Marmosops (Marmosops) paulensis ( Tate, 1931)

TYPE MATERIAL AND TYPE LOCALITY: FMNH 26576 , the holotype by original designation, consists of the skin and skull of a young adult male collected at “Therezopolis” (= Teresópolis: 22.43° S, 42.98° W; ca. 870 m), Rio de Janeiro state, Brazil .

SYNONYMS: None.

DISTRIBUTION: Marmosops paulensis is restricted to premontane and montane tropical and subtropical forests (above about 800 m) in southeastern Brazil (Rio de Janeiro, Minas Gerais, São Paulo, Paraná) (Gardner and Creighton (2008b).

REMARKS: An emended description of Marmosops paulensis together with illustrations, measurement data, and morphological comparisons with sympatric M. incanus were provided by Mustrangi and Patton (1997), who also documented moderately deep divergence between a coastal haplogroup in Rio de Janeiro and São Paulo and an inland haplogroup in Minas Gerais. Phylogenetic analyses of multilocus sequence datasets either recover M. paulensis as the sister taxon to a clade that contains all the Amazonian and Andean members of the nominotypical subgenus ( Díaz-Nieto et al., 2016a, 2016b) or as the sister taxon of M. incanus (see Amador and Giannini. 2016).
