ARGUMENTATION

The examination of the holotype of C. minima revealed its synonymy with C. petri . The genitalia of this specimen are figured for the first time ( Fig. 3 C-D). Both the latero-dorsal and latero-ventral lobes of tergum X have their distal extremities more sclerotized than their basal parts, which are thinner and difficult to distinguish from each other. Gibbs (1973) already noted the relationship of C. petri to C. intexta , C. cognata and C. lufirae . Besides the differences in tergum X, C. minima differs from other species of the group in the absence of a process on the inner face of the inferior appendage and the reticulated appearance of the prolongations of the phallic apparatus.
