Abstract
The Otiorhynchus subgenus
Baldorhynchus
Di Marco & Osella, 2002 is revised and elevated to the genus level, stat. n..
The following species-level taxa were also elevated to the species level:
Baldorhynchus
caoduroi (Osella, 1983) stat. n.
from Otiorhynchus (
Baldorhynchus
) amicalis caoduroi (Osella, 1983);
Baldorhynchus
comottii (Osella, 1983) stat. n.
from Otiorhynchus (
Baldorhynchus
) moczarskii comottii (Osella, 1983);
Baldorhynchus
lessinicus (Osella, 1983) stat.
n. from Otiorhynchus (
Baldorhynchus
) amicalis cenomanus (Colonnelli & Magnano, 2003) = Troglorhynchus amicalis
ssp. lessinicus (Osella, 1983);
Baldorhynchus
toscolanus (Osella, 1983) stat. n. from Otiorhynchus (
Baldorhynchus
)
kahleni toscolanus (Osella, 1983) and
Baldorhynchus
valvestinus (Osella, 1983) stat. n. from Otiorhynchus (
Baldo-
rhynchus
) kahleni valvestinus (Osella, 1983). The following new combinations and resurrections are also proposed:
Bal-

(Troglorhynchus) serradae Colonnelli & Magnano (2003); Otiorhynchus (Troglorhynchus) radjai (Di Marco & Osella,
2002) comb. n. from Otiorhynchus (
Baldorhynchus
) radjai Di Marco & Osella (2002);
Baldorhynchus
ferrarii (F.So-
lari, 1955) nom. res. from Troglorhynchus ferrarii F. Solari (1955) = Otiorhynchus (
Baldorhynchus
) adrianoi Magnano
(2001);
Baldorhynchus

Baldorhynchus
saccoi Bellò & Osella sp. n.,
Baldorhynchus
settei Bellò & Osella sp. n. and
Baldorhynchus
tede-
schii Bellò & Osella sp. n.. Thirty-seven species are assigned to the genus
Baldorhynchus
. Finally, in addition to having
redescribed
Baldorhynchus
moczarskii (Breit, 1913), we designate a neotype for
Baldorhynchus
baldensis (Czwalina,
1875). A key to species and groups of species, a checklist of all species, diagnosis, distribution maps and details of ecology
are provided.

Riassunto
Il sottogenere di Otiorhynchus,
Baldorhynchus
Di Marco & Osella (2002), è rivisto ed elevato a livello di genere, stat.
n.. Anche i seguenti taxa vengono elevati, come livello, da sottospecie a specie:
Baldorhynchus

stat. n. da Otiorhynchus (
Baldorhynchus
) amicalis caoduroi (Osella, 1983);
Baldorhynchus
comottii (Osella, 1983)
stat. n. da Otiorhynchus (
Baldorhynchus
) moczarskii comottii (Osella, 1983);
Baldorhynchus
lessinicus (Osella, 1983)
stat. n. da Otiorhynchus (
Baldorhynchus

