Synonymy. Giroti & Brescovit (2011) transferred Segestria pusilla to Ariadna as nomen dubium, since the unavailability of the holotype and the indefiniton of the type-locality. Considering characters from Nicolet's description, as the carapace reddish brown and light yellow legs, together with the distribution of Ariadna maxima in Chile, this species is here proposed as a junior synonym of A. maxima. Grismado (2008) described a female paratype of Ariadna levii, depicting the female internal genitalia of a non-type specimen. After the examination of those specimens, we detected that the paratype actually is Ariadna maxima, due to coloration, macrosetae pattern and leg size in relation with body size. The diffuse abdominal pattern presented by the paratype is usual to A. maxima. On the other hand, the described and depicted genitalia in Grismado (2008: 344, figs 6D‒E) belongs to an A. levii specimen.The oddest synonym proposal involves the African species Ariadna ashantica Strand, 1916. In his work, Strand (1916) described this species based on a male and the cephalothorax and legs of a possible female from Ashanti region, in Ghana. After the examination of the type specimens, we identified them as A. maxima, based on the morphology of the male palp and metatarsi I. The occurrence of A. maxima in a locality so far away of the type locality is rather odd, but it could have occurred by anthropic introduction or even human-error handling and labeling the vial in the museum.

Diagnosis. Ariadna maxima is similar to A. araucana and A. lalen n. sp. due to the morphology of the male metatarsi I and leg macrosetae pattern of females, but differ by the presence of a male metatarsi I sinuous in lateral view (Fig. 14C‒D), and palps rounded, with the midportion and embolus with similar size (Fig. 15A‒B); females differ by the anterior receptaculum billobulated (Figs 9B, 15C‒D), with a large median glandular ducts plate and interpulmonary fold with a dorsal median membranous crack (Fig. 9B).
Description. Male (IBSP 166780). Carapace and chelicerae dark reddish brown (Fig. 14A). Endites brownish orange; labium dark brownish orange. Sternum brownish orange with darker margins, and four pair of fainted dark marginal areas (Fig. 14B). Palps brownish yellow (Fig. 15A‒B). Legs brownish orange, with pairs I‒II darker and with dark pigment forming diffuse rings in the distal region of the metatarsi and tarsi (Fig. 14C‒E). Abdomen grayish, lighter ventrally, and with a diffuse dark dorsal pattern (Fig. 14A‒B). Total length 10.0; carapace 5.2 long, 3.6 wide. Palps: tibia incrassated, with the dorso-ventral diameter equal to the bulb; cymbium with a dorsal chemosensory patch; bulb sub-rectangular, mid-portion slightly shorter than the embolus; embolus thickened, slightly curved, and ending abruptly (Fig. 15A‒B). Legs: slender and coated with setae (Fig. 14C‒E); tarsal brush of putative chemosensory setae present in legs in pairs I‒IV, but reduced in legs I, III‒IV; metatarsus I sinuous, ventrally bent in lateral view (Fig. 14C‒D).
