Descriptive notes. Head-body 23.5-29.1 cm, tail 26-30.7 cm; weight 284-550 g. Olrog’s Four-eyed Opossum has fuscous black or dark grayish dorsal fur, with body sides cream buff. Head is darker than dorsum, blackish with well-defined cream-colored supraocular spots, cream-colored cheeks, and no mid-rostral stripe. Tail length is c.110% of head-body length, tail has fur on its proximal 20%, and naked part of tail is bicolored, blackish brown on proximal 75% and cream buff on the rest. Ventral fur is buffy ocher, extending to chin and throat. Fur is short. Forelimbs are creamy-buff, forefeet are brown, hindlimbs are creamybuff anteriorly and black or dark gray, like dorsum, posteriorly, and hindfeet are buffy ocher. Ears are dark and rounded, bicolored, buffy ocher basally and black distally, with no yellow hairs at their posterior base. Females have a pouch, but number of mammae is unknown. Karyotype of Olrog’s Four-eyed Opossum is unknown.

Habitat. L.owland Amazonian forests. The type and paratype of Olrog’s Four-eyed Opossum were collected on borders of a marshy area near a small lagoon formed by an accumulation of rainwater, surrounded by tall forest with a predominance of palm trees. The specimen collected in Peru was collected in a secondary forest area.

Status and Conservation. Classified as Data Deficient on The IUCN Red List. Olrog’s Four-eyed Opossum is known only from very few specimens collected 30-40 years ago, and there is virtually no information on its status, population size, and habitat requirements. It may be threatened by loss of habitat in Bolivia because expansion of agriculture is causing habitat loss in lowland forests. Olrog’s Four-eyed Opossum probably occurs in Parque Nacional Carrasco and Parque Nacional Amboro, but there are no vouchered records ofits presence in protected areas in Bolivia.
