Saussure’s Shrew
French: Musaraigne de De Saussure / German: Saussure-Spitzmaus / Spanish: Musarana de Saussure
Taxonomy. Sorex saussurei Merriam, 1892 View in CoL ,
“ Sierra de Colima , Jalisco, Mexico (alttude 8,000 feet [= 2438 m]),” but the type specimen tag has “Sierra Nevado,Jalisco.” Restricted by L. N. Carraway in 2007 to “latitude 19-55°N, longitude 103-63°W.”
Sorex saussurei seems to be closely related to S. mediopua, which it previously included. The saussurei group (also including S. altoensis and S. mediopua) is included in an unnamed subgenus of Sorex along with the trowbridgii group, the merriami group, the salvini group, and the veraepacis group and seems to be most closely related to the salvini group and the trowbridgii group. Sorex saussurei previously included S. salvini , S. mccarthyi, and S. madrensis before all three were recognized as distinct species in Guatemala; it also variously included S. emarginatus , S. veraepacis , S. altoensis, S. mediopua, and S. cristobalensis. Monotypic.
Distribution. Jalisco, Colima, Michoacan, México, Distrito Federal, Morelos and Puebla, SC Mexico. View Figure
