Description of a New Species of Myrmecina (Hymenoptera: Formicidae: Myrmicinae) from the Southeastern United States.

Myrmecina davisoni sp. nov. (Hymenoptera: Formicidae: Myrmicinae) is described from Alabama, USA based on specimens from a mixed colony that included one M. davisoni queen with workers and several Myrmecina americana Emery workers without a queen, suggesting that M. davisoni may be parasitic. Photographs of the worker and queen are provided and an identification key separating this species from the two other described North American species, M. americana and Myrmecina cooperi Deyrup, is given.
