Oenomys Thomas 1904, Ann. Mag. Nat. Hist., ser. 7, 13: 416.

Type Species: Mus hypoxanthus Pucheran 1855

Species Oenomys hypoxanthus (Pucheran 1855)

Species Oenomys ornatus Thomas 1911

Discussion: Oenomys Division. A phylogenetic analysis of 17 cranial and 23 dental traits related Oenomys most closely to African Thamnomys (Lopez-Martinez et al., 1998), a link previously suggested by Hatt (1940 a), and Lamottemys . A morphometric study using a Fourier analysis applied to outlines of first upper and lower molars underscored the existence of the two species discussed below and the presence of possibly two other undescribed species (Renaud, 1999). DNA/DNA hybridization experiments placed Oenomys in a clade with Arvicanthis, Dasymys, Aethomys, and Hybomys (Chevret, 1994) . Isolated molars of Oenomys have been uncovered from Pliocene and Pleistocene sediments in East Africa (Jaeger, 1976; Sabatier, 1982; Wesselman, 1984; see review by Denys, 1999).
