Echinax is a genus of Asian and African corinnid sac spiders first described by Christa L. Deeleman-Reinhold in 2001. [2]
As of April 2019 [update] it contains twelve species: [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.
Clubiona is a genus of sac spiders that was first described by Pierre André Latreille in 1804.
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.
Utivarachna is a genus of Asian araneomorph spiders in the family Trachelidae first described by Kyukichi Kishida in 1940. It was largely ignored until Christa L. Deeleman-Reinhold revised the sac and ground spiders in 2001, transferring some species from Trachelas and adding several new ones. The genus was further expanded in 2014 and 2015.
Nusatidia is a genus of Asian sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Koppe is a genus of liocranid sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Malamatidia is a genus of Southeast Asian sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Pristidia is a genus of Asian sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Pteroneta is a genus of sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Scopalio is a monotypic genus of Indonesian sac spiders containing the single species, Scopalio verrens. It was first described by Christa L. Deeleman-Reinhold in 2001, and has only been found in Indonesia.
Castoponera is a genus of Southeast Asian corinnid sac spiders first described by Christa L. Deeleman-Reinhold in 2001.
Medmassa is a genus of corinnid sac spiders first described by Eugène Simon in 1887 under the name "Megaera", later renamed because "Megaera" was already in use as a synonym of the reptile genus Trimeresurus.
Sesieutes is a genus of Asian liocranid sac spiders first described by Eugène Simon in 1897. It was briefly transferred to the Corinnidae in 2013, but was returned a year later due to its similarity and relation to Phrurolithus.
Tamin is a genus of Indonesian long-legged sac spiders first described by Christa Deeleman-Reinhold in 2001. As of April 2019 it contains only two species.
