Redescription. Body tiny, brown to pitchy. Head and pronotum much darker than other parts of body. Abdominal tergites II–VI each with posterior segmental membranes sometimes exposed, so in dorsal view one can see 5 obvious stripes on abdomen. Length [average] male, 2.8 mm; female, 2.6 mm.

Male. Head ( Fig. 12A) sub-pentagonal, widest at eyes. Disc punctate and rugose posteriorly, not pubescent. Clypeus flat, slightly protruding, almost 1/4 head length, surface impunctate and coriaceous; anterior margin truncate or shallowly emarginate in middle. Epistomal suture with lateral portions incurved and running posteriorly. Vertex weakly convex, definitely distinguished from neck; with mid-longitudinal suture distinct. Eyes convex, with coarse facets. Temples obsolete. Occipital suture broadly curved in dorsal view; nuchal ridge present and visible in middle, dorsal basal ridge present.

Mandible ( Fig. 12C) slender and slightly curved; two denticles on inner edge. Antenna (type I) almost equal to head and pronotum together, with apical antennomere longer than preceding one.

Pronotum transverse, broadest at near anterior 1/3, wider than head. Disc punctate and 3-sulcate (as Fig. 1H); two paralateral depressions shallow, weakly punctate and striate; lateral margin even and broadly rounded, posterolateral angles rounded. Elytra punctate and rugose, with lateral longitudinal ridge feeble.

Abdomen coriaceous and covered with dense fine hairs, broadest at segment V. Sternite VII ( Fig. 12E) with posterior margin almost straight bearing two obsolete teeth near middle. Sternite VIII ( Fig. 12F) with subbasal ridge straight; posterior margin broad with two deeply V-shaped ruptures near middle, forming broad and rectangular median plate, base of which depressed lightly, posterior margin truncate. Tergite X ( Fig. 12H) longer than wide, posterior margin bi-emarginate, with two lines of setae on haired posterior part.

Aedeagus ( Figs. 12K–N). Median lobe sub-oblong in ventral view, almost parallel-sided, widest at middle; with internal sac elongated, ovoid, membranous, and containing smaller ovate sac in center; apical orifice almost as large as median lobe width; apico-medial hook short and laminar, stuck on ventral surface of median lobe, with apex bifurcated; articular joints connecting median lobe with parameres large and between them with lingulate piece; dorsal membranous area covering all dorsum. Paramere horn-like, with small process at middle of apical arm and furnished with seta, with highlighted zone nearby; apex upcurved and sharply pointed, with another short process nearby, at basal 1/3 of apical arm furnished with small process medially and upward directed, with shallow furrow on basal arm.

Female. Head ( Fig. 12B) similar to male, but more triangular than sub-pentagonal; vertex a little more convex; eyes convex and covering most of lateral plate of head; temples extremely obsolete. Mandible ( Fig. 12D) same as male, but in some cases a little larger and robuster.

Abdominal sternite VII with posterior margin straight and not modified. Sternite VIII ( Fig. 12G) with posterior margin broadly rounded. Tergite X ( Fig. 12I) scutiform, posterior margin bi-emarginate like male.

Spermatheca ( Fig. 12J) ʋ- shaped, bent twice, and a little inflated at base.

Distribution. China (Anhui, Beijing, Chongqing, Fujian, Guangxi, Guizhou, Heilongjiang, Hong Kong, Hubei, Jiangsu, Shaanxi, Shanghai, Taiwan, Zhejiang); Japan; Vietnam; Thailand; Malaysia; Indonesia; Sri Lanka; Europe.
