Southern Grasshopper Mouse

While 10 subspecies of southern grasshopper mouse were recognized in 1975, ITIS currently recognizes 7 subspecies.

Taxonomic accounts prepared by Hollister (1914) with a revision for Arizona by Van Cura and Hoffmeister (1966) described 10 distinct subspecies in the southern grasshopper mouse in 1975. O. torridus was described to be principally found in low, arid, scrub and semi-scrub vegetation of deserts in the Lower Sonoran Life-zone from western Nevada, southern California, and southwestern Utah, south to central Mexico, and east to western Texas. In areas of sympatry with the northern grasshopper mouse (Onychomys leucogaster), there was evidence that O. torridus occupied areas of lower elevation.

Seven subspecies are currently recognized by the Integrated Taxonomic Information System (ITIS): O. t. canus, O. t. clarus, O. t. perpallidus, O. t. ramona, O. t. surrufus, O. t. tularensis, and O. t. yakiensis.
