Diagnosis
Phoneutria pertyi is most similar to P. nigriventer and P. eickstedtae sp. nov. Females differ by having several basal sulci in the epigynal lateral apophysis (Fig. 15), whereas these are absent in P. n i g r i v e n t e r (Fig. 13) and reduced in P. eickstedtae sp. nov. (Fig. 16). Males have the pedipalp tibia longer or similar in length to the cymbium and the apex of embolus curved and hook-like in shape (Figs 26, 30), in contrast P. nigriventer and P. eickstedtae sp. nov. in which the tibia is shorter than the cymbium and the embolus is straight (Figs 36, 39).

Remarks
In her revisionary work, Eickstedt (1981) confirmed the validity of P. pertyi after examining the holotype and other specimens from the type locality. Subsequently, Simó and Brescovit (2001) synonymised P. p e r t y i with P. nigriventer arguing that characters presented in the original description such as the equal length of legs I and IV and the lack of an anterior truncation of the epigyne were not of diagnostic value. They also perceived that (p. 73) "the morphology of the epigynum of the holotype of this species corresponds with P. nigriventer ". In contrast, we consider P. pertyi a valid species based on the distinct morphology of male and female genitalia: males, unlike P. nigriventer, have the embolus tip with an accentuated curvature, the tegulum is as wide at its base as at the median region, and the median tegular apophysis is as wide as long, with the sperm duct curved close to the embolus base (Figs 26, 30). The epigyne of females have a convex middle field, the epigynal lateral apophyses are wide with many narrow basal sulci (Figs 7, 15), and the spermathecae have a retrolateral projection (Fig. 11). The wide epigynal lateral apophyses with basal sulci are features found also in the Amazonian species of Phoneutria, suggesting close affinities with these species. Additionally, immature spiders do not change their colour during development, in contrast to both P. n i g r i v e n t e r and P. keyserlingi.
Distribution
Atlantic rainforest in Brazil, from the extreme southeast of the State of Bahia, eastern parts of Minas Gerais, Espírito Santo and northwestern Rio de Janeiro (Fig. 68).
