Chironectes agyrodytes [Salvadoran Water Opossum]
× Chironectes panamensis [Panama Water Opossum] Because probable hybrids were found in Costa Rica, Dickey (1928) lumped two populations (agyrodytes, panamensis) formerly treated as separate species. Both are now usually treated as subspecies of Chironectes minimus.

Didelphis albiventris [White-eared Opossum]
× Didelphis marsupialis [Southern Opossum] These very similar opossums have parapatric and altitudinal contact zones in South America, but it seems no hybrids have as yet been reported (although parental types are so similar in their external appearance that hybrids would be hard to identify). In northern South America D. albiventris replaces D. marsupialis above 2000 meters. Eisenberg 1989; Eisenberg and Redford 1999.
