Body brown to dark testaceous. Head pitchy, pronotum brown with dark posterior and lateral margins. Abdomen brownish. Length [average] male, 5.0 mm; female, 4.7 mm . Male . Head ( Fig. 5A ) far broader than long, widest at eyes. Disc sparsely punctate, less pubescent. Clypeus trapezoidal and not protruding, almost 1/3 head length, weakly depressed in anterior part (lower than anterior margin), surface impunctate and coriaceous; anterior margin truncate. Supra-antennal ridges moderately elevated upward. Epistomal suture, lateral portions running posterolaterally curved medially after posterior 1/3. Vertex almost flat, definitely distinguished from neck by middle portion of occipital suture; with mid-longitudinal suture distinct. Eyes with coarse facets, strongly convex and protruding laterally, twice or more longer than temples. Temples broadly rounded at posterolateral angles. Occipital suture arcuate in dorsal view; nuchal ridge present and visible in middle, dorsal basal ridge present. Mandible ( Fig. 5C ) stout, slightly curved; two denticles on inner edge near middle. Antenna ( type I) a little shorter than or equal to head and pronotum together, with apical antennomere longer than preceding one. Pronotum transverse, broadest at near anterior 1/3, slightly wider than or equal to head. Disc 3-sulcate (as Fig. 1H ), but with two paramedial sulci and two paralateral depressions shallow; lateral margin even in front, crenulate behind, posterolateral angles rounded. Elytra ( Fig. 1J ) punctate and rugose, and with lateral longitudinal ridge present. Abdomen coriaceous and pubescent, broadest at segment IV or V. Sternite VII ( Fig. 5E ) with posterior margin shortly produced in middle and weakly emarginate at apex. Sternite VIII ( Fig. 5F ) broad, with subbasal ridge continuous in middle, with two deeply V-shaped ruptures near middle, forming large and subrectangular median plate, apical margin of median plate straight but a little produced in middle, in center of median plate with small tubercle, with seta at each posterolateral corner, with mid-longitudinal internal ridge on inside surface. Tergite X ( Fig. 5H ) longer than wide, posterior margin truncate with a little notch in middle, posterior margin with two lines of setae on haired posterior part. Aedeagus ( Figs. 5K–M ). Median lobe oblong-ovoid, widest at middle; with membranous structures inside apical part of median lobe; apical orifice large; apico-medial hook flattened C-shaped in lateral view and bent at near middle, with apical tip pointed, basal process well developed and with round tip; dorsal membranous area not covering all dorsum but across length of median lobe. Paramere arm-like, with seta on apical 1/3 of apical arm and with highlighted zone nearby; apex pointed; with shallow furrow on basal arm. Female . Head ( Fig. 5B ) smaller than male. Eyes convex and protruding laterally beyond temples, temples almost invisible in lateral view. Mandible ( Fig. 5D ) as long as in male but slenderer and shaper at apex. FIGURE 5.

Scales: J = 0.1 mm; rest, 0.3 mm. Abdominal sternite VII with posterior margin straight and not modified. Posterior margin of sternite VIII ( Fig. 5G ) broadly rounded but moderately produced in middle and furnished with small tooth on each side, a little processed between middle process and each of teeth. Tergite X ( Fig. 5I ) scutiform, with posterior margin truncate. Spermatheca ( Fig. 5J ) slim and 3-bent. Distribution. China ( Gansu , Guangxi , Guizhou , Hong Kong , Hubei, Jiangsu, Jiangxi, Liaoning, Shanghai, Sichuan, Taiwan , Zhejiang); South Korea ; Japan ; Vietnam ; Laos ; Myanmar ; Thailand ; Malaysia ; Singapore ; Bangladesh ; Sri Lanka ; Nepal ; Pakistan ; India .
