Abstract and Figures

Nine new species of Colastomion Baker are described, illustrated and keyed based on series of specimens reared from caterpillars of crambid moths from lowland Papua New Guinea plus one additional field collected specimen, viz. C. cheesmanae Quicke sp. n., C. crambidiphagus Quicke sp. n., C. gregarius Quicke sp. n., C. maclayi Quicke sp. n., C. madangensis Quicke sp. n., C masalaii Quicke sp. n., C. parotiphagus Quicke sp. n., C. pukpuk Quicke sp. n. and C. wanang Quicke sp. n. Most species are morphologically easily distinguished but DNA barcoding additionally reveals a pair of exceedingly similar species (C. pukpuk sp. n. and C maclayi sp. n.) that might otherwise have gone unrecognised. The new species each appear to be relatively specialised on their host species and all parasitize only caterpillars of Lepidoptera: Crambidae: Spilomelinae.

Introduction
Colastomion Baker (1917) is a relatively uncommon genus of rogadine parasitic wasp
that occurs throughout the southern East Palaearctic, S. E. Asia and Africa. It belongs
to a group of genera which additionally includes the tropical Old World genera Cysto-
mastacoides van Achterberg, Macrostomion Szépligeti, Megarhogas Szépligeti and Myo-
cron van Achterberg (1991) all of which share a more or less deep and ventrally strongly
curved hypopyium with a strongly down-curved ovipositor (also present in various
other SE Asian genera). Until recently nothing was known about its biology though
Macrostomion has been reared from various Sphingidae caterpillars within which it is
gregarious with 20–50 individuals typically emerging from a single mummied host
larva (Shaw 2002, Maeto and Arakaki 2005).
To date, only six species of Colastomion have been described, viz. C. abdominale
Baker (1917) from the Philippines, C. bicoloricorne (Granger 1949) from Madagas-
car, C. concolor (Szépligeti 1911) originally described from Tanzania and subsequently
reported from Democratic Republic of Congo, Madagascar, Malawi and Togo (Yu et
al. 2005), C. formosanum Watanabe (1932) originally described from Taiwan, but re-
cently recorded from Japan (Tenma 2002), C. nigricorne (Granger 1949) and C. tristis
(Granger 1949) both from Madagascar.
Here we describe nine new species of Colastomion, eight of which are based on
reared specimens from caterpillars feeding on various trees and shrubs in lowland Pap-
ua New Guinea. ese were obtained during an extensive caterpillar collecting and
rearing programme which has additionally yielded a number of other interesting roga-
dine parasitoids including the recently described, highly distinctive genus Vojtechirogas
Quicke & van Achterberg (Quicke et al. 2012).
e host records for some of the species include a degree of fuzziness because iden-
tications are based on caterpillar morphology. e actual parasitized caterpillars of
course never produce an adult moth, and so there is always some degree of uncertainty
with host records acquired by rearing. Because in the course of the New Guinea rear-
ing programme there were several hundred thousand caterpillars reared, we are able
to quantify the inevitable uncertainty. For any reared specimen we present only host
records which are at least 95% sure, i.e. at least 95% of the tens or hundreds of moth
adults reared from the same combination of caterpillar morphotype and host plant as
the parasitoid agree with the reported host identication. Two rearing records for C.
masalaii sp. n. and C. parotiphagus sp. n. were conrmed by sequencing host remnants
(Hrcek et al. 2011).

