Included genera.

Ephebopus  , Psalmopoeus  , Pseudoclamoris  , Tapinauchenius 


The subfamily Psalmopoeinae  is diagnosed by following synapomorphies as defined by Samm and Schmidt (2010), altered to fit the results presented here:

Psalmopoeinae  can be distinguished from other new world subfamilies (save Aviculariinae  ) by their scopulae on anterior tarsi and metatarsi being extended laterally, giving a spatulate appearance and the absence of leg spines on tibiae and metatarsi. They differ from Aviculariinae  (except females of Pachistopelma  and Iridopelma marcoi  Bertani, 2012), as well as Theraphosinae  by the lack of urticating setae on the opisthosoma. Females can further be distinguished from Schismatothelinae  by their completely separated spermathecae. Males can easily be distinguished from those of Aviculariinae  by the presence of two tibial apophyses on leg I.


Legs aspinose or with few apical spines on ventral tibiae and metatarsi; metatarsi and tarsi with scopulae very extended laterally, mainly on anterior legs, giving a spatulate appearance. Spermathecae consisting of two completely separated stalks. Male palpal bulb with long embolus without keels. Males with two tibial apophyses distally on the leg I. Type V urticating setae on prolateral palpal femur present ( Ephebopus  ), or absent (all others). Stridulatory organ present ( Psalmopoeus  , Pseudoclamoris  ) or absent (all others). Legs weakly spined or aspinose, tarsi as broad as, or broader than metatarsi. Arboreal ( Psalmopoeus  , Pseudoclamoris  , Tapinauchenius  ) and fossorial ( Ephebopus  , fossorial only as adults) species.
