Amphisbaenians, municipality of São Paulo, state of São Paulo, Southeastern Brazil.

Abstract

We provide a checklist, distribution map, and key to the amphisbaenians of the municipality of SãoPaulo. Seven species in three genera were recorded. Between August 2003 and June 2007, 104 individuals in twogenera and five species were received at the Laboratório de Herpetologia of the Instituto Butantan: Amphisbaenaalba, A. dubia, A. mertensi, A. trachura, and Leposternon microcephalum. Records for two additional species,Amphisbaena hogei and Cercolophia roberti, were recovered at the Museu de Zoologia da Universidade de SãoPaulo. Two widely distributed species, Amphisbaena dubia and Leposternon microcephalum, present differentdistribution patterns, probably reflecting the distribution of open and forested areas in the studied region, close tocontact areas between the Atlantic Forest and adjacent open formations. Most amphisbaenians seem to endurehabitat modifications in urbanized areas, but some species as A. hogei and C. roberti are no longer recorded in theSão Paulo area.
