Liolaemus carlosgarini and Liolaemus riodamas (Squamata: Liolaemidae), two new species of lizards lacking precloacal pores, from Andean areas of central Chile.

摘要: Most of the lizards Liolaemus genus present precloacal pores in males, with few exceptions species lineomaculatus and neuquensis groups, elongatus-kriegi complex. The complex, belonging to ( sensu stricto ) subgenus, is composed medium sized, saxicolous, viviparous insectivorous or omnivorous lizards, distributed between Andean Patagonian zones Chile Argentina. We reviewed taxonomic history this group, we describe two new species, carlosgarini , found vicinity Maule Lagoon, Region, Chile, riodamas described from population that was originally designated as cf. ceii, Las Damas River, near Termas del Flaco locality, Libertador Bernardo O’Higgins thereby based on research L. ceii eliminated Chile. Both have a diagnostic character absence pores, suggest here their presumptive systematic relationships Liolaemus. analyzed ten order perform phylogenetic analysis external morphology, using mostly squamation morphometric characters. performed PAUP, Maximum Parsimony criterion. In addition, through diaphanisation, studied osteology species. conclude lacking do not form monophyletic constructing phylogeny only at least for group reptiles, insufficient establish solid phyletic relationships. Other sort characters should complement morphological ones.
