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.
Fluctus is a small genus of east Asian corinnid sac spiders. It was first described by C. Jin and F. Zhang in 2020, and it has only been found in China. As of November 2021 it contains only two species: F. bannaensis and F. tengchongensis.
Wasaka is a genus of African corinnid sac spiders first described by C. R. Haddad in 2013.
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.
Orthobula is a genus of araneomorph spiders first described by Eugène Simon in 1897 as a member of Liocranidae. It was transferred to Corinnidae in 2002, to Phrurolithidae in 2014, and to Trachelidae in 2017.
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.
Mandaneta is a monotypic genus of African corinnid sac spiders containing the single species, Mandaneta sudana. It was first described by Embrik Strand in 1932, and has only been found in Central Africa.
Vendaphaea is a monotypic genus of African corinnid sac spiders containing the single species, Vendaphaea lajuma. It was first described by C. R. Haddad in 2009, and has only been found in South Africa.
Entypesa is a genus of African mygalomorph spiders in the family Entypesidae. It was first described by Eugène Louis Simon in 1902. Originally placed with the curtain-web spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Entypesidae in 2020. It is a senior synonym of Pseudohermacha.
