Crocidura orientalis

Status and Conservation. Classified as Least Concern on The IUCN Red List in view of its widespread occurrence in montane forests and secondary habitats. The Oriental White-toothed Shrew is found in high densities in gardens, indicating that it can be tolerant of human disturbance. Present in many protected areas. The eastern form lawuana is geographically much more restricted to a few areas in EastJava and may yet prove to be a distinct species.

Descriptive notes. Head-body 73 - 100 mm, tail 62 - 86 mm, ear 7 mm, hindfoot 14 - 17 - 1 mm; weight 9 - 5 - 18 - 2 g. The Oriental White-toothed Shrew is a medium-sized dark brown shrew with long (over 4 mm mid-dorsum), dense fur. Color slightly lighter ventrally; some individuals have a noticeably browner throat. Ears and feet light brown. Tail cylindrical, brown, comparable in length to head-body, essentially naked, except for very short hairs that leave the scales visible. In nominate, the tail is devoid of the bristle hairs typical of other Javan shrews, including the smaller race lawuana. Typical white ring of bare skin around base oftail is present in most Oriental Whitetoothed Shrews. The smaller Javan Long-tailed White-toothed Shrew (C. abscondita), endemic to West Java, has an even longer tail (significantly longer than its head — body length), holding very sparse bristle hairs near its base, and has grayer fur; the similarsized Thick-tailed White-toothed Shrew (C. brunnea) is browner, with a shorter, more conical tail bearing numerous bristles. Chromosomal complement has 2 n = 38 and FN = 56, with subtelocentric X and submetacentric / metacentric Y chromosomes. Chromosomal complement very similar to those of most other Crocidura from the Sunda Shelf, including the Thick-tailed White-toothed Shrew.
