TypesHolotype: KU 146658 
DiagnosisDiagnosis. This species can be distinguished from other species of Enyalioides by the combination of the following characters: scattered, projecting, large dorsal scales (inconspicuous or absent in some juvenile and male individu- als) between fore and hind limbs; strongly keeled ventrals; large dark patch on posterior aspect of gular region in both sexes; and light stripe extending from postympanic region to scapular region. The only other species of Enya- lioides with scattered, projecting dorsal scales is E. heterolepis, from which E. cofanorum differs in lacking pro- jecting scales on the hind limbs. In addition, males and females of E. cofanorum (maximum SVL = 107 mm and 109 mm, respectively) are smaller than those of E. heterolepis (maximum SVL = 137 mm and 115 mm, respec- tively), and these two species occur on opposite sides of the Andes. Among other species occuring east of the Andes, specimens of E. cofanorum lacking the projecting dorsal scales are similar morphologically to specimens of E. microlepis (character states in parentheses) and can be distinguished from them by having conspicuous dorsolat- eral crests between hind limbs (inconspicuous or absent), and a smaller body size (maximum SVL = 127 mm and 116 mm in males and females, respectively) [from TORRES-CARVAJAL et al. 2011].
