Melanesotypus is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2017 [update] , it contains only one species, Melanesotypus guadal, from the Solomon Islands. [1]
The sac spiders of the family Clubionidae have a very confusing taxonomic history. Once, this family was a large catch-all taxon for a disparate collection of spiders, similar only in that they had eight eyes arranged in two rows and conical anterior spinnerets that touched, and were wandering predators that built silken retreats, or sacs, usually on plant terminals, between leaves, under bark, or under rocks. These are now recognized to include several families, some of which are more closely related to the three-clawed spiders, like lynx and wolf spiders, than to Clubionidae and related families.
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.
The Dionycha are a clade of spiders (Araneomorphae:Entelegynae), characterized by the possession of two tarsal claws with tufts of hairs (setae) beside them, which produce strong adhesion, enabling some species to climb glass. The circumscription of the group has varied widely; a 2021 analysis resulted in about 20 families, including Salticidae, Gnaphosidae, and Clubionidae.
The Entelegynae or entelegynes are a subgroup of araneomorph spiders, the largest of the two main groups into which the araneomorphs were traditionally divided. Females have a genital plate (epigynum) and a "flow through" fertilization system; males have complex palpal bulbs. Molecular phylogenetic studies have supported the monophyly of Entelegynae.
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.
Nyssus coloripes, known commonly in Australia as the orange-legged swift spider, but also as the spotted ground swift spider, the fleet footed spider and the painted swift spider, is a spider belonging to the family Corinnidae. It is found commonly in Australia and New Zealand.
Phrurolithidae is a family of araneomorph spiders, known as guardstone spiders. The family was first described by Nathan Banks in 1892. First included in the Corinnidae as the subfamily Phrurolithinae, later phylogenetic studies justified a separate family.
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.
Pristidia is a genus of Asian sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Olbus is a genus of South American corinnid sac spiders first described by Eugène Simon in 1880 as a huntsman spider. It was moved to the sac spider family in 1988, then to the Corinnidae in 2001.
Parachemmis is a genus of corinnid sac spiders first described by Arthur M. Chickering in 1937 as a genus of ground spiders. It was transferred to Liocranidae in 1969, and to Corinnidae in 1994.
Allomedmassa is a genus of spiders in the family Corinnidae. It was first described in 2014 by Dankittipakul & Singtripop. As of 2016 it contains 3 species, all from southeast Asia.
Disnyssus is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2016 it contains 2 species, both from Queensland.
Kolora is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2016 it contains 4 species, all found in Queensland.
Leptopicia is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2017, it contains only one species, Leptopicia bimaculata, found in Australia.
Nucastia is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2016 it contains 5 species from Australia.
Ozcopa is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2017, it contains 6 species, all from Queensland.
Ticopa is a genus of spiders in the family Corinnidae. It was first described in 2015 by Raven. As of 2017, it contains 6 species, all from Australia.
Paramedmassa is a monotypic genus of Asian corinnid sac spiders containing the single species, Paramedmassa day. The genus was erected by C. Jin, H. L. Zhang, and F. Zhang in 2019 for a single species previously placed in Allomedmassa. The fourth section of the first legs can have anywhere from five to ten spines, depending on locale. Jin and Zhang propose that the morphological variance could indicate multiple species, but more individuals will need to be found and studied before a solid conclusion can be reached.
