Description.

Male. Body covered with setae on surface. Pronotal borders, hypomeron, vertex, labrum, mandibles, the last segment of maxillary palpus and abdominal sternite with dense, short setae.

Head bent at right angle to pronotum. Anterior border of labrum slightly emarginated in middle. Oculus reniform, densely covered with setae on posterior part.

Pronotum: transverse, widest at posterior one-fourth, with the anterior part distinctly narrowed and the posterior part slightly narrowed; anterior border broadly emarginated and the emargination straight in middle, lateral borders broadly protuberant, posterior border bisinuate ( Fig. 2 : 13); anterior angles acute, posterior angles slightly obtuse, protruding; disc slightly convex, sparsely covered with setae, with short and narrow furrows.

Mesonotum slightly convex in middle of posterior part, posterior border slightly protuberant. Posterior border of metanotum straight.

Elytral sheath striped, setose. Each elytral sheath with an apophysis near base. Metathoracic wing sheath completely shrouded by elytral sheath ( Fig. 2 : 10-12).

Abdominal segments I-IX curved ventrally. The width of abdominal segments I-VII gradually narrowed posteriorly. Abdominal tergites I-III each with 2 pits near anterior border and placed on both sides of dorsomeson, the pits of tergite I obscure, those of tergites II and III distinct. Posterior border of abdominal sternite VIII distinctly emarginated in middle, each side of the emargination with a long seta. Urogomphi parallel to and distinctly separated from each other, BUL shorter than UL ( Fig. 2 : 15-16). Abdominal segment IX and urogomphi densely covered with long setae. Abdominal tergites I-VII each with a concaveness between its lateral process and lateral border in middle, lateral processes thin, nearly transparent, each with 2 large setose tubercles and 0-2 setae along outer border, without minute setose tubercle ( Fig. 2 : 17-18). Outer borders of lateral processes of abdominal tergites I-VI slightly emarginated in middle. Spiracles of abdominal tergites I-VI oval.

Gonotheca without apophysis.

Female. Unknown.
