Abstract

We describe a new species of Tupinambis from central South America in a transitional region between Amazonia, Cerrado, and Pantanal. The new species differs from its congeners by the number of femoral pores, posterior gulars, and mesoptychial scales and by color pattern. It is partially sympatric with Tupinambis cuzcoensis, Tupinambis longilineus, Tupinambis quadrilineatus, and maybe also with Tupinambis teguixin, but in general terms they tend to substitute one another in space.

Resumo

Descrevemos uma nova espécie de Tupinambis da região central da América do Sul, em uma área de transição entre Amazônia, Cerrado e Pantanal. A nova espécie difere das congêneres pelo número de poros femorais, escamas gulares posteriores, escamas entre as dobras antegular e gular, e padrão de coloração. É simpátrica com Tupinambis cuzcoensis, T. longilineus, T. quadrilineatus e tavez também com Tupinambis teguixin, mas em termos gerais essas espécies tendem a se substituir geograficamente.
