Malayan White-toothed Shrew

Crocidura malayana View in CoL

French: Crocidure de Malaisie / German: Malaya-Weilszahnspitzmaus / Spanish: Musarana de Malasia

Other common names: Malayan Shrew

Taxonomy. Crocidura malayana H. C. Robison & Kloss, 1911 View in CoL ,

Maxwell's Hill , Perak, Malaysia.

Closely related to C. negligens . Crocidura malayana was treated as a synonym of C. fuliginosa , but it can be distinguished by a series of morphological characters, and a different karyotype, and they have relatively distant phylogenetic positions on the evolutionary tree. The names aagaardi, aoris, klossi, and major represent size

and color variations, and are Ha all synonyms of malayana . Monotypic.

Distribution. Malay Peninsula, including a number of offshore islands. View Figure

Descriptive notes. Head-body 77-102 mm,tail 56-78 mm, hindfoot 13-16 mm. No specific data are available for body weight. Condylo-incisive length 22-4-24-2 mm, tooth row 10-1-10-8 mm. The Malayan White-toothed Shrew is the largest shrew in the Malay Peninsula. External morphology is not very different from that of the Southeast Asian White-toothed Shrew ( C. fuliginosa ) and is characterized by seasonal variation in color. Dorsal pelage is dark rusty iron-gray and ventral pelage gray. Bristle hairs on tail extend ¢.50% of its length. Rostrum and palate are broad. Margin of the palatine between pterygoid processes is rounded. Dental formula for all members of this genus is13/2,C1/0,P1/1,M 3/3 (x2) = 28. Mesostyle of M? is simple or slightly notched. Chromosomal complement has 2n = 38-40 and FN = 62-69.

Habitat. [.owland and montane rainforest at elevations of 50-1500 m.

Food and Feeding. The Malayan White-toothed Shrew is insectivorous. Animals were baited with a mixture of oats, sardine oil, and meat.

Breeding. Interbreeding between the Southeast Asian White-toothed Shrew and the Malayan White-toothed Shrew was not observed during a one-month breeding experiment.

Activity patterns. The Malayan White-toothed Shrew is terrestrial.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The IUCN Red List. The Malayan White-toothed Shrew has an extensive distribution and is the commonest member of its genus in the Malay Peninsula. Its distribution overlaps broadly with human settlement. This species is probably threatened, at least locally, by habitat loss, and human induced habitat degradation.
