Ornithoctoninae is a subfamily of tarantulas found in Southeast Asia. It was first erected in 1895 by Reginald Innes Pocock based on the type specimen Ornithoctonus andersoni.
The Ornithoctoninae comprise a theraphosid subfamily, which is widely distributed in Asia from Myanmar to South China in the north and as far as to Halmahera in the Indonesian archipelago in the south, and in all the ranges in between. Most species in the subfamily live fossorially in burrows, though several species live arboreally. They are known as defensive spiders; when disturbed, they quickly retreat into their burrows or dig themselves into the soil. When neither is a possibility, they assume a defensive posture. When provoked, they strike the aggressor repeatedly with the anterior legs; if the aggressor does not retreat, these spiders have been known to bite. Though not deadly, the effects of the venom can be very unpleasant, including pain, swelling, and arthritis-like stiffness in the joints of the extremity affected.
The theraphosid subfamily Ornithoctoninae is defined by a combination of characteristics: Presence of retrolateral scopula of filiform setae on the cheliceral base, a small row of larger filiform paddle setae retrolaterally ventrobasally in connection to the retrolateral cheliceral scopula, and arrangement of stridulatory spines prolaterally on maxilla. The characteristic of retrolateral scopula of filiform setae on the cheliceral base is shared by the African subfamily Harpactirinae, but the Ornithoctoninae can be distinguished from the Harpactirinae by the geographic distribution range and the presence of the other characteristics mentioned, which are lacking in the Harpactirinae.
Specimens from the genera Haplopelma , Cyriopagopus , and Ornithoctonus are frequently kept as pets. The most commonly kept species are: H. albostriatum, H. hainanum, H. lividum, H. longipes, H. minax, H. schmidti, O. aureotibialis, and C. schioedtei. More species are kept and new species enter the hobby every now and then, but most of this material needs to be properly identified or described.

Myrmarachne is a genus of ant-mimicking jumping spiders that was first described by W. S. MacLeay in 1839. They are commonly called antmimicking spiders, but they are not the only spiders that have this attribute. The name is a combination of Ancient Greek μύρμηξ, meaning "ant", and ἀράχνη, meaning "spider".
Cyriopagopus hainanus is a species of spider in the family Theraphosidae (tarantulas), found in China. It is one of a number of species from China and Vietnam known as "Chinese bird spider". It produces a venom containing numerous compounds capable of blocking neurotransmitters, including neurotoxic peptides called hainantoxins.
Cyriopagopus schmidti is a species of spider in the family Theraphosidae (tarantulas), found in China and Vietnam. It is one of a number of species known as "Chinese bird spider" and "Chinese earth tiger". Haplopelma huwenum was synonymized with this species in 2008. Spiders under this name and its synonyms have been shown to produce toxins called huwentoxins.
Selenocosmia is a genus of tarantulas that was first described by Anton Ausserer in 1871. The genus is found in China, New Guinea, Indonesia, Australia, Indonesia, Myanmar, Malaysia, Laos, Vietnam, Phillippines and Pakistan. They are commonly referred to as whistling or barking spiders, due to their ability to stridulate using lyra hairs.
Heteropoda is a genus of spiders in the family Sparassidae, the huntsman spiders. They are mainly distributed in tropical Asia and Australia, while at least one species, H. venatoria, has a cosmopolitan distribution, and H. variegata occurs in the Mediterranean.
Ornithoctonus is a genus of Southeast Asian tarantulas that was first described by Reginald Innes Pocock in 1892. As of May 2020 it contains three species, found in Thailand and Myanmar: O. andersoni, O. aureotibialis, and O. costalis.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. Currently, 1039 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.
The Malaysian earthtiger tarantula, scientific name Omothymus schioedtei, is a species of spider in the family Theraphosidae (tarantulas), found in Peninsular Malaysia. It is also known by the synonym Cyriopagopus schioedtei.
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.
The Ischnocolinae are a problematic subfamily of tarantulas. In 1892, Eugène Simon based the group, which he noted was only weakly homogeneous, on the presence of divided tarsal scopulae. This feature was later considered to be plesiomorphic, and both morphological and molecular phylogenetic studies have shown that, as traditionally circumscribed, the subfamily is not monophyletic. A much more narrowly defined Ischnocolinae sensu stricto was proposed in 2014. One of the authors of that proposal subsequently said that no further taxonomic changes should be considered until there had been a more comprehensive sampling of the subfamily. As of January 2021, the status of the Ischnocolinae remains unresolved.
Chilobrachys is a genus of Asian tarantulas that was first described by Ferdinand Anton Franz Karsch in 1892. They are found in India, Myanmar, Malaysia, China, Vietnam, Thailand and Sri Lanka. There size are usually medium or large, and they can stridulate by using small spines on the chelicerae.
Phlogiellus is a genus of tarantulas that was first described by Reginald Innes Pocock in 1897. They are found throughout Asia and Papua New Guinea, including Indonesia, the Philippines, Papua New Guinea, China, Myanmar, Malaysia, Borneo, Thailand, the Solomon Islands and Taiwan. Phlogiellus is part Latin and part Greek, the first part being "φλóξ φλoγóϛ", meaning flame, the second part being "ellus" which is a latin diminutive suffix.
Augacephalus is a genus of harpacterine theraphosid spiders. It has three species, all of which are found in Africa.
Lampropelma is a genus of Indonesian tarantulas that was first described by Eugène Louis Simon in 1892. As of March 2020 it contains two species, found in Indonesia.
Phormingochilus is a genus of Indonesian tarantulas that was first described by Reginald Innes Pocock in 1895. They are occasionally kept as exotic pets, and are known for moving in bursts of speed and being defensive when cornered.
Günter E. W. Schmidt was a German arachnologist and author of a standard German work on tarantulas, Die Vogelspinnen. He has been described as one of the fathers of German arachnology.
The Selenocosmiinae are a subfamily of tarantulas found throughout South-East Asia and Australia. This subfamily is defined by the presence of a lyra on the maxillae and strikers on the chelicerae, allowing these spiders to stridulate and produce a "hissing" sound. However some species within Phlogiellus may have secondary lost their lyra but retain their strikers. The monophyly of the subfamily has been only tested using genetic data with a handful of genera or species in a few studies. However, these studies found genera that had been previously placed in this subfamily were actual their own separate subfamily (Poecilotheria) and that Selenocosmiinae is most closely related to the Indian Thrigmopoeinae. As of 2021, Selenocosmiinae contains 11 genera.
μ-THTX-Cl6a, also known as Cl6a, is a 33-residue peptide toxin extracted from the venom of the spider Cyriopagopus longipes. The toxin acts as an inhibitor of the tetrodotoxin-sensitive (TTX-S) voltage-gated sodium channel (NaV1.7), thereby causing sustained reduction of NaV1.7 currents.
Ornithoctonus aureotibialis is a tarantula species in the Ornithoctonus genus, it was first described by Volker von Wirth and Boris F. Striffler in 2005. It is named for the Latin, aureus being "golden" and tibia. Because of the gold or orange coloured line of hair in the tibiae of the legs in subadult and adult females and subadult males. It's common name is Thailand Golden Fringe, as the name may suggest it is found in Thailand, Myanmar and Malaysia. It is sometimes kept as a pet, and are captive breed.
