Description. Male holotype. Length 3.0 mm, width 2.6 mm; body rounded, elytron with side rounded, wider than pronotal base, widest before middle of elytra. Dorsal surface shiny except elytron slightly rugose and with fine microsculpture; elytral pilosity curly. Color greenish black ( Fig. 474 ); head yellow except base of frons and vertex black, anterior margin of black area protruding medially ( Fig. 476 ); pronotum black except anterolateral angle yellow; narrow elytral margin brown in apical half; antenna, mouthparts, legs yellow; venter black; abdomen yellow. Head punctures small, separated by less than twice a diameter; pronotal punctures as large as on head, separated by a less than 3 times a diameter; elytral punctures small, slightly larger than on pronotum, separated by less than 3 times a diameter; prosternal punctures absent, surface finely rugose along lateral margin; mesosternal punctures large, separated by less than twice a diameter; metasternal punctures large, separated by less than a diameter apically and laterally, median punctures smaller, separated 1 to 3 times a diameter; abdomen with punctures on ventrites 1 to 3 small, separated by less than twice a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons narrow, widened from vertex to clypeus, about 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, nearly flat, as wide as pronotal hypomeron. Prosternum slightly longer than wide, about as long as mesosternum, base arcuate, lateral carina slender, extended to apex of procoxa, small, central spot of yellow setae present. Postcoxal line on ventrite 1 long, slightly angulate, extended beyond midpoint of ventrite ( Fig. 475 ). Apex of ventrite 5 slightly emarginate. Genitalia with basal lobe longer than paramere, slender, sides weakly narrowed from base to emarginate apex; paramere slender, curved, apex rounded, apically pointed ( Fig. 477, 478 ); sipho short, slender, slightly sinuate in apical 1/3 ( Fig. 479 ).

Female. Spermathecal capsule short, wide, narrowed from base to abruptly rounded apex of cornu.

Variation. Length 3.0– 3.3 mm, width 2.6–2.7 mm.

Type material. Holotype male; BRAZIL: S. José PINHAIS – PR, Ser. Mar Br277 Km 54, Brasil, 15. IX. 1986, Lev. ent. PROFAUPAR, MALAISE. ( DZUP) . Paratypes; 4, 3, Colegio M. Alvarenga, S.
