Hydromys neobritannicus Tate and Archbold 1935
Hydromys neobritannicus Tate and Archbold 1935, Am. Mus . Novit., 803: 8.
Type Locality: Bismarck Arch., New Britain Isl, Wide Bay, Balayang, Bainings.
Vernacular Names: New Britain Water Rat.
Distribution: Endemic to New Britain Isl.
Conservation: IUCN – Vulnerable.
Discussion: Included in H. chrysogaster by Ellerman (1941) and Ziegler (1982 b), but recognized as a New Britain endemic by Flannery and White (1991) and should retain this status until significance of its diagnostic traits can be assessed in a systematic revision of the large-bodied forms of Hydromys, as Tate (1951:236) already noted. Reviewed by Flannery (1995 b).