e systematics of several of the moth taxa involved here, all of which belong to the
crambid subfamily Spilomelinae, is also far from complete and there is no meaningful
phylogeny as yet. us some genera may well be poly- or paraphyletic assemblages, and
in these cases we have sometimes been able to assign hosts to species groups, that in the
future may shift into other generic combinations.
Terminology
Terminology follows van Achterberg (1979, 1988). Measurements of the height and
horizontal length of the eye are approximations because the very bulbous face and very
large eyes make it dicult to measure consistently; in our attempts to do so, the head
was orientated so that the face (dened as running from the anterior edge of the toruli
to the dorsal margin of the clypeus) was horizontal or perpendicular to the measure-
ment axis.
Abbreviations: NHM (e Natural History Museum, London); USNM (United
States National Museum, Washington D.C.). Note, some paratypes will be repatriated
to PNG when analysis is complete.
Methodology
Phylogenetic inference and bar-coding discrimination of species were based upon max-
imum likelihood (ML) analysis of approximately 657 base pairs of the 5’ end of the
mitochondrial cytochrome oxidase I gene, using the programme RAxML (Stamatakis
2006) with the GTRGAMMA model and using a sequence from the related genus
Myocron van Achterberg as outgroup. DNA sequencing was performed at the Biodiver-
sity Institute of Ontario, University of Guelph, using their standard methods (Hrcek
et al. 2011).
Most specimens were imaged using Cell^D® imaging facility. C. gregarious sp. n.
and C. cheesmanae sp. n. were imaged using a Canon EOS 7D camera, Adobe Light-
room software and edited using Adobe Photoshop CS4.
Results
DNA barcodes were generated from all but one of the species described below, the ex-
ception being a nearly 80 year old specimen found in the NHM collection. Fig. 1 shows
a ML tree from these, with eight clearly separated molecular species, and intraspecic
variation was limited to two individuals of C. masalaii sp. n. (vouchers USNM ENT
00503254 and 00643295) diering from the remainder at a single base position.

Notes. Four specimens with host data from a dierent locality and host tree but
lacking barcoding data probably belong to this species but are excluded for the above
reason from the type series. We can nd no convincing morphological dierence be-
tween them and the holotype of C. wanang sp. n. though they do have the 1

Biology. Solitary endoparasitoid of Meekiaria (Crambidae) caterpillars on Psycho-
tria sp. (Rubiaceae). Meekiaria have distinctive male genitalia with numerous closely
related species in PNG (Munroe 1974, Craft et al. 2010: S2).
Etymology. Named after Nicholai Miklucho-Maklaj, a Russian explorer of New
Guinea who lived around the Madang area for some time.
Discussion
e species described here comprise three groups based both on morphology and
DNA (Fig. 1). Colastomion gregarious sp. n., C. madangensis sp. n. and C. masalaii sp.
n. are all small, at least facultatively gregarious species with an antefurcal fore wing vein
cu-a (Fig.15) and an inverted ‘V’-shaped carina on the propodeum (Fig. 7); C. cram-
bidiphagus sp. n. and C. parotiphagus sp. n. are medium-sized, predominantly yellow
species; C. cheesmanae sp. n., C. maclayi sp. n., C. pukpuk sp. n. and C. wanang sp. n.
are all large, black headed species with largely black metasomas with whitish tips. e
amount of morphological variation observed between these three groups of species is
considerable, and might in the past have been deemed sucient by some taxonomists
to warrant division into dierent genera or subgenera, and the relatively long internal
branches on the molecular phylogeny support their high level of dierentiation. Ad-
dition molecular studies on the whole subfamily will be needed to determine whether,
despite the vertical hind wing vein 2-SC+R, these taxa form a natural group to the
exclusion of other members of the complex.
As with many rogadine wasps, Colastomion had no published host records prior
to the current caterpillar rearing campaign in Papua New Guinea, despite it being
widely distributed and occurring also in tropical Africa and S. E. Asia. In common
with the closely related genus Macrostomion Baker, several of the new species de-
scribed here are gregarious. is biology is unusual among the Rogadinae. A few
species of the cosmopolitan genus Aleiodes Wesmael are gregarious (specically A.
pallescens on various Notodontidae, A. stigmator (Say) on Noctuidae, and A. leptoca-
rina Fortier on an unidentied hairy host caterpillar). Another aspect of the gregari-
ousness exhibited by some Colastomion is that the brood size is rather small, and at
least one of the new species, C. masalaii sp. n., is facultatively gregarious. us they
may make interesting study organisms for investigating the evolutionary transition
New reared rogadine wasp species from New Guinea 119
from solitary to gregarious life histories (Mayhew and van Alphen 1999, Mayhew
and Glaizot 2001, Guinee et al. 2005).
It is interesting that all the reared Colastomion species are parasitoids of Crambidae,
though these collectively feeding on a wide range of host plant families. Few tropical
genera of Rogadinae have multiple host records, but of those that do, several appear to
be relatively restricted in the range of host families attacked suggesting at least some de-
gree of co-evolutionary tuning between host defence mechanisms and the parasitoid’s
ability to overcome them. However, before this can be investigated much further, a far
larger body of host-parasitoid association data will be required.

