Chaetodipus dalquesti Roth 1976

Chaetodipus dalquesti Roth 1976, J. Mammal., 57: 562.

Type Locality: Mexico, Baja California Sur, 4 mi SE Migriño.

Vernacular Names: Dalquest's Pocket Mouse.

Distribution: Cape Region of Baja California Sur (Mexico).

Conservation: IUCN – Lower Risk (lc) as included in C. arenarius .

Discussion: Considered a subspecies of C. arenarius by Patton (1993 b), Williams et al. (1993), and Patton and Alvarez-Castañeda (1999), with which it shares an identical karyotype (Hafner and Hafner, 1983). However, both mitochondrial DNA (Riddle et al., 2000 b) and morphology (D. J. Hafner, pers. comm.) suggest separate species status, although a complete analysis of the relationships of dalquesti to arenarius has not as yet been made.
