Anyphaena virgata Keyserling, 1891: 92, fig 54 (Syntypes two males and four females from Fazenda Calvário, Serra Vermelha, Itaocara (21°40’44”S; 42°4’55”W), Rio de Janeiro, Brazil, Prof. Göldi leg., deposited in BMNH 1890.7.1.595-600, examined). Lectotype male in BMNH 1890.7.1.595 and paralectotypes one male and four females in BMNH 1890.7.1.626–630, here designated).
Teudis virgatus: Petrunkevitch, 1911: 519.
Patrera virgata: Brescovit, 1997: 33.
Other material examined. None.
Diagnosis. Patrera virgata resembles P. concolor by the male having conspicuous retrolateral tibial apophysis and flattened median apophysis in the male palp (as in Figs 17C, D, 18A, B), and having large hood and broad atrium in the female epigynum (as in Figs 17F, 18C). They differ by the inverted U-shaped sperm duct in the tegulum and by the retrolateral tibial apophysis enlarged at tip and presenting two laminar, triangular projections (Figs 7A, B) in the male palp. Females differ by the epigynum with semicircular hood and part of the copulatory ducts ventrally arched, shown by transparency (Figs 7C, D).

Palp: tibia straight, slightly longer than the cymbium; cymbium oval; tegulum oval; tegular projection short, almost completely covered by the tegulum; elongated, subapical median apophysis; slender embolus, originating at the base of the tegulum (Figs 7A, B).
