Caribena  Caribena is a genus of spiders in the family Theraphosidae (tarantulas), found in the Antilles. The two species accepted were formerly placed in "Avicularia". Apart from a different distribution – "Avicularia" species are found in mainland South and Central America – "Caribena" is distinguished by having longer and thinner type II urticating hairs in a conspicuous patch on the upper surface of the abdomen. Males also have a differently shaped palpal bulb. The genus was erected in 2017 by Caroline Fukushima and Rogério Bertani for two species formerly placed in "Avicularia". The genus name is derived from the Spanish word "caribeña", meaning "from the Caribbean". Species of "Caribena" are distinguished from those of related genera by the possession of long (more than 1 mm) and very thin (less than 9 µm) type II urticating hairs carried on a conspicuous patch on the upper rear surface of the abdomen. Males have a pointed outgrowth (process) on the retrolateral lobe of the cymbium of the palpal bulb.  , the World Spider Catalog accepted the following species, both transferred from the genus "Avicularia":
