Neocorynura electra is an extinct species of sweat bee in the Halictidae genus Neocorynura. N. electra is named from the Latin electrum meaning "amber". The species is known from a single female specimen, the holotype, deposited in the American Museum of Natural History, and which was first studied by Dr. Michael S. Engel. He published his type description in the Journal of the New York Entomological Society volume 103 published in 1995. Extremely well preserved in early Miocene Burdigalian stage Dominican amber from the island of Hispaniola, the female individual is very slightly compressed along the legs and head but without apparent destruction of details and the specimen is free from "schimmel", a type of white mold sometimes present on arthropods in amber.
