description: <i>Delomys</i> Thomas, 1917. Ann. Mag. Nat. Hist., ser. 8, 20: 196. TYPE SPECIES: <i>Hesperomys dorsalis</i> Hensel, 1872. COMMENTS: Thomasomyine. <i>Delomys</i> has variously stood as a genus (Avila-Pires, 1960b; Gyldenstolpe, 1932; Tate, 1932/) or placed within <i>Thomasomys,</i> with or without formal subgeneric division (Ellerman, 1941; Moojen, 1952; Osgood, 1933d). As remarked by Osgood (1933d), Thomas in part created <i>Delomys</i> to taxonomically underscore the geographic disjunction between thomasomyines in SE Brazil and the diverse radiation of typical <i>Thomasomys</i> in the N Andes (e.g., see Reig, 1986). There are features that unite the forms of <i>Delomys,</i> but decision on its classificatory rank—and that of other SE Brazilian endemics like <i>Wilfredomys, Rhagomys,</i> and <i>Phaenomys —</i> must await broader-based phylogenetic inquiry involving Andean thomasomyines. Number of recognized species listed as four (Moojen, 1952), three (Reig, 1986), two (Ellerman, 1941; Gyldenstolpe, 1932), or one (Corbet and Hill, 1991; Cabrera, 1961), a situation which advises that future list-making would profit from critical specimen examination. Here we recognize two, <i>D. dorsalis</i> and <i>D. sublineatus,</i> following the karyotypic study of Zanchin et al. (1992b). Avila-Pires (1960b) associated <i>Calomys plebejus</i> Winge, 1887, as another form of <i>Delomys;</i> its status with regard to <i>dorsalis</i> and <i>sublineatus</i> warrents clarification.
