Gracilinanus agilis (Burmeister, 1854)

Gracilinanus agilis (Burmeister, 1854) View in CoL

TYPE MATERIAL AND TYPE LOCALITY: IZH M-27, the holotype by monotypy, consists of the mounted skin and extracted skull of a young adult male collected at Lagoa Santa ( 19.63° S, 43.82° W), Minas Gerais state, Brazil.

SYNONYMS: beatrix Thomas, 1910; blaseri Miranda-Ribeiro, 1936; rondoni MirandaRibeiro, 1936.

DISTRIBUTION: Gracilinanus agilis occurs in gallery forests and other woody formations of the Cerrado and Caatinga in northeastern and central Brazil ( Bahia, Ceará, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Pernambuco, Piauí) and eastern Bolivia ( Santa Cruz); it also occurs in subtropical forests in eastern Paraguay ( Caazapá, Canindeyú, Cordillera, Paraguarí). No published range map adequately represents the distribution of this species: Creighton and Gardner’s (2008 b) map includes records based on specimens now known to represent G. peruanus , whereas the maps in Costa et al. (2003), Faria et al. (2013b), and Semedo et al. (2015) only show collection localities of sequenced Brazilian material.

REMARKS: Illustrations, measurements, and morphological comparisons with other congeners are in Costa et al. (2003), Geise and Astúa (2009), Lóss et al. (2011), and Semedo et al. (2015). Gracilinanus peruanus was listed as a synonym of G. agilis by Creighton and Gardner (2008 b), but these nonsister taxa are genetically and morphologically distinct, and they are known to occur sympatrically ( Semedo et al. 2015). Phylogenetic analysis of at least one taxon-dense multilocus dataset provides reasonably strong support for G. agilis as the sister taxon of G. microtarsus ( Díaz-Nieto et al., 2016a) .
