Opisthacidius picturatus Lent & Wygodzinsky, 1956

This species was previously known only from Venezuela (Aragua) ( Lent & Wygodzinsky 1956). Because females were hitherto unknown, the most remarkable aspects of the female as compared with the male are here described. The female specimen examined is very similar to the male, but bigger. Total length: 27 mm; maximum width at pronotum: 7 mm; maximum width at abdomen: 7.5 mm. The coloration of the neck was not mentioned in the original description for the male specimens but in this female, the neck has a central black stripe, and 1+1 lateral orange ones. The pronotum has a similar color pattern as in the male, but with the 1+1 “U” shaped markings connected to the longitudinal central one ( Fig. 39 ). The lateral margins of the scutellum are orange, rather than dark. The pleura are dark red instead of orange as in male. The pro­ and mesopleura lack this dark red color posteriorly. The dark spot of the inner part of the corium is continued as a line to the wing base. The ventral abdominal carina barely extends to segment VI. The specimen listed below is a new record from Colombia.

Material examined: COLOMBIA, 1Ψ, Valle del Cauca, Bajo Calima (bosque), 70 m, XII­1960, L. Gallego [ MEFLG].
