Description. Male holotype. Length 2.5 mm, width 2.0 mm; body oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color greenish black; head with vertex and base of frons black, remainder of frons yellow (Fig. 335); pronotum black, lateral 1/8 yellow; elytra with reddish brown border (Fig. 333); antenna, mouthparts, legs yellow; epipleuron dark reddish brown. Head punctures small, separated by a diameter or less; pronotal punctures as large as on head, separated by less than twice diameter; elytral punctures larger than on pronotum, separated by less than twice a diameter; prosternal, mesosternal punctures larger than on elytron, separated by a diameter or less; metasternal punctures along anterior and lateral borders as large as on mesosternum, punctures on remaining surface as large as on mesosternum, separated by less than 3 times a diameter; abdomen with punctures on ventrites 1–3 smaller than on metasternum, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons widened from vertex to clypeus, nearly twice as wide as eye measured at vertex; eye canthus short; apical maxillary palpomere short, widened from base to apex. Pronotum widest at middle, reflexed lateral margin narrow, equal in width from base to apex. Epipleuron slightly descending externally, wide in basal ½, as wide as pronotal hypomeron. Prosternum slightly longer than wide, longer than mesosternum, apical margin truncate, lateral carina slender, short, extended slightly anterior to coxa. Postcoxal line on ventrite 1 long, rounded, extended 3/4 distance to apical margin of ventrite (Fig. 334). Apex of ventrite 5 truncate. Genitalia with basal lobe longer than paramere, narrowed from base to emarginate apex; paramere weakly curved, slender, widest at base then narrowed to slender, rounded apex, without marginal serrations (Fig. 326, 327); sipho long, slender, abruptly bent at apical 1/8, filamentous (Fig. 328).

Female. Similar to male except head black with apical ½ of frons yellow, female genitalia with bursal cap widely oval, with 2 arms, apical strut long, wide at base, narrowed to acute apex, spermathecal capsule lost.

Variation. Length 2.0– 2.7 mm, width 1.6–2.3 mm.

Type material. Holotype male; BRAZIL: Fry, Rio Jan. (Rio de Janeiro), Fry Coll. 1905.100. (BMNH). Paratypes; 15, same data as holotype. (BMNH).

Remarks. This mostly black species is distinguished by the broadly pale lateral pronotal margin, greenish black elytra, and structure of the male genitalia.
