Peromyscus gymnotis Thomas 1894

Peromyscus gymnotis Thomas 1894, Ann. Mag. Nat. Hist., ser. 6, 14: 365.

Type Locality: " Guatemala." .

Vernacular Names: Naked-eared Deermouse.

Synonyms: Peromyscus allophylus Osgood 1904 .

Distribution: Pacific coastal plain and adjacent foothills, near sea level- 1675 m, from S Chiapas, México, to S Nicaragua, west of Lake Nicaragua (after Huckaby, 1980; Jones and Yates, 1983; Owen et al., 1990).

Conservation: IUCN – Lower Risk (lc).

Discussion: P. mexicanus species group. Formerly classified as a subspecies of P. mexicanus (Osgood, 1909); Musser (1971) elevated gymnotis to species and pointed out the junior status of allophylus . Differentiation from P. mexicanus sustained by Huckaby (1980) and Jones and Yates (1983), who also amplified the southern range and morphological recognition of P. gymnotis . As noted by Carleton (1989), the northward distribution in the region of the Isthmus of Tehuantepec now needs clarification, particularly in light of the report of a mexicanus sample from near Berriozábal, Chiapas, that genetically links with P. gymnotis (Rogers and Engstrom, 1992) .
