Abstract
We report a disjunct population of Dicrodon guttulatum Duméril & Bibron, 1839 on the eastern slope of the Cordillera 
Occidental in the inter-Andean Seasonally Dry Forests of the Marañón River, in the Departments of Cajamarca and 
Piura in northwestern Peru. We include an updated range distribution map using records from museum specimens, the 
Global Biodiversity Information Facility, and available photographic records on iNaturalist. In addition, we identify 
widespread cultivation of rice crops as the main threat to D. guttulatum in the inter-Andean Seasonally Dry Forests of 
the Marañón.
