Anacondas or water boas are a group of large snakes of the genus Eunectes. They are found in tropical South America. Four species are currently recognized.
Phoneutria is a genus of spiders in the family Ctenidae of potential medical significance to humans. They are mainly found in northern South America, with one species in Central America. Members of the genus are commonly referred to as Brazilian wandering spiders. Other English names include armed spiders and banana spiders.
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. They belong to the Orthopteran subfamily Ensifera, having long, whip-like antennae and has been reduced in terms of the older literature, with taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Walker.
Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the northern Andes, the Caribbean, and the Atlantic Forest of eastern Brazil. Other centers of diversity include New Caledonia and Madagascar. Many of the species that occur in the Old World have received a new classification into the genus Syzygium.
Gondwanatitan was a titanosaurian sauropod dinosaur. Gondwanatitan was found in Brazil, at the time part of the southern supercontinent Gondwana, in the late Cretaceous Period. Like some other sauropods, Gondwanatitan was tall and ate tough shoots and leaves off of the tops of trees. G. faustoi's closest relative was Aeolosaurus.
Maxakalisaurus is a genus of titanosaur dinosaur, found in the Adamantina Formation of Brazil, in the state of Minas Gerais in 1998. The genus name is derived from the tribe of the Maxakali; Topa is one of their divinities.
Desmoncus is a genus of mostly climbing, spiny palms native to the Neotropics. The genus extends from Mexico in the north to Brazil and Bolivia in the south, with two species present in the southeastern Caribbean.
Oenocarpus is a genus of pinnate-leaved palms (Arecaceae) native to Trinidad, southern Central and tropical South America. With nine species and one natural hybrid, the genus is distributed from Costa Rica and Trinidad in the north to Brazil and Bolivia in the south.
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.
Acanthochelys is a genus of turtles, the spiny swamp turtles, in the family Chelidae, subfamily Chelinae, found in South America. Until recently, the species of this genus were considered to be members of the genus Platemys, but were moved to the resurrected genus originally described by Gray (1873) based on the type species by monotypy Acanthochelys spixii.
Roupala is a Neotropical genus of woody shrubs and trees in the plant family Proteaceae. Its 34 species are generally found in forests from sea level to 4000 m altitude from Mexico to Argentina.
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. As of April 2018, Index Fungorum accepts 645 species in the family.
Caririemys is an extinct genus of side-necked turtles, belonging to the Pelomedusoides of the family Euraxemydidae. The type species is C. violetae. A single fossil of an individual was found in the Santana Formation in Brazil, an 80-million-year-old Late Cretaceous deposit that has so far preserved other fossil reptiles such as dinosaurs and crocodilians.
Senoculus is a genus of araneomorph spiders in the family Senoculidae, and was first described by Władysław Taczanowski in 1872. It is the only genus in the family Senoculidae.
Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways. They differ from other spiders in lacking book lungs and having the posterior median spinnerets anteriorly displaced to form a transverse row with the anterior lateral spinnerets. Most species have only two eyes, which is also unusual among spiders. A few species of Caponiidae variously have four, six or eight eyes. In some species the number of eyes will increase when the spiderling changes its skin as it grows towards adulthood.
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.
The Jurasaidae are a family of Coleoptera known from 5 rare species in the Brazilian Atlantic rainforest; all known species have neotenic females and normal males.
Itapecuruemys is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Itapecuru Formation of Brazil. It is a monotypic genus, with only type species Itapecuruemys amazoniensis known.
Inaechelys is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Maria Farinha Formation of Brazil. The genus consists solely of type species I. pernambucensis.
Arrudatitan is an extinct genus of titanosaur sauropod dinosaur known from the Late Cretaceous (Campanian-Maastrichtian)-aged Adamantina Formation of Brazil. The type species, A. maximus, was named and described in 2011 as a species of Aeolosaurus, but was separated into its own genus in 2021. It was relatively gracile for a titanosaur.
