A. Allen 1901 Oryzomys bolivaris J. A. Allen 1901 , Bull. Am. Mus . Nat. Hist., 14: 405 . Type Locality: Ecuador , Bolívar Prov. , Porvenir, 1800 m . Vernacular Names: Long-whiskered Oryzomys . Synonyms: Oryzomys alleni Goldman 1915 ; Oryzomys bombycinus Goldman 1912 ; Oryzomys castaneus J. A. Allen 1901 ; Oryzomys orinus Pearson 1939 ; Oryzomys rivularis J. A. Allen 1901 . Distribution: Lowland evergreen to lower montane cloud forest from E Honduras , through E Nicaragua , Costa Rica and Panamá , to W Colombia and WC Ecuador (see Musser et al., 1998:Fig. 50); about sea level to 1800 m . Conservation: IUCN – Lower Risk (lc). Discussion: Names conventionally applied to this species include bombycinus , as reviewed by Pine (1971), and rivularis , as discussed by Gardner and Patton (1976) . Priority of bolivaris established by Musser et al. (1998), who summarized the morphological variation, geographic distribution, and synonymy of the species. Pine (1971) retained subspecies (under the name bombycinus ), but Musser et al. (1998) judged intraspecific variation too insubstantial to circumscribe geographic races.
