Diagnosis This species can be separated from all other species of Birdantis by the following combination of characters: (1) frons yellow-brown, with three black-brown lines limited dorsally to level of middle of eyes, and with the two lateral ones extending on clypeus ( Figs 7D , 8D ) (2) bulge between frons and vertex dark brown and vertex yellow-brown ( Figs 7B , 8B ) (3) tegmina opaque on basal half and infuscate on distal half ( Figs 7A , 8A ) (4) hind wings largely smoky, with a basal reddish brown marking ( Figs 7A , 8A ) (5) abdomen mostly dark red dorsally ( Figs 7A , 8A ) and yellow-brown ventrally ( Figs 7C , 8C ) (6) anterior margin of frons in dorsal view rounded and strongly protruding ( Figs 7B , 8B ) Material examined Lectotype INDONESIA : ♀ (designated to improve nomenclatural stability in the group, Fig. 7 ), Buru Island , 3°23′55″ S , 126°38′54″ E [Buru 1921, Station: 1 leg.

Supplementary description Male genitalia Pygofer higher than long, about 2.0 times as high as maximum length, longer ventrally and abruptly narrowing on dorsal ½ in lateral view; dorsal margin of pygofer horizontal in lateral view ( Fig. 9A ). Anal tube elongate, about 1.5 times as long as maximum breadth, nearly straight with ventral margin sligtly curved in lateral view; progressively broadening from base towards ¾ of length in dorsal view, then with lateral margins converging; apical margin strongly, roundly emarginate in dorsal view, acutely rounded in lateral view ( Fig. 9A–B ). Gonostyli slightly elongate in lateral view, with ventral margin slightly concave and posterior margin broadly rounded; anterodorsal margin slightly emarginate after lateral process; lateral process laminate, curved laterally and apically pointed, with apical point directed lateroventrally ( Fig. 9A–B ). Aedeagus mostly membranous ( Fig. 9C–F ). Distribution Buru, Seram, Ambon and Boano Islands ( Fig. 3 ).
