Species Xenomys nelsoni Merriam 1892

Discussion: Neotomini. Retained as a genus since its description. Among woodrats believed to share common ancestry with Hodomys ( Carleton, 1980) ; banded karyotype reported by Haiduk et al. (1988), who noted its resemblance to those of Onychomys and Peromyscus ; restriction-site analyses of mitochrondrial DNA portrayed Xenomys and Ototylomys as a clade basal to nine Neotoma species studied, including N. cinerea (subgenus Teonoma ) and N. phenax (subgenus Teanopus ) ( Planz et al., 1996). Sister-group kinship with Hodomys and generic rank reaffirmed based on broad molecular survey (cytochrome b) of Neotoma species, including N. (Teonoma) cinerea ( Edwards and Bradley, 2002 b) .
