained in the respective etymology sections.

Diagnosis
Glemparon is known only from males; females and larvae remain unrecognized. Unprecedented within
Dicerurini, the number of agellomeres varies among different species of Glemparon from 12 to 18, as
far as is known. Basitarsal spines are either present (Fig. 1A) or absent (Fig. 1B), which is another unusual
case of intrageneric variation. Genitalic structures show the following synapomorphous characters, with
four or more present in a single species: (1) the gonostylar apex is laterally compressed (Fig. 2B); (2) the
gonocoxites have a posteromedial protuberance, which is largely membranous (and thus hard to study
by light microscopy) and usually structured in complicated ways (Fig. 2A; see remarks below), and
(3) extensive membranous areas ventroposteriorly below the gonostyli (Figs 2A, 4A); (4) the tegmen
is provided with a pair of posterolateral processes that are mostly serrate or tubercular (Fig. 15C) and
(5) with a pair of elongate apodemes (Fig. 15C; called here the longitudinal apodemes, equal to the
ventral processes by Jaschhof & Jaschhof (2013: g. 64A); see remarks below); (6) the ejaculatory
apodeme is invariably single-pointed and mostly arrow-shaped (Fig. 3C); (7) the posterior edge of the
ninth tergite, which is convex (as opposed to concave or bilobed), is mostly provided with megatrichia
(Fig. 6D; see remarks below).
Other characters
As our present study reveals, G. sagittifer is the only species of Glemparon whose postfrons and
metepisternum are setose; in all the congeneric species those sclerites are devoid of setae. Therefore, the
presence of pronotal and metepisternal setae cannot be regarded as generic characters (see Jaschhof &
Jaschhof 2013). The agellomeral necks are shorter (Fig. 1H) to several times longer (Fig. 1F) than the
nodes. Circumla, which are present on all but the terminal agellomeres, have posterior extensions
only on the proximal agellomeres; those extensions, which have different lengths, are either closely
adpressed (Fig. 1F) or free-ended (Fig. 1G). In species with generally short extensions, some of the
circumla are simply ring-shaped or sinuous (Fig. 1H). The agellomeral nodes are completely covered
with microtrichia, while the necks are always glabrous. The palpus of G. sagittifer was described to have
only two to three segments (Jaschhof & Jaschhof 2013), whereas the conspecic specimen described
in the present paper has four segments. The four-segmented condition is found, invariably, in all other
species of Glemparon, but both the lengths and shapes of palpal segments are subject to variation, both
among different species (see Fig. 1C vs Fig. 1D) and within one and the same species (see Fig. 1D
vs Fig. 1E). Pronotal setae are either present or absent. The claws of Glemparon are subrectangular
rather than evenly bent, with the distal sections clearly longer than the basal sections, and with one large
and two to three small teeth basally.

Remarks on certain genitalic structures
The structure called here the posteromedial protuberance possibly indicates the presence of the ninth
sternite, which in the basal subfamilies of Cecidomyiidae, including Porricondylinae, is thought to
be merged, mostly untraceably, into the ventral gonocoxal bridge (see Jaschhof & Jaschhof 2013).
Protuberances similar to that found in Glemparon are also present here and there in other Dicerurini,
such as Dicerura complicata Spungis, 1987; D. adunca Borkent, 1990; and Linnaeomyia hortensis
Jaschhof & Jaschhof, 2015; but only in Glemparon do they have an elaborate structuring. As a matter of
fact, Porricondylinae show quite a variety of different modications at the base of the ventral gonocoxal
emargination, many of which might be derived from the ninth sternite; examples are the gonocoxal
processes of many Porricondylini (Jaschhof & Jaschhof 2013: g. 98B) and different kinds of abnormal
vestiture found throughout the subfamily (Jaschhof & Jaschhof 2013: g. 155A). In many Glemparon
the posteromedial protuberance appears to be connected to either the apex of the ejaculatory apodeme or

