Marmosa (Stegomarmosa) lepida

(Thomas, 1888)

TYPE MATERIAL AND TYPE LOCALITY: BMNH 69.3 .31.4, the holotype by original designation, consists of the skin and skull of an adult female collected at Santa Cruz (5.55° S, 75.80° W; 150 m) on the Río Huallaga , Loreto, Peru .

SYNONYMS: grandis Tate, 1931 (but see Remarks).

DISTRIBUTION: Marmosa lepida probably occurs throughout Amazonia ( Guimarães et al., 2018: fig. 1) and in contiguous premontane forests along the lower slopes of the eastern Andes (below about 1600 m; Brito and PozoZamora, 2015). Although there are some notable gaps among the Amazonian collection localities mapped by Guimarães et al. (2018), one of them is filled by two overlooked records from southern Venezuela: the first is a specimen from the Río Caura reported by Ochoa et al. (2009), and the second is a previously unpublished specimen in the collection of the Estación Biológica Doñana. 6

REMARKS: Rossi (2005) and Voss et al. (2019) provided morphological descriptions and illustrations of this species and tabulated measurement data. Additional phenotypic data are in Guimarães et al (2018). The possibility that grandis, which differs from M. lepida in several morphological features, might be a distinct species was discussed by Voss et al. (2019).
