Savanna Dwarf White-toothed Shrew

Crocidura nanilla View in CoL

French: Crocidure pygmée / German: Kleine Savannen-WeiRzahnspitzmaus / Spanish: Musarana enana de sabana

Other common names: Tiny White-toothed Shrew

Taxonomy. Crocidura nanilla Thomas, 1909 View in CoL ,

“ Uganda ( probably Entebbe ).”

Exact position of C. nanilla phylogeneti- cally is uncertain, although one genetic study placed it as sister to a clade includ- ing C. lamottei , C. flavescens , C. hirta , C. goliath , C. olivieri , C. viaria , and C. fulvastra . It is often confused with the similar C. pasha . Monotypic.

Distribution. West Africa in SW Mauritania, Senegal, Gambia, SW Mali, Guinea-Bissau, Guinea, and N Sierra Leone, and East Africa in Uganda, NW Kenya, and NE Tanzania; it has also been apparently recorded from Ivory Coast, Ghana, and Nigeria, although identity of these specimens needs to be confirmed.

Descriptive notes. Head-body 41-58 mm, tail 31-41 mm, ear 6-3-8 mm, hindfoot 8-2-10-5 mm. No specific data are available for body weight. The Savanna Dwarf White-toothed Shrew is very small, with short dense pelage. Dorsal pelage is dark grayish brown to dark blackish brown, and ventral pelage is medium gray and paler than dorsum, merging on lower flanks. Chin and throat are white or gray. Feet are dark brown and covered with short hairs. Tail is ¢.70% of head-body length, hairy, and bicolored, being dark brown dorsally and paler below. Dorsal surface of skull is convex,

crowns of teeth are relatively high, I' are long and hooked, and M? is medium-sized. There are three unicuspids. A specimen identified as a Savanna Dwarf White-toothed Shrew from Ivory Coast had the diploid number of 2n = 42 and FN = 74, but it might have been misidentified.

Habitat. Primarily dry and moist savanna. One Savanna Dwarf White-toothed Shrew was found in irrigated crops.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. No information.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The IUCN Red List. The Savanna Dwarf White-toothed Shrew is widespread, although it is known from very scattered records. It is considered common throughout much of its distribution, but virtually nothing is known ofits ecology.