the tegmen, or both; however, their mostly membranous texture and small size makes these connections
difcult to study using light microscopy.
The longitudinal apodemes arising from the tegmina of many Glemparon are, to our knowledge, unique
within the Dicerurini. They arise, as far as one can discern, from the bases of the posterolateral processes,
and either end freely or connect to the inside of the gonocoxal wall. Due to the muscles attached to them,
these apodemes are quite conspicuous in our specimens, but one cannot be sure about their visibility in
macerated specimens where they possibly become eliminated together with the muscle tissue.
The integumental projections referred to here as megatrichia are conspicuously enlarged microtrichia,
which appear to be attened and bent apically. Megatrichia are unknown to us in other Porricondylinae,
including Dicerurini. In Glemparon, they are situated next to ordinary, hair-like microtrichia as well as
tubercle-like microtrichia (Fig. 14B), which, within Dicerurini, are found also on the ninth tergite of
several Dicerura (e.g., Jaschhof & Jaschhof 2013: g. 54A). In Porricondylinae, as in other fungivorous
Cecidomyiidae, the phenotypic variation of microtrichia is insufciently studied.
Relationships to other Dicerurini
Male morphology suggests that Glemparon is the sister group to Dicerura. In both genera the gonocoxites
are provided with ventroposterior lobes (referred to as gonocoxal processes by Jaschhof & Jaschhof
(2013)), which we interpret here as a synapomorphy. The same kind of gonocoxal lobes are present here
and there in other Dicerurini, but the few species concerned have genitalic structures that otherwise are
very different from that in Glemparon and Dicerura. While there is always a single pair of gonocoxal
lobes present in Glemparon, Dicerura may have either one or two pairs. Another derived trait shared
by the two genera is the presence of modied microtrichia on the ninth tergite. Apart from large, coarse
microtrichia the size of setulae that are commonly found in both genera, many Dicerura have coniform,
tubercle-shaped microtrichia, whereas many Glemparon have megatrichia. A third similarity in genitalic
characters is that the gonostyli of both groups have exposed, densely microtrichose areas, which in
Glemparon are situated at the gonostylar apex but in Dicerura at the gonostylar base (“mediobasal lobe”,
see Jaschhof & Jaschhof (2013)). Very few Glemparon have microtrichose bulges at the gonostylar
bases, but then in a dorsal, not medial, position. Despite the fact that areas of dense microtrichia are
exposed in different positions on the gonostylus – apical in Glemparon, basal to medial in Dicerura –
their presence might be another indicator of the common ancestry of both genera. Indicative here
are the short, blunt-ended bristles situated among the microtrichia in both Glemparon and Dicerura;
those bristles are typically located at or near the gonostylar apex (not only in Dicerurini and other
Porricondylinae but throughout the fungivorous subfamilies of Cecidomyiidae). It therefore stands to
reason that the mediobasal lobe found in Dicerura is actually the gonostylar apex. If so, Glemparon and
Dicerura concur in having exposed areas of dense microtrichia intermingled with a few short bristles at
the gonostylar apex. To end on another interesting note, two species of Dicerura with structures similar
to the gonocoxal posteromedial protuberance found in Glemparon, namely D. complicata and D. adunca,
are so aberrant also in other genitalic characters that one might doubt the validity of their current generic
placement. However, both species are characterized as true Dicerura by the possession of a bifurcate
ejaculatory apodeme, which is the character distinguishing Dicerura from all other Dicerurini, including
Glemparon.
Identication of species
Males of Glemparon can be identied to species using genitalic characters. Each of the 19 species
known to date is distinguished by a specic design of either the tegmen or the gonocoxites. Even so,
we usually refer to three different structures – usually gonocoxites, gonostylus and tegmen – when
diagnosing species, for there is every indication that similar-looking species of Glemparon exist that
might be found in the future. Illustrations can describe those structures best and scanning them is, in
European Journal of Taxonomy 450: 1–38 (2018)

our estimation, the most effective way to identify these taxa. For the same reason we refrain here from
presenting a key. The present study, though based on only one to three specimens per species, revealed
that non-genitalic characters tend to vary intraspecically, such as the number of agellomeres and the
outline of palpal segments. Consequently, such characters should be used with caution until the extent
of variation is better known.
Species of Glemparon in Sweden
Glemparon sagittifer Jaschhof, 2013
Fig. 2A–B
Since the rst description of this species (Jaschhof & Jaschhof 2013), only two additional specimens,
again males, have been found, one of which is gured here to show some of the genitalic structures
in better detail. The gonostylus of G. sagittifer is strongly compressed apically (Fig. 2B), the outline
typically found in Glemparon. The gonocoxal posteromedial protuberance possibly bears a pair of
dorsally directed processes, of which only the transverse sections are visible in ventral view (↓1, Fig. 2A).
One of our specimens has the antennae completely preserved, including 15 agellomeres. The palpus,
which is conspicuously short, has either three or four segments (not either two or three as previously
described); pronotal setae are absent (not mentioned in the original description); and the metepisternum
has one to three setae (not only one or two as previously described).

