description: 274. Annamite White-toothed Shrew <i>Crocidura annamitensis</i> <b>French:</b> Crocidure annamite / <b>German:</b> Annam-Weiftzahnspitzmaus / <b>Spanish:</b> Musarana de Annamita <b>Taxonomy.</b> Crocidura annamitensis Jenkins, Lunde &amp; Moncrieff, 2009, Huong Son Camp, 920 m, Huong Son District, Ha Tinh Province, Vietnam. Relationship of Crocidura annamitensis to other shrews is unknown; it needs to be included in a phylogenetic study. Monotypic. <b>Distribution.</b> Known only from the type locality in Huong Son district, Ha Tinh Province, NC Vietnam, at elevations of 920-1240 m; it likely occurs at higher elevations throughout the N Annamite Range and may be expected on bordering Laos. <b>Descriptive notes.</b> Head-body 49-58 mm, tail 30-33 mm, ear 5-8 mm, hindfoot 9-10 mm. No specific data are available for body weight. Condylo-incisive lengths are 15-1-15-4 mm. The Annamite White-toothed Shrew is very small. Its tail is 57-61% of head-body length, similar to the Ke Go White-toothed Shrew (C. kegoensis) but shorter than the 68-77% of the Vietnamese White-toothed Shrew (C. guy). Dorsal pelage is light brown; individual hairs have pale gray bases and pale brown tips. Underparts are grayish buff; individual hairs have grayish brown bases and become buffy toward tips. There is no demarcation between dorsal and ventral color. Tail is dark brown above and pale brown below. Proximal one-half oftail has long pilose hairs. Dorsal surfaces of hands are pale brown, and those on feet are pale buffy brown, with darker lateral pigmentation. Skull is small with narrow rostrum, increasing gradually in breadth through interorbital region and through well-developed braincase such that skull approximates a rather evenly shaped wedge in dorsal view. Skull of the Annamite Whitetoothed Shrew is narrower than that of the Ke Go White-toothed Shrew, which also has a slightly longer braincase. <b>Habitat.</b> Presumably tropical and subtropical moist broadleaf forests. Three species of small shrews—the Annamite White-toothed Shrew, the Taiwanese Gray White-toothed Shrew (C. tanakae), and the Hainan White-toothed Shrew (C. wuchihensis)—occur in Northern Annamite Rainforests Ecoregion 54. <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 IUCN Red List. The Annamite Whitetoothed Shrew is probably not currently at risk. Northern Annamite Range contains large tracts of intact forest. Biogeographically, it is one of three endemic shrews (Annamite White-toothed Shrew; Sokolov’s White-toothed Shrew, C. sokolovi; and Zaitsev’s White-toothed Shrew, C. zaitsevi) from high-elevation localities in the Annamite Mountain chain that supports other endemic mammals such as the Saola (Pseudoryx nghetinhensis) and the Annamite Striped Rabbit (Nesolagus timminsi). <b>Bibliography.</b> Abramov et al.
