Abstract

We document the first verifiable records of Heloderma alvarezi (Bogert & del Campo, 1956) in southeastern Guerrero, Mexico. We recorded seven individuals of H. alvarezi near the village of Cihuapoloya, municipality of Cuautepec. These are the westernmost records of the species, extending its distribution by approximately 149 km from the nearest previously known occurrences in Oaxaca. With these records, the number of reptile species in Guerrero increases to 182.
