Ariadna  tovarensis— Petrunkevitch (1911: 131).— Bonnet (1955: 738).— Beatty (1970: 472).— World Spider Catalog (2018).

Diagnosis. Ariadna tovarensis  is similar to A. caparao  n. sp. due to the elongated lobes of the anterior receptaculum, but differs by presenting the ventral lobe almost straight and shorter than the DL ( Fig. 26E ‒FView FIGURE 26).

Palps yellow, darkening gradually in distal direction. Legs yellow, with pairs I ‒II darker ( Fig. 26C ‒DView FIGURE 26). Abdomen light grey ( Fig. 26A ‒BView FIGURE 26). Total length 7.4; carapace 3.04 long, 2.16 wide. Legs: robust and coated with setae; legs I ‒II with ventro-prolateral and ventro-retrolateral tibial macrosetae of similar size, and metatarsal macrosetae of different sizes ( Fig. 26C ‒DView FIGURE 26). Leg formula: I-II-IV-III. Leg measurements: I, femur 2.24, patella 0.96, tibia 1.6, metatarsus 1.52, tarsus 0.6, total 6.92; II, 2.0, 0.96, 1.6, 1.4, 0.52, 6.48; III, 1.6, 0.76, 1.0, 0.92, 0.44, 4.72; IV, 1.92, 0.96, 1.44, 1.12, 0.52, 5.96. Macrosetae: I, femur D0-0-0-0- 0-2-0, P0-0-0-0-2-1-0; tibia P0-1-0-1-1/0-1-0, vp1-0-1-0-1-0-1, vr1/2-0-1-0-1-0-1, R1-0-1-0-1-0-1; metatarsus vp1-0/1-1-1-1-1-1, vr1-0-1-1-0-1-1 ( Fig. 26C ‒DView FIGURE 26); II, femur D0-0-0-0-0-2-0, P0-0-0-0-0/1-1-0; tibia P0-0/1-0-1-1/ 0-1-0, vp0-0-0-1/0-0-1-1, vr1-0-1-0-1-0-1, R0-0-1-0-1-0-1/0; metatarsus vp1-0-1-1-0-1-1, vr1-0-1-1-0-1-1; IV, metatarsus vr metatarsal comb with 4 macrosetae. Internal genitalia: anterior receptaculum with glandular plate located in the median region, and expanded in its proximal region ( Fig. 26E ‒FView FIGURE 26).
