Discussion: Phloeomys Division. A Philippine Old Endemic in the same monophyletic group as Batomys and Carpomys (Musser and Heaney, 1992) . Reviewed by Musser and Gordon (1981) and Musser et al. (1985). Phylogenetic analyses of complete mtDNA cytochrome b sequences for 13 of the 16 genera of endemic Philippine murines indicates Crateromys belongs in a clade with Batomys and Phloeomys (Jansa and Heaney, 2001) . The tie to Phloeomys was suggested an an alternative hypothesis by Musser and Heaney (1992). Except for the phylogenetic link to Phloeomys, no data supports a close relationship between Crateromys and Coryphomys, Lenomys, Pogonomys, Chiruromys, Chiropodomys, and Mallomys, which, along with Crateromys and Phloeomys, were brought together in the Phloeomyinae by Tate (1936), an arrangement followed by Simpson (1945). Placed by Misonne (1969) in a Lenothrix Group of a more inclusive Lenothrix-Parapodemus Division, and in a Batomys Section of a larger Micromys Group by Pavlinov et al. (1995 a). Actual distribution in the archipelago and number of species in the genus have yet to be determined.
