Revision of the North American species of Promicrogaster (Hymenoptera, Braconidae, Microgastrinae), with an updated key to all described species in North and Meso America

Abstract

The genus Promicrogaster (Hymenoptera, Braconidae, Microgastrinae) in North America is revised and seven new species are described: floridakeys, gainesvillensis, huachuca, jaymeae, madreanensis, rondeau and virginianus. All but one have so far been found in protected areas of Canada and the USA, with two species collected at rather high altitudes of over 1,600 m.a.s.l. (Arizona, southwestern USA), whereas the other five were found in Eastern North America (southern Ontario and several USA states) at relatively lower altitudes (less than 150 m.a.s.l.). A key to all 31 described species in North and Meso America is provided. A species from Costa Rica previously described in Promicrogaster is here transferred to a different genus as Hypomicrogaster pablouzagai (Fernández-Triana & Boudreault, 2016), comb. nov.
