Diagnosis. According to Galiano (1979a) the females of Frigga pratensis are distinguished from the other species of Frigga by the epigyne with triangular anterior fossae, and small, well separated duct entry holes (see Galiano 1979a, figs. 27-29). Slender, cylindrical ducts, directed obliquely outwards in their first section, and then bent at an obtuse angle, with the internal branch long and directed forward, enter the spermathecae through their ventral aspect (see Galiano 1979a, figs. 27-29). According to F. O. PickardCambridge (1901) and Galiano (1979a) the males of Frigga pratensis are distinguished from the other species of Frigga by a palpal bulb that is deeply bilobate at its base ( Figure 40 ), the outer lobe narrowed and prolonged ( Figures 41-42 ). The embolus is slender, elongate, and slightly curving, its point directed outward ( Figures 40, 42 ). The RTA is slender (often stouter), elongate, and deeply bifid at its apex ( Figure 41 ), forming a little fork, sometimes deeply cleft ( Figure 41 ).

Measurements (mm; specimens from Colombia). One male: TL= 7.1; CL= 3.36; CW= 2.9; AL= 3.7; AERW = 1.89; PERW = 1.83; LOQ= 1.46; PMEP =0.24-0.26; eyes of the second row separated from the ALE by 0.26 mm and from the PLE by 0.63mm. Three females: TL= 8.8-9.1; CL= 3.7-3.9; CW= 3.30-3.35; AL= 4.7-5.1; AERW = 1.95-1.97; PERW = 1.93-1.94; LOQ= 1.41-1.43; PMEP =0.26-0.29; eyes of the second row separated from the ALE by 0.35-0.36 mm and from the PLE by 0.46-0.48mm.

Distribution: Frigga pratensis is known from Argentina, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Mexico, Netherlands Antilles, Nicaragua, Panama, and Trinidad.
