Dipluridae
The family Dipluridae, known as curtain-web spiders (or confusingly as funnel-web tarantulas, a name shared with other distantly related families) are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (''Atrax''), used to be classified in this family but have now been moved to Atracidae. Description Dipluridae lack rastella (stout conical spines on their chelicerae). Their carapace is characterized by the head region not being higher than the thoracic region. Their posterior median spinnerets (silk-extruding organs) are much shorter than their posterior lateral spinnerets, which have three segments, and are elongated (almost as long as their opisthosoma). Most of the species are medium to small-sized spiders; some may measure about 15 mm.Murphy & Murphy 2000 The cave species '' Masteria caeca'' is eyele ...

Masteria Caeca
''Masteria'' is a genus of Dipluridae, curtain web spiders that was first described by Ludwig Carl Christian Koch, L. Koch in 1873. They occur in the tropics of Central America, Central to South America, Asia and Micronesia, with one species found in Australia. ''M. petrunkevitchi'' males are long and females are long. ''M. lewisi'', ''M. barona'', and ''M. downeyi'' are slightly smaller and have only six eyes. Most species in the genus have six eyes, but two (''Masteria caecia'' and ''Masteria pecki'') have no eyes. Species it contains 42 species: *''Masteria aguaruna'' Passanha & Antônio Brescovit, Brescovit, 2018 – Peru *''Masteria aimeae'' (Alayón, 1995) – Cuba *''Masteria amarumayu'' Passanha & Brescovit, 2018 – Brazil *''Masteria angienae'' Víquez, 2020 — Costa Rica (Cocos Is.) *''Masteria barona'' (Arthur M.

Diplura (spider)
''Diplura'' is a genus of South American curtain web spiders that was first described by C. L. Koch in 1850. It is found in South America and Cuba belonging to the subfamily Diplurinae. Description Species of ''Diplura'' possess a lyra on their prolateral maxillae. ''Diplura'' species can be distinguished from '' Trechona'' sp. by the number of setae on this lyra. They differ from '' Harmonicon'' sp. by the leg formula (1423 in ''Harmonicon'', rather than 4123 in other genera of the subfamily) and the shape of the lyra bristles. Species it contains 17 species: *'' Diplura argentina'' (Canals, 1931) – Argentina *'' Diplura catharinensis'' ( Mello-Leitão, 1927) – Brazil *'' Diplura erlandi'' ( Tullgren, 1905) – Bolivia *'' Diplura garbei'' (Mello-Leitão, 1923) – Brazil *'' Diplura garleppi'' ( Simon, 1892) – Bolivia *'' Diplura lineata'' (Lucas, 1857) – Brazil *'' Diplura macrura'' (C.

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realised that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the ...

Linothele Fallax
''Linothele'' is a genus of curtain web spiders that was first described by Ferdinand Karsch in 1879. All but one of the described species are from South America (Bolivia, Brazil, Colombia, Ecuador, Peru and Venezuela) and adjacent Panama. The exception is ''L. septentrionalis'' from the far-away Bahamas, although it has certain features that suggest it may belong in another genus. ''Linothele'' females are stouter and tend to be more conspicuously colored than males. They make relatively complex webs that in most species are on or near the ground, mudbanks or rock walls (a few are arboreal), with females spending most of their life in a tunnel-like retreat. The male may wander and often inhabits a smaller web near a female's. The webs of ''Linothele'' species are commonly co-inhabited by tiny kleptoparasitic spiders of the genus ''Mysmenopsis''. Venom In humans, bites from ''Linothele'' typically cause mild pain and a numbness/tingling feeling that can last for a few days. The ...

Microstigmatidae
Microstigmatidae is a small family of spiders with about 38 described species in eleven genera. They are small ground-dwelling and free-living spiders that make little use of silk. The family was removed from the family Dipluridae in 1981. The subfamily Pseudonemesiinae from the family Ctenizidae was also transferred into the Microstigmatidae.

Nemesiidae
Nemesiidae is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae". The family is sometimes referred to as wishbone spiders due to the shape of their burrows. Description Nemesiidae are relatively large spiders with robust legs and a body that is nearly three times as long as it is wide. They are darkly colored, brown to black, though some have silvery hairs on their carapace. '' Atmetochilus'' females can grow over long. They live in burrows, often with a hinged trapdoor. This door is pushed up while the spider waits for passing prey. They rarely leave their burrows, catching prey and withdrawing as quickly as possible. Some of these burrows have side tubes. For the east-Asian genus '' Sinopesa'' it is uncertain whether it builds burrows at all. Genera , the World Spider Catalog accepts the following genera: *'' Amblyocarenum'' Simon, 1892 *'' Br ...

Anamidae
Anamidae is a family of Australian mygalomorph spiders. It was first described as a tribe by Simon in 1889, then raised to the subfamily Anaminae of the family Nemesiidae, before being raised to a family level by Opatova et al. in 2020. Taxonomy The tribe Anamini was first described by Eugène Simon in 1899. In 1982, Barbara York Main distinguished the tribe Teylini from the tribe Anamini by technical differences, including a narrow band of cuspules on the maxillae and the absence of a spine-bearing spur on the first tibia of males (except in ''Teyloides''). A molecular phylogenetic study in 2018 found that Anamini excluding Teylini was not monophyletic, and so merged the former Teylini into Anamini, placing the tribe in the subfamily Anaminae of the family Nemesiidae. In 2020, Opatova et al. raised the group to the rank of family, including all nine genera previously placed in the Anamini.
