description: Mecynogea bigibba Simon, 1903
Mecynogea bigibba Simon, 1903: 25 (Female holotype from province of Goyaz [currently encompassing the Brazilian states of Goiás, Tocantins and parts of Minas Gerais and Mato Grosso do Sul], Brazil, in MNHN 21560, examined by photograph). Roewer 1942: 747; Bonnet 1957: 2745; World Spider Catalog 2017 (complete taxonomic citation history).
Remarks. Mecynogea bigibba was described by Simon (1903) based on a specimen labelled just as “prov. Goyaz”. Although Levi (1997) interpreted the type locality as Goiânia (the capital of the Brazilian state of Goiás), this old locality name corresponds to the Brazilian states of Goiás, Tocantins and parts of the states of Minas Gerais and Mato Grosso do Sul.
Distribution. This species is known mostly from the Brazilian Atlantic Forest, in southern and southeastern Brazil, with only two doubtful records. The first refers to the holotype, a very old specimen with poor locality information. As mentioned above, it could have come from any of four Brazilian states, encompassing areas of humid forest and savannas (the Brazilian Cerrado). Regarding the other doubtful record (Diamantina, Minas Gerais, Levi 1997), we could not examine the specimen, but we suspect it could actually represent M. infelix, which was considered a junior synonym of M. bigibba by Levi (1997). The new records presented herein connect previous records in southern and southeastern Brazil and expands the species northern distribution range by about 1560 km (Fig. 18).
