Niviventer lepturus (Jentink 1879)

[Niviventer] lepturus (Jentink 1879), Notes Leyden Mus ., 2: 17.

Type Locality: Indonesia, W Java, Gunung Gede.

Vernacular Names: Montane Javan Niviventer.

Synonyms: Niviventer fredericae (Sody 1931); Niviventer maculipectus (Sody 1934) .

Distribution: Endemic to montane forest in W and C Java (based upon specimens in AMNH, BMNH, MVZ, RMBR, and RMNH).

Conservation: IUCN – Lower Risk (lc).

Discussion: Reviewed and compared with other species of Niviventer by Musser (1981 b). Originally described as a species, subsequently kept that way in a " lepturus Group" by Ellerman (1941:197), then arranged as a subspecies of rapit (Chasen, 1940; Sody, 1941), and finally recognized again as a separate species and distinctive member of the endemic Javan murine fauna (Corbet and Hill, 1992; Musser, 1986; Musser and Newcomb, 1983; see account of Kadarsanomys sodyi). Multivariate analyses of morphometric traits cluster N. lepturus with the Taiwanese N. culturatus, Chinese N. andersoni and N. excelsior, and Burmese N. brahma, and not with any of the other species of Niviventer occurring on the Sunda Shelf (Musser and Lunde, ms).
