Mount Malindang White-toothed Shrew
French: Crocidure du Malindang / German: Malindang-WeiRzahnspitzmaus / Spanish: Musarana de Malindang
Other common names: Greater Mindanao Shrew, Mount Malindang Shrew
Taxonomy. Crocidura grandis G. S. Miller, 1910 View in CoL ,
Grand Malindang Mountain, 6100 ft (= 1859 m), Mindanao, Philippines.
In 1992, G. B. Corbet and J. E. Hill treated this form within C. mindorus , but in 1993 and 2005 R. Hutterer listed it as distinct. Crocidura grandis is the only member of Philippine Crocidura , not yet to have been included in a molecular phylogenetic analysis;it is in need of further taxonomic research. Monotypic.
Distribution. Known only from Mt Malindang on Mindanao I, Philippines. View Figure
Descriptive notes. Head-body 100 mm, tail 59 mm, hindfoot 19 mm (all measurements from the type specimen). No specific data are available for body weight. Condylo-incisive length is 23-6 mm. The Mount Malindang White-toothed Shrew is a large shrew, with a moderately long tail (59% of head-body length). It is larger than its congener the Mindanao White-toothed Shrew (C. beata), also of Mindanao. In size, it is comparable with other Philippine Shrews, such as the Mindoro White-toothed Shrew ( C. mindorus ), the Negros White-toothed Shrew ( C. negrina ), and the Palawan Whitetoothed Shrew( C. palawanensis ). Compared to the Mindoro White-toothed Shrew, the tail is thicker with fewer bristle hairs and longer hindfeet; the cranium is more elongate, braincase slightly less globose, interorbital region broader, molars larger (10-1 mm). The Mount Malindang White-toothed Shrew is gray-brown with dark brown feet and tail, similar to the Mindoro White-toothed Shrew. It has a slight slaty tinge all over its pelage.
Habitat. Apparently confined to primary forest at medium to high elevations. Not known whetherit adapts to anthropogenic habitats. Nor is it yet confirmed whether or notit co-occurs with the Mindanao White-toothed Shrew.
Food and Feeding. No information.
Breeding. No information.
Activity patterns. No information.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Data Deficient on The IUCN Red List, as this species is known only from a few specimens. There were no surveys for this species until 2000, but two recent surveys on Mount Malindang found several specimens (five individuals) which might be this species. Surveys have not found it in surrounding regions or on other mountains on Mindanao, which suggests that the species could be confined to Zamboanga Peninsula, and within the range of Mount Malindang, which is the highest point on the Peninsula. There is insufficient information on habitat, range, and threats. There has been extensive deforestation in the region where the species occurs, and most of the lowland forest has been cleared. The effects of deforestation on this species are not known. It occurs within the Mount Malindang National Park, but the park is not well managed and therefore does not afford this species adequate protection.
