Mindoro White-toothed Shrew
Crocidura mindorus View in CoL
French: Crocidure de Mindoro / German: Mindoro-WeilRzahnspitzmaus / Spanish: Musarana de Mindoro
Other common names: Mindoro Shrew
Taxonomy. Crocidura mindorus G. S. Miller, 1910 View in CoL ,
Mount Halcon , 1938 m, Mindoro , Philippines.
In 1992 G. B. Corbet and J. E. Hill in- cluded C. negrina and C. grandis within C. mindorus, but in 1993 and 2005 R. Hutterer treated them as three distinct species. Previously, the population of Sibuyan Island was assigned to C. mindorus , butit was recently described as the new species C. ninoyi. Phylogenetically the C. mindorus
is either basal to a clade consisting of C. ninoyi, C. negrina , and C. panayensis , or part of a basal polytomy with other species from the Philippines. Monotypic.
Distribution. Known only from high elevations from Mt Halcon, Mindoro I, Philippines. View Figure
Descriptive notes. Head-body 91 mm (type specimen), tail 73-78 mm, hindfoot 17-18 mm; weight c.13-5 g. Condylo-incisive length is 22:3-22-6 mm. In color and general appearance, the Mindoro White-toothed Shrew resembles the Luzon White-toothed Shrew (C. grayi ), but it is noticeably larger. In contrast to the Sibuyan White-toothed Shrew (C. ninoyi), the Negros White-toothed Shrew ( C. negrina ), and the Panay Whitetoothed Shrew ( C. panayensis ), the Mindoro White-toothed Shrew hasa thick tail, with numerous bristle hairs along its entire length. Compared to the Mount Malindang White-toothed Shrew ( C. grandis ), tail is thinner with fewer long hairs on proximal half, hindfeet shorter and heavily pigmented. Cranium is less elongate, and interorbital region slightly narrower. Compared to the Negros White-toothed Shrew, braincase is more globose, interorbital region broader.
Habitat. Little is known about the habitat and ecology of this species, but it may be restricted to high-elevation primary forest. It is known from two specimens taken in 1906 on Mount Halcon at 1920 m, and another taken in 1992 at 1550-1800 m. The other Crocidura on Mindoro is the Luzon White-toothed Shrew, which is common and widespread.
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. More surveys are needed on Mindoro to find new information about the species’ populations, habitat preferences, threats, and conservation requirements. It is not known whether or not it occurs in any protected areas. Mindoro has undergone extensive deforestation, but there is some remaining montane forest.
