SPECIES Chilomys instans

Author:Thomas, 1895.
Citation:Ann. Mag. Nat. Hist., ser. 6, 16: 368.
Common Name:Andean Chilomys
Type Locality:Colombia, Cundinamarca Dept., Bogotá region, Hacienda de La Selva, 4600 ft (1402 m).
Distribution:N Andes, from C Ecuador (Musser et al., 1998:106), through C and N Colombia, to W Venezuela (Handley, 1976; Linares, 1998).
Status:IUCN – Lower Risk (lc).
Comments:Osgood (1912) described fumeus (type locality: Colombia, Norte de Santander, Páramo de Tamá) as a species distinct from C. instans; however, Cabrera (1961) relegated it to subspecific status, as also observed by Linares (1998), and the genus has thereafter been viewed as monotypic (e.g., Corbet and Hill, 1991; Honacki et al., 1982; Musser and Carleton, 1993). Osgood’s employment of subspecies was especially robust so that he chose to diagnose fumeus as a species is by itself instructive. In view of the other valid species described from the Páramo de Tamá region (e.g., Oligoryzomys griseolus, Thomasomys hylophilus), the status of fumeus invites another appraisal.
