The northernmost distributed group of lizards belonging to Phymaturus occurs
in rocky outcrops of the Puna region living between 3600–4200 m in
Argentina. In a recent phylogenetic study based on morphological and
genetic information, the monophyly of this small lineage was
corroborated. This group is formed by Phymaturus antofagastensis, P. laurenti, P. denotatus, P. mallimaccii
and a population of uncertain taxonomic status until the present study.
After obtaining new samples and observations we describe a new species
belonging to this lineage which is known only from Sierra de Fiambalá,
being the species of Phymaturus living at the highest elevation ever
recorded (4500 m). Males have a homogeneous yellow dorsum and lack
melanic coloration over their heads, a phenomenon found in males of
most species of the palluma
group. We provide a detailed diagnosis including characters from the
squamation, coloration, and significant differences found among
continuous characters (ANOVA). Furthermore, we present genetic
distances among members of the mallimaccii
subclade based on sequences of the cytb marker. We provide color photos
showing pattern variation of males and females. We reanalyze the
phylogenetic relationships within the entire palluma group updating
info on all members of the antofagastensis lineage based on new samples and find a better supported hypothesis. We evaluate the phylogenetic position of the new taxon.
