Comments. Possibly its type locality is wrong (Central America), Gorochov also doubts it in the original description, accompanying with a question mark (?). Gorochov (2001b) included this species in Neolutosa , knowing only one female, which in her habitus generally coincides with the diagnosis of the genus. But the character of the emarginate female subgenital plate must be reevaluated, since some females of undescribed species of Lutosa also have the emarginate subgenital plate.

We studied two females from Ilhéus , Bahia ( Brazil) ( Fig. 14 ), these females fit the diagnostic characters of the species, so we do not believe in the presence of this species in Central America. This situation probably occurred due to an error in the holotype label. For now, it is necessary to study males from the collection area of females, to fully corroborate the generic status of the species. For the females studied here, it can be confused and a reader may think that they are two different species due to the shape of the subgenital plate. However, one of the females has the subgenital plate in a normal position ( Fig. 14F ), and the other female has it opened (lowered), exposing the genital chamber ( Fig. 13G ). This could be confusing at first glance, and that is why we clarify it here .

Specimens examined. 2 Females. Brazil, Bahia, Ilhéus. A female collected in 06–08.VIII.2021 and another in 02–04.XI.2021, both in pitfall. Ombrophilous forests. Albuquerque, F. & Souza ( MPEG) .

Measurements of females studied (in mm.). LB: 29–30.3. Pr: 10.4–10.7. HF: 28.9–30.2. HT: 27.4–30.6. Ov: 15.6–17.
