Taxonomy
The genus Soriculus is placed within the tribe Nectogalini. Several former species of the genus has been moved to other genera such as Chodsigoa and Episoriculus . [1] Species from the extinct European genus Asoriculus were also included here at one point. Currently the genus contains the extinct species Soriculus kashmiriensis and Soriculus kubinyi, [2] although in its description S. kashmiriensis was noted for being most closely related to species now placed in the genus Chodsigoa. [3] DNA research has confirmed the close relationship of Soriculus with the recently extinct Asoriculus and Nesiotites shrews from Europe. [4]
Until 2023, only a single species Soriculus nigrescens, was generally considered valid. In 2023 two additional living species belonging to the genus, Soriculus nivatus and Soriculus medogensis were proposed, with S. minor, previously regarded as a subspecies of Soriculus nigrescens, being proposed as a distinct valid species. [5] In 2024 the species Soriculus beibengensis was also proposed. [1]
