ABSTRACT
The genus Troporhogas Cameron, 1905 from the Indo-Malayan region is reviewed. Six new species, Troporhogasalboniger Quicke, Loncle & Butcher, sp. nov., T.benjamini Quicke, Loncle & Butcher, sp. nov., T.hugoolseni Quicke, Loncle & Butcher, sp. nov., T.rafaelnadali Quicke, Loncle & Butcher, sp. nov., and T.rogerfedereri Quicke, Loncle & Butcher, sp. nov. from Thailand, and T.anamikae Ranjith, sp. nov. from India are described and illustrated photographically, bringing the total number of species of the genus known from the Indo-Malayan Region to 19. Troporhogas is recorded for the first time from India. A key is included to differentiate Troporhogas species. A four-gene ML tree based on COI, Cytb, 16S and 28S is reconstructed, representing the six new species. Troporhogascontrastus Long, 2014, originally described from Vietnam, is recorded from Thailand for the first time. The holotypes of the type species, Troporhogastricolor Cameron, 1905 and that of its junior synonym Iporhogas are illustrated, and photographs are presented of all the species known only from China and Sri Lanka. Sexual colour dimorphism of males of several species is described for the first time. Drawings summarising the different patterns of black marks on the metasoma that aid species recognition are presented.
ABSTRACT
Charmon thailandensis sp. nov. from Thailand is described and illustrated based on a female specimen from Doi Phu Kha National Park, Nan Province, Thailand. The new species is distinguished from apparently closely-related species of Charmon Haliday, 1833, based on both morphology and DNA sequence (barcode) data. Morphologically it appears to be near to C. extensor (L., 1758) but DNA data suggest it is quite basal with respect to all the other sequenced species. A checklist of the 10 known species of Charmon with their known distributions is provided. The possibility that C. extensor might represent a complex of more than one species is briefly discussed.
