Discussion: Thomasomyini. A speciose and taxonomically complex genus whose nomenclatural history is intertwined with Aepeomys , Delomys , and Wilfredomys , taxa that have been used as subgenera (e.g., Ellerman, 1941; Cabrera, 1961) or as genera (see their accounts). Comparative anatomical studies involving some Thomasomys include Carleton (1973), Hooper and Musser (1964 a), and Voss and Linzey (1981); chromosomal numbers of several species published by Gardner and Patton (1976), Gómez-Laverde et al. (1997), and Aguilera et al. (2000). Based on 6-7 species surveyed, sister genus to Chilomys according to phylogenetic interpretations of mitochondrial DNA sequences (D’Elía et al., 2003; Smith and Patton, 1999). Revisionary studies required to critically overhaul species taxonomy and to place ranking of genus-group taxa in a phylogenetic context. Lacking a current revisionary standard, species recognized here basically follow Cabrera (1961), supplemented by our own museum examinations and subsequent descriptions.
