The family Cyrtaucheniidae, known as wafer-lid trapdoor spiders, are a widespread family of Mygalomorphae 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".
Thiania is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846.
Idiopidae, also known as armored trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889. They have a large body similar to tarantulas.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera.
Ferdinand Anton Franz Karsch or Karsch-Haack was a German arachnologist, entomologist and anthropologist.
Idiops is a genus of armored trapdoor spiders that was first described by Josef Anton Maximilian Perty in 1833. It is the type genus of the spurred trapdoor spiders, Idiopidae. Idiops is also the most species-rich genus of the family, and is found at widely separated locations in the Neotropics, Afrotropics, Indomalaya and the Middle East. Females live in tubular burrows lined with a thick layer of white silk. These typically have a D-shaped lid that fits into the entrance like a cork, and some burrows have two entrances. The lid may consist of mud, moss or lichen, which is bound below by a thick layer of silk. As in all genera of this family, the anterior lateral eyes (ALE) are situated near the clypeal margin, far in front of the remaining six eyes, which are arranged in a tight group. The males which are smaller in size, wander about or occasionally live in burrows. Like other mygalomorphs, they are relatively large and long-lived. Forest clearance and agricultural practices that loosen the soil and enhance erosion, besides soil removal for brick making have been pointed out as serious threats to some Indian species. Species ranges are poorly known – in India for instance, most species are known only from their type localities.
Heligmomerus is a genus of armored trapdoor spiders that was first described by Eugène Louis Simon in 1892.
Campostichomma is a genus of spiders in the family Udubidae native to Sri Lanka. Many of its species were moved to either Griswoldia or Devendra. This genus was originally placed in the family Agelenidae. It was moved to Miturgidae in 1967, to Zoropsidae in 1999, then to Udubidae in 2015.
The Eumenophorinae are a subfamily of tarantula spiders. They are known from genera distributed across Sub-Saharan Africa, the south of the Arabian peninsula, Madagascar and its associated islands, and parts of India.
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. They are usually medium or large-sized, and they can stridulate by using small spines present on the chelicerae.
Gasteracantha remifera is a species of spiny orb-weaver spider in the genus Gasteracantha. It is found in Sri Lanka and India, and it has a pair of long, club-shaped spines on its abdomen.
Plagiobothrus is a monotypic genus of Asian brushed trapdoor spiders containing the single species, Plagiobothrus semilunaris. It was first described by Ferdinand Karsch in 1892, and has only been found in Sri Lanka, documented from the regions of Peradeniya and Kandy. It is about 24 millimetres (0.94 in) long and has a deep brown carapace and limbs. Its abdomen is black above and brown beneath.
Scalidognathus oreophilus, is a species of spider of the genus Scalidognathus. It is endemic to Sri Lanka.
Scalidognathus radialis, is a species of spider of the genus Scalidognathus. It is endemic to Sri Lanka.
Stasina is a genus of huntsman spiders that was first described by Eugène Louis Simon in 1877. Many former species have been transferred to Thelcticopis and Neostasina.
Tigidia is a genus of brushed trapdoor spiders first described by Eugène Simon in 1892.
Haploclastus is a genus of Indian tarantulas that was first described by Eugène Louis Simon in 1892. It is considered a senior synonym of Phlogiodes.
Buthoscorpio is a genus of scorpions in the family Buthidae.
