''Nephelomys moerex'' is a species of rodent in the genus ''Nephelomys'' of family Cricetidae.〔Weksler et al., 2006, p. 18〕 The type locality is at Mindo in western Ecuador,〔Ellerman, 1941, p. 349〕 where it has been recorded together with three other rodents of the oryzomyine group, ''Sigmodontomys aphrastus'', ''Mindomys hammondi'', and ''Handleyomys alfaroi'', as well as three opossums, ''Chironectes minimus'' and unidentified species of ''Didelphis'' and ''Marmosa''.〔McCain et al., 2007, p. 132〕 Mindo is a "tiny agricultural community"〔Weksler et al., 2006, p. 19〕 located at 0°02'S, 78°48'W and above sea level. It was originally described by Oldfield Thomas as a subspecies of ''Oryzomys albigularis''. It remained synonymized under this species〔Musser and Carleton, 2005, p. 1145〕 until it was recognized as a separate species when the genus ''Nephelomys'' was established for ''Oryzomys albigularis'' and related species in 2006.〔 Unlike in the type species of the genus, ''N. albigularis'', the lacrimal bone of the skull is connected primarily to the maxillary bone, not equally to the maxillary and frontal bones. The incisive foramina, perforations in the palate between the incisors and the molars, are shorter than in some other ''Nephelomys'' species, not extending between the molars, and closer to the molars they are wider than further to the front, also unlike in some other species of the genus.〔 These foramina are similar in shape to those in ''N. nimbosus''.〔Anthony, 1926, p. 5〕 The alisphenoid strut, an extension of the alisphenoid bone of the skull which separates two openings in the skull, the buccinator–masticatory foramen and the accessory oval foramen, is usually present, although it is more commonly absent in other ''Nephelomys''.〔Weksler et al., 2006, p. 19〕 ==References==