Introduction
Insects living in caves and underground cavities of the Lombardian Pre-alps have been, over the past thirty years,
the subject of intense investigation by Italian naturalists especially by Mario Grottolo and Riccardo Monguzzi. The
naturalists of the World Biodiversity Association (WBA), Fabio Danzi, Manfred Kahlen, Erminio Piva and Alberto
Sette, have conducted other research on the soil insect fauna, in order to improve the knowledge of the biodiversity
of Venetian Pre-alps. During this work many Coleoptera were collected, among them several specimens belonging
to Baldorhynchus (Di Marco & Osella 2002), the diagnosis of which is modified and summarized by Osella (1968,
1983), Magnano (1998), Monguzzi (1999), Di Marco & Osella (2002), and Hlaváč (2011) as follows:
a) Antennal club with basal segment flat and combined with the funicle normally not coaxially (Figs 1C, 1D);
b) Elytra convex, elongate-oval or oval, ogive-shaped on declivity and more or less unpigmented (Figs 1A, 1B);
c) Punctation of elytra and pronotum more or less deep and sparse (Figs 1E, 1F);
d) Rostrum elongate with ear-shaped scrobes (Fig. 1F);
e) Eyeless; vestigial eyes, if present, flat (Fig. 1G);
f) Femora edentate (except Baldorhynchus chiarae (Monguzzi, 1999) (Figs 1H, 1I);
g) Tooth-like tubercles on inner edge of tibiae (except Baldorhynchus settei hoc opus) (Figs 1H, 1L);
h) Lamina of sternite VIII with apical margin normally fused (Fig. 1O);
i) Genital armature of internal sac always present (as in Peritelini, see Pierotti & Bellò (1998)), with evident
sclerites (Fig. 1M).
The so-far included sixteen species or subspecies (Magnano & Alonso-Zarazaga 2013) of the Otiorhynchus,
subgenus Baldorhynchus, are distributed mainly in the calcareous mountains between the Serio River in Lombardy
and the Brenta River in Veneto. Only a single species, Otiorhynchus (Baldorhynchus) radjai Di Marco & Osella
(2002), was present in Croatia (Island Vis), but as this species has a first antennal club segment which is not flat,
we decided to consider this species as not belonging to Baldorhynchus. Based on its geographical distribution as
well as its morphological and ecological affinities, we place O. radjai to Otiorhynchus subg. Troglorhynchus F.
Schmidt (1854). This is a second hypogean subgenus of Otiorhynchus present in this area, of which five species are
currently known (Magnano & Alonso-Zarazaga 2013). Its distribution is characterized by having a more eastern
range (Hlaváč 2011). Therefore, Otiorhynchus (Troglorhynchus) radjai (Di Marco & Osella, 2002) is a comb. n.
from Otiorhynchus (Baldorhynchus) radjai Di Marco & Osella, 2002.
In the present paper twenty-one new species are described: Baldorhynchus agostianus Bellò & Osella sp. n.,
Baldorhynchus anachoreta Bellò & Osella sp. n., Baldorhynchus bodeianus Bellò & Osella sp. n., Baldorhynchus

Methods
Collecting methods. About 300 caves, underground cavities or similar places were investigated and specimens (or
remains) of
Baldorhynchus
, were found in only 88 of them. This study is based on 886 specimens, 235 belonging
to historical material already examined and 651 collected during the last thirty years. All specimens from Brescia
province (M. Grottolo and colleagues, M. Kalhen), Bergamo province (R. Monguzzi and others) and Vicenza
province (E. Piva and colleagues) have been collected in caves or old mines (hand collecting, pitfall traps), sifting
soil or were found under stones. Specimens from Mount Baldo and Trentino (M. Kalhen, G. Osella, A. Paladini and
WBA) have all been collected sifting wet soil litter in Fagus-forests or under stones deeply inserted in the soil.
Specimens from Lessinia (A. Sette) have been collected using endogean pitfall traps in soil litter, while specimens
from Monte Grappa have been found in old war galleries under stones (C. Bellò and F. Danzi).
Specimen preparation and examination. The specimens were examined using an Olympus SZH10
microscope. For each species, male and female genitalia (if available) were dissected and cleared from musculature
using standard techniques. The last two abdominal ventrites, plus penis, tegmen and sternite IX of males, and
sternite VIII, spermatheca and gonocoxites of females were dissected and mounted in Euparal®. Measurements
were taken by using an Olympus SZH10 stereomicroscope with an ocular grid, as follows: total length from base of
rostrum to tip of elytra; pronotal length from anterior margin to base in front of scutellum; pronotal width at the
widest point; elytral length from an imaginary line connecting humeri to tip; elytral width at the widest point.
Studio pictures were taken by Francesco Sacco with a Nikon D90 provided with an objective AF Micro-Nikkor 60
mm, later processed with the software Helicon Focus 5.3 and Photoshop CS4 Extended. C. Bellò with a digital
Olympus C-5050 ZOOM took field pictures. The drawings are taken from Osella (1983).
Descriptive format. A concise descriptive format is used in this study. Species descriptions are short and
emphasize diagnostic characters, or character combinations, and frequently make reference to other similar species
allowing for a quick recognition of a species. No verbose descriptions of the species are given. Similar species are
grouped into informal species groups rather than formally splitting the genus into a number of named subgenera.
Structural characteristics and distribution of species groups are given under the diagnosis of the group and are not
repeated for each species in the group. Illustrations of habitus, male and female genitalia (if available) are provided
for all species. All material examined is indicated with citation of label data, notation of the sex and depository of
the specimens. Label data is reported in full; labels are separated by double slash (//) and additional remarks are
added in rectangular brackets. Available information on elevation and habitat of collection localities is also given.
Study of 516 specimens of B. brixiensis allowed for examination of the intraspecific variability of this taxon, thus
verifying the significance of the following characters: pronotum and elytra punctation, ratio (with/length) of
pronotum and elytra, relative ratio of the funicle segments and ratio between vertex width/mesorostrum width.
These characters have then been used in the species diagnosis. For all taxa, whose dimensions were uncertain
(Osella 1983) the authors made new new measurements. The terminology of weevil characters follows Pierotti &
Bellò (2000); Morris (2002); Osella & Bellò (2010); Bellò and Baviera, (2011); Lyal (2014); Oberprieler,
Anderson & Marvaldi (2014).