... The principally tropical generic diversity had been rather poorly studied until van Achterberg (1991), Chen & He (1997) and Shaw (1997b) revised the Afrotropical, Chinese and New World genera, respectively. These works collectively described six new genera and provided a useful genus-level framework, which led to further studies recognizing several more new genera (Chen et al., 2004;Braet & van Achterberg, 2011;, 2015Quicke et al., 2012aQuicke et al., , 2014Butcher & Quicke, 2015a, Sharkey et al., 2021, new species Quicke et al. 2012b;Butcher et al. 2014;Long, 2014;Butcher & Quicke, 2015b;Sharkey et al. 2021) and new host records (Shaw, 2002;Maetô & Arakaki, 2005;Quicke & Shaw, 2005a,b;Quicke et al. 2012aQuicke et al. , 2012bQuicke et al. , 2012cSharkey et al. 2021).

... The available biological data for these are limited. Several Colastomion from Papua New Guinea and Japan have been reared as solitary or gregarious parasitoids of Crambidae (Quicke et al., 2012b;Sakagami et al., 2020), whereas all records for Macrostomion are as gregarious parasitoids of Sphingidae (Shaw, 2002;Maetô & Arakaki, 2005). Based on morphology alone, it would not seem unreasonable to synonymize Old World Colastomion, Macrostomion and Megarhogas since the characters separating them are either rather weak and likely homoplastic (Colastomion and Macrostomion) or, in the case of Megarhogas, only separated by one clear autapomorphy of fore wing venation (a swollen junction between fore wing veins r-rs, 3RSa and 2RS). ...

A molecular phylogeny of the subfamily Rogadinae is presented for 469 species in 52 genera representing all tribes and subtribes. The data comprise cytochrome c oxidase I sequences (DNA barcodes), together with a broad representation of 28S rDNA D2-D3 expansion region, EF1-α gene and 16S rDNA fragments. To test monophyly, most genera were represented by multiple species. The analysis of the complete dataset recovered a monophyletic Rogadinae with low support. All six tribes were recovered as monophyletic with the following relationships: (Rogadini, (Stiropiini, (Clinocentrini, (Betylobraconini, [Yeliconini, Aleiodini])))). Three new genera are recognized: Afrorogas Quicke gen.n. (type species Afrorogas copelandi Quicke sp.n.) for a mainland Afrotropical species; Amanirogas Quicke gen.n. (type species Amanirogas isolatus Quicke sp.n.), previously treated as a Rogas species from Tanzania; and Papuarogas Quicke gen.n. (type species P. dameni Quicke sp.n.), for species from Papua New Guinea. Iporhogas Granger is synonymized with Troporhogas Cameron. The African genera Myoporhogas Brues, Scoporogas van Achterberg and the endemic New Zealand genus Rhinoprotoma van Achterberg are synonymized with Aleiodes. A formal diagnosis of the Aleiodini Muesebeck is provided for the first time.

We report the solitary parasitism by Colastomion formosanum (Watanabe) (Hymenoptera, Braconidae, Rogadinae) on the larva of Nevrina procopia (Stoll) (Lepidoptera, Crambidae) feeding on Turpinia ternata Nakai (Staphyleaceae) in Amami Ôshima Is., Japan. This is the first host record for the genus Colastomion Baker outside of Papua New Guinea. We have also inferred the phylogenetic relationships of Colastomion species using Bayesian and maximum likelihood approaches, based on the mitochondrial cytochrome oxidase 1 gene. The results indicate two major clades–solitary and gregarious parasitoids–within Colastomion. Colastomion formosanum belongs to the clade of solitary parasitoids that specifically parasitize the crambid subfamily Spilomelinae. Plant-host-parasitoid associations and the evolutionary scenario of the host use of Colastomion are discussed.
... The Rogadinae is one of the largest subfamilies of Braconidae, and is especially diverse but poorly understood in the tropics. Recently, several rogadine genera of the New World, Africa and China have been treated (van Achterberg 1991; Chen & He 1997;Shaw 1997;Butcher et al. 2012;Quicke et al. 2012), and several new genera were erected (van Achterberg 1991;van Achterberg & Chen 1996;Belokobylskij 1999;Chen et al. 2004;Long & van Achterberg 2008;Quicke & Butcher 2011;Long et al. 2018). ...