Figs 1D–E, H, 3A–D
Diagnosis
The ventroposterior edge of the gonocoxites has a V-shaped emargination anked by subtriangular
lobes of moderate size (↓1, Fig. 3A); the posteromedial protuberance has a slightly sinuous edge and
a pair of ovate substructures, whose outline may remind one of eyeglasses (↓2, Fig. 3A). The roughly
H-shaped tegmen is provided with a pair of posterolateral processes whose spike-bearing apices are bent
ventrolaterally (↓3, Fig. 3D). The vestiture of the ninth tergite (Fig. 3A) consists of normal setae and
microtrichia; megatrichia are absent.
Etymology
The specic epithet refers to Tomelilla, a small town in Sweden’s province Skåne, where the holotype
specimen was collected.

Differential diagnosis
Glemparon tomelilla sp. nov. differs from G. sagittifer, the only congener in the Palearctic, in the
outline of the posterior gonocoxal edge, the structuring of the tegmen, and the more slender gonostylus.
Furthermore, G. sagittifer has metepimeral setae, which are missing in G. tomelilla sp. nov. A species
with genitalic structures generally similar to that of G. tomelilla sp. nov. is G. warra sp. nov. from
Tasmania (Fig. 20A–D).

except the concave portions medially and the somewhat angular-shaped, densely microtrichose apex
(Fig. 3B). Ejaculatory apodeme with large, membranous, arrow-shaped apex (Fig. 3C).
Distribution and phenology
This species is known from two locations in southern Sweden, where only two specimens were
obtained as a result of extensive Malaise trapping all over Sweden by both the Swedish Malaise Trap
Project and ourselves for several years. A common feature of the two collecting sites is that grasses
predominate in the ground cover, with one of the sites being markedly dry, the other rather swampy.
Specimens were collected during the main vegetation period in May–August.

Fig. 4A–C
Diagnosis
A peculiarity of G. aotearoa sp. nov. is the markedly bulbous gonostylus (↓1, Fig. 4B). Of the
gonocoxites, the membranous areas below the gonostyli are conspicuously large (↓2, Fig. 4A), the small,
subrectangular, ventral emargination (↓3, Fig. 4A) is anked by subtriangular lobes of moderate size,
and the posteromedial protuberance is inconspicuous. The posterolateral processes of the tegmen have
serrate edges, including one larger, bent sawtooth anteriorly (↓4, Fig. 4C).
Etymology
The specic epithet, aotearoa, is the Maori name for the country of New Zealand, meaning “land of the
long white cloud”.

Distribution and phenology
The single specimen known of G. aotearoa sp. nov. was Malaise trapped at the height of summer
in an old-growth native forest in the north of New Zealand’s South Island. The same trap collected
simultaneously four other species of Glemparon: G. birhojohmi sp. nov., G. cervus sp. nov., G. rotoroa
sp. nov., and G. tewaipounamu sp. nov.

Fig. 5A–C
Diagnosis
The following combination of genitalic characters is characteristic of G. birhojohmi sp. nov.: the
gonostylus, which is twice longer than broad, is slightly constricted subbasally (↓1, Fig. 5A); the
gonocoxal posteromedial protuberance, which is anked by small, subtriangular lobes, has a weakly
sclerotized, T-shaped process that projects ventrally (↓2, Fig. 5A); below the protuberance is an
assemblage of conspicuously dense setae (↓3, Fig. 5A); and the medial bridges have mostly setae of
various sizes rather than microtrichia.
Etymology
In naming this new species birhojohmi, we honor Birgit Rhode and John Mitchell, of Papakura,
Auckland, New Zealand. Birgit and John, both gifted with an artistic, creative disposition, have
been supportive of our taxonomic work for many years. The name should be treated as a noun in
apposition.

