Description. Male holotype. Length 2.3 mm, width 1.7 mm; body oval, elongate, elytron with side slightly rounded, nearly straight, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny, without trace of microsculpture. Color dark brown; head with base of frons and vertex black, remainder of head yellow ( Fig. 510 ); pronotum with lateral 1/5 yellow; elytron dark brown with bluish tint, reflexed lateral margin reddish brown ( Fig. 508 ); antenna, legs yellow; mouthparts yellow except apical maxillary palpomere brown; ventral surface including epipleuron reddish brown; abdomen with basal 4 ventrites brown, ventrites 2, 3 laterally yellow, 5th ventrite yellow. Head punctures small, separated by a diameter or less; pronotal punctures larger than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by a diameter or less; prosternal, mesosternal punctures large, separated by a diameter; metasternal punctures as large as mesosternal punctures laterally, smaller, more scattered medially; abdomen with punctures on ventrites 1–3 as large as on metasternum, separated by less than a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons weakly widened from vertex to clypeus, 1.4 times width of eye measured at vertex; eye canthus short; apical maxillary palpomere short, 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. Prosternum longer than wide, longer than mesosternum, base truncate, lateral carina slender, extended anterior to apex of coxa. Postcoxal line on ventrite 1 long, rounded, extended 3/4 distance to ventrite apex ( Fig. 509 ). Apex of ventrite 5 arcuate. Genitalia with basal lobe slightly longer than paramere, wide, widest in apical 1/4, lateral margin curved from base to apex, apex not emarginate; paramere weakly curved, slender, equal in width to rounded apex, without marginal serrations ( Fig. 511, 512 ); sipho robust, long ( Fig. 513 ).
