Iguanidae: Hoplocercinae) from Southwestern Ecuador
Volume 48(20):227-235, 2008 A new species of ENYALIOIDES (Iguanidae: Hoplocercinae) from southwestern Ecuador Omar Torres-Carvajal1,2 Ana Almendáriz3 Jorge Valencia4 Mario Yánez-Muñoz5 Juan P. Reyes5 ABStract We describe a new species of Enyalioides from lowland cloud forests in southwestern Ecuador. This represents the third species in the genus known to occur west of the Andes in South America; the other two species are E. heterolepis and E. oshaughnessyi. Among other characters, the new species can be distinguished from other members in the genus by having small, keeled, paravertebrals; a series of skin folds on the lateral aspects of body and neck; size-homogeneous scales on body and limbs; distinct caudal segments; and an extensive dark patch on the gular region of adult males. Morphological similarity suggests that the new species, which we call E. touzeti, is closely related to E. oshaughnessyi. Keywords: Ecuador, Enyalioides, Hoplocercinae, Iguania, new species.

Understanding how different environmental factors influence species occurrence is a key issue to address the study of natural populations. However, there is a lack of knowledge on how local traits influence the microhabitat use of tropical arboreal lizards. Here, we investigated the microhabitat selection of the poorly known lizard Tropidurus lagunablanca (Squamata: Tropiduridae) and evaluated how environmental microhabitat features influence animal’s presence. -

We also summarized data on lizard faunas for nine other well-studied areas in Amazonia to make pairwise comparisons among sites. The Biogeographic Similarity Coefficient for each pair of sites was calculated and plotted against the geographic distance between the sites. A Parsimony Analysis of Endemicity was performed comparing all sites. A total of 114 species has been recorded in the four studied sites, of which 45 are lizards, three amphisbaenians, and 66 snakes. The two sites between the Xingu and Madeira rivers were the poorest in number of species, those in western Amazonia, between the Madeira and Juruá Rivers, were the richest. Biogeographic analyses corroborated the existence of a well-defined separation between a western and an eastern lizard fauna. The western fauna contains two groups, which occupy respectively the areas of endemism known as Napo (west) and Inambari (southwest). Relationships among these western localities varied, except between the two northernmost localities, Iquitos and Santa Cecilia, which grouped together in all five area cladograms obtained. No variation existed in the area cladogram between eastern Amazonia sites. The easternmost localities grouped with Guianan localities, and they all grouped with localities more to the west, south of the Amazon River. -

This richness is represented by 35 species of turtles, fve crocodilians, and 437 squamates including three amphisbaenians, 197 lizards, and 237 snakes. Of these, 45 species are endemic to the Galápagos Islands and 111 are mainland endemics. The high rate of species descriptions during recent decades, along with frequent taxonomic changes, has prevented printed checklists and books from maintaining a reasonably updated record of the species of reptiles from Ecuador. Here we present Reptiles del Ecuador (http://bioweb.bio/faunaweb/reptiliaweb), a free, resource-rich online portal with updated information on Ecuadorian reptiles. This interactive portal includes encyclopedic information on all species, multimedia presentations, distribution maps, habitat suitability models, and dynamic PDF guides. We also include an updated checklist with information on distribution, endemism, and conservation status, as well as a photographic guide to the reptiles from Ecuador. -

ZooKeys 494: 107–132. doi: 10.3897/zookeys.494.8903 Abstract The discovery of three new species of Enyalioides from the tropical Andes in Ecuador and northern Peru is reported. Enyalioides altotambo sp. n. occurs in northwestern Ecuador and differs from other species of Enyalioides in having dorsal scales that are both smooth and homogeneous in size, a brown iris, and in lacking enlarged, circular and keeled scales on the flanks. Enyalioides anisolepis sp. n. occurs on the Ama- zonian slopes of the Andes in southern Ecuador and northern Peru and can be distinguished from other species of Enyalioides by its scattered, projecting large scales on the dorsum, flanks, and hind limbs, as well as a well-developed vertebral crest, with the vertebrals on the neck at least three times higher than those between the hind limbs.
