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).
