Marmosops Matschie, 1916

Species of Marmosops superficially resemble species of Marmosa , but external and craniodental traits that distinguish these distantly related taxa—first recognized as separate genera by Gardner and Creighton (1989) —were described and illustrated by Voss et al. (2004). Subsequent phylogenetic research revealed a deep dichotomy in the genus that was recently formalized by subgeneric nomenclature (Díaz-Nieto et al., 2016). Of the three species definitely known to occur in the Yavarí-Ucayali interfluve, two belong to the nominotypical subgenus and the other to the subgenus Sciophanes ; each is easily distinguished from the others by size and qualitative characters (table 23). A fourth species, apparently associ-
