DiagnosisDiagnosis. Enyalioides anisolepis can be distinguished from other species of Enyalioides, except for E. heterolepis, by having conical dorsal head scales (only in E. anisolepis and E. heterolepis) and scattered, projecting, large scales on the dorsum, flanks, and hind limbs (also in E./Morunasaurus annularis and E./M. groi), which are conspicuous in adults of both sexes (Fig. 7). Besides occurring on opposite sides of the Andes, E. anisolepis differs from E. heterolepis (character states from Torres-Carvajal et al. 2011 in parentheses) in having fewer vertebral scales, 43–62, 50.87 ± 6.27 (52–98, 74.61 ± 10.39), a higher vertebral crest with the vertebrals on neck at least three times higher than those between the hind limbs (ver- tebrals on neck maximum twice as high as those between hind limbs), scattered dark spots on belly in juveniles and adults of both sexes (belly without scattered dark spots, blackish medially in some adult males), tail in adult males moderately compressed laterally (strongly compressed), and a marked sexual dichromatism (Fig. 6), with the dorsal background color greenish in males and brownish in females (both sexes with a brownish background).
The only other species of Enyalioides with scattered, projecting dorsal scales is E. cofanorum, which differs from E. anisolepis in lacking projecting scales on the hind limbs, and in being smaller in size (maximum SVL in males and females of E. cofano- rum 107 mm and 109 mm, respectively; 130 mm and 119 mm in E. anisolepis). Ad- ditionally, adults of both sexes of E. cofanorum have a brownish background (marked sexual dichromatism in E. anisolepis). 
EtymologyThe specific epithet anisolepis is a noun (in apposition) in the nomina- tive singular and derives from the Greek words anisos (= unequal) and lepis (= scale). It refers to the heterogeneous scales on the dorsum, flanks and hind limbs of lizards of this species.
