Chilobrachys is a genus of Asian tarantulas that was first described by Ferdinand Anton Franz Karsch in 1892. [2] They are found in India, Myanmar, Malaysia, China, Vietnam, Thailand and Sri Lanka. They are usually medium or large-sized, and they can stridulate by using small spines present on the chelicerae. [3]

They have special stridulating organs in their chelicerae, which are made of short spines. Males have a palpal bulb which ends in a long and slender blade like spine, females have one pair of spermatheca. The anterior eyes form almost a straight line. Their legs have a narrower scapulae at the tip of the metatarsus. [3]

Deaths

No tarantula is considered deadly, but Chilobrachys have maybe the most potent venom, aside from Poecilotheria .[ citation needed ] Some cases have been reported where bites by Chilobrachys hardwickei resulted in gangrene and unconfirmed death. [4]

Species

As of July 2022 it contains thirty-one species, found in Asia: [1]

<i>Myrmarachne</i> Genus of spiders

Myrmarachne is a genus of ant-mimicking jumping spiders that was first described by W. S. MacLeay in 1839. They are commonly called ant-mimicking 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".

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.

<i>Cheiracanthium</i> Genus of spiders

Cheiracanthium, commonly called yellow sac spiders, is a genus of araneomorph spiders in the family Cheiracanthiidae, and was first described by Carl Ludwig Koch in 1839. They are usually pale in colour, and have an abdomen that can range from yellow to beige. Both sexes range in size from 5 to 10 millimetres. They are unique among common house spiders because their tarsi do not point either outward, like members of Tegenaria, or inward, like members of Araneus), making them easier to identify.

<i>Selenocosmia</i> Genus of spiders

Selenocosmia is a genus of tarantulas that was first described by Anton Ausserer in 1871. The genus is found in China, New Guinea, Australia, Indonesia, Myanmar, Malaysia, Laos, Vietnam, Philippines, India and Pakistan. They are commonly referred to as whistling or barking spiders, due to their ability to stridulate using lyra hairs.

<span class="mw-page-title-main">Tarantula</span> Family of spiders

Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 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.

<i>Olios</i> Genus of spiders

Olios is the largest genus of huntsman spiders, containing 166 species. They are found throughout the world, with most species occurring in hot countries. The genus was first described by Charles Athanase Walckenaer in 1837.

<i>Cyriopagopus</i> Genus of spiders

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.

<i>Cyrtarachne</i> Genus of spiders

Cyrtarachne is a genus of orb-weaver spiders first described by Tamerlan Thorell in 1868.

<i>Oxyopes</i> Genus of spiders

Oxyopes is a genus of lynx spiders found worldwide. It includes arounds 300 species and is classified under the lynx spider family Oxyopidae. Like other lynx spiders, they are easily recognizable by the six larger eyes arranged hexagonally on top of the head (prosoma), with the remaining smaller two eyes in front. They are also characterized by long spine-like bristles (setae) on their legs. They are ambush predators, actively hunting prey by sight. Though they produce and use silk, they do not build webs to capture prey.

<i>Phlogiellus</i> Genus of spiders

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.

<i>Poltys</i> (spider) Genus of spiders

Poltys is a genus of orb-weaver spiders first described by C. L. Koch in 1843. Many species are cryptic and are known to masquerade as leaves and twigs during the day, and build an orb web at night to capture prey. The shape of the abdomen which often gives the impression of a rough and broken branch can vary among individuals within a species. The web is eaten up before dawn and reconstructed after dusk.