Systematic Notes
Many authors starting from Schmidt (1854) and Czwalina (1875) have published studies on these species
(Troglorhynchus sensu A.A. not Di Marco & Osella, 2002) now assigned to the genus
Baldorhynchus
. In
chronological order: Bertolini (1872, 1893, 1899), Stierlin (1883), Halbherr (1896); Daniel (1903), Holdhaus
(1903), Ganglbauer (1906), Solari, A. & Solari, F. (1907), Reitter (1912, 1913, 1916), Breit (1913), Luigioni
(1929), Winkler (1932), Porta (1932), Lona (1937), Solari (1955), Conci (1956), Osella (1966, 1968, 1974, 1979,
1983), Magnano (1977, 1998, 2001), Regalin (1981, 1988), Mazzoldi (1982), Comotti (1986), Abbazzi & Osella
(1992), Caoduro, Osella & Ruffo (1994), Abbazzi, Colonnelli, Masutti & Osella (1995), Osella & Zuppa (1998),
Monguzzi (1999), Di Marco & Osella (2002), Colonnelli & Magnano (2003), Davidian & Savitsky (2006),
Abbazzi & Maggini (2009), Hlaváč (2011), Magnano & Alonso Zarazaga (2013). In the present paper, the complex
systematics of the genus Otiorhynchus will not be treated. However, Otiorhynchus and
Baldorhynchus
partially
share aspects of general morphology and distribution, on the basis of the authors experience, the genus
Otiorhynchus (type species Curculio rhacusensis Germar, 1822) (sensu Magnano & Alonso Zarazaga, 2013)
represents a polyphyletic genus, whose systematics needs to be resolved by an integrative taxonomic approach
(Padial et al., 2010). However we here consider
Baldorhynchus
, with the first segment of the club flat (not present
in other Curculionoidea) and with its well-defined distribution, as a valid genus and elevate it to the genus level.
Even the attribution of a species (B. chiarae) with toothed femora (as in Solariola Flach, 1908) (Baviera, 2015)
to the genus
Baldorhynchus
, and the division of the genus
Baldorhynchus
into seven groups of species, confirms
the importance of the unique character of the flat first article of the club. According to La Greca (1987),
“L’istituzione di una sottospecie è una operazione molto più impegnativa che non quella di istituire una specie”, the
authors consider it appropriate to create informal species-groups and at the same time consider all taxa at the
species level. We have grouped the thirty-seven species resulting from the study into seven informal species-
groups, based largely on morphology and distribution. The numbers of species in groups and distribution for each
species are in parentheses.

