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). |
