Diagnosis.

This species lacks a carinate and spinous prosternum in males and females. The terminal visible abdominal ventrite is broadly impressed apically. The male mesofemur is apically somewhat swollen. The male mesotibia is basally bent. The male metatibia and metatrochanter are relatively unmodified (Fig. 96). The male median lobe in lateral aspect is evenly curved, somewhat expanded medially and apically narrowly rounded (Fig. 93). In ventral aspect the median lobe is narrow and apically simple with short setae (Fig. 94). The lateral lobe in lateral aspect has the basal segment short and irregularly sinuate, the apical portion is extremely large, elongate subtriangular and sinuate with the apex sharply pointed (Fig. 95).

Distribution.

This species is only known from Mato Grosso, Brazil (Fig. 103).
