The True Red Tailed Boas evolved east of the Andes mountains so Common Boas and True Red Tailed Boas are separated by the Andes mountains allowing them to evolve into two different species. The new scientific name for the Common Boa is Boa imperator reflecting that it is a separate species notice that the subspecies name ” constrictor ” is now missing from the name. Due to new genetic evidence the Common Boa has found to be a completley different species from the Red Tailed Boa and are no longer considered a subspecies. The first successful breeding in South Africa of Guyana Red Tailed Boas happened a few weeks ago so they are not commonly bred in South Africa at all. In fact Common Boas can be found as far north as the Sonoran desert in Mexico, whilst Red Tailed Boas are found further south in countries such as Guyana and Surinam where most captive lines of true Red Tailed Boas come from.True Red Tailed Boas have bright red tails whilst Common Boas tend to have brownish or orange tail markings. Only the so called True Red Tailed Boa ( Boa constrictor constrictor) can be called Red Tailed Boas, which live in the Amazon basin and grow much larger than the Common Boas ( Boa constrictor imperator) which are a central American species. There are 8 subspecies of Boa Constrictor with the most commonly available subspecies in the pet trade being Boa Constrictor Imperator. PMID 24315866.It may come to you as a shock but the Red Tailed Boa you have as a pet, see in a pet store, reptile expo or on an online ad is not actually a Red Tailed Boa to explain this we must look into the taxonomy of Boa Constrictor subspecies. "Toward a Tree-of-Life for the boas and pythons: Multilocus species-level phylogeny with unprecedented taxon sampling". "Phylogeny of South American and Malagasy boine snakes: Molecular evidence for the validity of Sanzinia and Acrantophis and biogeographic implications".

To add further to the naming confusion, many species of snake in the family Boidae are known colloquially as "boas".
These snakes are therefore correctly represented in their own genera: Sanzinia and Acrantophis. However, it has since been shown that the Malagasy boids and Boa constrictor do not form a monophyletic group, and the lumping of Sanzinia, Acrantophis and Boa was, therefore, an error. Kluge (1991) moved the genera Sanzinia and Acrantophis into Boa, based on a phylogeny derived from morphological characters. Lucia), on San Andrés, Providencia and many other islands along the Caribbean coasts of Mexico and Central and South America. One species is present in the Lesser Antilles ( Dominica and St. ) Not including the nominate subspecies.īoa species are found in northern Mexico through Central America ( Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama) to South America north of 35°S ( Colombia, Ecuador, Peru, Venezuela, Guyana, Suriname, French Guiana, Brazil, Bolivia, Uruguay and Argentina).Mexico, Central America and South America
The Online Etymology Dictionary says that the word comes from the "late 14c., "large snake," from Latin boa, type of large serpent mentioned in Pliny's "Natural History " origin unknown (in medieval folk etymology the name was associated with Greek bous "ox")." Species Image Five extant species, and one extinct, are currently recognized.
Boa is a genus of boas found in Mexico, the Caribbean, and Central and South America.
