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 triangulate cobweb spider is a common spider in the genus Steatoda. It is well known for the triangle-shaped pattern on the dorsal side of its abdomen.
Missulena is a genus of mygalomorph spiders in the family Actinopodidae. It was first described by Charles Walckenaer in 1805, and is a senior synonym of Eriodon. M. tussulena is found in Chile, but the rest are indigenous to Australia. They are sometimes referred to as "mouse spiders" from the now-disproven belief that they dig deep burrows similar to those of mice. Scotophaeus blackwalli is also called a "mouse spider", but it is smaller and not closely related.
Leptorchestes is a genus of jumping spiders in the family Salticidae. As in several other genera of salticids, it mimicks ants.
Battalus is a genus of Australian corinnid sac spiders first described by Ferdinand Karsch in 1878. Originally placed with the ground spiders, it was moved to the Corinnidae in 2015.
Anasaitis canosus, previously of the genus Corythalia, is a small jumping spider that can typically be found atop leaf-litter or man-made structures such as fences and exterior walls. This species is more commonly known as the twin-flagged jumping spider due to the two pennant shaped markings on the dorsal side of the cephalothorax. Typical of the genus Anasaitis, this species has iridescent setae ("scales") which may appear white, green or pink which create the "flags" as well as patches on the male pedipalps used in courtship and intraspecific signaling. This species is roughly 5 to 6 mm in length. A. canosus ranges from Mexico to South Carolina along the Gulf of Mexico.
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.
Spariolenus is a genus of Asian huntsman spiders that was first described by Eugène Louis Simon in 1880. They are found in the Middle East reaching 15-16cm.
Nyssus is a genus of corinnid sac spiders first described by Charles Athanase Walckenaer in 1805.
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.
Mexcala kabondo is a species of jumping spider in the genus Mexcala that lives in the Democratic Republic of the Congo, Malawi and Tanzania. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. It mimics ants and ant-like wasps, living alongside and preying upon them. The spider is medium-sized, with a brown to blackish carapace between 3.0 and 3.3 mm long and an abdomen between 4.0 and 5.3 mm long that is nearly black with a pattern of three black bands and four orange patches. It is typical of the genus. The internal structure of the female copulatory organs is the most distinguishing feature of the species. The male has not been described.
Mexcala fizi is a species of jumping spider in the genus Mexcala that lives in Democratic Republic of the Congo and Tanzania. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. It mimics ants and ant-like wasps, living alongside and preying upon them. The spider is medium-sized, with a dark browncarapace between 2.7 and 2.9 mm long and a brown abdomen between 3.1 and 3.4 mm long. The female has not been described.
Mexcala namibica is a species of jumping spider in the genus Mexcala that is endemic to Namibia, after which it is named. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. It mimics ants, living alongside and preying upon them, particularly Camponotus detritus. Only the male has been described. It is a medium-sized spider, with ablackish carapace typically 3.3 mm (0.13 in) long and a reddish-orange abdomen typically 4.1 mm (0.16 in) long. It is similar to others in the genus, but can be distinguished by the dark pattern on its abdomen, consisting of a stripe to the front, two patches in the middle and black chevrons at the back.
Mexcala signata is a species of jumping spider in the genus Mexcala that lives in Kenya and Tanzania. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. It mimics ants and ant-like wasps, living alongside and preying upon them. Only the female has been identified. The spider is medium-sized, with a dark carapace typically 3.2 mm (0.13 in) long and a black abdomen typically 3.3 mm (0.13 in) long. The abdomen has a distinctive pattern with a white stripe to the front, dark shape in the middle and orange marks on the sides, after which it is named. It can be most distinguished from other spiders in its genus by its short seminal ducts.
Storena is a genus of ant spiders first described by Charles Athanase Walckenaer in 1805.
Kintaqa is a genus of southeast Asian cellar spiders erected in 2018 for five species moved from Pholcus after a molecular phylogenetic study. They are medium-sized spiders, distinguished by their unique enlarged shape of fourth segment of pedipalps.
Meraha is a genus of southeast Asian cellar spiders. The genus was erected in 2018 for two species transferred from Pholcus after a molecular phylogenetic study of Pholcidae. The name is derived from the Malay "merah", meaning "red", referring to the reddish-orange hue of pedipalps. They are average sized cellar spiders with a cylindrical abdomen, and they build domed webs .5 to 2 metres above the ground.
Zodarion wesolowskae is a species of ant spider in the genus Zodarion that lives in Morocco. The species was first described in 2020 by Souâd Benhalima and Robert Bosmans. Only the male has been described, although Benhalima and Bosmans suggest that the female could be one of the spiders described as Zodarion trianguliferum. The spider is small, typically 3.4 mm (0.13 in) long, with a plain brown to dark brown carapace and a black abdomen which has faint white stripes. The spider is a member of the mostafai group within the genus, which lack a tooth at the end of the embolus. It can be further distinguished from other members of the genus by its very long and thin tibial apophysis. The genus Zodarion is known to use ant mimicry for both defence against predators and to deceive ants to prey on them. This attribute could be used as a form of biological pest control.
Castianeira swiftay is a species of sac spider in the family Corinnidae. It is found in Costa Rica, and named in honor of the American singer-songwriter Taylor Swift.
