Aviculariinae
The Aviculariinae are a subfamily of spiders in the family Theraphosidae (tarantulas). They can be distinguished from other theraphosids by a number of characters. Their legs have no or few spines on the underside (ventral surface) of the tibial and metatarsal joints of the legs. The last two leg joints (the metatarsi and tarsi) have brushes of hairs (scopulae) that extend sideways, particularly on the front legs, giving them a spoon-like (spatulate) appearance. Females have two completely separated spermathecae. Taxonomy The earliest classification of the mygalomorph spiders to include sufficient genera to be reasonably comprehensive was that of Eugène Simon in 1892. He recognized only two mygalomorph families; his Avicularidae taxon includes at least 12 modern families. The earliest equivalent to the modern subfamily Aviculariinae is considered to be Simon's 1889 tribe Aviculariae, which included three genera: ''Avicularia'', '' Tapinauchenius'' and ''Scodra'' (now '' Stromato ...

Theraphosidae
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Ybyrapora
''Ybyrapora'' is a genus of spiders in the family Theraphosidae (tarantulas), found in Brazil. Its species were formerly placed in the genus '' Avicularia''. Description ''Ybrapora'' consists of species that are smaller than most aviculariines. Females have strongly curved, almost non-sclerotized (i.e. non-hardened) spermathecae. The tibial apophysis (outgrowth) on the first leg is absent or small. Individuals show major colour changes as they mature. Immature spiders have a central reddish mark with jagged edges running along the centre of the abdomen, surrounded by a dark area connected to similarly dark coloured stripes running across the abdomen. These patterns become duller or disappear in adults, particularly females.

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. Diagnostic They own type 2 urticating hairs, which are very slender, on a clearly visible area of the opisthosoma. These hairs being longer than 1mm. And males can also be distinguished by the sharp spine like "process" in the retrolateral face of the cymbium. Taxonomy 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' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antillena
''Antillena'' is a genus of spiders in the family Theraphosidae (tarantulas). , the genus contained a single species, ''Antillena rickwesti'', found in the Dominican Republic. Taxonomy The species was first described in 2013 by Rogério Bertani and Jeremy Huff, as ''Avicularia rickwesti''. Only the female was known. The specific name recognizes the contributions to the study of the family Theraphosidae by Rick C. West. At the time of description, it was noted that the species was "very distinct" from others in the genus '' Avicularia'', but no alternative generic placement seemed better. A phylogenetic study published in 2017 suggested that the species was sufficiently distinct from ''Avicularia'' to be placed in a separate new genus, ''Antillena''. The generic name refers to the Antilles The Antilles (; gcf, label=Antillean Creole, Antiy; es, Antillas; french: Antilles; nl, Antillen; ht, Antiy; pap, Antias; Jamaican Patois: ''Antiliiz'') is an archipelago bordered ...

Typhochlaena
''Typhochlaena'' is a genus of small-bodied tarantulas with an arboreal trapdoor lifestyle. All the species except for ''T. seladonia'' were first described by Rogério Bertani in 2012. Characteristics ''Typhochlaena'' differs from all other aviculariine species by having a domed, short distal segment on the posterior lateral spinneret; the sternum is as long as wide, truncated behind; they are also quite small, with type II urticating hairs.Bertani, R.

Iridopelma
''Iridopelma'' is a genus of Brazilian tarantulas that was first described by Reginald Innes Pocock in 1901. Diagnosis Males of this genus can be distinguished by the tibial spurs on leg 1 and 2, while females differ from most other genera by the anterior eye row, which is strongly curved forward. ''Avicularia'' and ''Typhochlaena'' both own the latter characteristics; however, ''Iridopelma'' can be distinguished from ''Avicularia'' by the spermatheca, which lacks a curvature, and from ''Typhochlaena'' by the spinnerets, which are finger-shaped.

Ephebopus
''Ephebopus'' is a genus of northeastern South American tarantulas that was first described by Eugène Louis Simon in 1892. Its relation to other tarantulas is one of the most uncertain in the family, and it has been frequently moved around and has been placed in each of the eight subfamilies at least once. Description They normally grows to a legspan of . Most live in burrows, though ''E. murinus'' spends an adolescent stage living in trees. Like many other New World tarantulas, these spiders will brush urticating hairs from their bodies as a defense against potential predation. However, these spiders are unique because instead of the abdomen, these hairs are located on the pedipalps, and are removed by rubbing the palps against the chelicerae. Diagnosis They can be differentiated from all other tarantulas by the urticating patch of type 5 urticating hairs, on the pedipalp femora. Species it contains five species, found in Brazil, Suriname, Guyana, and French Guiana: *'' Eph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

They have a straight front eye row and males have a spinose spur on the first tibia. Females have two spermathecae lacking lobes or constrictions that have a slight curvature in the middle.

Avicularia
''Avicularia'' is a genus of the family Theraphosidae containing various species of arboreal tarantulas. The genus is native to Panama, the Caribbean and tropical South America. Each species in the genus has very distinguishable pink foot pads. Species belonging to this genus are amongst the relatively small exception of tarantulas that can jump moderate distances as juveniles, with most tarantulas being limited to lunges of 3-4 centimeters. Urticating hairs are distinct to new world tarantulas including the Avicularia that are attached to the spider's cuticle ''via'' a stalk. These spiny, barbed hairs are used as a defense against potential intruders as well as embedded into silk to protect the egg sac. In active defense, the hairs are released by contact with the stimulus and rubbed in. At least three species of Avicularia are threatened by habitat loss and illegal trafficking, due to their popularity as exotic pets. '' Avicularia avicularia'' are among the tarantulas most ...
