| Summary: | A taxonomic revision of Stygnus Perty, 1833, in Colombia was conducted. The new species Stygnus apaporis sp. nov. is described from Lago Taraira, departments of Guaviare and Vaupés in the Colombian Amazonian region. The genus is recorded for the first time in eight Colombian departments: Amazonas, Caquetá, Casanare, Cundinamarca, Guaviare, Meta, Risaralda and Vaupés. New geographic records for S. gerstchi (Roewer, 1963) and comments about its type locality are offered. Two species are recorded for the first time in Colombia: Stygnus nogueirai Pinto-da-Rocha & Tourinho, 2012 (departments of Guaviare and Vaupés) and S. simonis Sørensen, 1932 (department of Amazonas). Some new geographic records of the genus in the Amazon region are presented, and it is recorded for the first time in Ceará state (Brazil) and Madre de Dios department (Peru), with the presence of two unidentified species. Updated distributional maps of the genus in Colombia and South America are offered. Finally, in taxonomic studies of Gonyleptoidea, six longitudinal rows of tubercles have been described on the legs. Here, these rows are identified for a species of the genus Stygnus and an additional row is detected and named.
