diagnosis
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 19 C, 20 A, 21 B, C). Females are diagnosed by the epigynum with triangular hood and copulatory ducts comma-shaped as seem by transparence (Figs 19 F, G, 20 C, D, 21 F).
