Abstract
Based on morphological features, genetic distances, and phylogenetic relationships, we report the discovery of two new species of Enyalioides from the montane forest of Cordillera de Colán in northern Peru. The first new species can be distinguished from its congeners by the combination of the following characters: scales immediately posterior to superciliaries on lateral edge of skull conical, slightly higher than adjacent scales; gular scales heterogeneous in size; scales on neck mostly large and conical; dorsal scales between dorsolateral crests covered by large, keeled, mucronate scales; scales on flanks tiny, tuberculate or granular, with scattered enlarged conical or tuberculate scales; ventral scales keeled or feebly keeled; caudal scales heterogeneous, increasing in size posteriorly on each segment; and marked sexual dichromatism. Among other features, the second new species differs from other Enyalioides in having a distinctively low vertebral crest; scales immediately posterior to superciliaries on lateral edge of skull barely projected and similar in height to adjacent scales; 56-71 vertebral scales from occiput to base of tail; dorsal scales feebly keeled and heterogeneous in size; ventral scales keeled; and caudal scales heterogeneous, increasing in size posteriorly on each segment. In addition, we present an updated identification key for species of Hoplocercinae.
