Iguanian species-richness in the Andes of boreal Patagonia: evidence for an additional new Liolaemus lizard from Argentina lacking precloacal glands (Iguania, Liolaeminae)
Most Liolaemus lizard species are characterized by the presence of precloacal glands in males. Only a few taxa lack these sexual signal emitter structures. Phylogenetic evidence suggests that those species are restricted to the clades chiliensis and lineomaculatus. Within the first lineage, L. coeru...
