SPECIES Peromyscus dickeyi

Author:Burt, 1932.
Citation:Trans. San Diego Soc. Nat. Hist., 7: 176.
Common Name:Dickey’s Deermouse
Type Locality:México, Baja California Sur, Tortuga Isl; 27°21'N, 111°54'W.
Distribution:Known only from Tortuga Isl.
Status:IUCN – Endangered.
Comments:P. eremicus species group. Genically similar to P. eremicus and P. merriami (Avise et al., 1974) and presumably originated from an eremicus like progenitor (Lawlor, 1983), but gene sequence data decisively portray mice on Tortuga Isl as derivatives of P. merriami (Hafner et al., 2001). The last authors have recommended the recognition of dickeyi as a subspecies of P. merriami. Cranium and fur traits of dickeyi do closely resemble those of P. merriami but the bullae appear smaller and the tail relatively shorter, diagnostic features noted by Burt (1932). A sounder footing for its synonymy and possible subspecific retention should involve broader morphological and molecular surveys within the range of P. merriami, together with the original type series of the island form. See Cortés-Calva and Alvarez-Castañeda (2001, Mammalian Species, 659).
