Sumatran Shrew-like Mouse

Mus crociduroides

French: Souris de Sumatra / German: Sumatra-Zwergmaus / Spanish: Raton musarana de Sumatra

Taxonomy. Oromys crociduroides H. C. Robinson & Kloss, 1916 ,

“Korinchi Peak, 10,000" [= 3048 m], West Sumatra,” Indo-nesia.

On account of peculiar morphology, pre-viously isolated, along with M. vulcani , in a separate subgenus, Mycteromys . In 1977,

on the basis of skull characters, M. crociduroides was moved by J. T. Marshall to subgenus Coelomys; molecular studies by P. Sourrouille and colleagues in 1995 and H.

Suzuki and K. P. sp in 2012 confirmed this placement, situating M. crociduroides close to M. pahari . Monotypic.

Distribution. Endemic to W Sumatra.

Descriptive notes. Head-body 77-97 mm, tail 111-129 mm, hindfoot 21-23 mm. No specific data are available for body weight. Purplish or steely dorsal colors,silvery gray ventrally. Tail is longer than head-body length and bicolored. Furis soft. Females bear three pairs of mammae.

Habitat. High mountain forest of Sumatra at elevations of 2200-3000 m.

Food and Feeding. Due to its shrew-like morphology (long nose, small eye, and velvet fur) it was suggested that the Sumatran Shrew-like Mouse might forage in litter, ferns and rotten logs, feeding on invertebrates.

Breeding. No information.

Activity patterns. Sumatran Shrew-like Mice are terrestrial and probably nocturnal.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Data Deficient on The IUCN Red List.
