Abstract
The Motagua River Basin is a transboundary watershed shared by Guatemala and Honduras. To create a comprehensive checklist of fish species in the Honduran section of this basin, we conducted an extensive review of scientific and gray literature, followed by fieldwork to verify occurrence data. Our results show that the Honduran Motagua fish fauna comprises 52 species from 45 genera, 23 families, and 15 orders. The family Poeciliidae is the most diverse with 11 species, followed by Cichlidae with 10. We newly report 11 species for the Motagua River Basin. This study provides the most complete checklist for this basin to date, establishing a foundational reference for future biogeographic, ecological and conservation research in the region.
