Other material examined. BRAZIL. Santa Catarina: Rancho Queimado (27°40′22″S 49°1′19″W), 1♂, 2♀, 8– 14.X.1994, L.A. Moura & A.B. Bonaldo leg. (IBSP 212646).

Diagnosis. Patrera concolor resembles P. virgata by 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). Carapace yellowish orange; chelicerae yellow; labium and endites orange. Sternum yellow with orange borders. Legs yellow except coxae I, orange.

Palp: tibia straight, as long as cymbium; cymbium oval; tegulum oval, with sperm duct sinuous at third basal area, forming an elongated “S-shaped”; subtegular projection short, covered by the tegulum; subdistal, flattened median apophysis, slightly curved at apex; slender embolus, with narrow base (Figs 17C–E, 18A, B).
