Holotype: "Male holotype from Tehachapi Mountains, California, September 8, 1914, in the American Museum of Natural History" (Muma, 1962, p. 29).

Chelicerae Description: "Dentition also similar to that of C. regalis. The most striking difference in dentition is the constriction and attenuation of the fixed finger of the present species (fig. 41). Another distinct difference is the complete lack of fondal teeth I and II on this species, whereas C. regalis has these teeth small but distinct. In addition there are two tiny supernumerary intermediate teeth on the movable finger" (Muma, 1962, p. 29).

Palp Description: "Structure similar to that of C. regalis, but this species lacks a scopula on the metatarsus of the palpus whereas C. regalis has a basal scopula composed of numerous papillae" (Muma, 1962, p. 29).

Diagnosis: "This species, C. rectus, new species, and C. regalis are closely related but can be distinguished readily by the characters given in the key above. The lack of a palpal scopula is particularly diagnostic. A female collected by V. Roth from Sonora, Mexico, 20 miles southeast of San Luis R. C., Laguna Prieta, June 6, 1959, has supernumerary intermediate teeth on the movable finger and probably belongs in this species" (Muma, 1962, p. 29).
