SYNONYMS: None. DISTRIBUTION: Marmosa zeledoni is known from widely scattered localities, mostly in premontane or montane rainforest (to 2200 m ) but sometimes in very wet lowland forests, from north-central Nicaragua southward through Costa Rica and Panama to western Colombia and northwestern Ecuador ( Rossi et al., 2010 : fig. 21). REMARKS: See Rossi et al. (2010) for an emended description, tabulated measurement data, and morphological comparisons with congeneric species. Marmosa zeledoni was long regarded as a synonym or subspecies of M. mexicana (e.g., by Tate, 1933 ), but these are morphologically and genetically distinct taxa that are known to occur sympatrically at several localities ( Rossi et al., 2010 ; Gutiérrez et al., 2010 ).
