Uma nova espécie de Ameiva (Lacertilia; Teiidae) do Pantanal da Nhecolândia, Mato Grosso do Sul, Brasil

Abstract

We describe a new species of Ameiva with distribution restricted to an area of ​​the floodplain of Mato Grosso do Sul, Brazil, supported by morphology and molecular analysis (16S). Endemic to the Pantanal associated with Cerrado areas. Bayesian Inference (BI) phylogenetic analyzes showed three undisputed taxonomic groups among Ameiva spp., with the Pantanal species sharing the same group with A. jacuba and A. parecis. Furthermore, Ameiva sp. n. includes among the diagnostic characters, its color pattern and the combination of meristic characteristics, such as the range of variation in the number of supralabials, infralabials, scales around the tail, dorsal scales, rows of ventral scales in a transverse line, femoral pores , precloacal and lamellae scales of the fourth toe.
