Tate (1931 , 1933 ) thought that the type was collected in Ecuador , but “Boca Río Curaray” (as this locality was originally recorded by the collectors) is well within the internationally recognized borders of Peru ( Wiley, 2010 ). SYNONYMS: None. DISTRIBUTION: Marmosa rubra is known from just a few localities in the Amazonian lowlands of southeastern Colombia ( Putumayo ), eastern Ecuador ( Napo , Orellana , Pastaza , and Sucumbios ), and eastern Peru ( Loreto , and Madre de Dios ) ( Rossi et al., 2010 : fig. 30). Additional Peruvian records were summarized by Pacheco et al. (2020) . REMARKS: See Rossi et al. (2010) for an emended morphological description, illustrations, measurement data, and comparisons with congeneric species.
