Taxonomy. Crocidura tanakae Kuroda, 1938 View in CoL ,
Shohosha , Horigai , Taichusiu (= Xiaopushe, pulijie, Taichung), Taiwan, China.
Crocidura tanakae has been considered a synonym, subspecies, or endemic form of C. attenuata in Taiwan for a long time, but it is supported as a distinct species. Monotypic.
Distribution. C & S China (Sichuan, Chongqing, Yunnan, Guizhou, Hunan,
Guangxi, Guangdong, and Taiwan I), Laos, Vietnam, and Batan and Sabtang Is (N Philippines); it probably has a larger distribution in S China and might occur in Cambodia. View Figure
Descriptive notes. Head—body 69-86 mm,tail 47-63 mm, hindfoot 12-14-5 mm. No specific data are available for body weight. Condylo-incisive lengths are 18-4-21-8 mm, and tooth rows are 7-8-9-6 mm. The Taiwanese Gray White-toothed Shrew is mediumsized and morphologically similar to the Asian Gray White-toothed Shrew (S. attenuata ) but smaller. Dorsal pelage is pale gray, and venteris slightly lighter. Tail is ¢.68% of head-body length, and bristle hairis distributed on first two-thirds of tail. Uppersides of feet are gray. Hindfootis larger and broader, with rounder thenar (plantar) pad and hypothenar pad, which are located close to each other. Braincase is low. Ascending ramusis robust, and coronoid process is well developed and high. There are three upper unicuspids; second is smallest. Chromosomal complement has 2n = 40 and FN = 56.
Habitat. Various habitats including grassland, broadleaf forest, bamboo forest and pasture from the sea level to elevations of ¢.2200 m. The Taiwanese Gray White-toothed Shrew was found sympatrically distributed with the other species of Crocidura .
Food and Feeding. The Taiwanese Gray White-toothed Shrew is insectivorous. In Taiwan, digestive tracts contained a wide variety of invertebrates, oligochaetes, larval and adult insects, and centipedes.
Breeding. Pregnant Taiwanese Gray White-toothed Shrews were found in February, March, and August. Litters have 1-3 young. Breeding might not be seasonal in Taiwan.
Activity patterns. The Taiwanese Gray White-toothed Shrew is considered terrestrial.
Movements, Home range and Social organization. Sex ratio of the Taiwanese Gray White-toothed Shrew is c.1-5:1 (male/female) in Taiwan.
Status and Conservation. Classified as Least Concern on The IUCN Red List. The Taiwanese Gray White-toothed Shrew has a wide distribution, new populations are still being discovered, and it is adapted to various habitats. Overall population is unlikely to be declining.
