Anelosimus
cobweb spiders
Anelosimus is a genus of cobweb spiders (Theridiidae) renowned as a model system for studying the evolution of sociality in arachnids. The genus contains approximately 75 species exhibiting the full spectrum of social organization, from solitary to highly social (quasisocial). Eight quasisocial species have been documented, more than any other spider genus. Social species such as Anelosimus eximius form massive communal webs housing tens of thousands of individuals, while solitary species occur at higher altitudes and latitudes. The genus is cosmopolitan, with significant diversity in the Americas, Madagascar, and Australasia.

The type species, Neottiura bimaculata, has the widest distribution, spanning from North America across Eurasia to Japan.

The genus contains approximately 27 species, with the majority distributed in the Americas from the United States through Central America to Brazil, and a smaller number of species in East Asia including China, Japan, Korea, and Laos. One species, S. satpudaensis, has been recorded from India.
