Diversity
47 species

Phymaturus is a genus of iguanian lizards of the family Liolaemidae, a family which was traditionally included in the Iguanidae as a subfamily, but more recently was proposed to warrant distinct family status. Phymaturus is the mid-sized genus of its family, with 47 species altogether known as of 2017;[2] new species are still being discovered however.[3]

Species of the genus Phymaturus are found in the Andes region south to Patagonia and inhabit a variety of habitats. Their habits are mostly conserved from the ancestral iguanians, in that Phymaturus are generally inhabitants of rocky ground, feed on plants, and give birth to fully developed young.[3]

Systematics[edit]

The genus can be divided into two lineages, which probably represent clades:

palluma group

Superciliar scales not imbricate, more than four subocular scales, 3-4 rows of lorilabial scales, mental scale narrower than rostral scale and usually touching the sublabial scales. Tail spines well-developed, two annuli per segment.[3]

patagonicus group

Superciliar scales elongate and overlapping, one usually unfragmented subocular scale, tail smooth, Meckel's groove fused and closed.[3]

More species which may or may not belong to the aforementioned species groups:[5]

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Phymaturus.
