Nephelomys devius
Template:Use dmy dates Template:Short description Template:Speciesbox
Nephelomys devius, also known as the Talamancan oryzomys,[2] Boquete rice rat,[3] Chiriqui rice rat,[4] or montane rice rat,[5] is a species of rodent in the genus Nephelomys of family Cricetidae.[6] It is found in cloud forest in the highlands of Costa Rica and western Panama.[7][2]
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.[4] 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 Script error: No such module "convert"., the combined length of the tail vertebrae from Script error: No such module "convert"., the hindfoot length from Script error: No such module "convert"., and the skull length from Script error: No such module "convert"..[8]
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,[9] and the fur is somewhat paler.[4] Unlike Transandinomys talamancae, possibly the closest relative of the genus Nephelomys, N. devius apparently lacks preputial glands.[10]
It was originally described, in 1902, as a species of Oryzomys, Oryzomys devius, and considered to be related to O. meridensis.[1] In 1966, it was subsumed into Oryzomys albigularis, as were all other species of this group, but subsequently it was reinstated as a species.[2] 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.[6]
