French: Crocidure de Fischer / German: FischerWeil 3zahnspitzmaus / Spanish: Musarana de Fischer

Other common names: Fischer's Shrew

Taxonomy. Crocidura fischeri Pagenstecher, 1885 View in CoL ,

Nguruman , Kenya.

Phylogenetic relationships uncertain. Perhaps closely related to C. macarthur, as they are superficially very similar, although C. fischeri is larger; might be related to C. voi . Monotypic.

Distribution. Known only from the type locality N of Lake Natron, SC Kenya, and Himo, NE Tanzania. View Figure

Descriptive notes. Head—body 82-97 mm

(males) and 65-92 mm (females), tail 41-57 mm (males) and 42-57 mm (females),

ear 7-5—10-5 mm (males) and 9-4—11-7 mm (females), hindfoot 13-2—13-5 mm (males) and 12-13 mm (females); weight 14-5-15 g (males) and 11-15 g (females). Fischer's White-toothed Shrew is a distinctive medium-sized species. Dorsal pelage is bluish gray with a brownish tinge; ventral pelage is white, the hairs being gray on the basal half and white on the distal half. The upperlips, throat, behind the ears, and feet are white, with hairs like those on the ventrum. Tail is of medium length (c.53% of head-body length in males, ¢.59% of head-body length in females), pale pink, thick at the base and tapering toward tip, and is very hairy with longer bristle hairs all over. The upper first incisor is long and hooked; first unicuspid is very large and the second and third are half the size; M? is small. There are three unicuspids.

Habitat. Fischer’s White-toothed Shrew is a dry-savanna specialist that is not present in mountainous areas. It has been recorded at ¢.800 m.

Food and Feeding. No information.

Breeding. Three females with perforated vaginas were captured in June, suggesting that they were reproductively active, although the males captured at this time were not reproductively active.

Activity patterns. Fischer's White-toothed Shrews are terrestrial and nocturnal.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Data Deficient on The IUCN Red List. Fischer's White-toothed Shrew is locally abundant, accounting for 78% of the shrews captured in Nguruman, Kenya. The range is, however,restricted and the species is very poorly known. Further study is needed.
