SPECIES Notiosorex cockrumi

Author:Baker, O'Neill, and McAliley, 2003.
Citation:Occas. Pap., Mus. Texas Tech Univ., 222: 2.
Common Name:Cockrum's Gray Shrew
Type Locality:USA, Arizona, Cochise Co., Leslie Canyon National Wildlife Refuge, T21S, R28E Section NW 1/4 20, 4460 ft. (1359 m).
Distribution:Arizona (USA) to C Sonora (Mexico).
Comments:A cryptic species indentified on the basis of cytochrome b gene fragments. Carraway and Timm (2000) included this new taxon in crawfordi and stated that they "found no identifyable morphological differences." Sympatric with crawfordi in SE Arizona. A karyotype of 2n = 62, FN = 94 reported earlier from Pima County, Arizona (Baker and Hsu, 1970), may refer to this species, while 2n= 68 and FN = 102 may refer to crawfordi. Molecular data also indicate that a third species occurs in Baja California (Baker et al., 2003a).
