Description. Length of males 6.5–7.5 mm, females 8.5–9.0 mm.
Female genitalia. Abdominal sternite VII (Fig. 44), in ventral view, slightly broader than long; posterior margin forming rounded median lobe; lateral margins approximately parallel; surface with few setae mostly on anterior half. Internal sternite VIII without sclerites. Pygofer (Fig. 45), in lateral view, well produced, longer than tall; posterior margin rounded; surface with macrosetae on posterior portion and extending anteriorly along ventral margin, attaining basal margin. Valvifers I (Fig. 46), in lateral view, nearly fanshaped, posterodorsal margin nearly angulate and posteroventral margin broadly rounded. Valvifers II (Fig. 54) with small group of clustered setae near articulation point. Valvulae I, in ventral view (Figs 93 and 94), forming broad concavity (BC) between anterior margins, with membranous area in concavity; in lateral view (Figs 47–49), with dorsal and ventral margins nearly rectilinear behind basal curvature, but ventral margin distinctly curved dorsally near apex; dorsal sculptured area extending from basal curvature to apex, broader on median portion, formed mostly by scale-like processes arranged in oblique lines; ventral sculptured area with scale-like processes arranged in lines on apical portion; ventral interlocking device distinct on basal 1/3 of shaft; apex of shaft acute; dorsal margin forming small denticles on apical portion of shaft. Valvulae II (Figs 50–53), in lateral view, with dorsal margin approximately rectilinear behind basal curvature, ventral margin curved dorsally near apex; apical portion with dorsal margin slightly concave; apex subacute; preapical prominence indistinct; shaft bearing approximately 35 teeth from basal portion to apex; first tooth large, triangular and with long anterior ascending portion, followed by about 10 well produced subtriangular teeth, the latter followed by rectangular ones; each tooth with denticles; apex of shaft with dentate dorsal margin longer than ventral margin; ducts extending toward teeth and toward apical shaft portion. Gonoplacs (Fig. 55), in lateral view, with basal half narrow and apical half moderately expanded, apex subacute, surface with few setae on apical portion.
Distribution. China (Guangdong, Hainan, Guizhou); Vietnam.
Remarks. Young (1986) provided descriptions of the coloration, external features and genitalia of female specimens, but the female genitalia features were briefly described and only abdominal sternite VII was illustrated. Li & Wang (1992) and Yang & Li (1999) provided descriptions of the male genitalia. We provided herein detailed descriptions and illustrations of the female genitalia.
