description: 316. Ivory Coast White-toothed Shrew <i>Crocidura eburnea</i> <b>French:</b> Crocidure de Céte d'Ivoire / <b>German:</b> Elfenbeinklsten-Weiflszahnspitzmaus / <b>Spanish:</b> Musarana de Costa de Marfil <b>Taxonomy.</b> Crocidura bottegi eburnea Heim de Balsac, 1958, Mount Tonkoui, Ivory Coast. Previously included in S. obscurior, as a synonym, but recent phylogenetic and morphological studies have found the two to be sympatric cryptic species that should be recognized as distinct. They are distinct karyologically, but the chromosomal complement is uncertain: either 2n = 40 and FN = 60, or 2n = 36 and FN = 56, as these two combinations were recorded where this species and C. obscurior are sympatric, but the identity of the specimens tested is unknown. There seem to be four major genetic clades that may represent separate subspecies, but further research is needed. Monotypic. <b>Distribution.</b> SE Guinea, E Liberia, and SW Ivory Coast in West Africa; the species may be found in Sierra Leone, but this population has not been genetically investigated and could be either the Ivory Coast White-toothed Shrew or the West African Pygmy White-toothed Shrew (C. obscurior). <b>Descriptive notes.</b> Head-body 52-60 mm,tail 23-31 mm, ear 6 mm, hindfoot 10 mm; weight 3-1-3-8 g. The Ivory Coast White-toothed Shrew is a very small species with short, soft, dense, velvety pelage. Dorsal pelage is dark brown with a slight rufous tinge and a silky sheen; ventral pelage is grayish brown. Ears are darkly pigmented and covered in very short dark hairs, although appearing naked. Tail is relatively long (c.60-70% of head-body length), covered in long white bristle hairs, and bicolored, being dark brown above and slightly paler below. Braincase is high-domed and first upper incisor is long and hooked; braincase is wider and longer than in the West African Pygmy White-toothed Shrew. M” is wide; there are three unicuspids. <b>Habitat.</b> Found primarily in lowland rainforest at elevations up to ¢.600 m. Ecological data for the West African Pygmy White-toothed Shrew may also apply to the Ivory Coast White-toothed Shrew, since they are sympatric and very similar. <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> Not assessed on The [UCN Red List since it is included as a synonym of the West African Pygmy White-toothed Shrew, which is considered Least Concern. The species seems to be relatively common throughoutits wide range and may be locally threatened by logging operations, although there is still considerable confusion as to which species (obscurior or eburnea) applies to what populations. <b>Bibliography.</b> Jacquet et al.
