Dusky Brown-toothed Shrew

Chodsigoa furva

French: Musaraigne de Birmanie / German: Dunkle Braunzahnspitzmaus / Spanish: Musarana de dientes marrones oscura

Other common names: Dark Brown-toothed Shrew, Dusky Long-tailed Shrew

Taxonomy. Chodsigoa smithii furva Anthony, 1941 ,

“Imaw Bum, northern Burma [= My- anmar]. Altitude 9,000 feet [= 2743 m].”

Chodsigoa furva was recognized as a subspecies of C. parca but was supported as a valid species. Monotypic.

Distribution. Known from only a few localities in in SW China (NW Yunnan) and adjacent N Myanmar; distribution limits are unclear.

Descriptive notes. Head—body 69-75 mm, tail 84-87 mm, hindfoot 16-18 mm. No specific data are available for body weight. Condylo-incisive lengths are 20-2-21-1 mm, and tooth rows are 8-6-9-2 mm. Dorsal pelage of the Dusky Brown-toothed Shrew is dark gray, and ventral pelage is slighter paler. Tail is not sharply bicolored, and no tuft of longer hair occurs on tip oftail. Rostrum is sharply narrowed in premaxillary region. Braincase is very dome-shaped. Zygomatic plate is narrow. The Dusky Brown-toothed Shrew is sister species of Smith’s Brown-toothed Shrew (C. smithit), but its body and skull are relatively smaller than the latter. There are three upper unicuspids.

Habitat. Captured at elevations higher than 2000 m. The Dusky Brown-toothed Shrew is presumably a high-elevation inhabitant, adapted to relatively cool environments. It was “trapped in a damp, oozy spot under logs and rocks next to small mountain stream.” Food and Feeding. No information.

Breeding. No information.

Activity patterns. No information.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The IUCN Red List. The Dusky Brown-toothed Shrew was considered as part of Lowe’s Brown-toothed Shrew ( C. parca ), which is classified as Least Concern. The Dusky Brown-toothed Shrew is one of the least known species of shrews. Few specimens are known in scientific collections, and all are from three mountains. It might be threatened by habitat loss due to deforestation in northern Myanmar (= Burma).
