SYNONYMS: None. DISTRIBUTION: Caluromysiops irrupta is restricted to lowland Amazonia, where it is known from scattered localities in Brazil ( Mato Grosso , Rondônia ), Colombia (Amazonas), and Peru ( Loreto , Madre de Dios ) ( Santori et al., 2016 : fig. 2). REMARKS: See Voss and Jansa (2009) for illustrations, analyses of phylogenetic relationships and qualitative morphological descriptors. The only published morphometric data for Caluromysiops irrupta are still those in Izor and Pine (1987). Despite several reported sightings and one recent capture (summarized by Santori et al., 2016 ), no new morphological specimens or genetic samples have been obtained for several decades.
