| Diagnosis | Diagnosis: Crotaphyus nebrius can be distinguished from C. dickersonae, C. grismeri. C. bicinctures, C.vestigium, and C. insularis by the absence in adult males of a laterally compressed tail, enlarged dark brown or black inguinal patches that extend between one-third and one-half the distance between the hindlimb and forelimb insertions, and a pale white dorsal caudal stripe. It can be funher distinguished from C. grismeri, C. bicinctores, C. vestigium, and C. insularis by the presence of black oral melanin. It can be distinguished from C. reticufatusand C. antiquits by its dorsal color pattern of white spots on a pale tan field, rather than white reticulations on a pale tan or brown field and the absence of jet black femoral pores in males. It can be further distinguished from C. reticulatus by the presence in adult males of small dark brown or black inguinal patches. It can be distinguished from C. collaris by the presence in adult males ofdark brown or black pigmentation in the gular fold (= ventrally complete anterior collar) and by the presence of burnt orange ventrolateral abdominal coloration in breeding males (McGuire 1996: 88). |

| Etymology | The name nebrius comes from the Greek word nebrias meaning spotted like a fawn. This is in allusion to the distinctive large white dorsal spotting in this form. |
