SPECIES Peromyscus merriami

Author:Mearns, 1896.
Citation:Preliminary diagnoses of new mammals from the Mexican border of the United States: p. 2; preprint of Proc. U. S. Nat. Mus., 19:138.
Common Name:Merriam’s Deermouse
Type Locality:México, Sonora, Sonoyta, on Sonoyta River.
Distribution:SC Arizona, USA, through W Sonora to C Sinaloa, México.
Status:IUCN – Lower Risk (lc).
Comments:P. eremicus species group. Osgood (1909) placed merriami under P. eremicus, a synonymy overturned by Hoffmeister and Lee (1963a), who documented their sympatric occurrence and morphological differentiation. Geographic variation evaluated by Hoffmeister and Diersing (1973), who retained goldmani as a subspecies; Lawlor (1971b) did not. Generally related to to P. eremicus sensu lato (Avise et al., 1974; Lawlor, 1971a) and to P. pembertoni (Lawlor, 1971a, 1983); based on mitochondrial DNA sequences, viewed as cognate species to P. eremicus sensu stricto, which together form a sister group to the clade P. eva P. fraterculus (Riddle et al., 2000a, c). Includes the insular form dickeyi according to mitochondrial DNA (COIII) comparisons (Hafner et al., 2001).