TerminaLia. Posterior edge of ninth tergite with dense megatrichia. Gonocoxites without setae on
narrowed ventrobasal portion (Fig. 5A). Gonostylar apex with slight depression above densely
microtrichose portion medially (Fig. 5A). Sclerotized portion of ejaculatory apodeme pointed apically,
covered by membranous cap (Fig. 5C). Posterolateral processes of tegmen with serrate edges, including
1–2 larger sawteeth anteriorly (Fig. 5B–C; see remark on variation).
Remark on variation
The paratype (Fig. 5B) differs slightly from the holotype (Fig. 5C) in that the tooth situated most anteriorly
on the tegminal processes is conspicuously large and bent. These teeth are apparently somewhat variable
in shape, size, and relative position.
Distribution and phenology
See G. aotearoa sp. nov. The paratype of G. birhojohmi sp. nov. was captured almost three months later
than the holotype at the same site, indicating a long adult ight period in this species.
Glemparon cervus sp. nov.
urn:lsid:zoobank.org:act:B186CEF1-8C4B-4FBF-98A3-C3A07A7EFC41
Fig. 6A–D
Diagnosis
The elongate gonostylus is markedly wedge-shaped all along the medial edge (Fig. 6B). The gonocoxites
have conspicuously large membranous areas below the gonostyli (↓1, Fig. 6A); the posteromedial
protuberance is provided with a pointed, sclerotized process that projects ventrally (↓2, Fig. 6A). The
tegminal processes, with their multiple points, are reminiscent of deers’ antlers (↓3, Fig. 6C).
Etymology
The specic epithet, cervus, is the Latin word for deer, an allusion to the antler-shaped tegminal processes
found in this species. The name is a noun in apposition.

Differential diagnosis
A remarkably similar species found co-occurring with G. cervus sp. nov. is G. tewaipounamu sp. nov. It
differs in both the gonostylus, which has a pubescent bulge dorsobasally (Fig. 16B), and several details
in the gonocoxites (Fig. 16A) and the tegmen (Fig. 16C). The posteromedial protuberance provided with

Diagnosis
The gonostylar base in G. nativitas sp. nov. is broader than in any other species of Glemparon (↓1,
Fig. 9B). The setae on the ventral gonocoxal surface form a cross-shape (Fig. 9A); the medial bridges
are densely microtrichose (↓2, Fig. 9A); and the posteromedial protuberance has a T-shaped, sclerotized
process that projects ventrally (↓3, Fig. 9A). The tegminal processes have a serrate posterior edge, with
the largest sawteeth situated ventrally (↓4, Fig. 9C).

Glemparon otago sp. nov.
urn:lsid:zoobank.org:act:A10DF0E4-2C9C-45C9-B85C-79AC1296AE3F
Fig. 11
Diagnosis
The genitalia of this species (Fig. 11) differ from what is typically found in Glemparon. In particular, while
the gonostylus is narrowed apically, it is not laterally compressed; the gonocoxites lack membranous
areas below the gonostyli; and the apex of the ejaculatory apodeme is not arrow-shaped. An absolutely
distinguishing structure is the tegmen, which ends in a pair of sclerotized points (↓1, Fig. 11) and has a
pair of lateral processes each consisting of about 10 tubercles (↓2, Fig. 11).
Etymology
The specic epithet, otago, is of Maori origin and refers to the Otago Region in the south of New
Zealand’s South Island, where the holotype was collected.

TerminaLia (Fig. 11). Posterior edge of ninth tergite broadly rounded, with normal microtrichia.
Gonocoxites with large unsetose portion ventrobasally; ventroposterior lobes small, rounded; ventral
emargination shallow; posteromedial protuberance indistinct, apparently completely membranous (not
depicted in Fig. 11); dorsal apodemes shorter and thicker compared with other Glemparon. Gonostylus
strongly bent on apical third, with densely microtrichose protuberance dorso-subapically. Ejaculatory
apodeme progressively membranous basally, with sclerotized broadening apically.
Discussion
Our reasons to classify this species in the genus Glemparon are the possession of 17 agellomeres,
i.e., more than the 14 agellomeres usually found in Dicerurini, and the presence of ve out of eight
genitalic characters regarded as synapomorphous in Glemparon (see the generic diagnosis above).
There is no better, alternative generic placement for G. otago sp. nov. The somewhat aberrant genitalic
morphology of this species gives an idea of the diversity of structure met in Glemparon, a fact to bear in
mind as other unusual, hard-to-place Dicerurini will be found in the future. Glemparon rotoiti sp. nov.,
which is described below, possibly lies between G. otago sp. nov. and other, more typical species of
Glemparon.
Distribution and phenology
The holotype of G. otago sp. nov. was collected in summer in the high mountains of New Zealand’s
Southern Alps, in a patch of native bush according to the specimen label.