straight. Procoxae large, conical, connate. Mesocoxae large, separated by a space about as their diameter.
Metacoxae rather flattened, separated by a space about three times the diameter of one of it. Male genitalia. Penis
lengthened, sub-parallel seen from above and regularly and moderately curved in lateral view. Tegmen sclerotized.
Internal sac present with evident sclerites in all species. Apex of penis more or less rounded. Sternite IX sinuous at
apex with manubrium as in Fig. 1N. Female genitalia. Sternite VIII with sides sub-parallel or slightly curved;
lamina subcircular with apical margin more or less fused, bearing short setae. Spermatheca sclerotized with cornu,
ramus and nodulus more or less developed. Ovipositor weakly sclerotized, gonocoxites tapered, with short styli and
several more or less long setae.
Sexual dimorphism. To date, 21 species of 37 are surely or probably amphigonic. Males can be recognized by
their smaller size and less slender appearance, the legs stronger with a more noticeable apical mucro and ventrites 1
and 2 slightly hollowed (Figs 2, 2’, 4, 4’, 17, 17’).
Ecology. All
Baldorhynchus
species are eyeless or have vestigial eyes. Adults are usually collected in caves or
wooded environments, in limestone mountains and hills (from 100 to 1840 m at the summit of Avez) with
considerable humidity.
Baldorhynchus
, like Solariola (Baviera 2015), can be considered “old forest dwellers” and
could so be considering useful bioindicators for relatively natural and stable habitats. All weevils are phytophagous
or rhizophagous insects, so it is hardly possible to consider them true troglobionts, even when they are only known
from this environment (Osella & Zuppa 1998). Their hygrophyly and rhizophagous diet might be the reasons for
the colonization of soil and caves. Therefore, for these species, the caves act as “traps”.
Distribution. The current distribution of
Baldorhynchus
is limited to Northern Italy mainly in the hills or
mountains between the Brembo River (Lombardia) and the Piave River (Veneto) (Fig. 127). The main soils are
those with pedogenetic structure in depth and weakly differentiated profile (Eutric and Calcaric Cambisols), but
also on shallow soils of highest elevations (Lithic Cryosols), more or less shallow soils with organic matter
accumulation on the surface (Lithic, Mollic, Eutric, and Rendzic Leptosols) and alluvial soils (Eutric Fluvisols)
(FAO/IIASA/ISRIC/ISSCAS/JRC, 2012).

Genitalia of seven specimens (four males and three females) were examined.
Distribution. See Fig.128. Italian endemic. Only known from Mount Baldo and Lessini.
Ecology/Phenology. See Osella (1966, 1968). We collected the species while sifting in deep moist litter in a
beech forest near the fountain of Teja.
Reproduction. Amphigonic.
Systematic notes. Seidlitz (1894) wrote that after the death of Czwalina, his collection was forwarded to the
Zoological Museum in Königsberg (now Kaliningrad, Russia). This Museum unfortunately was destroyed during
World War II and all collections were relocated or lost (Solodovnikov 2001). Despite various attempts, the type has
not been found. It is not in the collection of the Naturhistorisches Museum in Wien, Austria (Harald Schillammer,
pers. comm.), nor in the Museum of Natural History in Berlin, Germany (Johannes Frisch, pers. comm.) and also
not traceable in the collections of other museums controlled by us (MSNM, MSNV, MTSN, NHMB, TLMF). The
original description (Czwalina 1875) allows the unambiguous recognition the species, and according to the rules
art. 75 of the International Code (ICZN, 1999) we here select and designate a neotype.

Ecology/Phenology. See Osella (1983). Monguzzi (in verbis) reports that during one of his research in the
"Bus of the Sete Stanse", the inner part of the cave (where many roots are hanging from the ceiling), was covered
by hundreds of dead B. brixiensis, which were collected using wet cotton.
Reproduction. Parthenogenetic. All 516 specimens examined were females.
Notes. In the hundreds of specimens examined, except for the size, no significant differences in the shape and
ratio length/width of elytra and pronotum, funicle segments in the ratio, the vertex width/width ratio mesorostrum
and punctation of the elytra and pronotum have been observed. The color of the cuticle, however, can vary,
depending on emergence period of the specimens, from yellow to brown-red pigmentation. Only one
morphologically aberrant specimen has been recorded, having a very short rostrum.

