Description. Male holotype. Length 2.4 mm, width 1.6 mm; body oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny without trace of microsculpture. Color black (Fig. 393); head black with yellow macula on anterior 1/3 of frons, base of macula partially divided by 2 short brownish black vittae (Fig. 395); pronotum black except reflexed fore angle reddish yellow; elytron reddish yellow with sutural margin broadly black from base to apex, black area tapered from base to apex, lateral margin narrowly black from basal 1/3 to apex; antenna, epipleuron, legs yellow; mouthparts yellow except apical maxillary palpomere brown; ventral surface reddish yellow; abdomen brownish yellow. Head punctures small, separated by a diameter or less; pronotal punctures slightly larger than on head, separated by less than twice a diameter; elytral punctures larger than on pronotum, separated by less than twice a diameter; prosternal punctures large, separated by a diameter or less; mesosternal punctures large, separated by less than a diameter; metasternal punctures large apically and laterally, separated by less than a diameter, medial punctures smaller, widely spaced; abdomen with punctures on ventrites 1–3 smaller than on metasternum, separated by 1 to 3 times a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with sides of frons slightly divergent from vertex to clypeus, slightly wider than eye measured at vertex; eye canthus short; apical maxillary palpomere short, weakly widened from base to apex. Pronotum widest before middle, reflexed lateral margin narrow, equal in width from base to apex. Epipleuron flat, as wide as pronotal hypomeron. Prosternum about as long as wide, longer than mesosternum, apical margin weakly arcuate; lateral carina slender, extended to apex of coxa. Postcoxal line on ventrite 1 long, rounded, extended slightly, almost to ventrite apex (Fig. 394). Apex of ventrite 5 arcuate. Genitalia with basal lobe longer than paramere, slender, sides nearly parallel to deeply emarginate apex; paramere slightly curved, wide, widest at middle, narrowed in apical ½ to abruptly rounded apex, without marginal serrations (Fig. 396, 397); sipho short, robust (Fig. 398).

Female. Similar to male except head black. Spermathecal capsule with ramus widened, remainder of capsule narrow, cornu apically rounded (Fig. 399).

Variation. Length 2.4–2.6 mm, width 1.6–2.0 mm. Ventral surface black in the Peruvian paratype.
