ABSTRACT We describe a new species of Enyalioides from mid-elevation rainforests in southeastern Ecuador. This represents the fifth species of Enyalioides known to occur east of the Andes in South America; the other four species are E. cofanorum, E. laticeps, E. microlepis and E. praestabilis. Among other characters, the new species can be distinguished from other Enyalioides by having distinct caudal whorls, fewer than 32 longitudinal rows of dorsals at midbody, and bright orange to red gular scales bordered with black in adult males. Morphological similarity suggests that the new species, which we call E. rubrigularis, is closely related to E. praestabilis.

    ABSTRACT: The Cordillera del Cóndor is an area rich in unique vegetation assemblages and endemic faunal elements; the herpetofauna is especially diverse, particularly the anurans. The montane forest and sandstone tepuis, located atop large andesite and quartz formations, provide a variety of habitats and microhabitats in which the herpetofauna finds food, shelter, and reproductive sites, such as terrestrial and arboreal bromeliads and a soil type termed “bamba” that is covered with mosses and roots. Information compiled from publications and recent studies has revealed the presence of 120 species of amphibians and 59 species of reptiles, including 41 probable new species (36 amphibians and five reptiles) in the genera Centrolene, Dendrobates, Pristimantis, Lynchius, Chiasmocleis, Bolitoglossa, Anolis, Erythrolamprus, Tantilla, and Dipsas.
