Coryptilus Gibson, 1995: 185–188 . Type species: Coryptilus indicus Gibson.

Key to females 1 of Coryptilus

1. Fore wing reduced in size, about 4.5× as long as broad and narrow-ovoidal with subparallel margins; basal cell hyaline behind about apical half of submarginal vein (Figs 39, 53). Pronotum with pronotal collar long, about 0.4× as long as broad (Fig. 33) and collar with sparse, white, erect setae in contrast with dense, black, erect setae on neck (Figs 36, 47). Acropleuron with only anterodorsal and posterodorsal regions reticulate, central and ventral regions shiny, alutaceous (Figs 42, 49). Metasoma shiny, mostly coriaceous (Figs 41, 51). Mesofemur posteroventrally with a couple of long, erect, and slightly lanceolate setae (Fig. 43) but metafemur without a line of long differentiated setae (Fig. 44). Mesoscutum dark brown to black, with metallic green lusters dorsally (Figs 32, 33, 50).................................. Coryptilus longicervix Kawano & Fusu sp. nov.

- Fore wing reduced in size or not but if so then wing at most about 3× as long as broad and rhomboidal, conspicuously broadened towards apex; basal cell narrowly hyaline only behind apical quarter of submarginal vein (Figs 12, 22, 30). Pronotum with pronotal collar short, about 0.2× as long as broad (Figs 4, 15, 26), and both neck and collar covered in black, erect setae (Figs 4, 26). Acropleuron entirely coarsely reticulate, though mesally cells gradually smaller (Figs 14, 23). Metasoma dull, mostly reticulate (Figs 6–8). Both meso- and metafemur posteroventrally with a line of long, erect, conspicuously lanceolate setae (Figs 9, 10, 28, 29). Mesoscutum sometimes orange to brown, almost non-metallic (Figs 16, 26)...................... 2

2. Mesosoma orange, almost non-metallic (Fig. 16) or if brown (Fig. 24) then with only limited metallic luster. Metasoma dorsally with all tergites reticulate (Fig. 27). Fore wing reduced in size, extended to about apex of Gt5, with incurved posteroapical margin and prominent posterior angle (Figs 22, 30)..................................... Coryptilus indicus Gibson

- Mesosoma dark brown, with metallic green to bluish-green lusters (Fig. 1). Metasoma with Gt3 and sometimes Gt4 imbricatealutaceous dorsally, though rest of tergites reticulate (Figs 6–8). Fore wing either not reduced in size, extended to near apex of gaster (Figs 1, 12), or if similarly reduced as above then with straight posteroapical margin and without conspicuously prominent posterior angle (Fig. 13)................................................