urn:lsid:zoobank.org:act:0D7479C0-70CB-4C3F-BF70-DF9D924895CC
Fig. 12A–B
Diagnosis
Glemparon pureora sp. nov. is distinguished from congeneric species by the compact gonostylus, which
is strongly tapered towards the apex (↓1, Fig. 12A); the broadly V-shaped gonocoxal emargination
(Fig. 12A); the posteromedial protuberance, which has a three-branched sclerotization, with the medial
branch forming a ventrally directed process (↓2, Fig. 12A); and the tegmen, which ends in a pair of
serrate processes that point ventrolaterally, and whose posterolateral processes are three-pointed (↓3,
Fig. 12B).
Etymology
The specic epithet, pureora, refers to the type locality of this species, Pureora Forest Park in the North
Island of New Zealand, which protects one of the earth’s nest podocarp forests.

Diagnosis
Glemparon rakiura sp. nov. is distinguished by the gonocoxal ventroposterior lobes, which
are conspicuous by their globular shape and dense cover with thick, spine-like microtrichia
dorsomedially (↓1, Fig. 13A). The gonostylus, which basically is rather slender, has a densely
microtrichose protuberance dorsobasally (↓2, Fig. 13A). The ninth tergite has a narrow posterior
portion, which is separated from the much broader anterior portion by a constriction and is covered
with microtrichia of various sizes; the posterior edge is provided with about 10 megatrichia (↓3,
Fig. 13B).
Etymology
The specic epithet, rakiura, is the Maori name for Stewart Island, the provenance of the holotype
specimen.

Diagnosis
The elongate gonostylus of simple shape is not compressed at the apex, which is rounded and covered
with dense microtrichia (↓1, Fig. 14A). The gonocoxites are peculiar for both the membranous portions
ventroposteriorly, whose outline resembles a stair (↓2, Fig. 14A), and the ventral emargination, which
is large, somewhat rectangular and vaguely delineated at the base (↓3, Fig. 14A). The ninth tergite
has an almost truncate, strongly sclerotized posterior edge (↓4, Fig. 14B), which is a unique feature in
Glemparon, and on the inside numerous small tubercles in indistinct rows. The tegmen is provided with
a pair of sclerotized, serrate points (↓5, Fig. 14C) and, at the points’ bases, sclerotized processes each
consisting of two curved teeth (↓6, Fig. 14C).

Fig. 16A–C
Diagnosis
A combination of genitalic characters is characteristic of G. tewaipounamu sp. nov., as follows. The
elongate, slightly bent gonostylus has a densely microtrichose bulge dorsobasally (↓1, Fig. 16B). Of
JASCHHOF M. & JASCHHOF C., New Glemparon from Sweden and the southwest Pacic

the gonocoxites, the posteromedial protuberance is largely unmodied except for inconspicuous folds,
which indicate some kind of structuring (↓2, Fig. 16A); and the medial bridges have a section with
large, dense microtrichia (↓3, Fig. 16A). The posterolateral processes of the tegmen, which are strongly
sclerotized, are a complicated assemblage of teeth, tubercles and serrate ridges (↓4, Fig. 16C).
Etymology
The name of this species, tewaipounamu, is the original Maori name for the South Island of New
Zealand, where the holotype was collected.

