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).

Description.

Male. Well described, e. g. by Tanasevitch (2014b).

Female (one of females from Xishuangbanna). Total length: 2.13. Carapace 0.75 long, 0.63 wide, unmodified, brownish yellow with dark outer margin (Fig. 3D). Sternum 0.41 long, 0.50 wide. Clypeus 0.13 high. Chelicerae promargin with 6 teeth, retromargin with 5 teeth. Eye sizes and interdistances: AME 0.06, ALE 0.08, PME 0.08, PLE 0.08, AME-AME/AME 0.33, PME-PME/PME 0.63, AME-ALE/ALE 0.63, PME-PLE/PLE 0.63, coxae IV separated by 1.43 times their width. Length of legs: I 3.70 (1.04, 0.24, 0.96, 0.88, 0.58), II 3.85 (0.96, 0.25, 1.06, 0.92, 0.66), III 2.95 (0.83, 0.23, 0.70, 0.72, 0.47), IV 3.72 (1.00, 0.20, 1.00, 0.96, 0.56). Leg formula: II-IV-I-III. TmI 0.38, TmIV 0.31. Tibial spine formula: 2-2-1-1. Abdomen pale, with dark green patches. Epigyne: lump-shaped (Fig. 3A), copulatory openings ambiguous; copulatory ducts long and twirled (Figs 3C, 4D); spermathecae widely separated (Fig. 3C).
