Actinopus

Actinopus is a genus of mygalomorph spiders in the family Actinopodidae. As such, they live in soil-covered burrows with a hinged top. The males wander about in search for females, which stay in their burrow for most of their life.

Taxonomy

The genus was first described by Josef Anton Maximilian Perty in 1833 from the type species Actinopus tarsalis found in Brazil. The genus name comes from Ancient Greek (aktís), meaning "ray, beam", and (poús), meaning "foot", and thus, "ray foot". It is a senior synonym of Aussereria, Closterochilus, Pachyloscelis, and Theragretes.

Venom

The few reported bites from Brazil resulted in no symptoms, indicating that they can deliver dry bites or small amounts of venom. However, they should be treated with caution due to some reports of bites causing local pain and muscle contractions. These spiders also have a low venom yield; Actinopus crassipes for example has a mean venom yield of 0.09 mg.
