Abstract

We describe a new species of Anolis from the southeastern slopes of the Andes of Ecuador, province of Zamora-Chinchipe, Parque Nacional Podocarpus. It belongs to (1) the aequatorialis species-group by being of moderate to large size with narrow toe lamellae, and (2) the eulaemus sub-group by having a typical Anolis digit, in which the distal lamellae of phalanx II distinctly overlap the proximal scales of phalanx I. The new species is most similar morphologically to Anolis fitchi but differs from it mainly by having a dewlap with longitudinal rows of 2−5 granular, minute scales separated by naked skin (longitudinal rows of one or two keeled, large scales separated by naked skin in Anolis fitchi) and a vertically shorter dewlap (longer dewlap in Anolis fitchi).

Highlights

  • The lizard genus Anolis is the most species-rich genus of amniotes, with nearly 400 described forms (Poe 2004; Nicholson 2002)

  • During revisionary work on anoles of Ecuador, we examined some specimens of Anolis similar to A. fitchi Williams and Duellman 1984 collected at the Parque Nacional Podocarpus in southeastern Ecuador

  • We found that the color pattern of these specimens differed dramatically from typical A. fitchi
