Taxonomy

The genus was first described by Josef Anton Maximilian Perty in 1833 from the type species Actinopus tarsalis found in Brazil.[2][3] The genus name comes from Ancient Greek ἀκτίς (aktís), meaning "ray, beam", and πούς (poús), meaning "foot", and thus, "ray foot".[2] It is a senior synonym of Aussereria, Closterochilus, Pachyloscelis, and Theragretes.[4][5][6]

Venom

The few reported bites from Brazil resulted in no symptoms, indicating that they can deliver dry bites or small amounts of venom.[7] However, they should be treated with caution due to some reports of bites causing local pain and muscle contractions.[8] These spiders also have a low venom yield; Actinopus crassipes for example has a mean venom yield of 0.09 mg.[9]

Species

As of September 2025, this genus includes one hundred species:[1]
