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.

    ABSTRACT: We describe a new species of Phyllodactylus from a xerophytic forest in the Andes of southern Ecuador. The new species differs from other mainland species of Phyllodactylus from South America by the combination of the following characters: preanal scales similar in size to other ventral scales, well-defined longitudinal rows of tubercles dorsally, a medial longitudinal row of enlarged caudal scales ventrally, tubercles on dorsal surface of tibia present, enlarged postanal scale absent, tubercles on dorsal surface of forearm absent, interorbital scales homogeneous in size, enlarged scales on proximal one-fourth of tail absent, gular scales granular, and maximum snout–vent length of 55 mm. Even though morphological similarity suggests a close relationship between the new species and Phyllodactylus reissii, phylogenetic analyses of 10 nuclear and mitochondrial genes contradict this hypothesis. We also report the first records of Phyllodactylus kofordi for Ecuador.

    ABSTRACT: We report the discovery of two sympatric new species of Enyalioides from a montane rainforest of the Río Huallaga basin in northeastern Peru. Among other characters, the first new species is distinguishable from other Enyalioides by the combination of the following characters: strongly keeled ventral scales, more than 37 longitudinal rows of dorsals in a transverse line between the dorsolateral crests at midbody, low vertebral crest on the neck with vertebrals on neck similar in size to those between hind limbs, projecting scales on body or limbs absent, 96 mm maximum SVL in both sexes, and caudals increasing in size posteriorly within each autotomic segment. The second new species differs from other species of Enyalioides in having strongly keeled ventral scales, scales posterior to the superciliaries forming a longitudinal row of strongly projecting scales across the lateral edge of the skull roof in adults of both sexes, 31 or fewer longitudinal rows of strongly keeled dorsals in a transverse line between the dorsolateral crests at midbody, vertebrals on neck more than five times the size of vertebrals between hind limbs in adult males, projecting scales on body or limbs absent, and caudals increasing in size posteriorly within each autotomic segment. We also present an updated molecular phylogenetic tree of hoplocercines including new samples of Enyalioides rudolfarndti, Enyalioides rubrigularis, both species described in this paper, as well as an updated identification key for species of Hoplocercinae.
