Diagnosis.

This genus was described from Laos by Tanasevitch (2014b), including two species: Asiagone signifera Tanasevitch, 2014 and Asiagone perforata Tanasevitch, 2014. The male is diagnosed as Asiagone perforata by the long, whip-like embolus equipped with a leaf-shaped process at the approximately midpoint (Fig. 1D), horn-shaped distal apophysis of convector (Fig. 2A), and convector’s membraniform extension that covers most part of bulb in prolateral view (Figs 1A, 4A). The female is described for the first time; it possesses a distinct lump-shaped epigyne (Fig. 3A), in which ventral and dorsal figs are fused and the margin of figs is indistinct (Fig. 3 B–C).
