DIAGNOSIS: Males resemble those of C. bondi in having a straight retrolateral tibial apophysis (fig. 475), but have a short embolar apophysis and a small median apophysis (fig. 474); females can easily be recognized by the wide epigynal septum (fig. 476).

Retrolateral tibial apophysis straight, bifid at tip (fig. 475); embolar apophysis short, hardly protruding from bulb, tegular apophysis without apical projection, median apophysis short, with folded tip (fig. 474).

FEMALE: Total length 8.0. Coloration as in C. keira except abdominal dorsum without transverse white stripe. Leg spination: femora: II p0­0­0; III p0­1­1, r0­0­0; IV r0­0­0; tibiae: III p0­1­1, r0­1­1; IV p0­0­1; metatarsi III, IV p0­1­1, r0­1­1. Epigynum triangular, posterior half with wide median septum (fig. 476); spermathecae extending anterior of origin of translucent ducts (fig. 477).
