Introduction
The cosmopolitan Rogadinae Förster, 1863 is one of the most diverse subfamilies of Braconidae, with more than approximately 1,200 described species and 54 genera worldwide (Yu et al. 2016; Quicke et al. 2021). Of these, 16 Rogadinae genera occur in the New-World regions and 50 in the Old World tropics. Regarding its described species, it is the third most diverse subfamily in South East Asia (SEA) with 196 species known for Thailand (Songvorawit et al. 2021), while in contrast, only 36 species were reported for India (Yu et al. 2016; Ranjith et al. 2018, 2022; Rishabanu et al. 2021); the large former number is largely due to a single revisionary work on one huge genus by Butcher et al. (2012).
Rogadine wasps are koinobiont endoparasitoids that attack caterpillars in several groups (Zaldivar-Riverón et al. 2008; Quicke et al. 2021). When the rogadine wasp has completed its development, the host caterpillar is easily recognised because it is mummified and usually found attached to its host plant (van Achterberg 1991; Zaldivar-Riverón et al. 2008; Quicke 2015). This biological trait makes the subfamily particularly useful for the study of host-parasitoid associations, because the caterpillar’s remains can often be identified based on morphology (van Achterberg et al. 2020) or molecular techniques (Quicke et al. 2012). Unfortunately, there are no biological data as yet for the genus Troporhogas.
Until recently, specimens from the Indo-Malayan region were referred to under the generic name Iporhogas Granger, 1949, which was originally described from Madagascar based on a single species. Troporhogas Cameron, 1905, was originally described from Sri Lanka; however, it was subsequently referred to only in catalogues, and species from SEA and southern China were described under the name Iporhogas. The two genera were formally synonymised by Quicke et al. (2021) based on a molecular phylogenetic study in which a Sri Lankan specimen of T.ruficeps Cameron, closely related to T.tricolor, the type species of Troporhogas, was deeply nested in a clade with species that had been assigned to Iporhogas (Chen and He 1997; Long 2014). We illustrate here the type species of the genera Troporhogas and Iporhogas here in Fig. 1. The type species of Troporhogas, T.tricolor, has a distinct mid-longitudinal carina on the median area of the metanotum (Fig. 1E), whereas this is absent in the type species of Iporhogas (Fig. 1O).

Troporhogas was originally described based on seven species, all from Sri Lanka, viz.: T.albipes, T.lateralis, T.maculipennis, T.ruficeps, T.spilonotus, T.tricolor, and T.trimaculatus (Figs 2, 3). Of these, T.maculipennis was transferred to Megarhogas by Baltazar (1972). Troporhogasspilonotus was transferred to Pseudogyroneuron Baker, 1917, by Baltazar (1972) and then to Canalirogas van Achterberg & Chen, 1996, by Quicke and Shaw (2005) and subsequently treated as a senior synonym of C.balgooyi van Achterberg & Chen, 1996 (van Achterberg and Chen 1996) by Long and van Achterberg (2015). Troporhogaslateralis was formally transferred to Rogas, often regarded as a senior synonym of Aleiodes, and then to Aleiodes by Broad (2021); in the same paper, Broad designated a lectotype for T.trimaculata.

Members of Troporhogas can be recognised by the key provided in Chen and He (1997) in which they will key to Iporhogas. Many Troporhogas species have a distinctive habitus together with a bicoloured metasoma, black medially on some tergites (mainly on TT1–5) and white, especially on the anterolateral areas of the tergites (Long 2014), but in others it may be uniformly honey-coloured to ochraceous.
Chen and He (1997) recorded the genus for the first time from China, and described five new species, and Long (2014) recorded it from Vietnam and described an additional four species, all of these under the generic name Iporhogas.
Here we describe six more new species, T.anamikae sp. nov. from India, and T.alboniger sp. nov., T.benjamini sp. nov., T.hugoolseni sp. nov., T.rafaelnadali sp. nov., and T.rogerfedereri sp. nov. from Thailand, bringing the total number of Troporhogas species known worldwide to 20. This is the first report of Troporhogas from India and T.contrastus (Long 2014) and T.tricoloratus (Long 2014) are recorded from Thailand for the first time. A key is provided to enable recognition of all non-Afrotropical species. Further, since the original descriptions of the Chinese species, despite being quite thorough, were only illustrated with a few line drawings, we present photographs of the type specimens to facilitate use of the key. Phylogenetic relationships among all species of Troporhogas for which DNA data are available were also reconstructed based on four gene markers: cytochrome c oxidase subunit 1 (COI), cytochrome b (Cyt b), 16S rDNA, and the D2-D3 expansion region of 28S rDNA.
Materials and methods
Specimens were collected with light traps at Doi Phu Kha National Park, Nan and Nakhon Ratchasima, with Malaise traps at Khao Yai National Park, Thailand, and by sweep net from secondary forests at Janakikkad, Kerala, south India.
The holotypes of T.alboniger sp. nov., T.benjamini sp. nov., T.hugoolseni sp. nov., T.rafaelnadali sp. nov. and T.rogerfedereri sp. nov. were imaged using a Leica M205 C with Montage multifocus, interactive measurement and fusion optics stereo microscope, using the Leica Application Suite (LAS). Holotype images of T.anamikae sp. nov. were taken using a Keyence VHX-6000 digital microscope. Raw figures were edited with the program GIMP v. 2.10.

