Moura& A.B. Bonaldoleg. (IBSP 212646).   Diagnosis.  Patrera concolorresembles  P. virgataby the conspicuous retrolateral tibial apophysis and flattened median apophysis in the male palp (as in Figs 7A, B), and by having large hood and broad atrium in the female epigynum (as in Figs 7C, D). They differ by the sperm duct forming a sinuous route in the tegulum and retrolateral tibial apophysis tapering to the distal region, with a very wide base in the male palp. ( Figs 17C–E, 18A, B). Females can be distinguished by the epigynum with large, triangular hood and parallel, narrow ventral copulatory ducts, as shown by transparency ( Figs 17F, G, 18C, D).   Description. Male(IBSP 212646).
