Tropidurus teyumirim

Tropidurus teyumirim, n. sp., is diurnal, heliophilous, and saxicolous, hardly differing from T. guarani with respect to its ecology. It uses the same types of sedimentary rocks as its congener and has similar coloration pattern, which provides camouflage against the lichenous background. Nothing is known about the dietary preferences of T. teyumirim, n. sp. Tropidurus teyumirim, n. sp., uses rock surfaces for basking and seeks shelter underneath rock blocks and in rock crevices. Lizards can be found lying dormant underneath rock blocks early in the morning when temperatures are still low. The species was never observed on three trunks along the limits or inside the forests surrounding the exposed sedimentary terraces. Tropidurus teyumirim, n. sp., is syntopic with Notomabuya frenata (Cope, 1862) and an undescribed species of the genus Ameivula at the Parque Nacional Ybycui, however, aspects of their interactions are unknown.
