Paratrechalea julyae Silva & Lise 2006: 72 , figs 1–6 (Male holotype, Fazenda Paissandu, Mucuri,Bahia, Brazil, 15.VI.1979, A. C. Niella leg., deposited in MCN 10851, examined).

Diagnosis. The female of P. julyae is similar to P. saopaulo Carico, 2005 (see Carico 2005: fig. 32) and P. wygodzinskyi (Soares & Camargo, 1948) (see Silva et al. 2006: fig. 19) by the projected shape of the scape of the middle field of epigynum, but can be distinguished by the longer and triangular shape of the scape and the excavated lateral lobes (LL) ( Figs 4 , 6 ).

Description. Male. Described by Silva et al., 2006: 72, figs 1–6. New remarks: male palpus with excavated spur on tip of guide of median apophysis ( Figs 7–9 ) and prominent retrolateral tibial apophysis ( Figs 10–11 ).
