In taxonomy, binomial nomenclature, also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name, or a scientific name; more informally it is also historically called a Latin name. In the ICZN, the system is also called binominal nomenclature, "binomi'N'al" with an "N" before the "al", which is not a typographic error, meaning "two-name naming system".
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature. The rules principally regulate:
The Pitheciidae are one of the five families of New World monkeys now recognised. Formerly, they were included in the family Atelidae. The family includes the titis, saki monkeys and uakaris. Most species are native to the Amazon region of Brazil, with some being found from Colombia in the north to Bolivia in the south.
The bearded sakis, or cuxiús, are five or six species of New World monkeys, classified in the genus Chiropotes. They live in the eastern and central Amazon in South America, ranging through southern Venezuela, Guyana, Suriname, French Guiana and northern and central Brazil. The species are entirely allopatric, their distributions being separated by major rivers.
Pitheciinae is a subfamily of the New World monkey family Pitheciidae. It contains three genera and 14 species. Pitheciines are forest dwellers from northern and central South America, east of the Andes.
The white-eared titi monkey also known as the Bolivian titi or Bolivian gray titi, is a species of titi monkey, a type of New World monkey, from eastern Bolivia and an area of western Brazil. The species has a range that extends east from the Manique River in Beni Department, Bolivia to southern Rondônia in Brazil. The southern end of its range includes forests around the city of Santa Cruz de la Sierra.
The white-nosed saki is a species of bearded saki, a type of New World monkey, endemic to the south-central Amazon rainforest in Brazil. Both its scientific and common name were caused by the authors working from dead specimens, where the skin on and around the nose fades to a whitish color. In living individuals, the nose is actually bright pink. Pelage on the body tends to be black in males and brown to brownish-grey in females. No other species of the genus Chiropotes have a brightly coloured nose.
The black bearded saki is a species of New World monkey, native to the Amazon rainforest of South America, specifically to an area of north-eastern Brazil. It is one of five species of bearded saki. Bearded sakis are medium-sized (50 cm), mostly frugivorous primates, specialised in seed predation. The genus name Chiropotes means "hand-drinker" as they have been observed using their hands as ladles for scooping water into their mouths. This behavior is thought to be a way of maintaining and protecting their characteristic beards. The black bearded saki's habitat has undergone heavy habitat fragmentation, making the future conservation status of the species uncertain.
The red-backed bearded saki is a New-World monkey, from South America. It is a species of bearded saki.
The brown-backed bearded saki is one of five species of bearded saki, a type of New World monkey. It is endemic to the Amazon in north-western Brazil and southern Venezuela. It is possible the correct scientific name for this species is C. chiropotes, in which case the more easterly red-backed bearded saki would be named C. sagulatus. The IUCN lists the reddish-brown bearded saki as a valid species, with C. israelita as a synonym, but also notes they might both be valid.
Tapirapé Biological Reserve is a biological reserve in the state of Pará, Brazil.
Igarapé Gelado Environmental Protection Area is a protected area in the state of Pará, Brazil. It contains cultivated land and Amazon biome.
In zoological nomenclature, emendations are intentional alterations made to the spelling of taxon names. In bacteriological nomenclature, emendations are made to the circumscription of a taxon.
Palmadusta humphreyii, common name : Humphrey's cowrie, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.
The Carajás National Forest is a national forest in the state of Pará, Brazil. It covers the Serra dos Carajás, an area with large deposits of iron ore, and attempts to combine the roles of supporting mineral extraction with preserving the environment and maintaining biodiversity.
Tapirapé-Aquiri National Forest is a national forest in the state of Pará, Brazil. It is surrounded by other protected areas, so has suffered relatively little from deforestation.
Spintharus rallorum is a species of comb-footed spider in the family Theridiidae. It is found in Puerto Rico and Saint Kitts and Nevis. It is one of 15 new species described in 2018. The authors spelt the name as Spintharus ralli, but noted that it honoured the "grandparents of the first author of the species." As the name refers to more than one person, the World Spider Catalog changed it from the Latin genitive singular to the genitive plural.
