Distribution patterns of Stenocercus in southern Ecua- dor and northern Peru are influenced by the Huancabamba Depression, a region widely recognized as a major biogeo- graphic discontinuity for Andean organisms (Duellman, 1979). No species of Stenocercus is presently known from north and south of the depression (Cadle, 1991). Ten species (71 %) are endemic to Ecuador. Most of the Ecuadorian species occur south of 1°S Lat. Stenocercus iridescens has the greatest latitudinal distribution range (from 00°53' N to 05°55' S in northwestern Peru), whereas S. haenschi is known only from its type locality. Most of the Ecuadorian species of Stenocercus resemble the Andean liz- ard genera PhoUdobolus (Montanucci, 1973) and Proctoporus (Kizirian, 1996) in having limited geographic Table 14.

Ecological Distribution The ecological distribution of the Ecuadorian Stenocercus species is described in the species accounts. For analytical purposes, I used the classification of life zones of Ecuador proposed by Cafiadas-Cruz (1983), which is based on the Holdridge (1947) system. The distrib
