MetadataShow full item record
ABSTRACT: We describe four new species of anoles (genus Anolis) from the Serranı´a de Tabasara´, westcentral Panama. Two of the new species are most similar in external morphology to a cluster of Central American species that are short-legged (fourth toe of adpressed hindlimb reaches only to tympanum), have a single elongated prenasal scale, smooth ventral scales, and slender habitus, often delicate. They differ from the other species in this cluster by hemipenial morphology and scalation characteristics. One of the new species appears to be most similar to A. pachypus and A. tropidolepis from which it differs by male dewlap coloration and its very small dorsal head scales. The fourth new species appears to be most similar to A. laeviventris from which it differs by its multicarinate head scales, lack of heterogeneous flank scalation, and an overall green coloration.
