Olrog's four-eyed opossum

Olrog's four-eyed opossum (Philander olrogi) is a South American species of opossum endemic to 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] It is considered to be a junior synonym of the common four-eyed opossum by some sources, such as the Mammal Diversity Database.^[6][7]
