| Diagnosis | Diagnosis (genus): Generally small and slender species with the anterior trunk dorsoventrally compressed, rounded at midbody, and vertically ovate posterior to the cloacal region (normally at or posterior to autotomy site). Headroundedor variablypointed,usually horizontallyoval.Rostralalwaysdiscrete,but (except for C. williamsi in which in broad contact with the prefrontals), small, and visible only as a tiny triangle in dorsal view. All forms with a band of enlarged (and generally paired) dorsal segments extending posteriorly from the snout to incorporate portions of the second or third body annulus. All specimens with one or even two postsupralabials and a zone of variously fused and enlarged segments in the "postocular" region dorsal to these. A lateral groove, filled with small, intercalated triangular segments, between the first third to half of the body and vent. Dorsal sulcus variably expressed; ventral sulcus, if present, indicated only by alignment of sutures. Median ventral segments generally enlarged. In some species, fused into an azygous medial segmental shield. Males of all species with precloacal pores; females of some species without pores or even secretion cores. All species (but C. williamsi) with a caudal autotomy constriction. Distal tip of original tail usually regularly segmented, occasionally showing modifications, such as a dorsal hump or inclined array of segments.
