Discussion: Micromys Division. Revised by Musser (1979). Among Asian murines, phylogenetic position of Chiropodomys is ambiguous. Musser and Newcomb (1983) postulated a phylogenetic link between Chiropodomys and Hapalomys , which was also indicated by Misonne (1969) and Chaimanee (1998) based upon molar occlusal patterns, and a weaker tie to Haeromys . Ellerman (1949 a;132) saw a "close relationship" between Chiropodomys and Vandeleuria . Spermatozoal morphology of Chiropodomys resembles that described for species of Hapalomys , Maxomys , and Haeromys , and is also similar to Mus ( Breed and Musser, 1991; Breed and Yong, 1986). Musser (1979) and Musser and Newcomb (1983) recorded other published opinions about relationships of Chiropodomys . No data supports the inclusion of Chiropodomys within the Phloeomyinae along with Coryphomys , Lenomys , Pogonomys , Chiruromys , Mallomys , Phloeomys , and Crateromys , which is where Tate (1936) and Simpson (1945) listed it ( Ellerman, 1949 a:132; our studies).

Evolutionary history of Chiropodomys has been confined to the Indomalayan region (as defined by Corbet and Hill, 1992). The genus extends back to late Pliocene in S China where C. primitivus has been described from isolated molars recovered from cave sediments in the Sichuan-Guizhou region ( Zheng, 1993), and C. gliroides is represented by molars from middle or late Pleistocene cave layers in Guangxi Province of S China ( Chen et al., 2002). In Thailand, the extant C. gliroides is recorded back to late Pliocene, and the extinct C. maximus is represented by isolated molars from middle Pleistocene deposits ( Chaimanee, 1998). On the Sunda Shelf, C. gliroides has been identified from isolated molars recovered from early Pleistocene beds on Java ( Van der Meulen and Musser, 1999) .
