Diagnosis
This species does not have a carinate prosternum in either male or female. The prosternal process is flat, the lateral margins are slightly convergent to the apically rounded apex. The male mesotibia is unmodified. The male metafemur and metatrochanter are not noticeably modified (Fig. 45). The male abdominal ventrite VI is apically and laterally somewhat impressed. The male median lobe is basally broad, but apically very slender with an apical broad, denticulate expansion (Fig. 42). In ventral aspect it is deeply bifid with each branch slender and apically irregular, and sharply angulate (Fig. 43). The basal segment of the lateral lobe is moderately small and elongate triangular. The apical segment is broad and extremely irregular with a prominent apical, finger-like lobe (Fig. 44). Specimens are elongate oval with the elytra longitudinally vittate (Fig. 41);
Distribution
Known from lowland South America from northern Venezuela to southeastern Brazil (Fig. 102).
