Marmosops (Sciophanes) pinheiroi (Pine, 1981)

TYPE MATERIAL AND TYPE LOCALITY: USNM 461459, the holotype by original designation, consists of the skin and skull of an adult female collected at the Serra do Navio (0.98° N, 52.05° W) on the Rio Amapari, Amapá state, Brazil. According to Ferreira et al. (2020), Serra do Navio is on the left bank of the Rio Amapari.

SYNONYMS: None (see Remarks).

DISTRIBUTION: As currently understood (see Remarks), Marmosops pinheiroi is restricted to the Guiana Region (north of the lower Amazon and east of the Rio Negro-Orinoco, where it is known to occur in eastern Venezuela, Guyana, Surinam, French Guiana, and northern Brazil (Amapá, Roraima, and northern Pará). No published range map shows all the localities from which this species is now known, and some include erroneous records. Díaz-Nieto and Voss’s (2016: fig, 10) map, for example lacks the localities in Amapá, Roraima, and northern Pará reported by Silva et al. (2013), Rossi et al. (2016), and Ferreira et al. (2020), and it includes several localities south of the Amazon that were based on specimens of M. woodalli (but see below). By contrast, Ferreira et al.’s (2020: fig. 5) map does not include any non-Brazilian localities.

REMARKS: Ferreira et al. (2020) provided an emended description of Marmosops pinheiroi as well as illustrations, measurement data, and morphological comparisons with closely related taxa (including M. woodalli , previously treated as a junior synonym; see below). Marmosops pinheiroi was assigned to the Parvidens Group by Díaz-Nieto and Voss (2016) based on phylogenetic analyses of DNA sequence data previously reported by Díaz-Nieto et al. (2016b).
