| Abstract: | Sorex rohweri sp. nov. is described on the basis of a series of specimens from the Olympic Peninsula and adjacent western regions of Washington State, USA, and southwestern British Columbia, Canada. It has been misidentified as Sorex cinereus Kerr, 1792, which occurs in the Cascade Range in west-central Washington, in coastal British Columbia, and regions farther to the northeast. The new species is distinguished from S. cinereus by numerous morphological characters: differences in craniodental dimensions; different location and form of the medial tines of the upper incisors; presence of patent postmandibular foramina; different intensity and distribution of dental pigmentation; and different form of the glans penis, along with other details. The combination of characters also separates it from sympatric species of Sorex. Phylogenetic inference of cytochrome b sequences from two specimens of the proposed new species shows them to be distinct from Sorex cinereus and from five sympatric Sorex species, supporting their designation as members of a new species. |
