description: 275. Vietnamese White-toothed Shrew <i>Crocidura guy</i> <b>French:</b> Crocidure de Guy / <b>German:</b> Vietnam-Weil3zahnspitzmaus / <b>Spanish:</b> Musarana de Vietnam <b>Taxonomy.</b> Crocidura guy Jenkins, Lunde, Moncrieff, 2009, Na Hang Nature Reserve, 300-800 m, Tat Ke Sector, Tuyen Quang Province, Vietnam. Crocidura guy is known only from the type series (four specimens), and its phylogenetic relationships have not been determined. Monotypic. <b>Distribution.</b> Known only from the type locality in Tuyen Quang Province, N Vietnam. <b>Descriptive notes.</b> Head-body 47-53 mm, tail 34-37-5 mm, ear 6-7 mm, hindfoot 9-10 mm. No specific data are available for body weight. Condylo-incisive lengths are 15-3-15-4 mm. The Vietnamese White-toothed Shrew is very small, within the same size group as other small shrews from Vietnam (Annamite White-toothed Shrew, C. annamitensis, Ke Go White-toothed Shrew, C. kegoensis; and Zaitsev'’s White-toothed Shrew, C. zaitsevi). Dorsal pelage of the Vietnamese White-toothed Shrew is brownish gray; individual hairs have gray bases and brown tips. Underpart is silvery gray; hairs have gray bases and light gray and buffy gray tips. There is no demarcation between dorsum and venter. Tail is pale brown dorsally, paler ventrally, and moderately stout, with bristle hairs on proximal one-half. Feet are pale brown, with slightly darker stripe on outer lateral surfaces. Food pads are small and rounded. Males have prominent lateral glands, with central part of short brown hair surrounded by longersilvery hair. Skull is moderately broad, and rostrum is deep. Interorbital region is moderately straight, increasing gradually in breath from anterior to posterior. Braincase is narrow to moderately broad, somewhat flat in profile. Compared with other small shrews from Vietnam, Zaitsev’s White-toothed Shrew is grayer above and the Ke Go White-toothed Shrew and the Annamite White-toothed Shrew are browner. Unlike those three species, the Vietnamese White-toothed Shrew is unique in having silvery gray venter. The Hainan White-toothed shrew (C. wuchihensis) might overlap in some measurements, but on average, the Vietnamese White-toothed Shrew is smaller in external and cranial measurements and has shorter skull. Its pelage is considerably darker grayish brown than the Vietnamese White-toothed Shrew. Tail is 68-77% of head-body length and similar in length Zaitsev’s White-toothed Shrew (61-81%) but unlike shorter tail of the Annamite White-toothed Shrew (57-61%) and the Ke Go White-toothed Shrew (c.56%). Females have three pairs of inguinal mammae. <b>Habitat.</b> Forest and land cleared for cultivation in rugged limestone hills in the Viet Bac karst formation at elevations of 300-800 m. Daovantien’s Limestone Rat (Tonkinomys daovantieni) was recently described in this area. <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 Vietnamese Whitetoothed Shrew is probably not currently at risk. It was found in Na Hang Nature Reserve, which is one of the highest valued biodiversity ecosystems in the world. <b>Bibliography.</b> Abramov etal. (2013), Jenkins, Abramovetal.
