          Abstract

          The geographical differentiation of Amphisbaena fuliginosa L. is studied with basis on 220 specimens from 99 definite and 2 generic localities, ranging from Panamá to Puno in Peru and Goiás in Brasil. The pattern found is considered to support Vanzolini's 1951 scheme of five subspecies, defined by color pattern and by four meristic characters, and differentiated in consequence of Quaternary paleoecological events. Recent developments relating to models of differentiation in Quaternary tropical South America are briefly considered.

          A diferenciação geográfica de Amphisbaena fuliginosa (Reptilia, Amphisbaenia, Amphisbaenidae) é estudada com base em 220 exemplares de 99 localidades definidas e 2 localidades genéricas. O padrão encontrado apoia a conclusão de Vanzolini (1951) de que são reconhecíveis sub-espécies, definidas pelo padrão de colorido e por 4 caracteres merísticos. Esse padrão de diferenciação resultaria de eventos paleoclimáticos Quaternários. Contribuições recentes sobre modelos de diferenciação no Quaternário da América tropical são brevemente discutidos.
