Peromyscus furvus J. A. Allen and Chapman 1897
Peromyscus furvus J. A. Allen and Chapman 1897, Bull. Am. Mus . Nat. Hist., 9: 201.
Type Locality: México, Veracruz, 1.5 mi (2.4 km) E Jalapa, 4400 ft (1341 m).
Vernacular Names: Blackish Deermouse.
Synonyms: Peromyscus angustirostris Hall and Alvarez 1961; Peromyscus latirostris Dalquest 1950 .
Distribution: Wet and cool forests along E flanks of Sierra Madre Oriental from extreme SE San Luis Potosí to NC Oaxaca, México.
Conservation: IUCN – Lower Risk (lc).
Discussion: P. furvus species group. Morphological limits, geographic variation, and distribution reviewed by Huckaby (1980), nongeographic variation by Martínez-Coronel et al. (1997). Full synonyms include latirostris (see Hall, 1971) and angustirostris (see Musser, 1964), a conclusion supported by electrophoretic study of allozymes (Harris and Rogers, 1999). Specific homogeneity of taxon questioned by phylogeographic analysis of cytochrome b sequences (Harris et al., 2000), which suggests that the status and identity of populations in northernmost Oaxaca be reconsidered. Considered a member of the mexicanus group by Hooper (1968); segregated as P. furvus species group, tentatively including P. mayensis and P. ochraventer, by Carleton (1989). Although well differentiated from other mexicanus group forms, based on very limited taxonomic sampling, kinship with P. ochraventer is more distant according to mitochondrial DNA analyses (Harris et al., 2000).
