Scutum black, posteriorly blackish brown, paler along transverse suture, notopleural line and lines connecting ipsilateral dorsocentral setae; scutellum blackish brown, paler marginally (Pl. 5C). Hindleg tarsomere I with 1 black, apically blunt, stout spine at outer apex on underside. Tenth sternite longer than wide, distally bilobed, with deep, somewhat U-shaped, median notch on dorsal margin (Fig. 46 D). Hypandrium longer than twice of width (Fig. 46 E).

Male terminalia (Fig. 46 A −F): Epandrium pubescent in patches on posterior portion of dorsal 2/3, with ca. 13 long setae on ventrally half and with ca. 15 shorter setae on caudoventral portion. Surstylus with 1 thick seta in addition to 1 stout, upturned prensiseta above caudodorsal corner, 7 prensisetae along distal margin and 1 seta at ventral apex. Cercus slightly pubescent on anteromedial portion, with ca. 29 long setae. Hypandrium nearly parallel-sided, roundish on anterior margin. Gonopod narrow, protruded ventrad in lateral view. Paramere smooth dorsal and ventral margins, with 5 sensilla: distalmost one distantly located from others, but proximalmost two very close to each other. Aedeagal basal process about 1/2 length of paramere; aedeagal apodeme entirely thickened in lateral view.
