Nephelomys auriventer és una espècie de rosegador de la família dels cricètids. Viu a altituds d'entre 1.140 i 1.660 msnm a l'Equador i el Perú. Els seus hàbitats naturals són els boscos primaris, els boscos secundaris, els camps de conreu i la vegetació subtropical. Es desconeix si hi ha alguna amenaça significativa per a la supervivència d'aquesta espècie.[1]

Nephelomys auriventer, also known as the golden-bellied oryzomys[2] or Ecuadorian rice rat,[1] is a species of rodent in the genus Nephelomys of family Cricetidae.[3] Oldfield Thomas originally described it, in 1899,[4] as a species of Oryzomys, Oryzomys auriventer, and considered it most similar to Oryzomys aureus (currently Thomasomys aureus).[5] In 1926, a subspecies was described from an Ecuadorian locality, Oryzomys auriventer nimbosus, and it was suggested that O. auriventer was closely related to O. albigularis.[6] This proposal was formalized in 1961 by including O. auriventer within the species O. albigularis, but by 1976 O. auriventer was recognized again as a separate species.[2] In 2006, Oryzomys albigularis and related species, including O. auriventer, were transferred to the new genus Nephelomys. Simultaneously, the former subspecies nimbosus was recognized as a separate species, Nephelomys nimbosus.[3]
N. auriventer is a fairly large species, though it is somewhat smaller than the black rat (Rattus rattus). It has fine, not woolly fur which is about 10 millimetres (0.39 in) in length at the back. The upperparts are blackish, becoming lighter towards the sides.[7] The coloration of the upperparts is sharply divided from that of the underparts, which is ochraceous. The large ears are brown. The tail is long and almost lacks hairs; it is dark brown above and slightly lighter below. The holotype, an old male, has head and body length 147 millimetres (5.79 in), tail length 160 millimetres (6.30 in), hindfoot length (without claws) 35 millimetres (1.38 in) and ear length 23 millimetres (0.91 in).[5]
The form of the interorbital region of the skull is distinctive, featuring distinctly beaded margins that converge towards the front. Unusually for a Nephelomys, the jugal bone of the skull is large. The alisphenoid strut, an extension of the alisphenoid bone of the skull which separates two openings in the skull, is sometimes present. The subsquamosal fenestra, an opening in the posterior part of the skull, is relatively small. The mastoid bone is completely ossified, lacking the openings that are present in most species of the genus.[8]
It is found in eastern Ecuador and northern Peru on the eastern slope of the Andes at elevations from 1000 to 2900 m. It is uncommon in Ecuador, and so far it has been found in only one locality in Peru, far to the south of its Ecuadorian range. It occurs in páramo and a variety of forest habitats.[1]

Nephelomys auriventer är en däggdjursart som beskrevs av Thomas 1890. Nephelomys auriventer ingår i släktet Nephelomys och familjen hamsterartade gnagare.[4][5] Inga underarter finns listade i Catalogue of Life.[4]
Arten förekommer främst i Anderna i Ecuador. En mindre avskild population hittades i centrala Peru. Nephelomys auriventer lever i regioner som ligger 1100 till 2900 meter över havet. Gnagaren vistas i landskap Páramo samt i skogar.[1]

에콰도르쌀쥐[1] 또는 황금배쌀쥐[2](Nephelomys auriventer)는 비단털쥐과 톰스쌀쥐속에 속하는 설치류이다.[3] 1899년 토마스(Oldfield Thomas)가 학명 Oryzomys auriventer로써 쌀쥐속에 속하는 종으로 처음 기술했고,[1] 황금올드필드쥐(Oryzomys aureus, 현재 Thomasomys aureus)와 가장 유사한 종으로 간주했다.[4]
