SPECIES Sigmodon (Sigmodon) planifrons
Author: | Nelson and Goldman, 1933. | Citation: | Proc. Biol. Soc. Wash., 46: 197. | Common Name: | Miahuatlán Cotton Rat | Type Locality: | México, Oaxaca State, Juquila, 5000 ft (1524 m). | Distribution: | As so far known, limited to Sierra de Miahuatlán, S Oaxaca, México. | Comments: | Subgenus Sigmodon (S. hispidus species group?). Described as a species but relegated to a subspecies of S. alleni by Baker (1969). As noted by Nelson and Goldman (1933b), the diminutive size exhibited by the type series, as well as the material and sympatry later reported by Goodwin (1955b, 1969), suggests that the form is distinct from S. alleni; renewed study of the Oaxacan taxa named by Goodwin (1955b) will prove critical to much-needed revision of the S. alleni complex (see discussion in Carleton et al., 1999). |