The relatively small genus Colastomion Baker, 1917 is newly recorded for Vietnam’s braconid fauna and six new species are described and fully illustrated, viz. Colastomion asperum Long, sp. n; Colastomion cephonodes Long & PVLam, sp. n.; Colastomion citrum Long, sp. n.; Colastomion neuterum Long, sp. n.; Colastomion nigroconfusum Long & Pham, sp. n. and Colastomion vietnamenese Long, sp. n. Based on both females and males, a key to the new species from Vietnam is given. Diagnostic characters of the new species are also analyzed and compared with other Colastomion species from the Oriental region. Additionally, the first host record for the new species, C. cephonodes sp. n., is provided as this new species is reared from caterpillars of the coffee hawkmoth, Cephonodes hylas (Linnaeus, 1771).
... They are highly diverse koiniobiont endo or ectoparasitoids of lepidopteran larvae or even leaf-rolling crickets (Chen and van Achterberg 2019). Both solitary and gregarious parasitoidism occur in the Rogadinae (Maetô and Arakaki 2005;Quicke et al. 2012). Biologically, the larvae of all members of the Rogadinae (sensu stricto) are believed to mummify their host larvae (Zaldívar-Riverón et al. 2008). ...

The Iranian species of the genus Clinocentrus Haliday are reviewed. Clinocentrus amiri Rakhshani & Farahani sp. nov. is described and illustrated. The new species was collected exclusively using light traps and it is most probably a nocturnal species. It was found in association with Tamarisk forests around the Hamoon wetlands. A brief diagnosis is provided for the previously recorded species of Clinocentrus in Iran, with an illustration of their morphological characters, and the similarity of the new species to the genus Artocella van Achterberg is discussed.
... Members of Aleiodini, which is mainly represented by the enormous genus Aleiodes, utilize a broad range of host families, mainly attacking species of a variety of apoditrysian superfamilies as Gelechioidea, Zygaenoidea, Lasiocampoidea, Geometroidea and Noctuoidea, among others (Shaw, 2002a;Quicke & Shaw, 2005;Fortier, 2006;Bazinet et al., 2013;Mitter et al., 2017). Members of Rogadini also attack a broad range of lepidopteran groups including several apodytrisian superfamilies, notably Bombycoidea, Drepanoidea, Geometroidea, Noctuoidea, Papilionoidea, Pyraloidea, Sphingoidea and Zygenoidea (Austin, 1987;van Achterberg, 1991;Shaw, 2002b;Quicke & Shaw, 2005;Quicke et al., 2012). The hosts of both Aleiodini and Rogadini are typically fully exposed or poorly concealed (Shaw, 2006;Hrcek et al., 2013). ...

Rogadinae are a cosmopolitan, species-rich braconid wasp subfamily whose species are endoparasitoids that attack larvae of a number of lepidopteran families. Members of this subfamily are characterized by pupating within the mummified host larval skin. The subfamily contains six tribes whose relationships have only been partially clarified: Aleiodini, Betylobraconini, Clinocentrini, Rogadini, Stiropiini and Yeliconini. The limits and composition of the closely related subfamilies to the Rogadinae, Hormiinae and Lysiterminae, also remain unclear. Here, we generated ultraconserved element data to reconstruct an almost fully resolved phylogeny for the members of Rogadinae and related subfamilies. Based on our best estimate of phylogeny, we confirm the monophyly of Rogadinae including Betylobraconini, synonymize Xenolobus Fahringer and Bequartia Cameron within the species-rich genus Aleiodes Wesmael (syn.n.) based on DNA, and synonymize Promesocentrus van Achterberg with Pilichremylus Belokobylskij (syn.n.) based on morphology. We also consistently recovered Hormiinae and Lysiterminae as not reciprocally monophyletic, and thus propose to unite their members under Hormiinae. The ancestral host preference for Rogadinae was probably attacking concealed lepidopteran larvae, with the occurrence of at least two main subsequent transitions to attack both concealed and exposed hosts, one within Rogadini and a second within Aleiodini. We highlight the importance of natural history collections as a source for conducting genomic-based studies using techniques that allow to obtain a substantial amount of data from considerably old preserved insect specimens.
... Whilst traditional collecting techniques such as Malaise trapping have led to the discovery of many new species, rearings of parasitoids from either known hosts or particular types of substrate have also contributed to our knowledge, quite often yielding species that have not been obtained by other techniques (e.g. Quicke et al., 2012Quicke et al., , 2016. ...

