The taxon Microgaster is One Of the oldest genus in Braconidae erected by LΛΤRE ILLE in 1804. The most recent revision Of the species of Microgasterwas constructed by NIXON I9683. Since LATRE ILLE, the interpretation of the taxonomicat Scope of the genus Microgaster WaS reStricted DOm time to time. At present, Microgaster S. Str. iS interpreted in t vo wayS. NIXΟΝ I. c. in includes the species of ΗΜroplitis ΤΗΟΜS. as a SpecieS-group in Microgaster. Contrarily,

a valid genus With iis 3 Europe an species. The distinction Os Microgaster and Hygroplitis, together With further genera Os MicrogaSterini Occurring in Europe, is gi ven in a key. Though NIXΟΝ Ι. c.) has deScribed Severat nexu species of Microgaster Dom Europe, 9 Old Species of Our continent M. campestris TOB., M. fusca ΡΛΡΡ, M. globata L ., M. hungarica SZEPL., M. postica NEES, M. nigricans NEES, M. nobilis ΗΕΙΝΗ ., M. rugosicoxa PAPP, and M. uliginosa TMOΜs.) were omitted in his revision. On the Other harid, Some Species, aSSigne lto it oti the hasis of their ΝW Europe an repreSentatives, are more Or leSS deviat ing froni specimens collected eis ewhere in Europe.
