Description. Male. Body dark-brown, with sparse, minute pubescence in most areas. Head rectangular, vertex moderately convex, with pair of distinct vertexal foveae; antennal tubercles low; frons flattened, subantennal transverse sulcus complete, with shallow vertexal sulcus merging with subantennal transverse sulcus and connecting foveae; each eye composed of about 30 facets; antennae relatively thin, antennomeres III‒VIII elongate, IX as long as wide, X transverse, XI largest, widest at middle; median gular carina shallow, with two separated nude foveae. Pronotum with indistinct median antebasal fovea and complete basal impression. Each elytron with two shallow foveae at base. Protrochanters protuberant at ventral margin (Fig. 14 R). Abdomen slightly narrowed at base; tergite IV (first visible tergite) with narrow basal sulcus; discal carinae relatively long, close, extending to apical one-third of tergal length; short marginal carinae extending to one-seventh of tergal length. Aedeagus (Fig. 12 A–C) 0.27 mm in length, relatively stout, parameres distinctly exceeding apex of median lobe, rounded apically, each with two long apical setae; endophallus symmetric, comprised with three sclerites, with lateral two widely separated at base, and numerous weakly-sclerotized setae-like structures.
Female (Fig. 5 A). Similar to male in general appearance; protrochanters simple; each eye composed of about 30 facets.
