Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks.
Wasaka is a genus of African corinnid sac spiders first described by C. R. Haddad in 2013.
Penestomus is a genus of African araneomorph spiders in the family Penestomidae, and was first described by Eugène Louis Simon in 1902. The genus was formerly included in the family Eresidae, but was elevated to its own family in 2010. It is now considered closer to Zodariidae.
Trachelidae is a family of araneomorph spiders first described by Eugène Simon in 1897 as a subfamily called "Tracheleae". The Trachelidae family, also known as "ground sac spiders", is within the group of spiders known as the RTA clade, which includes mostly wandering spiders that do not use webs. Spiders in the Trachelidae family are characterized as being 3-10mm long and having a red cephalothorax and a yellow/tan abdomen. They are commonly found indoors. It was placed in the family Clubionidae, then later in Corinnidae when the Clubionidae were split up. The first study that suggested Trachelidae should be considered its own family was done by Deeleman-reinhold in 2001 as part of an analysis of RTA Clade spiders. An analysis by Martín J. Ramírez in 2014 suggested that it was not closely related to other members of the Corinnidae, and was better treated as a separate family. It was then placed in the CTC clade of spiders, or the Claw Tuft Clasper clade, which is a group of spiders that have two tarsal claws with tufts of hair.
Austrophaea is a monotypic genus of African corinnid sac spiders containing the single species, Austrophaea zebra. It was first described by R. F. Lawrence in 1952, and has only been found in South Africa.
Copuetta is a genus of African corinnid sac spiders first described by C. R. Haddad in 2013.
Echinax is a genus of Asian and African corinnid sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Austrachelas is a genus of African long-jawed ground spiders in the family Gallieniellidae, and was first described by R. F. Lawrence in 1938. Originally placed with the corinnid sac spiders, it was moved to the Gallieniellidae in 2009.
Wanda Wesołowska is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s.
Afraflacilla venustula is a species of jumping spider in the genus Afraflacilla that lives in South Africa. The spider was first described in 2009 by Wanda Wesołowska and Charles Haddad. Originally allocated to the genus Pseudicius, it was moved to its current name by Jerzy Prószyński in 2016. The spider is small, with a carapace that is between 1.7 and 2.0 mm long and an abdomen between 1.8 and 2.5 mm long. The male is larger than the female. The carapace is light brown, although some males are darker, with a black eye field. The male abdomen is black with a pattern of four pairs of white spots, like Pseudicius sengwaensis. The female abdomen is yellowish with four brown spots. The legs are generally yellow, apart from the front pair on the male, which are brown, longer and stouter. The male also has a distinctive bulbous shape to its palpal bulb and a longer embolus than related species.
Afroceto is a genus of African araneomorph spiders in the family Trachelidae, first described by R. Lyle & C. R. Haddad in 2010.
Fuchiba is a genus of African araneomorph spiders in the family Trachelidae, first described by C. R. Haddad & R. Lyle in 2008.
Fuchibotulus is a genus of South African and Mozambican araneomorph spiders in the family Trachelidae, first described by C. R. Haddad & R. Lyle in 2008. As of April 2019 it contains only three species.
Jocquestus is a genus of African araneomorph spiders in the family Trachelidae, first described by R. Lyle & C. R. Haddad in 2018.
Patelloceto is a genus of African araneomorph spiders in the family Trachelidae, first described by R. Lyle & C. R. Haddad in 2010. As of April 2019 it contains only three species.
Planochelas is a genus of African araneomorph spiders in the family Trachelidae, first described by R. Lyle & C. R. Haddad in 2009. As of April 2019 it contains only three species from Ghana, Uganda, and Ivory Coast.
Poachelas is a genus of African araneomorph spiders in the family Trachelidae, first described by C. R. Haddad & R. Lyle in 2008.
Spinotrachelas is a genus of South African araneomorph spiders in the family Trachelidae, first described by C. R. Haddad in 2006.
Griswoldella is a monotypic genus of east African corinnid sac spiders containing the single species, Griswoldella aculifera. It was first described by C. R. Haddad in 2021, and it has only been found in Madagascar.
Capobula is a genus of southern African spiders in the family Trachelidae. The type species was first described by Eugène Simon from a juvenile found in South Africa. It was placed with Orthobula for several morphological similarities, including a large sclerite beneath the abdomen and spines behind several of the legs. After a more thorough examination in 2021, including both male and female adults, enough distinctive features were found in the holotype and several other newly discovered species to warrant a new genus.
