Description. Female lectotype. Length 3.1 mm, width 2.6 mm; body oval, convex. Color reddish yellow except pronotum mostly black with anterior border, irregular area in lateral 1/4, and small, elongate, median spot yellow; elytron with basal and sutural margins dark brown, sutural border widened medially, with 4 large, dark brown spots arranged in two rows, first row in basal 1/2, second row on apical declivity ( Fig. 318 ); ventral surface with prosternum, meso- and metaventrites dark brown; abdomen brown medially, yellowish brown laterally. Head punctures small, separated by less than a diameter, each puncture as large as 2 eye facets; pronotal punctures larger than head punctures, separated by less than a diameter; elytral punctures larger than on pronotum, separated by a diameter or less; metaventral punctures 3 or 4 times as large as on pronotum, separated by a diameter medially, becoming larger and nearly contiguous toward lateral margin. Clypeus very slightly emarginate apically, nearly truncate, lateral angle broadly rounded, surface with dense, long pubescence. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, sides straight, basal and anterior angles abruptly rounded, basal margin without bordering line. Epipleuron wide, grooved, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange evenly arcuate, narrower than remainder of protibia, outer margin smooth; sponda deep, slightly wider than flange. Carinae on prosternal process pronounced, narrowly spaced apically, weakly convergent toward base, joined at basal 1/8 of prosternum, connected to prosternal base by single carina. Abdomen with primary pores laterally between ventrites 4-5 large, occupying apical 1/3 of ventrite 4, forming large, deep depression on ventrite 5; postcoxal line on basal abdominal ventrite straight in basal 1/3, extended to apical margin of ventrite at middle, rounded in apical 2/3, extended forward; ventrites 1-4 with dense, moderately long pubescence, densely punctured throughout, punctures contiguous or nearly so, coarse medially and fine laterally; 5th ventrite densely, finely punctured, apical margin weakly emarginate; 6th ventrite finely, densely punctured, apical margin weakly arcuate. Genitalia with spermathecal capsule short; bursal cap with 3 arms, median arm weak, apical strut long, slender ( Fig. 319 ).
