Revised Diagnosis. Males of Putaoa species differ from other pimoids in having distinctively large macrosetae on the pedipalpal tibia and/or cymbium ( Figs. 2A, B, E, F ) and by the absence of typical cuspules, such as those found in Pimoa ( Hormiga 1994: figs. 68–70) and Weintrauboa ( Hormiga 2003: figs. 5E, 6D). In addition, Putaoa species lack a median apophysis and have a relatively short and non-filiform embolus ( Figs. 1B , 2D ); the embolus is filiform in many Pimoa ( Hormiga 1994: figs. 86, 102) and Weintrauboa species (Hormiga 2008: figs. 2, 3). In Putaoa the metatarsus I is unmodified, while sinuous in the males of most Weintrauboa species ( Hormiga 2003: figs. 3G–J). Females are diagnosed by their relatively flat epigynum with lateral openings, relatively short copulatory ducts and medial fertilization ducts (the female of P. megacantha remains undescribed).

Phylogenetics. Hormiga & Tu (2008) hypothesized that the monophyly of Putaoa is supported by four unambiguous synapomorphies: large and long macrosetae on cymbium and on male pedipalpal tibiae, absence of a median apophysis and a relatively short, non-filiform embolus. The new species of Putaoa shares all these apomorphies.
