Chikunia is a genus of Asian comb-footed spiders that was first described by H. Yoshida in 2009. [2] These spiders are small, often dark or orange colored. This species can be found in solidarity, though they can also be found in colonies. [3]

Colonies

The species C. bilde and C. nigra are unique for spiders, as they are capable of forming intra-species colonies, both spiders being each others closest relative. Both species care for their young, and are thought to do the same to their neighbor's young. These colonies can be around 100 strong, with each adult keeping a distinct territory inside the colony. Another question raised by this unique arrangement, is the fact that they are both genetically distinct species. [3] [4]

Species

As of May 2020 it contains three species, found in Asia: [1]

Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.

<i>Argyrodes</i> Genus of spiders

Argyrodes, also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864. They occur worldwide, and are best known for their kleptoparasitism. They can spin their own webs, but tend to invade and reside in their hosts' webs. This relationship can be commensal or even mutual if the dewdrop spider feeds on small trapped insects that are not eaten by the host. Some species can even prey upon the host.

<span class="mw-page-title-main">Social spider</span> Spiders that form long-lasting aggregations

A social spider is a spider species whose individuals form relatively long-lasting aggregations. Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies.

<i>Parasteatoda</i> Genus of spiders

Parasteatoda is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. The name is a combination of the Ancient Greek "para-" (παρά), meaning "near" or "next to", and the theridiid genus Steatoda. The Japanese name for this genus is O-himegumo zoku.
