Resumen:
We describe a new species of Phymaturus from the Sierra La Invernada of San Juan Province, Argentina. The new species shares the apomorphies of the P. palluma group including a fragmented subocular, square nonimbricate superciliaries, rugose and strongly mucronate dorsal caudals, and a midvertebral band of enlarged scales. Within the P. palluma group, the new species can be assigned to the Puna clade, with which it shares a dorsal pattern of small, dispersed brown spots and lack of black reticulations. The new species differs from other members of the Puna clade in several aspects of squamation and body pattern and color. Most notably, the new Phymaturus has a conspicuous yellow scapular spot, lacks a vertebral stripe, and has incomplete dark pigmentation over the dorsal neck. The new species is known only from the region of the type locality, the southernmost (and geographically isolated) extent of the Puna phytogeographic province, where it occurs at high elevations (>3100 m). We provide information on aspects of the natural history, diet, thermal biology, and apparent parental care exhibited by females of the new species.
