Peromyscus stirtoni Dickey 1928

Peromyscus stirtoni Dickey, 1928 Distribution. Choluteca, Francisco Morazán, El Paraíso, and Valle departments (Fig. 6). Ecoregions and elevation. Central American dry and pine-oak forests (200–900 m a. s. l.). Comments. P. stirtoni was initially assigned to the P. mexicanus group (Hall and Kelson 1959). However, this placement was questioned and considered provisional by Carleton (1989). Subsequent mtDNA studies conducted by Bradley et al. (2007) and Ordóñez-Garza et al. (2010) suggested that P. stirtoni should be placed within the P. megalops species group. León-Tapia et al. (2022) reported that P. stirtoni forms a well-supported monophyletic lineage, but it is important to note its close relationship with lowland species, including the P. megalops group. In contrast, Bradley et al. (2016) considered P. stirtoni to be in the P. mexicanus group. Timm (2016) suggested that P. stirtoni might occur in La Paz, southern Comayagua, Lempira, Ocotepeque, and Intibucá departments, but this remains to be confirmed.
