Lygosoma is a genus of lizards, commonly known as supple skinks or writhing skinks, which are members of the family Scincidae. Lygosoma is the type genus of the subfamily Lygosominae.
The South American foxes (Lycalopex), commonly called raposa in Portuguese, or zorro in Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, Lycalopex griseus, is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt.
A tuco-tuco is a neotropical rodent in the family Ctenomyidae. Tuco-tucos belong to the only living genus of the family Ctenomyidae, Ctenomys, but they include approximately 60 different species. The common name, "tuco-tuco" comes from the "tuc-tuc" sound they make while they dig their burrows.
The Satyrini is one of the tribes of the subfamily Satyrinae. It includes about 2200 species and is therefore the largest tribe in the subfamily which comprises 2500 species.
The Brazilian tuco-tuco is a tuco-tuco species from South America. It is found mainly in the state of Minas Gerais in southeastern Brazil, though Charles Darwin mentions it during his trip through present-day Uruguay.
Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America. This pinnately leaved, non-spiny genus includes both small palms lacking an aboveground stem and large trees. The genus has a complicated taxonomic history, and has often been split into four or five genera based on differences in the male flowers. Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus. This has been supported by recent molecular phylogenies.
The butterfly subtribe Euptychiina is a diverse group within the tribe Satyrini, occurring throughout Central and South America, in addition to a few species known from North America. Euptychiina is a predominantly lowland group, with the exception of one Asian taxon Palaeonympha opalinaButler, 1871 and the Andean genus ForsterinariaGray, 1973. The taxon was erected by Lee Denmar Miller.
Ithomiini is a butterfly tribe in the nymphalid subfamily Danainae. It is sometimes referred to as the tribe of clearwing butterflies or glasswing butterflies. Some authors consider the group to be a subfamily (Ithomiinae). These butterflies are exclusively Neotropical, found in humid forests from sea level to 3000 m, from Mexico to Argentina. There are around 370 species in some 40–45 genera.
Scapteromys is a genus of South American rodents in the tribe Akodontini of family Cricetidae. Three species are known, found in northern Argentina, southern Brazil, Paraguay and Uruguay. They are as follows:
Taygetis is a genus of satyrid butterflies found in the Neotropical realm.
Guaianaza is a monotypic butterfly genus of the subfamily Satyrinae in the family Nymphalidae. Guaianaza is considered a synonym of the genus Forsterinaria Gray, 1973. Its single species, Guaianaza pronophila, is found in the Neotropical realm.
Moneuptychia is a genus of satyrid butterflies found in the Neotropical realm.
Taydebis is a monotypic butterfly genus in the subfamily Satyrinae in the family Nymphalidae. The genus was established by André Victor Lucci Freitas in 2003. Its one species, Taydebis peculiaris, was found in Brazil and was described by Arthur Gardiner Butler in 1874.
Argyrophorus is a butterfly genus from the subfamily Satyrinae in the family Nymphalidae. It is distributed between Chile, Argentina and Perú. The systematic and circumscription of the genus is disputed.
Capillariidae is a family of parasitic nematodes. All its members are parasites in vertebrates when they are in their adult stage.
Hyantis is a monotypic nymphalid butterfly genus. Its sole species is Hyantis hodeva, which is found in New Guinea. It is uncertain which tribe this butterfly should be placed within.
Citrus leprosis(CL) is an economically important viral disease affecting citrus crops. This emerging disease is widely distributed in South and Central America, from Argentina to Mexico. The disease is associated with up to three different non-systemic viruses, which cause similar symptoms in the citrus hosts and are transmitted by the same vector, mites of the genus Brevipalpus; although they have vastly different genomes. Citrus leprosis virus nuclear type (CiLV-N) is found in the nuclei and cytoplasm of infected cells, while Citrus leprosis virus cytoplasmic type (CiLV-C) is found in the endoplasmic reticulum. In 2012, a new virus causing similar symptoms was found in Colombia and it was named Citrus leprosis virus cytoplasmic type 2 (CiLV-C2) due to its close similarity to CiLV-C. The cytoplasmic type viruses are the most prevalent and widely distributed of the three species.
Cratoavis is a genus of enantiornithines. The type and only currently described species is C. cearensis, from the Early Cretaceous of Araripe Basin, Ceará, Brazil. The fossil, an articulated skeleton with feathers attached to the wings and surrounding the body, extends considerably the temporal record of the group at South America.
Subdoluseps is a genus of skinks. They were all previously found in the genus Lygosoma.
Baruscapillaria is a genus of nematodes belonging to the family Capillariidae.
