Abstract

We present data about sexual dimorphism of two amphisbaenian species, Leposternon microcephalum and Leposternon wuchereri. Specimens were collected during faunal rescues in the course of the flooding process of four different hydroelectric dams, Santa Clara, Funil, Candonga and Ponte Hydroelectrics, at the Minas Gerais state, southeastern Brazil. Both species exhibited sexual dimorphism for different morphometric variables. While males of L. microcephalum have wider heads than conspecific females, males of L. wuchereri have wider, longer and taller heads than females but are smaller in body size.