Diagnosis
This is another absolutely distinctive species. No Glemparon other than G. waipapa sp. nov. has an
ejaculatory apodeme with such a sclerotized, lance-shaped apex (↓1, Fig. 17B) and tegminal processes
shaped like wine grapes (↓2, Fig. 17B). Another diagnostic feature is the large, sclerotized process arising
from the gonocoxal posteromedial protuberance (↓3, Fig. 17A).

urn:lsid:zoobank.org:act:8C07CF84-F7E3-4506-B538-C69C1F43B4E5
Fig. 18A–C, E
Diagnosis
A combination of genitalic characters is diagnostic of G. waipoua sp. nov., as follows. The elongate
gonostylus is peculiar for its pointed apex (↓1, Fig. 18A); the ventral emargination of the gonocoxites, which
is small, has a microtrichose bulge and no setae basally (↓2, Fig. 18C); and the tegmen has two transverse
struts (↓3, Fig. 18E) as well as posterolateral processes each with 8–9 sclerotized teeth (↓4, Fig. 18E).
Etymology
The specic epithet, waipoua, refers to Waipoua Forest, a sanctuary for the nest kauri forest preserved
in New Zealand, which is the type locality of this new species.

TerminaLia. Posterior edge of ninth tergite with about 20 megatrichia medially anked by inconspicuous
microtrichose lobes (Fig. 18B). Gonocoxites with narrow, unsetose portion ventrobasally; ventral setae
reduced to a transversal stripe in center; membranous areas below gonostyli large; ventroposterior lobes
small, rounded; posteromedial protuberance unmodied except for a distinct longitudinal fold; medial
bridges with short, densely microtrichose sections (Fig. 18C). Gonostylus more than 3.0 times longer
than broad (Fig. 18A). Ejaculatory apodeme with elongate, membranous apex (Fig. 18E).
Distribution and phenology
This species, known only from the holotype, was collected in the subtropical winter of New Zealand’s
Northland, in a forest predominated by kauri trees.
Notes on a possibly closely related, unnamed species
Among the Glemparon studied here is a male (NZAC, no. CEC1413) from the Westland Region in
New Zealand’s South Island, which largely ts the description of G. waipoua sp. nov. given above, with
the exception of the genitalic structures that resemble those shown in Figure 18D. In this specimen,
the gonocoxal ventroposterior lobes are smaller; the ventral emargination has a sclerotized basal edge
(no microtrichose bulge as found in G. waipoua sp. nov.); and, most importantly, the tooth-bearing
processes of the tegmen protrude beyond the gonocoxal wall, which is something we have noted in
no other Glemparon. We refrain from describing this specimen as a new species, because it resembles
G. waipoua sp. nov. in all other respects and we cannot be absolutely sure whether the peculiarities
observed are just due to preparation artifacts.

Figs 1A, F, 19A–B
Diagnosis
The complex genitalic structures found in G. manuka sp. nov. make this the most unusual species we
have seen of Glemparon. The tegmen and ejaculatory apodeme form a structural unit, which is also
linked to the gonocoxal ventral wall; for simplicity we refer to this entire structure as the tegmen. The
abundance of serrate and tooth-bearing lobes on the tegmen, which is unique, is shown in Figure 19A.
The gonocoxal posteromedial protuberance is missing as a distinct structure, but we suppose it is merged
into the tegmen.

Etymology
The specic epithet, manuka, refers to the Manuka Road in the Warra Long Term Ecological Research
site, Tasmania, where the holotype specimen of this species was collected. Manuka (Leptospermum
scoparium J.R. Forst. & G. Forst.), a small tree of the Myrtaceae family, is a common native of southeast
Australia and New Zealand.

Differential diagnosis
Genitalic morphology indicates that G. manuka sp. nov. is most closely related to G. rotoroa sp. nov.
from New Zealand (Fig. 15). The gonostyli, gonocoxites and ninth tergites of both species are broadly
similar, while the tegmina are completely different.

