Resumo

Gonyleptes curvipes Kollar, in C.L. Koch, 1839 has taxonomic problems: it is a primary junior homonym of Gonyleptes curvipes Guerin-Meneville, 1837; the holotype of G. curvipes Kollar was cited twice by Roewer (1913) under two genera, one being a misidentification of an undescribed species and a new combination under Discocyrtus Holmberg, 1878; Koch labeled another unreported specimen as Gonyleptes curvipes. However, this specimen belongs to a species described later by Roewer as D. crenulatus Roewer, 1913. In 2003, Kury transferred G. curvipes sensu Roewer to Discocyrtus and, to avoid homonymic collision with D. curvipes sensu Romer, proposed the new name D. confusus as a replacement name. Discocyrtus confusus was later considered an invalid replacement name and was used to newly describe the species named by Kollar and Koch. Discocyrtus flavigranulatus B. Soares, 1944 is here considered a new junior subjective synonym of G. curvipes Kollar, but which is the next oldest available synonym. Discocyrtus confusus thus also becomes a junior synonym of D.flavigrimulatus. Here we discuss the history and identity of three species of Discocyrtus: D. flavigranulatus B. Soares, 1944; D. crenulatus Roewer, 1913; and D. fenax sp. nov. from Santa Catarina state, Brazil (misidentified by Roewer as D. curvipes). (AU)