maximum width in the anterior third; short golden erect seta inserted in center of hole; punctation impressed,
isodiametric and of different widths, not uniformly arranged; smooth central area on disc. Scutellum small,
excavated, triangular. Elytra convex, elongate with high suture (length: 3.20 mm, width: 1.70 mm, ratio: 1.88),
strongly rounded on sides, widest at middle and strongly oval shaped. Punctation striae not deep, isodiametric and
not same widths, without setae; interspaces between strial punctation smooth and regular, wider than hole.
Interstriae less wide than striae, flat, smooth with sparse, long and erect setae. Legs thin and elongate, with rather
long golden setae. Femora clubbed and edentate. Tibiae with seven/eight tooth-like tubercles on inner edge;
protibia slightly curved in side view, metatibia and mesotibia straight. Penis lengthened, sub-parallel seen from
above and regularly curved in lateral view; tegmen sclerotized; small genital armature; penis apex as in Fig. 17f.
Female. The female paratype is recognizeable from the male paratype by its larger size, the more slender body,
the funicle segments less elongate, more slender legs with apical mucro of the tibiae less evident, and ventrites 1
and 2 slightly convex. Sternite VIII with sides curved of lamina and with apical margin fused. Spermatheca with
cornu developed, ramus and nodulus inconspicuous (Fig. 17f). Ovipositor weakly sclerotized, gonocoxites tapered,
with short styli and several more or less long setae.
Distribution. See Fig.130. Italian endemic. Known only from at 1050–1070 meters of elevation: 45°50.308’N,
011°45.146’E at “Monte Grappa” in Col Campeggia near Romano d’Ezzelino (Vicenza) (Fig.). The gallery opens
on a steep slope southeast of the Grappa massif towards Santa Felicita Valley.
Etymology. Named for friend and colleague Fabio Danzi whose research on the fauna of the Grappa
Mountains made the discovery of this interesting species possible.
Ecology/Phenology. The specimens were collected under stones in a gallery of World War I placed in a beech
forest with very shallow soil. Like all
Baldorhynchus
, this species finds its habitat more favorable in the endogean
environment. Although its biology is unknown, it is very likely that B. danzii it is rhizophagous and humicoulus
because numerous roots were hanging from the vaulted ceiling of the Gallery.
Reproduction. Amphigonic.

Systematic notes. After the examination of the type of B. carinatus, we agree with Osella (1983) that the two
species (B. carinatus and B. ferrarii) belong to the same species group and that B. carinatus is similar to B. ferrarii.
Moreover, also the geographical distribution falls within the current distribution of the B. ferrarii group.
Baldorhynchus
carinatus (Osella, 1983) is nom. res. from synonymy of Troglorhynchus carinatus Osella (1983)
with Otiorhynchus (Troglorhynchus) serradae Colonnelli & Magnano (2003), replacement name based on
homonymy with Otiorhynchus (Podoropelmus) carinatus (Paykull, 1792).

Ecology/Phenology. Specimens of this species were collected digging rootlets under a walnut tree, Regalin (in
litteris, 2013). Regalin (in litteris, 2014) wrote: “Ricordo anche di aver raccolto delle larve (due) nello stesso
microambiente dove vivevano gli adulti, ovvero nel terriccio nero dove c'erano le radichette della pianta di noce
che cresceva presso l'ingresso della cavità” (I also remember that he had collected the larvae (two) in the same
microenvironment where lived adults, that is, in the black soil where there were rootlets of the walnut tree that
grew near the entrance of the cave). Recorded temperature for presence of alive specimens was 8.3 C° Regalin,
1988.
Reproduction. Probably parthenogenetic. Species known only from four females.
Additional localities for future research
In addition to the specimens cited above, we examined several
Baldorhynchus
remains (all females) from 29
different localities, all identified at the species-group level. Moreover, on the basis of literature (Osella 1966, 1968;
Regalin, 1981, 1988; Mazzoldi, 1982; Comotti, 1986) an additional five localities originally ascribed to
Troglorhynchus sp. could be assigned to
Baldorhynchus
sp.. Therefore, in order to facilitate and encourage further
investigation, we provide herein the list of all the localities. Very probably further research focused on this genus
will identify additional new taxa.

Remarks
The present work allowed the authors to elevate
Baldorhynchus
(Di Marco & Osella, 2002) to the genus level and
increase the number of known species from 16 to 37, grouped in seven informal species groups. Moreover, the
original distribution of this genus has been considerably extended, from the Brembo River valley to the Piave River
valley, reflecting the real range of distribution of the genus (fig. 127). However, some areas still require further
investigation (Venetian Prealps and Lessinian-Beric areas). The discovery of twenty-one new species in a relatively
limited and well-investigated area confirms once again the richness of Italian biodiversity. It is clear, without any
doubt, that extensive, and focused research for
Baldorhynchus
, whose presence and distribution is strictly related
to the roots they feed on (Giachino & Vailati, 2010), will result in further and important faunistic discoveries.
