Nesagapostemon Nesagapostemon Nesagapostemon is an extinct monotypic genus of sweat bee in the Halictidae subfamily Halictinae. At present, it contains the single species "Nesagapostemon moronei". The genus name "Nesagapostemon" is derived from a combination of the Greek "nesos", meaning "island", and "Agapostemon", a very similar genus of halictids which may be related. The species is named in honor of Ettore Morone of Turin, Italy. The species is known from the holotype, a single long female currently in the private collection owned by Morone (catalog number MACT-1172), and which was first studied by Dr. Michael S. Engel. Engel published his type description