TerminaLia. Ninth tergite markedly narrowed posteriorly, posterior edge with about 20 dense megatrichia
(Fig. 19B). Gonocoxites very sparsely setose ventrally; ventral emargination lled with membrane with ne
microtrichia and setulae; ventroposterior lobes conspicuously large (Fig. 19A). Gonostylus 3.0 times longer
than broad; strongly bent on apical third; outside densely setose; inside and apex with dense microtrichia
and a few setulae (Fig. 19A). Ejaculatory apodeme shorter than in other Glemparon, as long as gonocoxites;
base weakly sclerotized; apex broadened, strongly sclerotized, merged with tegmen (Fig. 19A).
Distribution and phenology
This species is known from a single specimen collected in autumn, in a stretch of old-growth wet
eucalypt forest in lowland Tasmania.

urn:lsid:zoobank.org:act:B6B07566-CCE4-43AB-B348-5FA66F74B712
Figs 1B, 20A–D
Diagnosis
The tegmen consists of a massive, subtrapezoid portion basally and a biramous portion apically,
both separated by a constriction; the rami end in leaf-shaped processes whose bases are covered with
numerous tiny spikes (↓1, Fig. 20C). The arrow-shaped apex of the ejaculatory apodeme is sclerotized
(↓2, Fig. 20D), not membranous as in most other species of Glemparon. The gonostylus is slightly
broadened towards the apex (↓3, Fig. 20B).
Etymology
The specic epithet, warra, refers to the type locality of this species. The Warra Long Term Ecological
Research (LTER) site in southern Tasmania is a prime example of a temperate broadleaf (eucalypt) wet
forest.

The only specimen known of G. warra sp. nov. was Malaise trapped at the end of summer in the same
habitat as the previous species.
Discussion
Taxonomic descriptions based on single specimens carry the risks of misinterpreting preparation artifacts
as taxonomic characters and underestimating intraspecic variation (e.g., Jaschhof & Jaschhof 2009). In
the present study we used only perfectly prepared (slide-mounted) specimens, whose structures were not
distorted or otherwise affected during the preparation process, thereby minimizing the artifact problem.
Furthermore, genitalic structures, which provide the characters of diagnostic merit in Glemparon, rarely
vary within a species. Even so, whenever we felt that limitation of our material might pose a problem,
we interpreted our observations with special caution, such as in the case of G. waipoua sp. nov.
The genus Glemparon can serve as an example for the fact that monotypic genera are difcult to interpret
(as there is little substance available to compare with), while the discovery of a single additional congener
(here G. tomelilla sp. nov.) may function as a catalyzer for the cognitive process. This, we believe,
proves the potency of the comparative morphological method for resolving questions of character
evolution, phylogeny and classication. For example, the true nature of the tegminal longitudinal
apodemes, previously thought to be just another kind of tegminal processes (see Jaschhof & Jaschhof
2013), could be understood only by comparing its various different manifestations within a wide range
of species. Another example is the structure called here the gonocoxal posteromedial protuberance; its
complex structuring and relevance as a synapomorphy of Glemparon was only realized by comparative
examination throughout the genus. Also, the generic denition of Glemparon changed fundamentally
through the input of data from a number of newly discovered species. Last but not least, intimately
knowing as many species of a genus as possible is crucial for realizing the systematic afliation of
species whose morphology is somehow aberrant (see, e.g., G. manuka sp. nov.), for which almost all
speciose genera provide examples. In other words, describing new species matters, for they provide the
raw data for all kinds of subsequent analyses – a causal relationship whose relevance for Cecidomyiidae
and other “open-ended taxa” is sometimes questioned (see Bickel 2009).
We do not think that the disjunct, bipolar distribution of Glemparon as revealed by our study is a matter
of real facts; rather it is the consequence of our collective ignorance of Porricondylinae diversity in
most parts of the globe. Enough is known about Porricondylinae in the West Palearctic as to establish
that Glemparon are uncommon and poor in species there; however, we are much more badly informed
about the situation in the East Palearctic, not to speak about the Oriental region. At the same time there
is no doubt that Glemparon is an enormously speciose genus in the Australasian region (and possibly
even beyond), which was previously unknown. Considering that our small amount of study material was
gathered more or less randomly, one wonders what a systematic search for Glemparon in trap samples
from all over New Zealand and Australia would reveal. Our observation of ve different species co-
occurring at a single site also raises the question of how these species are adapted to different ecological
niches in the smallest spaces. Thus far, our study has generated more question marks than it has removed
– a typical situation with such basic taxonomic studies. Systematic research into Glemparon in the future
should consider using morphology along with molecular genetic evidence for characterizing species,
even though this means additional expenditures and adequately preserved specimens. As the case of
G. waipoua sp. nov. shows, not all alpha-taxonomic problems in Glemparon can be solved using alone
male adult characters.
