A Taxonomic Odyssey: An annotated checklist of Peromyscus (Cricetidae, Rodentia) in Honduras

Abstract

Deer mice, Peromyscus, thrive in diverse environments and altitudes across North and Central America. The number of extant species continues to be debated with species counts ranging from 53 to 83. This study represents the first comprehensive historical and taxonomic account of the genus Peromyscus for Honduras. We systematically compiled records from all available sources, incorporating verified genetic and morphological evidence. We confirm the presence of P. beatae, P. cordillerae, P. nicaraguae, P. salvadorensis and P. stirtoni for Honduras. The distribution maps provided here include confirmed records and approximate localities in a few cases and offer insights into the geographical distribution of these species in Honduras. Conducting a comprehensive assessment of the taxonomic status of Peromyscus in Honduras is imperative to achieve accurate conservation assessments within the larger Mesoamerican landscape. The present review establishes the baseline for future research on deer mice in Honduras, aiding in the validation of distributions and ecological data for the poorly understood genus Peromyscus in the country.
