Echiothrix centrosa Miller and Hollister 1921

Echiothrix centrosa Miller and Hollister 1921, Proc. Biol. Soc. Wash., 34: 67.

Type Locality: Indonesia, C Sulawesi, Winatu (01E34' S, 119E59' E), 2500 ft (760 m).

Vernacular Names: Central Sulawesi Echiothrix.

Synonyms: Echiothrix brevicula Miller and Hollister 1921 .

Distribution: Sulawesi: NC portion of N peninsula and central core of islands, sea level to 975 m in lowland tropical evergreen rainforest; southern limits unknown.

Discussion: A distinct species distinguished from E. leucura by its shorter cranium and mandible, and shorter molar rows with simpler occlusal patterns. The pelage coloration and size features used by Miller and Hollister (1921 a) to distinguish brevicula, which is also based upon a sample from C Sulawesi, are not diagnostic. The derived karyotype of male documented by Musser (1990, as leucurus): 2n = 40, FN = 75, consisting of two telocentric pairs, three metacentric pairs, and the rest submetacentric. Stomach morphology described and contrasted with the Sulawesian shrew rats Melasmothrix and Tateomys, and the insectivorous Sommeromys (Musser and Durden, 2002) .
