Peromyscus attwateri J. A. Allen 1895

Peromyscus attwateri J. A. Allen 1895, Bull. Am. Mus . Nat. Hist., 7: 330.

Type Locality: USA, Texas, Kerr Co., Turtle Creek.

Vernacular Names: Texas Deermouse.

Synonyms: Peromyscus bellus Bangs 1896; Peromyscus cansensis Long 1961; Peromyscus laceyi Bailey 1905 .

Distribution: Edwards Plateau (see Goetze, 1998) and E Llano Estacado (see L. Choate, 1997) of C and N Texas, eastwards through SW and E Oklahoma, to SE Kansas, SW Missouri, and NW Arkansas, USA.

Conservation: IUCN – Lower Risk (lc).

Discussion: P. truei species group. Cognate relationship to P. difficilis (and nasutus) suggested by allozymic data (Janecek, 1990; Sullivan et al. 1991), a relationship bolstered by restriction-site (DeWalt et al., 1993 b) and gene-sequence analyses (Tiemann-Boege et al., 2000) of mitochondrial DNA. Classified as a geographic race of P. boylii (Osgood, 1909) until rediagnosed as a species by Schmidly (1973). Biochemical evolution studied by Kilpatrick (1984); morphometric variation among Arkansas populations evaluated by Sugg et al. (1990). Populations found along the eastern escarpment of the Llano Estacado, N Texas, reidentified as P. attwateri, not P. boylii (L. Choate, 1997) . See Schmidly (1974, Mammalian Species, 48).
