Marmosops (Sciophanes) bishopi (Pine, 1981)

TYPE MATERIAL AND TYPE LOCALITY: USNM 393535 , the holotype by original designation, consists of the skin and skull of an adult female collected at the base camp of the Royal Geographic Society’s Xavantina-Cachimbo Expedition (12.85° S, 51.77° W; 533 m), 264 km N Xavantina , Mato Grosso state, Brazil .

SYNONYMS: None.

DISTRIBUTION: As currently understood (see Remarks), Marmosops bishopi is known to occur in premontane and lowland rainforest from the eastern foothills of the Andes (below about 1300 m) in Ecuador, Peru, and Bolivia eastward across much of lowland Amazonia. North of the Amazon , the range of this species seems to extend at least as far eastward as the Rio Branco ( Abreu et al., 2017: fig. 5) ; south of the Amazon, the easternmost known occurrence is the type locality in central Brazil (DíazNieto and Voss, 2016: fig. 12) .

REMARKS: For illustrations, an emended description, measurements, and morphological comparisons with closely related species, see Díaz-Nieto and Voss (2016), who associated Marmosops bishopi with other species of the Bishopi Group based on phylogenetic analyses of DNA sequence data previously reported by Díaz-Nieto et al. (2016b). The latter authors recognized six morphologically cryptic, allopatric haplogroups within Marmosops bishopi , but whether these haplogroups are distinct lineages that merit taxonomic recognition is currently unknown.
