SYNONYMS: fuscogriseus J.A. Allen, 1900; grisescens J.A. Allen, 1901; melantho Thomas, 1923. DISTRIBUTION: Based on sequenced specimens, Philander melanurus occurs in western Ecuador , western and inter-Andean Colombia , and Panama (Voss et al., 2018: fig. 3), but it seems likely that the species’s range also extends northward into Costa Rica , Nicaragua , and possibly Honduras . REMARKS: Morphological traits that distinguish this species from other congeners formerly synonymized with Philander opossum remain to be adequately documented. Phylogenetic analyses of multilocus sequence data (Voss et al., 2018) suggest that this species is the sister taxon of P. vossi , another trans-Andean endemic.
