Marmosa (Micoureus) rutteri Thomas, 1924

TYPE MATERIAL AND TYPE LOCALITY: BMNH 24.2 .22.67, the holotype by original designation, consists of the skin and skull of an adult male collected at Tushemo (8.60° S, 74.32° W; 225 m) near Masisea , Ucayali department, Peru .

SYNONYMS: None.

DISTRIBUTION: Marmosa rutteri occurs in lowland rainforest (below about 800 m) in southeastern Colombia, eastern Ecuador, eastern Peru, and western Brazil (Voss et al., 2020: fig. 17).

REMARKS: Marmosa rutteri was long treated as a synonym or subspecies of M. germana or M. regina , but it is morphologically and genetically distinct from both ( Voss et al., 2019). Voss et al. (2020) provided a description, tabulated morphometric variation, and discussed the phylogenetic relationships of this widespread species, which they assigned to the Rapposa Group.
