Olrog's four-eyed opossum (Philander olrogi) is a South American species of opossum found in eastern Bolivia,[1] first described in 2008 based on specimens collected in 1974.[2] It inhabits the lowland Amazon rainforest, with an elevation range of 150 to 250 m.[1] The species is named after Swedish-Argentine biologist Claes C. Olrog.[2][3][4] It is sympatric with P. opossum, which it resembles.[2] The two species differ in several ways, such as ventral fur color and condition of the zygomatic arch.[5]
