Indochinese White-toothed Shrew
Crocidura indochinensis View in CoL
French: Crocidure d'Indochine / German: Indochina-Weifdzahnspitzmaus / Spanish: Musarana de Indochina
Other common names: Indochinese Shrew
Taxonomy. Crocidura indochinensis H. C. Robinson & Kloss, 1922 View in CoL ,
Dalat , Langbian Plateau , Vietnam.
Previously treated as a synonym of C. hors- fieldii, which was considered far more widespread; many of its former subspecies in East Asia including indochinensis and wuchihensis from China have been elevated to full species. The species boundary between these two is not entirely clear. Several populations from Vietnam which
were identified as either indochinensis or wuchihensis have now been recognized as distinct species. C. indochinensis may still include undescribed species, and it is not known whether the populations of southern Vietnam are conspecific with those of southern China. Monotypic.
Distribution. Known from SW China (Yunnan and Guizhou), adjacent N & W Myanmar, Laos, Thailand, and S Vietnam. Because both the Indochinese White-toothed Shrew and the Hainan White-toothed Shrew ( C. wuchihensis ) were identified as Horsfield’s White-toothed Shrew (C. horsfieldiz) until recently, their distribution limits in China are not clear.

Descriptive notes. Head-body 53-61 mm, tail 40-50 mm, hindfoot 10-13 mm. No specific data are available for body weight. Condylo-incisive length 17-17-6 mm, and tooth row 7-1-7-5 mm. The Indochinese White-toothed Shrew is a moderately small shrew, intermediate in size between the smaller Hainan White-toothed Shrew and the larger Voracious White-toothed Shrew ( C. vorax ), averaging smaller than the Chinese White-toothed Shrew ( C. rapax ). Pelage dark brownish gray, darker and grayer than in the Chinese White-toothed Shrew. Tail is slender, 63%-85% of head-body length; few bristles on basal part of the tail. Skull is broader than that of the Hainan Whitetoothed Shrew, the maxillary region is broader, interorbital region averages broader and braincase is broader and longer. Upper incisors do not project anteriorly. Third upper unicuspids smaller than the first and larger than the second.
Habitat. In China, the Indochinese White-toothed Shrew inhabits montane broadleaved and coniferous forests at elevations of 1200-2400 m. It occurs in both primary and secondary forests.
Food and Feeding. The Indochinese White-toothed Shrew is insectivorous.
Breeding. No information.
Activity patterns. Terrestrial.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least Concern on The IUCN Red List. There is little information regarding its population. In southern China, it is known to be common in several protected areas. It is not known whether or not it can adapt to anthropogenic habitats.