During an investigation of the insect food web in Papua New Guinea several specimens of a new genus and species of large, black and orange braconine braconid wasp were reared from fruits of Rubiaceae. These are described here as Karposibracon papuensis Quicke & Butcher gen. et sp. nov. Karposibracon gen. nov. appears to belong to the tribe Braconini and is the largest known species in this group, with body length up to 12 mm. The new genus is illustrated photographically, distinguished from other genera, and comments are on its likely biology provided.

Troporhysipolis gen. nov. with four included species is described and illustrated. The type species, Clinocentrus antefurcalis Granger, 1949, is Afrotropical with unknown biology. We additionally recognise three new species from eastern lowland of Papua New Guinea, T. brenthiaphagus sp. nov., T. markshawi sp. nov. and T. molecularis sp. nov., all three of which were reared from leaf-rolling larvae of the family Choreutidae (Lepidoptera). The genus can be distinguished by the combination of fore wing vein cu-a (nervulus) being antefurcal and the second subdiscal (brachial) cell subparallel-sided, widened and formed of mainly thickened veins. The new genus is tentatively placed in the Rhysipolinae based on the arrangement of the occipital and hypostomal carinae, and partly on molecular phylogenetic analysis using the barcoding cytochrome oxidase 1 gene fragment and the D2 variable region of nuclear 28S rDNA. T. molecularis sp. nov. hardly differs from T. brenthiaphagus sp. nov. morphologically and is distinguished primarily based on its barcoding sequence data.

Townes described an early fossil ichneumonid, Tanychora petiolata, from early Cretaceous amber of Russia, which is still the earliest known probable member of the Ichneumonidae dating to 121–125 Mya. This chapter talks about the phylogeny and systematics of the Ichneumonidae. Tanychora shows several plesiomorphic features and has been important in interpreting various characters in modern taxa. The Brachycyrtiformes was an almost completely unsuspected clade until molecular data became available. It includes four small subfamilies, the cosmopolitan Brachycyrtinae, together with two small groups occurring in Chile (Clasinae and Pedunculinae) and Australia (Pedunculinae), and was named the brachycyrtiformes by Quicke et al. A close relationship between many of the subfamilies of the Ophioniformes was suspected back in the 19th century, based largely on the laterally compressed metasomas with the spiracle of the first metasomal tergite being placed well behind the middle as in Ophioninae, Anomaloninae, Campopleginae, Cremastinae and Tersilochinae.

Specimens of the subfamily Rogadinae (Hymenoptera: Braconidae) were collected in northern Iran during 2010–2011 with a series of Malaise traps. Twelve species belonging to three genera (Aleiodes Wesmael, 1838, Heterogamus Wesmael, 1838 and Clinocentrus Haliday, 1833) were identified, with one genus (Heterogamus) and seven species new for the fauna of Iran. An updated checklist of the genera and species of the subfamily Rogadinae is included. A total of 26 species belonging to four genera are listed for Iran after correction for misidentifications. A key to the genera and the species of Rogadinae known from Iran is provided.

Macrostomion gnathothlibi spec. nov. is described from a series reared gregariously from a larva of the sphingid moth Gnathothlibus eratus eras (Boisduval) collected in Papua New Guinea. Dedanima Cameron, 1903, is synonymised with Macrostomion Szépligeti, 1900. A further four gregarious broods of Macrostomion are noted, three certainly and one probably reared from mummified larvae or prepu-pae of Sphingidae, from which it appears that Macrostomion species may all be gregarious parasitoids of Sphingidae.

Citation: Butcher BA, Smith MA, Quicke DLJ (2011) A new derived species group of Aleiodes parasitoid wasps (Hymenoptera, Braconidae, Rogadinae) from Asia with descriptions of three new species. Abstract Three new species of Asian Aleiodes are described and illustrated: A. spurivena sp. n. from Vietnam, Thai-land, Nepal and India; A. spurivenaduplus sp. n. from Vietnam; A. spurivenatriplus from Western Malay-sia. The first two of these are differentiated based on the bar-coding, 5' region of the cytochrome oxidase 1 gene. All three are morphologically extremely uniform and can be recognised from other Aleiodes species by the presence of a reclivous spur arising from fore wing vein 1–1A.
