SPECIES Sigmodon (Sigmodon) alleni
| Author: | Bailey, 1902. | | Citation: | Proc. Biol. Soc. Wash., 15: 112. | | Common Name: | Allen’s Cotton Rat | | Type Locality: | México, Jalisco State, Mascota, Mineral San Sebastián. | | Distribution: | W México, from S Sinaloa to S Oaxaca. | | Status: | IUCN – Lower Risk (lc). | | Comments: | Subgenus Sigmodon, S. hispidus species group. Sister species to S. hirsutus according to phylogenetic interpretation of cytochrome b data (Peppers and Bradley, 2000). The forms guerrerensis and vulcani appear to be proper synonyms of S. alleni, but the status of the Oaxacan populations described as macdougalli and macrodon deserves renewed study and confirmation. Formerly included planifrons according to Baker’s (1969) revision, here regarded as a species. See Shump and Baker (1978, Mammalian Species, 95). |
