description: 412. Manenguba White-toothed Shrew <i>Crocidura manengubae</i> <b>French:</b> Crocidure du Manengouba / <b>German:</b> Manenguba-WeiRzahnspitzmaus / <b>Spanish:</b> Musarana de Manenguba <b>Other common names:</b> Manenguba Shrew <b>Taxonomy.</b> Crocidura manengubae Hutter- er, 1982, Lager III, 1800 m, Lake Manenguba, Bamenda Highlands, Cameroon. After M. Eisentraut collected this shrew, it has been considered as subspecies of C. httoralis or C. aff. maurisca. R. Hutterer in 1982 and F. Dieterlen and H. Heim de Balsac in 1979 classified C. manengubae in the C. monax-C. littoralis-C. maurisca group. It has not yet been included in any phylogenetic study to determine its true rela- tionship. Monotypic. <b>Distribution.</b> Endemic to W highlands of Cameroon, where it is known from the Bamenda (Lake Manenguba), Adamaoua, and possibly Yaoundé highlands. The Manenguba White-toothed Shrew might be present at additional montane localities, but surveys are needed to confirm this. <b>Descriptive notes.</b> Head-body 77-87 mm, tail 61-62 mm, ear 9-11 mm, hindfoot 16 mm; weight 13-15 g. Condylo-incisive lengths are 21-5-22 mm. The Manenguba White-toothed Shrew is medium-sized. Without any long hairs on its tail, it is very similar (i.e. uniform dark color, naked tail, greatly extended skull, narrow rostrum, and gracile teeth) to the Naked-tailed White-toothed Shrew (C. lttoralis) and the Kahuzi White-toothed Swamp Shrew (C. stenocephala). Pelage of the Manenguba Whitetoothed Shrew is soft and dense (hair lengths 5-6 mm). Upperparts are medium brown, tinged with russet (hairs are basally two-thirds gray and terminal one-third russet-brown). Ventral pelage is brownish gray, contrasting only slightly with dorsal pelage (basal hairs are gray, with pale brown tips). Forefeet and hindfeet are dark russetbrown. Tail is ¢.76% of head-body length and blackish brown, with no pilosity. Only a few hairs are present on tail root. Skull has extended maxillary region and rostrum. Teeth are gracile, I' is long and hooked, and I’ is medium-sized to wide. <b>Habitat.</b> Primary forests, relict montane forests, and mid-elevation moist forests (at Yaounde) at elevations of 1000-1800 m. At Lake Manenguba (an extinct crater lake), the Manenguba White-toothed Shrew was found in a swamp on the shoreline and in grass and shrub habitats close to the edge of the lake. Forested region on steeply sloping sides of the lake is also the only known habitat of Hartwig’s Soft-furred Mouse (Praomys hartwigi). Other shrews caught there are the African Giant White-toothed Shrew (C. olivieri bueae), Eisentraut’s Mouse Shrew (Myosorex eisentrauti), and the Cameroonian Forest Shrew (Sylvisorex camerunensis). The last two species were also captured in a montane relict forest at 2100 m, where the Manenguba White-toothed Shrew (C. manengubae) might also be expected. It is not present on Mount Oku. <b>Food and Feeding.</b> No information. <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 Vulnerable on The IUCN Red List. The Manenguba White-toothed Shrew is known from only three locations, and its extent of occurrence is less than 20,000 km?®. Its distributionis very fragmented, and there is continuing decline offorest cover. It is probably threatened by habitat loss, logging operations, and conversion on land to agricultural use. There are no direct conservation measures in place. The Manenguba White-toothed Shrew has not been recorded in any protected areas. Additional studies are needed into its distribution, abundance, general ecology, and threats. <b>Bibliography.</b> Dieterlen &amp; Heim de Balsac (1979), Eisentraut (1973), Goodman et al.
