Ariadna levii— Grismado (2008: 345, in part, only the ♀ paratype, misidentification) . 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.
