''Theridion'' is a genus of tangle-web spiders with a worldwide distribution. Notable species are the

(''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.

Identification

Spiders in this genus are about as long or longer then they are wide. Their chelicerae have two or less teeth on the front edge and none on the back edge. The front leg is the longest in both genders, but the next longest is the second leg in males and the fourth leg in females. The

epigyne The epigyne or epigynum is the external genital structure of female spiders. As the epigyne varies greatly in form in different species, even in closely related ones, it often provides the most distinctive characteristic for recognizing species. ...

can vary, but the pedipalp has a median apophysis and a

colulus Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates. In certain groups of diatoms it refers to microscopically punctured regions of the frustule, or o ...

is absent from both genders. In several species, the males have mastidia (projections) on the chelicerae. ''Theridion'' has the anterior eye row slightly curved and with a gap between it and the posterior eye row. This distinguishes it from ''

Enoplognatha ''Enoplognatha'' is a genus of comb-footed spiders that was first described by P. Pavesi in 1880. They have both a large colulus and a subspherical abdomen. Males usually have enlarged chelicerae. It is considered a senior synonym of ''Symopagi ...

'', another theridiid genus in which the anterior eye row is almost straight and the gap between eye rows is very small.

Ecology

''Theridion'' build tangle webs, usually under leaves and among vegetation. At night, spiders hang upside-down in these webs. During the day, they hide close by their webs. '' Philodromus cespitum'', a species of running crab spider, preys on ''Theridion'' spiders in European fruit orchards.

Mating

Mating behaviour has been studied in several ''Theridion'' species. It involves pseudocopulation, numerous sperm inductions and copulatory sequences. The male approaches the female to mate, usually in the latter's retreat (a hood-shaped part of the web where the female lives in). Male ''Theridion'' perform contralateral insertions, inserting their left palp into the female's right introductory duct and vice versa for the right palp. Female ''Theridion'' are less aggressive after mating compared to other genera of theridiids.

Species

There are almost 600 described species of ''Theridion''. However, the genus has traditionally been assigned species that lack a colulus and did not fit into other genera ( wastebasket taxon). New species continue to be described on a regular basis. * '' T. abruptum'' Simon, 1884 — North Africa * '' T. accoense'' Levy, 1985 — Israel * '' T. acutitarse'' Simon, 1900 — Hawaii * '' T. adjacens'' (O.
