The genus Codatractus Lindsey, 1921 (Hesperiidae: Eudaminae) includes 17 taxa; three are endemic to México (C. yucatanus, C. cyledis, and C. uvydixa). The genus is distributed in the Neotropical and southern Neartic region, from southern Arizona, New Mexico, and Texas, across Mexico and Central America, to relatively dry regions of Ecuador, Venezuela, Brazil, Paraguay, and Argentina. We analyzed the geographical distribution of the genus, as correlated with climatic and physiographic factors, based on records from collections, literature, web sites, and field research. Results showed that the greatest number of species occur between 15 and 21°, below the Tropic of Cancer, between 0–1800 m, and are associated with dry forest. The greatest concentration of species occurs in the Balsas Depression and Mexican Pacific Coast. The distribution, diversity, and degree of endemism indicate the genus diversified in Mexico.
