Abstract. A new species of Crocidura is described from the Ke Go Nature Reserve in Ha Tinh Province, Vietnam. Its small body size and conspicuous brownish black mystacial patches on the muzzle above the upper lips readily distinguish it from the three species of Crocidura commonly reported from Vietnam: C. fuliginosa, C. attenuata and C. indochinensis (formerly C. horsfieldii indochinensis). In body size, the Ke Go most closely resembles another crocidurine, C. wuchihensis, which was originally described as a subspecies of C. horsfieldii from Hainan Island, China, but has recently been identified as a separate species also occurring in Vietnam. The new species can be separated from C. wuchihensis by its smaller body size, certain shorter cranial and dental dimensions (condylo-basal and braincase lengths, incisor to third length, upper toothrow length) and deeply emarginate posterior border of the last premolar and each molar. Known only from the holotype, the discovery of the new Crocidura underscores our meager knowledge of Vietnamese Soricomorpha diversity and the need for continued surveys of small in remnant lowland and mountain forests within the country.

(2003) recently suggested that the (Jiang and Hoffmann 2001; Motokawa et al. 2003) and name horsfieldii is better restricted to populations from C. monticola (HB 40–68; T 30–55) in Indonesia south of Sri Lanka and peninsular India, with C. indochinensis the Isthmus of Kra (Davison et al. 1982; Jenkins 1982; 30 Mammal Study 29 (2004)

Davison 1984; Ruedi 1995). However, the distributions of both C. shantungensis and C. monticola are separated from Vietnam by considerable geographic gaps (Jenkins 1982; Jiang and Hoffmann 2001) and each is readily dis- tinguished from the Ke Go Crocidura morphologically: Crocidura shantungensis has a sharply bicolored tail which is very hairy and has bristles along its entire length (Jiang and Hoffmann 2001), while C. monticola is dis- tinguished by its longer tail and high, domed braincase (Davison et al. 1982; Jenkins 1982; Davison 1984; Ruedi 1995). The only Crocidura of small body size that requires comparison with the Ke Go Crocidura is C. wuchihensis. Originally described as a subspecies of C. horsfieldii from Hainan Island (by Wang, in Shaw et al. 1966), wuchihensis was listed that way by Corbet and Hill (1992), but is now regarded as a valid species from Vietnam (Lunde et al. 2003); it is with C. wuchihensis that we restrict our comparisons when describing the Ke Go Crocidura.

These differences and the smaller size and narrower cranium of Suncus etruscus allow for the ready distinction of the two.

Etymology: The specific name refers to the type local- ity lying within the Ke Go Nature Reserve, which was named for Lake Ke Go (Vietnamese: “Ho Ke Go”) in the south of Ha Tinh Province (Le et al. 1999; Ziegler 2002); the scientific name emphasizes the importance Fig. 7.
