Creugas is a genus of corinnid sac spiders first described by Tamerlan Thorell in 1878. [2]
As of April 2019 [update] it contains twenty species in the Americas from Mexico to Brazil, and one (C. gulosus) with a cosmopolitan distribution: [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.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena.
Theridion is a genus of tangle-web spiders with almost 600 described species around the world. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Metepeira is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1903. The name is derived from the Ancient Greek μετά and the obsolete genus name Epeira, denoting a genus similar to Epeira.
Linyphia is a genus of dwarf spiders that was first described by Pierre André Latreille in 1804. The name is Greek, and means "thread-weaver" or "linen maker".
Ctenus is a genus of wandering spiders first described by Charles Athanase Walckenaer in 1805. It is widely distributed, from South America through Africa to East Asia.
Trechalea is a genus of spider in the family Trechaleidae, found in the United States to Peru and Brazil.
Corinna is a genus of corinnid sac spiders first described by Carl Ludwig Koch in 1841. They are found in Mexico and south to Brazil, and with selected species found in Africa.
Elaver is a genus of sac spiders first described by Octavius Pickard-Cambridge in 1898.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
