11, see text Synotaxus is a genus of araneomorph spiders in the family Synotaxidae that was first described by Eugène Louis Simon in 1895.

[3][4] Spiders in this genus have a long, green abdomen, which extends to varying degrees beyond the spinnerets.

The posterior lateral spinnerets bear enlarged aggregate gland spigots, and the male pedipalp has a stout patellar spur.

[5] The palpal femur, patella and tibia bear strong, often greatly enlarged, macrosetae.

[3] As of September 2019[update] it contains eleven species, found in South America, Panama, Costa Rica, and on Trinidad:[1] Spiders in this genus are found in the understory of wet forests in South America, where they construct their webs between the leaves of trees or bushes, well above the forest floor.
