The RTA clade is a clade of araneomorph spiders, united by the possession of a retrolateral tibial apophysis – a backward-facing projection on the tibia of the male pedipalp.[1] The clade contains over 21,000 species, almost half the current total of about 46,000 known species of spider.[2] Most of the members of the clade are wanderers and do not build webs.[3]

Families

In 2005, Coddington included 39 families in a cladogram showing the RTA clade:[4]
