''Nephelomys devius'', also known as the Talamancan oryzomys,〔Musser and Carleton, 2005〕 Boquete rice rat,〔Reid and Samudio, 2008; Goldman, 1920, p. 99〕 Chiriqui rice rat,〔Goldman, 1918, p. 80〕 or montane rice rat,〔Duff and Lawson, 2004〕 is a species of rodent in the genus ''Nephelomys'' of family Cricetidae.〔Weksler et al., 2006, p. 18〕 It is found in cloud forest in the highlands of Costa Rica and western Panama.〔〔 The upperparts are light brown and become lighter towards the sides. The underparts are buffy or dull white, with a whitish area at the throat. The ears are blackish, as is the nose, and the feet are yellow to brown.〔 The tail is dark brown above and somewhat lighter below. In juveniles, the fur of the upperparts is darker. In three specimens, the total length ranges from , the combined length of the tail vertebrae from , the hindfoot length from , and the skull length from .〔Goldman, 1918, p. 81〕 ''N. devius'' is the westernmost representative of its genus, with a related species, ''N. pirrensis'', known from eastern Panama. In contrast to that species, the chest region is marked by a white patch, as in various other ''Nephelomys'' species. The skull is more rounded, the auditory bullae are larger,〔Goldman, 1920, p. 99〕 and the fur is somewhat paler.〔 Unlike ''Transandinomys talamancae'', possibly the closest relative of the genus ''Nephelomys'', ''N. devius'' apparently lacks preputial glands.〔Weksler et al., 2006, p. 21〕 It was originally described, in 1902, as a species of ''Oryzomys'', ''Oryzomys devius'', and considered to be related to ''O. meridensis''.〔Bangs, 1902, p. 34〕 In 1966, it was subsumed into ''Oryzomys albigularis'', as were all other species of this group, but subsequently it was reinstated as a species.〔 In 2006, members of the ''O. albigularis'' group were transferred into a new genus, ''Nephelomys''; since then, the species has been known as ''Nephelomys devius''.〔 ==References==
