Ariadna dubia Mello-Leitão, 1917: 82 View in CoL (♀ holotype from Pinheiro (actually Piraí, Pinheiral [22°30'46"S, 44°00'03"W], Rio de Janeiro, Brazil, E. Brito leg., should be deposited in MNRJ 1452, lost).— Beatty (1970: 483, as nomem dubium).— Moreira et al. (2010: 61).— NEW SYNONYMY.
Synonymy. Mello-Leitão (1917) described A. dubia based in a dried and pinned specimen, with a deformed and seared abdomen. Beatty (1970), due to the unavailability of the holotype and the poor description of Mello-Leitão, treated it as nomem dubium. There are two species registered to the type-locality of A. dubia : Ariadna boliviana Simon, 1907 and Ariadna obscura ( Blackwall, 1858) . According to the macrosetae pattern presented by Mello-Leitão (1917) in A. dubia 's original description, the tibiae I‒II presents 2-2-2-2 pattern (vp1-0-1-0-1-0-1, vr1-0-1-0-1-0-1) and metatarsi I and II with seven pairs of macrosetae. This macrosetae pattern is consistent with the one from A. boliviana , and differs from A. obscura . Based in the characters presented by Mello-Leitão (1917), A. dubia is considered junior-synonymy of A. boliviana .

Diagnosis. Ariadna boliviana is similar to A. isthmica , A. ipojuca n. sp. and A. gaucha n. sp. due to the morphology of male palp ( Figs 37A‒B View FIGURE 37 , 44A‒B View FIGURE44 , 58G‒H View FIGURE 58 , 61A‒B View FIGURE 61 ), metatarsi IV ( Figs 36F View FIGURE 36 , 43F View FIGURE 43 , 58F View FIGURE 58 , 60F View FIGURE 60 ), and leg macrosetae pattern of females, but differ by the presence of males with sinuous metatarsi I, with a marked bend in the proximal region ( Fig. 36C‒E View FIGURE 36 ); females differ from these species, except A. gaucha n. sp., by the presence of a ventral lobe longer than the dorsal one; it differs from A. gaucha n. sp. by the less sinuous ventral lobe ( Figs 10A‒C View FIGURE 10 , 37C‒D View FIGURE 37 ).
Description. Male (IBSP 152775). Carapace and chelicerae brownish orange ( Fig. 36A View FIGURE 36 ). Endites orange; labium dark orange. Sternum orange with darker margins, and three pairs of dark marginal areas, the hind one fainted ( Fig. 36B View FIGURE 36 ). Palps light orange ( Fig. 37A‒B View FIGURE 37 ). Legs brownish orange, pairs I‒II darker, with the femur, patella and tibia marbled with dark pigment, and dark diffuse rings in the distal region of metatarsus ( Fig. 36C‒F View FIGURE 36 ).
