Note. LEVI (1986:192) stated that the males and females described as C. cambara does not necessarily belong together.MCN records indicated an additional female “ paratype ” (ex-MCN 12784; same data of holotype) which should be deposited at MCZ; however this specimen is not indicated at the original description.

Diagnosis. Females ( Figs 22-27 ) of the species can be easily recognized by the shape of the epigynum, with the septum bearing two heavily sclerotized lobes ( Figs 25-27 ; see also LEVI, 1986:192, 193, figs 620, 621). Males of the species ( Figs 15-21 ) are close to C. calima Levi, 1986 and C. bolivia Levi, 1986 by the general triangular shape of the bulb, bearing a broad, coiled and long embolus ( Figs 19-21 , see also LEVI, 1986:202, 203, figs 708, 709); they can be distinguished from those of both species by the shape of the paracymbial apophysis bearing a long and concave lower portion ( Figs 18-21 ).
