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

The genus name, "Heteralocha", derives from Ancient Greek "ἕτερος" "different" and "ἄλοχος" "wife". It refers to the striking difference in bill shape between male and female. The specific name, "acutirostris", derives from Latin "acutus", meaning "sharp pointed", and "rostrum", meaning "beak", and refers to the beak of the female. John Gould described the huia in 1836 as two species: "Neomorpha acutirostris" based on a female specimen, and "N. crassirostris" based on a male specimen—the epithet "crassirostris" derives from the Latin "crassus", meaning
