Description. Male holotype. Length 2.4 mm, width 1.7 mm; body oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color black; head with apical ½ yellow, basal margin of yellow area sinuate ( Fig. 577 ); pronotum with anterolateral angle narrowly reddish yellow; elytron with large, irregularly oval macula medially in basal ½ ( Fig. 575 ); antenna, mouthparts, legs yellow; epipleuron dark reddish brown; abdomen brownish yellow except median portion of basal 3 ventrites brown. 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 or less; metasternal punctures as large as on mesosternum separated by less than a diameter; abdomen with punctures on ventrites 1–3 small, separated by 1 to 3 times a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons 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 slightly descending externally, wide in basal ½, as wide as pronotal hypomeron, with feeble depressions for reception of femoral apices. Prosternum slightly longer than wide, longer than short mesosternum, base arcuate medially, lateral carina slender, extended nearly to base of prosternum. Postcoxal line on ventrite 1 long, strongly angulate, extended 3/4 distance to ventrite apex ( Fig. 576 ). Apex of ventrite 5 weakly arcuate. Genitalia with long phallobase, basal lobe shorter than paramere, slender, lateral margin nearly straight to rounded apex, apex barely perceptibly emarginate; paramere weakly curved, narrow in lateral view, slightly bent before rounded apex, without marginal serrations ( Fig. 578, 579 ); sipho short, robust, slightly bent before apex ( Fig. 580 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; VENEZUELA: Tachira, Pregonero, Prensa Las Cuevas , 650m, 19– 13, VII 1989, S.&J. Peck, forest edge, ex: f.i.t., 89– 253. ( CMNH).

Remarks. Prodilis rosie is characterized by the unique elytral color pattern, a sharply angulate postcoxal line on the basal abdominal ventrite, and, to a lesser degree by the male genitalia.
