The primary types of some species of Centris bees described by European entomologists in the 18 and 20 centuries (Hymenoptera: Apidae) Vivallo, Felipe European Journal of Taxonomy 2023 2023-03-27 864 1 27 (Lepeletier & Serville, 1825) Lepeletier & Serville 1825 [482,1105,477,504] Insecta Apidae Centrisamericanorum CoL Animalia Hymenoptera 13 14 Arthropoda genus   Ptilotopusamericanorum Lepeletier & Serville, 1825: 239(junior synonym of  C. americana).    Typedata This species was proposed based on at least two malescollected at an undetermined locality. Moure & Seabra (1960)found two of those specimens in the Spinola collection at MSNT, designating one of them as lectotype, but without providing additional information about its data labels. Unfortunately, the primary type of this species was not available during the preparation of this research.    Typelocality Unknown.  Guillaume-Antoine Olivier Guillaume-Antoine Olivier was a French naturalist and entomologist. He was a very active collector and made a lot of expeditions, he was a very close friend of the Danish naturalist Johan Christian Fabricius, who in 1804 described the genus  Centris. Olivier died in France, aged 58.   Olivier’s  Centrisbee Olivier proposed several new species of bees, but only one in  Centris. The identity of this species was misunderstood, and it was only fixed recently by Vivallo (2016).
