Coccymys albidens (Tate, 1951) . Bull. Am. Mus. Nat. Hist., 97:286.

TYPE LOCALITY: New Guinea, Irian Jaya, 15 mi N Mt Wilhelmina, Lake Habbema, 3225 m .

DISTRIBUTION: New Guinea, Irian Jaya; known only from the type locality and 9 km NE Lake Habbema, 2800 m.

STATUS: IUCN - Insufficiently known.

COMMENTS: Still represented only by the six specimens in the type series collected in 1938. Originally described as a species of Melomys (Tate, 1951), but its diagnostic traits are unlike those defining species within that genus, and similar to those characterizing ruemmleri . This conclusion reached independently by Flannery (1990b) and Menzies (1990), although neither of them formally allocated albidens and ruemmleri to the same genus.
