Tryphomys Miller, 1910. Proc. U.S. Natl. Mus., 38:399. TYPE SPECIES: Tryphomys adustus Miller, 1910. COMMENTS: Musser and Newcomb (1983) and Musser and Heaney (1992) revised the genus and documented the history of incorrect association of Tryphomys with Rattus. Treated as a Philippine New Endemic by Musser and Heaney (1992). Tryphomys and Abditomys, another Luzon endemic, form a monophyletic cluster; the nature of their phylogenetic alliances to other genera of Philippine New Endemics, or to genera native to other regions in the Indo-Australian region, remains unresolved.
