Rogers and Schmidly (1982) revised the desmarestianus group. Hall and Kelson (1959: 543) and Hall (1981: 596) commented on the need for revision of this genus. Rogers (1989, 1990) discussed phylogenetic relationships among species, and remarked on at least one undescribed species from Costa Rica, as did Handley (1976) from Venezuela. Key to the species given in Schmidt et al. (1989).	en	James L. Patton (1993): Order Rodentia - Family Heteromyidae. In: Don E. Wilson, DeeAnn M.
