The Selenogyrinae are a subfamily of tarantulas found in Africa and Asia. [1]
The Selenogyrinae are characterized by a unique stridulating organ situated between the chelicerae, which consists of two very similar rows of hair. In Annandaliella , this is reduced. [2] Some species have labio sternal mounds and the clypeus is usually absent, or very narrow. [3]
The WSC currently accepts these genera: [1]
Selenogyrus and Euphrictus were the original genera in Hirst's 1908 Selenogyrinae. Annandaliella was added by Schmidt in 1993. [4]
Stridulation is the act of producing sound by rubbing together certain body parts. This behavior is mostly associated with insects, but other animals are known to do this as well, such as a number of species of fish, snakes and spiders. The mechanism is typically that of one structure with a well-defined lip, ridge, or nodules being moved across a finely-ridged surface or vice versa, and vibrating as it does so, like the dragging of a phonograph needle across a vinyl record. Sometimes it is the structure bearing the file which resonates to produce the sound, but in other cases it is the structure bearing the scraper, with both variants possible in related groups. Common onomatopoeic words for the sounds produced by stridulation include chirp and chirrup.
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas. Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living prey.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera. Most spiders in this family build trapdoor burrows. For example, the 20 millimetres (0.79 in) long Sipalolasma builds its burrow in rotted wood, with a hinged trapdoor at each end. The 10 millimetres (0.39 in) long Idioctis builds its burrow approximately 5 centimetres (2.0 in) deep, just below the high tide level, sealing the opening with a thin trapdoor.
The Harpactirinae are a subfamily of tarantulas which are native to the continent of Africa. Like many Old World tarantulas, they have a relatively strong venom, and can inflict a painful bite.
Annandaliella travancorica is a species of tarantula spider found in the Western Ghats of India. It was the first of three members of the genus Annandaliella to be described, therefore the type species.
Ceratogyrus is a genus of tarantulas found in southern Africa. They are commonly called horned baboons for the foveal horn found on the peltidium in some species. They are readily distinguished from other African theraphosid genera by the combined presence of a retrolateral cheliceral scopula, composed of plumose, stridulatory setae, and the strongly procurved fovea. The fovea is typically strongly procurved and in some species surrounds a distinct protuberance. this protuberance may take the form of a simple posterior extension of the caput, a low-set plug or a prominent, discrete conical projection. All Ceratogyrus species possess a pale yellow anteriorly placed, transverse, sub-abdominal band. This feature is not distinct in other Harpatirinae except Augacephalus junodi. The absence of dense, ventral femoral fringes on the palpi and legs I and II distinguish Ceratogyrus spp. from female A. junodi.
Annandaliella is a genus of tarantulas that was first described by A. S. Hirst in 1909. As of December 2019 it contains three species endemic to India: A. ernakulamensis, A. pectinifera, and A. travancorica. They are selenogyrid tarantulas, meaning they have a stridulating organ on the inner side of the chelicerae, consisting of an oblique row of five strong spines in front of several weak spines.
Pamphobeteus is a genus of tarantulas that was first described by Reginald Innes Pocock in 1901. It includes some of the largest spiders in the world.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. Currently, about 1,000 species have been identified. 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 urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
The Stromatopelminae are a subfamily of tarantulas native to West Africa and part of Central Africa. The subfamily was first proposed by Günter Schmidt in 1993.
Cyriopagopus is a genus of southeast Asian tarantulas found from Myanmar to the Philippines. As of March 2017, the genus includes species formerly placed in Haplopelma. It was first described by Eugène Louis Simon in 1887.
Euphrictus spinosus is a tarantula, subfamily Selenogyrinae, first described by A.S. Hirst in 1908. It is only known from the male, and from the Dja River, Cameroon.
Euphrictus is a genus of tarantula which is found in Africa. It is part of the subfamily Selenogyrinae.
Annandaliella ermakulamensis is a species of tarantula in the subfamily Selenogyrinae. It is one of three species in the genus Annandaliella and the first to be described in 73 years. It is native to Ermakulam, Kerala State, India.
The Eumenophorinae are a subfamily of tarantula spiders. They are known from genera distributed across Africa, southwestern countries in Saudi Arabia, and Madagascar and the associated islands.
Annandaliella pectinifera is a species of tarantula, a type of spider, in the subfamily Selenogyrinae. It is endemic to India.
Selenogyrus africanus is a species of tarantula, which is native to the Ivory Coast and is a member of the Selenogyrinae subfamily.
Selenogyrus caeruleus is a species of tarantula native to Sierra Leone.
Tliltocatl is a genus of spiders in the tarantula family Theraphosidae. It was split off from Brachypelma in 2020. Species in Tliltocatl are found predominantly in Mexico, with some species native to Central America. They are large burrowing tarantulas, without the striking red leg markings of Brachypelma species.
Grammostola alticeps is a New World spider in the tarantula family (Theraphosidae). It is endemic to Uruguay, Paraguay, and Brazil.
