Pinheiro's slender opossum (Marmosops pinheiroi) is an opossum species from South America. It is found in Brazil, French Guiana, Guyana, Suriname and Venezuela.
Opossums are members of the marsupial order Didelphimorphia endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 126 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America.
The Chacoan pygmy opossum is a recently described genus and species of didelphimorph marsupial. The only species in Chacodelphys, C. formosa, was known until 2004 from only one specimen collected in 1920 in the Chaco of Formosa Province, Argentina. The species is gaining popularity as a pocket pet.
The delicate slender opossum is a small pouchless marsupial of the family Didelphidae that occurs in French Guiana, Guyana, Suriname, and adjacent Venezuela and Brazil. Marmosops pinheiroi, Marmosops bishopi and Marmosops juninensis had long been considered to represent the same species, until parvidens and pinheiroi were found in sympatry in French Guiana. This species is found in moist primary tropical rainforest at elevations up to 2000 m. It is nocturnal and partially arboreal, and feeds on insects and fruit.
Tschudi's slender opossum is an opossum species from South America, named after Swiss naturalist Johann Jakob von Tschudi. It is found in Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru and Venezuela.
The gray slender opossum, is an opossum species endemic to eastern Brazil.
The neblina slender opossum is an opossum species from South America. It is found in Brazil, Ecuador, Venezuela, and perhaps Peru.
The white-bellied slender opossum is a species of opossum from South America. It is found in Bolivia, Brazil, Ecuador and Peru.
The Brazilian slender opossum is an opossum species from South America. It is found in moist montane forest in the Atlantic Forest region of southeastern Brazil, including the states of Minas Gerais, Rio de Janeiro, São Paulo and Paraná. Its breeding may be fully semelparous, which is unusual for a mammal.
Marmosops is a genus of Neotropical opossums of the family Didelphidae. The genus was originally treated as a subgenus from the genus Marmosa rather than having their own classification. This was changed in 1989 by Gardner and Crieghton, who officially separated the group and made them their own genus. The mix-up between to genera Marmosa and Marmosops was common due to the similar appearances including size and other external features. However, the two groups differ significantly in their integument and in the arrangement of their skull and dentition. The dentition is similar in morphology between the two groups, with the exception of the deciduous lower third premolar varying from one genus to the next. The similarity between the two continues to cause the genus Marmosops to be frequently misidentified due to the lack of knowledge regarding the species along with the overlooked traits that help separate them from other opossums. The Marmosops are also commonly confused with the genus Gracilinanus, but this is quickly ruled out by a large number of differing characteristics. These differences include the arrangement of their digits, caudal scales, and the central hair on the scales changing from a three hairs per follicle to many more. This causes the hair of the Gracilinanus to be thicker and has also found to be heavily pigmented. The last group commonly confused with Marmosops is known as the genus Thylamys. These animals have a contrasting dorsal body pelage and the taxa are actually quite different.
The narrow-headed slender opossum is a species of opossum in the family Didelphidae. It is endemic to Venezuela.

The Panama slender opossum, also known as the slaty slender mouse opossum, is a species of opossum in the family Didelphidae. It is endemic to Panama, where it has been found in tropical rainforest habitats, including disturbed areas, at elevations from 500 to 1500 m. This opossum is mostly terrestrial in its habits, and feeds on plants and insects. It is vulnerable to deforestation.
Bishop's slender opossum is a small, arboreal marsupial opossum native to Brazil, Peru, and Bolivia. It somewhat resembles a placental rat or shrew.
Creighton's slender opossum, also known commonly as Voss' slender opossum is a species of South American opossum of the family Didelphidae. It is known only from the valley of the Rio Zongo in La Paz Department, Bolivia, where it lives in Andean cloud forests at elevations between 1800 and 3000 m. It was named after G. Ken Creighton by fellow American zoologist Robert S. Voss.
The Junin slender opossum is a species of South American opossum in the family Didelphidae. It is known only from the valley of the Chanchamayu in Peru where it lives in Andean montane forests at elevations between 1460 and 2200 m. The species is threatened by destruction of its forest habitat as the area under cultivation in the region increases.
