First records in Brazil for Arthrosaura versteegii van Lidth de Jeude, 1904 (Reptilia, Gymnophthalmidae), a possible species complex, and distribution extension for Arthrosaura montigena Myers & Donnelly, 2008, in Venezuela

Abstract

Arthrosaura versteegii van Lidth de Jeude 1904 has a supposed distribution on the Guiana Shield from eastern Venezuela to western French Guiana, between 100–1400 m above sea level. No records for Brazil were known. We here report material from two areas in Brazilian Amazonia south of the Amazon River, of specimens morphologically agreeing with mso-bidi-font-style: normalA. versteegii, but with two distinct types of hemipenes that also differ from that of Guianan males. Moreover, reexamination of two specimens of mso-bidi-font-style:normalA. versteegii reported from the Venezuela highlands show that they are A. montigena Myers and Donnelly 2008. This leaves A. versteegii restricted to eastern Amazonian lowlands.
