Discussion: Chrotomys Division. Philippine Old Endemic shrew rats unrelated to shrew rats and shrew mice endemic to Australia and New Guinea ( Musser and Heaney, 1992). Phylogenetic analyses of complete mtDNA cytochrome b sequences for 13 of the 16 genera of endemic Philippine murines places Chrotomys (along with Celaenomys ) in the same clade as Apomys , Archboldomys , and Rhynchomys , which are also Old Endemics ( Jansa and Heaney, 2001); karyotypic variation supports this alliance (Rickart and Heaney, 2002). Actual distribution in archipelago and number of species in genus still unknown; an undescribed species has been found in lowland forest on Sibuyan Isl ( Heaney et al., 1999).
