Diagnosis
This species lacks a carinate and spinous prosternum in either sex. The prosternal process is flat, the lateral margins are slightly convergent to the pointed apex. The male mesotibia is unmodified. The male metafemur and metatrochanter are unmodified (Fig. 91). The male abdominal ventrite VI is deeply indented laterally and apically impressed. The male median lobe in lateral aspect is slender and only slightly curved through most of its length to the apex which is abruptly curved and sharply pointed with a subapical tooth (Fig. 88). In ventral aspect the median lobe is deeply bifid with irregular lateral rami which terminate apically in laterally directed hooks (Fig. 89). The lateral lobe in lateral aspect has a small basal portion with the apical portion moderately large, and apically with a broad dorsally directed rounded lobe (Fig. 90). This is a small species, only about 2 mm in length, with maculate elytra (Fig. 87).
Distribution
Known from Venezuela, Guyana and Brazil (Fig. 103).
