Marmosops (Sciophanes) parvidens ( Tate, 1931) View in CoL

TYPE MATERIAL AND TYPE LOCALITY: FMNH 18545 View Materials , the holotype by original designation, consists of the skin and skull of an adult female collected at Hyde Park (6.50° N, 58.27° W; near sea level), on the Demerara River about 35 km S Georgetown, East Demerara –West Coast Berbice region, Guyana GoogleMaps .

SYNONYMS: None.

DISTRIBUTION: Marmosops parvidens occurs throughout northeastern Amazonia (north of the lower Amazon and east of the Rio Negro-Orinoco), including Guyana, Surinam, French Guiana, and Brazil. In Brazil, this species is known from Amapá, northern Pará, and northeastern Amazonas. Díaz-Nieto and Voss’s (2016: fig. 10) map, unfortunately still the best available for this species, does not include the localities in Amapá reported by Silva et al. (2013) nor those from northern Pará reported by Rossi et al. (2016), and it includes an erroneous record from south of the Amazon (see Remarks).

REMARKS: See Díaz-Nieto and Voss (2016) for illustrations, an emended description, measurement data, and morphological comparisons with closely related species. Additional illustrations and comparisons of Marmosops parvidens are in Ferreira et al. (2020), but the small accessory cuspid between the metaconid and entoconid that they attribute to this species is not present in any material that I have seen. Ferreira et al. (2020) questioned the identification of a specimen that Voss et al. (2001) and DíazNieto and Voss (2016) identified as M. parvidens from Ilha do Taiuna on the lower Rio Tocantins (south of the Amazon). I have since reexamined this specimen (AMNH 97333) and determined that it cannot be confidently distinguished from M. woodalli , which is the species expected to occur there based on Ferreira et al’s (2020: fig. 5) range map.
