Emended diagnosis: Males and females of C. petropolium can be distinguished from congeners by the presence of three square marks on the dorsum of opisthosoma ( Figs. 1A–B, 3C, 4C). Males are distinguished by the lack of a tibial apophysis on leg I, having a stout apical spine on tibia I ( Fig. 4D), and by the curved and short embolus of the palpal bulb ( Figs. 4E–F). Females are distinguished by the spermathecae with two receptacles with many apical lobes ( Fig. 3D).
