Figs 3–4 , 25 , 41

C. bertae Pérez­Miles, 1998: 99 , figs 21–24. Holotype male, IBSP 4950, from Rio Branco, Acre, Brazil, 22 October 1995, S. Braga, examined. Female unknown.

Diagnosis: The male differs from all other species, except C. versicolor and C. sellatus , by not having a striped dorsal abdominal pattern ( Fig. 41 ). It differs from C. versicolor by having a retrolateral field of spiniform hairs on palpal tibia and from C. sellatus by the short paraembolic apophysis (Figs 3,4).

Distribution: known only from type locality, Rio Branco, State of Acre, Brazil ( Fig. 56 ).
