Resumo

Amphisbaena rozei is endemic to the Caura River basin in Venezuela, and known only from the holotype and one paratype. Its original description is very brief, lacking relevant information used by taxonomists today. Additionally, A. rozei appears to be similar to A. spurrelli, a species from northwestern Colombia and southern Panama. We present a redescription of A. rozei based on the examination of the type specimens and compare this taxon to the other known South American amphisbaenids, especially A. spurrelli. We conclude A. rozei is a valid name, and the species is diagnosed mainly by the presence of four precloacal pores, a lateral sulcus, 205-209 body annuli, 20 caudal annuli, 15-16 dorsal and 14 ventral segments on a midbody annulus, and dorsal surface of tail covered by strong tubercles.
