- Bidessodes (Bidessodes) acharistus Young, 1986:217; Biström, 1988:7; Nilsson, 2016:98.
Diagnosis
This species does not have a carinate prosternum in either male or female. The prosternal process is flat and parallel-sided with the apex broadly acuminate. The male mesotibia is basally bent. The male metatrochanter and metafemur are broad, the metafemur is apically truncate with a distinct denticle along the ventral margin near the apex of the metatrochanter (Fig. 25). The male abdominal ventrite VI is apically slightly impressed medially. The male median lobe in lateral aspect is moderately broad basally with an elongate, broadly curved, slender apical portion that is medially somewhat expanded (Fig. 22). In ventral aspect the median lobe is slender and deeply bifid with each ramus sinuate and subapically expanded and ending in a single pointed process (Fig. 23). The basal segment of the lateral lobe is short and oblique (Fig. 24). The apical segment is very broad and has a broad dorsal expansion apically (Fig. 24). Specimens are relatively immaculate (Fig. 21).
Distribution
Known from few localities in Brazil and Bolivia (Fig. 99).
