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 ).