Terminology follows van Achterberg (1988) except for wing venation which follows Sharkey and Wharton (1997) and Butcher and Quicke (2023). Metasomal tergite/tergites are abbreviated as T/TT.
Molecular methods
A molecular data matrix was created comprising up to four gene regions: barcoding region of cytochrome oxidase c subunit 1 (COI), cytochrome b (386 base pairs) (Cytb), regions IV and V of the mitochondrial 16S rRNA gene from H2507 to H1792′ (~ 650 bp), and the D2-D3 expansion region of 28S rDNA (28S). Most sequences (one sequence of the new species T.benjamini, T.rafaelnadali, and T.rogerfedereri and sequences of T.contrastus, T.ruficeps, T.tricoloratus, Troporhogas spp. 1–5, Papuarogasdameni, Rogasodes spp. 1 and 2, and Rogasella sp. 3) are taken from Quicke et al. (2021) and were generated from wasp legs by the Centre for Biodiversity Genomics, University of Guelph, based on standard protocols as described in Hebert et al. (2003), Park et al. (2010), and Quicke et al. (2023). In addition, we included sequences from representatives of three closely related species belonging to the genera Papuarogas Quicke, 2021, Rhogasella Baker, 1917, and Rogasodes Chen & He, 1997 as outgroups based on the large phylogeny presented by Quicke et al. (2021). Most of the Cytb sequences are newly generated.
Alignment of both COI and cytochrome b sequences was trivial as there were no indels. The length-variable 28S sequences were aligned according to the secondary structure model of Gillespie et al. (2005) as in other studies (Butcher et al. 2014; Quicke et al. 2016) and the length-variable 16S sequences were aligned according to the secondary structure models (Buckley et al. 2000; Wu et al. 2014). For both COI and Cytb, the three codon positions were each treated as a separate partition. For both 16S and 28S, only confidently aligned base pairs were included and each was treated as a single partition.
Maximum likelihood (ML) trees were constructed using RAxML v. 7.0.4 (Stamatakis 2014) with the GTRGAMMA model and a rapid bootstrap (100 replicates) using the options -m GTRGAMMA -f a -# 100 command. Tree was visualised using FigTree v. 1.4.4. (Rambaut 2018).
Provenances of sequenced specimens, DNA barcode index numbers (BINs), and GenBank accessions numbers are given in Suppl. material 1. In addition, the colour pattern on metasomal tergite of Troporhogas is provided in Fig. 21.

Phylogeny
The maximum likelihood tree obtained is shown in Fig. 4. Troporhogas was recovered as monophyletic with 100% bootstrap support. The circles at nodes indicate rapid bootstrap clade support. The genus comprised two separate clades each with 100% bootstrap support, one including all the Afrotropical species and the other all Indo-Australian species. Six of the Thai species and the one from India form a monophyletic group with 79% bootstrap support. Of these, T.rafaelnadali sp. nov. and T.tricoloratus were both supported ≥ 99%. The most basal member of the Asian clade was T.rogerfedereri sp. nov., a species that appears most closely related, on the basis of morphology, to the Chinese T.flavistigma, both sharing five carinae in the scutellar sulcus and anteriorly widely-separated submedial longitudinal propodeal carinae anteriorly (Figs 16G, 19F). However, within the remainder of this clade there was little support for the additional species recognised by morphological characters, especially for T.alboniger sp. nov. and T.contrastus Long and our reasons for recognising this new species are dealt with below.

