Male (Fig. 6 A – C). Antennomere number on right antennae 43 and on left antennae 44; third antennomere longer than second one; Ant 3 L / Ant 2 L more than 2.00. Compound eyes well-developed, tinged with black. Maxillary palpomere IV very slightly shorter than maxillary palpomere III. Each cervical sclerite with eight macrosetae. Pronotum longer than wide; square-shaped with convex posterior edge; transverse sulcus at anterior margin convex. Cerci composed of ten cercomeres.
Genitalia (Fig. 6 D – G). Subgenital plate with long distal process. Right coxopodite with narrow part apically, which is longer than that of left coxopodite; inner margin of right coxopodite weakly concave in proximal half in ventral view; dorsal margin of right coxopodite bearing flatten projection, which is usually hidden between copulatory sclerite and subgenital plate; right stylus long. Left coxopodite with short narrow part apically; inner margin sloping with very weak undulation; right stylus long. Right phallomere weakly sclerotized in entire right surface. Left phallomere mainly membrane, with belt-shaped sclerotized zone running dorsoventrally; distal surface of sclerotized zone without distinct bump. Principal copulatory process well-sclerotized, apically with two wing-like projections.
