Gracilinanus aceramarcae ( Tate, 1931)

TYPE MATERIAL AND TYPE LOCALITY: AMNH 72568 , the holotype by original designation, consists of the skin and skull of a young adult female collected on the Río Aceramarca (16.30° S, 67.88° W; 3292 m), a tributary of the Río Unduavi, in La Paz department, Bolivia .

SYNONYMS: None.

DISTRIBUTION: Gracilinanus aceramarcae has been collected in montane forest at elevations above

2000 m in Peru and northern Bolivia (Creighton and Gardner, 2008 b: map 16). In Peru, this species (or a complex of similar species) is said to be widely distributed, from the department of Piura in the north to Puno in the south ( Pacheco et al., 2020).

REMARKS: See Voss et al. (2009b) and Semedo et al (2015) for morphological comparisons with other congeneric species. The relationships of this species with other congeners are notably inconsistent as recovered by different phylogenetic analyses of DNA sequence data (e.g., Semedo et al., 2015, 2022; Díaz-Nieto et al., 2016a).
