Description. Male holotype. Length 1.9 mm, width 1.4 mm; body oval, slightly elongate, elytron with side slightly rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface shiny except elytron with trace of microsculpture. Color black; head with base of frons and vertex brown, remainder of head yellow ( Fig. 493 ); pronotum with lateral 1/4 paler brown than disc; elytron brownish yellow bordered with brown ( Fig. 491 ); scutellum black; antenna, mouthparts yellow; legs brownish yellow; epipleuron reddish brown; abdomen brownish yellow. Head punctures small, separated by a diameter or less; pronotal punctures slightly larger than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; prosternal punctures large, sparse, separated by 1 to 3 times a diameter; mesosternal punctures as large as on prosternum, separated by less than 3 times a diameter; metasternal punctures smaller than on mesosternum, separated by less than 3 times a diameter; abdomen with punctures on ventrites 1–3 smaller than on metasternum, separated by less than twice a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons not widened from vertex to clypeus, sides parallel, slightly wider than eye measured at vertex; eye canthus short; apical maxillary palpomere short, weakly widened from base to apex. Pronotum widest at middle, reflexed lateral margin wide, equal in width from base to apex. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron, with feeble depressions for reception of femoral apices. Postcoxal line on ventrite 1 long, angulate, extended 4/5 distance to ventrite apex ( Fig. 492 ). Apex of ventrite 5 strongly arcuate. Genitalia with basal lobe longer than paramere, wide, spoon shaped, widest anterior to middle, lateral margin curved from base to abruptly rounded apex, apex not emarginate; paramere weakly curved, nearly straight, slender, nearly equal in width to rounded apex, without marginal serrations ( Fig. 494, 495 ); sipho robust, apex lost ( Fig. 496 ).
