Diagnosis. Males of Patrera recentissima are easily distinguished from the remaining species by the filiform median apophysis and embolus originating markedly from the base of the tegulum, forming a wide curvature in the male palp (Figs 19C, 20A, 21B, C). Females are diagnosed by the epigynum with triangular hood and copulatory ducts comma-shaped as seem by transparence (Figs 19F, G, 20C, D, 21F).
