B. costipennis Ohaus, 1928: 403

syn. Bolax costipennis Machatschke, 1974: 249 . NEW HOMONYM, NEW SYNONYM

BRAZIL: Mato Grosso, Rio de Janeiro, São Paulo Note: Machatschke (1974b) is credited with the name B. costipennis (e.g., Frey 1976a), but Ohaus (1928) properly described the species. Erroneously, Machatschke (1974b) stated that he was newly describing a species using Ohaus’ labeled specimens and maintaining Ohaus’ given name for that species. Machatschke was unaware that Ohaus (1928) had described the species. According to these publications, Machatschke and Ohaus used the same specimens for the type series. According to Article 60.2 ( ICZN 1999), if the rejected junior homonym has one or more potentially valid synonyms, the oldest of these names is the valid name of the taxon ( B. costipennis Ohaus in this case).
