Parachemmis is a genus of corinnid sac spiders first described by Arthur M. Chickering in 1937 as a genus of ground spiders. [2] It was transferred to Liocranidae in 1969, [3] and to Corinnidae in 1994. [4]
As of April 2019 [update] it contains four species in Central and South America: [1]
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.
Bryantella is a genus of jumping spiders that was first described by Arthur Merton Chickering in 1946. As of June 2019 it contains only two species, found only in Brazil, Argentina, and Panama: B. smaragda and B. speciosa. This genus was named in honour of Elizabeth B. Bryant.
Masteria is a genus of curtain web spiders that was first described by L. Koch in 1873. They occur in the tropics of Central to South America, Asia and Micronesia, with one species found in Australia. M. petrunkevitchi males are 4 millimetres (0.16 in) long and females are 5 millimetres (0.20 in) long. M. lewisi, M. barona, and M. downeyi are slightly smaller and have only six eyes.
Myrmecotypus is a genus of ant mimicking corinnid sac spiders first described by O. Pickard-Cambridge in 1894. Species mainly occur from Panama to Mexico, with one species found in the United States, and one in Argentina.
Cheiracanthiidae is a family of araneomorph spiders first described by Vladimir Wagner in 1887. The synonym Eutichuridae was used for a long time, but Cheiracanthiidae has priority. The largest genus currently recognized as belonging to this family is Cheiracanthium, which has previously been placed in both the Clubionidae and the Miturgidae.
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.
Calamoneta is a genus of southeastern Asian spiders within the family Cheiracanthiidae. It was originally placed in the Miturgidae, but it was moved by Ramírez in 2014. It was named and first described by Christa Deeleman-Reinhold in 2001. The name is derived from the Greek "kalamos", meaning "something woven". There are two species in this genus, C. djojosudharmoi – the type species – and C. urata.
Abapeba is a genus of Central and South American corinnid sac spiders first described by A. B. Bonaldo in 2000.
Ecitocobius is a monotypic genus of South American corinnid sac spiders containing the single species, Ecitocobius comissator. It was first described by A. B. Bonaldo & Antônio Brescovit in 1998, and has only been found in Brazil.
Ianduba is a genus of South American corinnid sac spiders first described by A. B. Bonaldo in 1997.
Methesis is a genus of South American corinnid sac spiders first described by Eugène Simon in 1896. Originally placed with the ground spiders, it was moved to Corinnidae in 1969. As of April 2019 it contains only two species.
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.
Simonestus is a genus of corinnid sac spiders first described by A. B. Bonaldo in 2000.
Tapixaua is a monotypic genus of South American corinnid sac spiders containing the single species, Tapixaua callida. Both male and female were first described by A. B. Bonaldo in 2000, and has only been found in Brazil and Peru.
Tupirinna is a genus of corinnid sac spiders first described by A. B. Bonaldo in 2000.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
Strotarchus is a genus of araneomorph spiders in the family Cheiracanthiidae that was first described by Eugène Louis Simon in 1888. Originally added to the Clubionidae, it was moved to the Miturgidae in 1967, and to the Cheiracanthiidae in 2014. It is considered a senior synonym of Marcellina and Coreidon.
Erendira is a genus of corinnid sac spiders first described by A. B. Bonaldo in 2000.
Serendib is a genus of Southeast Asian corinnid sac spiders first described by Christa L. Deeleman-Reinhold in 2001. As of April 2019 it contains only three species.
Bucliona is a genus of sac spiders first described by Pierre L.G. Benoit in 1977. As of November 2021 it contains only three species: B. dubia, B. jucunda, and B. kirilli. It was synonymized with Clubiona in 1997, but was elevated back to genus in 2021. The type species was originally described under the name "Clubiona dubia".
