Abstract

The rattlesnake Crotalus durissus terrificus (Laurenti, 1768; Serpentes, Viperidae) is a rare species in Uruguay, where it reaches the southern boundaries of its distribution. The most recent distribution map available for this species in Uruguay is based on a few specimens that were collected during the 1950s and 1960s. Herein, we make a comprehensive account of rattlesnake records in this country obtained from herpetological literature and other bibliographic sources, specimens accessioned in herpetological and non-specialized local collections, and new information gathered during field surveys.

Key words:

Crotalus; rattlesnakes; geographic distribution; decline