Diagnosis.
Troporhogasalboniger sp. nov. can be differentiated from all other species by its colour pattern, the female being bicoloured (black and white), its body without any yellow or brownish yellow colouration. Head black except area around the mouthparts including palps white. The mesosoma is completely black except for white tegular area. Metasoma bicoloured: TT1, 2, and 6 white, TT3–5 black (with white spot on the middle of posterior area of fifth tergite). Molecularly (Fig. 1) and morphologically it is closest to T.contrastus (originally described from Vietnam) which displays a very different colour pattern, having the head and anterior mesosoma yellow. Apart from colouration, T.alboniger sp. nov. differs from T.contrastus in (1) having fewer flagellomeres (41 cf. 45, 46); (2) anterior margin of mesopleuron a little below antescutal depression with zone of fine subvertical striation with (Fig. 7B, E; white arrows) compared with a few, irregular somewhat longitudinal rugae (Fig. 7B, E; white arrows); (3) posteromedial part of mesopleuron above precoxal sulcus with more or less round setiferous pits (Fig. 7B, E; yellow arrows) compared with distinctly elongate pits (Fig. 7B, E; yellow arrows); (4) anteromedial area of propodeum adjacent to anterior areola with smaller and more widely spaced setiferous punctures (Fig. 7C) compared with a denser zone of deep large setiferous punctures (Fig. 7F).

Notes.
The female Thai specimen agrees very well with the original description except that the dark mark at posterior of T2 is smaller and there is a small pale spot on the mid posterior margin of T2. Thus, given that there is some colour variation in nearly all the species represented by multiple individuals of the same sex, we believe them to be conspecific.

Known only from the holotype female from the southerly island of Hainan. It differs from T.albilateralis which also has contiguous black markings on TT1–5 in that the whitish anterolateral areas of the tergites are distinctly smaller (Fig. 21B cf. 21A), and the fore wing vein 1cu-a is virtually interstitial.

Comments.
Known from the holotype female, two female paratypes, and a male paratype collectively from locations in Fujian, Guangxi, and Yunnan. The original description notes some variation in colour with TT1 and 2 sometimes being largely yellow and T5 sometimes largely black but does not specify whether or not these variants reflect sexual dimorphism.

This is one of two predominantly brown-yellow species that have a simple rounded, not produced, basal lobe to the claws (Chen and He 1997: fig. 324). The other known species with this unusual character is T.simulatus, thus far known only from Vietnam (Long 2014: fig. 31).

Comments.
Known only from a single male specimen from Yunnan. The holotype has a distinctively coloured metasoma, ochreous yellow with some darker medial spots but, given the sexual dimorphism in colour pattern in the boldly coloured species (T.benjamini sp. nov. and T.contrastus), it is impossible to know whether this would be useful for recognising females of the species.
Discussion
The molecular phylogenetic analysis (Fig. 4) shows that Troporhogasalboniger sp. nov. is nested within the T.contrastus clade, their barcode sequences differing by only one base pair. Hence all specimens of these two species fall into the same BIN (Ratnasingham and Hebert 2013), and they are undoubtedly closely related and presumably have speciated quite recently. Unfortunately for the new species we were only able to obtain sequences from the barcode gene and not from the other three markers. There are three reasons we recognise these as different species. Firstly, we identified three consistent differences in mesosomal sculpture, and importantly, the vertical striation in the new species at the anterior of the mesopleuron is not simply a matter of an increase in density of a feature as there is no indication of such sculpture in T.contrastus. Secondly, the difference in colouration is also not simply a matter of intensity. The available material of T.contrastus displays a small amount of colour variation, with some having the mesoscutum more orange-red and others black with piceous orange, but none show the pure blackness of T.alboniger sp. nov. The head, including mouthparts and palps, of T.contrastus are orange-yellow whereas in the new species the head is bicoloured with a sharp demarcation between the pure black upper parts and the virtually pure white malar area, mouthparts, and palps. Thirdly, there is very little variation in colour pattern in either of the two species that are represented in our collection based on multiple female specimens T.benjamini sp. nov. and T.contrastus.
Although a fairly gradual variation (especially in degree of melanisation) is not uncommon in the Braconidae, and examples are known of temperature, latitudinal (Ito et al. 2015), or host-induced colour differences, again in degree of melanisation: there are very few examples where genuine pattern polymorphism has been found (Tucker and Sharkey 2016). We are not aware of any examples involving the replacement of one colour with two quite different colours such as that seen in the difference between T.contrastus and T.alboniger sp. nov., and therefore we believe that collectively the evidence supports that these are two distinct species.
