Brachymenes is a small neotropical genus of potter wasps currently containing two species, the primarily Andean species B. wagnerianus and the lowland species B. dyscherus. The first wasp of this species was collected by the German natural scientist Moritz Wagner (born at Bayreuth, Bavaria, on 3 October 1813) during his expedition from Panama over Colombia to Ecuador between 1858 and 1859. The holotype specimen later was described by the nature scientist Henri de Saussure from Geneva, who named the new-found wasp Eumenes wagnerianus in honour of its finder. In 1961, the Italian biologist Antonio Giordano Soika, during his revision of the Eumenidae family, founded, at the 11th Congress of the Entomological Society in Vienna, the new genus Brachymenes and described the new species Brachymene
