Hadromys Thomas, 1911 . J. Bombay Nat. Hist. Soc., 20:999.

TYPE SPECIES: Mus humei Thomas, 1886 .

COMMENTS: Usually considered closely allied to Arvicanthis and its relatives, especially Golunda, but a combination of primitive and derived cranial and dental traits divorces Hadromys from that group: "best hypothesis now available on phylogenetic affinities is to consider the species of Hadromys to have been derived from some late Miocene ancestor, a species of Karnimata, for example" (Musser, 1987:19).
