Type data As the previous species, Erichson described this new taxon based on an undetermined number of females. The whereabouts of the syntypes are unknown. Type locality Guyana . Félix Édouard Guérin-Méneville Félix Édouard Guérin-Méneville (1799‒1874) was a French entomologist, famous for his work “ Iconographie du Règne Animal de G. Cuvier ”, a complement to the work published by the French zoologists Georges Cuvier (1769‒1832) and Pierre André Latreille (1762‒1833). Guérin-Méneville founded several magazines of zoology and he was an active member of the Société Entomologique de France . He passed away in Paris, aged 74. Guérin-Méneville’s Centris bee Guérin-Méneville described a variety in the genus Anthophora Latreille, 1803 that actually belongs to Centris . Unfortunately, his contribution was unsuccessful, since the variety he proposed corresponds to a species previously described by Lepeletier in 1841.
