SYNONYMS: None. DISTRIBUTION: As currently documented by examined specimens, Philander pebas occurs in eastern Ecuador ( Orellana ), eastern Peru ( Loreto , Madre de Dios , Ucayali ), and western Brazil ( Acre , Amazonas), but Voss et al. (2018) speculated that the species might range throughout the várzea landscapes (seasonally inundated by white-water rivers) of western Amazonia, including those in southeastern Colombia , where it is still unknown. REMARKS: A morphological description, illustrations, comparisons with congeneric species, summary statistics for external and craniodental measurements, and analyses of mtDNA sequence data were provided by Voss et al. (2018).
