Diagnosis.

This species does not have a carinate prosternum in either male or female. The prosternal process is longitudinally slightly impressed, the lateral margins are convergent to the pointed apex. The male mesotibia is basally abruptly curved (Fig. 66). The male metafemur is moderately broad and has a distinct denticle along the ventral margin apically and another near the apex of the trochanter (Fig. 65). Unlike other species, the lateral pronotal margins are not strongly curved (Fig. 61). The male abdominal ventrite VI is unmodified. The male median lobe is deeply bifurcate with each branch narrow and apically broadly expanded and spatulate in ventral aspect (Fig. 63). In lateral aspect the median lobe is narrow and abruptly and evenly curved (Fig. 62). The basal segment of the lateral lobe is very slender and small, and the apical segment is large and broadly round (Fig. 64).

Distribution.

The species is known from Brazil and Bolivia (Fig. 103). Young (1986) mentioned a potential specimen from Panama, but this seems unlikely.
