Anelosimus is a genus of tangle web spider (Theridiidae) described by Eugène Simon, in 1891, from Venezuela.[1] It includes the South American species Anelosimus eximius, which, along with related species, are often studied for insight into spider sociality.
The web of a colony of A. eximius can reach 8 metres (26 ft) into the canopy, and the basket-like retreat at 30 to 150 centimetres (12 to 59 in) above the ground can be up to 3 metres (9.8 ft) in diameter. A colony may house more than 1000 spiders. Other species, particularly those at higher altitudes[2] appear to be solitary or sub-social.
Description
Anelosimus spiders have a notched red or brown band on their abdomen, which is dark when preserved in alcohol. Laterally, the abdomen has a white band and/or white blotches. Specimens range in size from 1.8 to 7.5 millimetres (0.071 to 0.30 in). Individuals in this genus lack a colulus.[3]
