De Winton’s Brown-toothed Shrew <i>Chodsigoa hypsibia</i> <b>French:</b> Musaraigne de De Winton / <b>German:</b> De Winton-Braunzahnspitzmaus / <b>Spanish:</b> Musarana de dientes marrones de De Winton <b>Other common names:</b> De Winton's Shrew <b>Taxonomy.</b> Soriculus hypsibius de Winton, 1899, “ Yang-liu-pa,” Sichuan, China. Chodsigoa hypsibia includes beresowskii and lamula as synonyms; the latter was sug- gested as conspecific with C. hypsibia in a comprehensive study. Chodsigoa hypsibia comprises a cryptic lineage from its southernmost distribution. Subspecies boundary is unclear and requires additional research. Two subspecies recognized. <b>Subspecies and Distribution.</b> C.h.hypsibiadeWinton,1899—C&amp;SC.h.(SEQinghai,SGansu,SShaanxi,ETibet[=Xizang],Sichuan,NYunnan,andSAnhui),inmiddletohighelevationalmountainsSofHuangHe. C. h. larvarum Thomas, 1911 — known only from two localities in Shanxi (Luya Shan) and Hebei, N C.h. <b>Descriptive notes.</b> Head-body 62-86 mm, tail 56-73 mm, hindfoot 13-18 mm. No specific data are available for body weight. Condylo-incisive lengths are 19-22-6 mm, and tooth rows are 7-8-9-4 mm. Dorsal pelage of De Winton’s Brown-toothed Shrew is slate-gray, and venter is brownish gray. Tail is shorter than head-body length and not sharply bicolored. Tuft of slightly longer hair occurs on tip oftail. Rostrum gradually narrows in premaxillary region. Skull is low, and braincase is markedly flattened. Specimens assigned to taxon lamula represent extreme examples toward low braincase that is only 4-2 mm high. De Winton’s Brown-toothed Shrew has three upper unicuspids. Molecular evidence found southernmost population as a cryptic lineage that is morphologically indistinguishable. De Winton’s Brown-toothed Shrew is closely related to the Pygmy Brown-toothed Shrew (C. parva), which is much smaller. Dental formula for all species of Chodsigoais13/2,C1/0,P1/1,M 3/3 (x2) = 28. <b>Habitat.</b> Cultivated farmland, shrubland, and deciduous broad-leaved and coniferous forests at elevations of 1200-3500 m. In each specific region of the distribution, De Winton’s Shrews occupy narrow elevational ranges. <b>Food and Feeding.</b> De Winton’s Brown-toothed Shrew is insectivorous. <b>Breeding.</b> No information. <b>Activity patterns.</b> No information. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Least Concern on The IUCN Red List. De Winton’s Brown-toothed Shrew has a large distribution across a wide range of elevations and seems to have some tolerance for habitat modification. <b>Bibliography.</b> Chen Zhongzheng et al.
