Gracilinanus emiliae (Thomas, 1909)

TYPE MATERIAL AND TYPE LOCALITY: BMNH

9.3.9.10, the holotype by original designation,

consists of the skin and skull of a subadult male collected at “Para” (= Belém: 1.45° S, 48.48° W), Pará state, Brazil.

SYNONYMS: longicaudus Hershkovitz, 1992.

DISTRIBUTION: Gracilinanus emiliae is known from fewer than 20 localities, but these are widely scattered across cis-Andean tropical South America, mostly in Amazonian rainforest, but also in northern Venezuela, at the northern margin of the Cerrado, and at the western edge of the Llanos ( Brandão et al., 2014: fig. 3).

REMARKS: See Voss et al. (2001, 2009b) for emended descriptions, illustrations, measurements, and morphological comparisons with other congeners; additional illustrations, measurements, and morphological observations are in Brandão et al. (2014). Phylogenetic analyses of taxon-dense multilocus datasets suggest that Gracilinanus emiliae is the sister species of G. marica , and that this pair is the sister group of a larger clade that includes all the other species in the genus ( Díaz-Nieto et al., 2016a; Teta and Díaz-Nieto, 2019).
