The fauna of Ceraphronoidea in Poland is exceptionally poorly known; only eleven species of Ceraphronidae and five of Megaspilidae have been recorded so far. The occurrence of another species, Aphanogmus terminalis (FÖRSTER) (Ceraphronidae) is reported here, on the basis of a male specimen reared from a gall of Rhabdophaga sp. (Cecidomyiidae) collected near Poznań, Western Poland. This minute wasp has been known so far only from Switzerland, Sweden, Denmark, Finland, Ireland and Romania. KEY WORDS: Hymenoptera, Ceraphronidae, new record, Poland. Introduction The Ceraphronidae and Megaspilidae are relatively small families of Ceraphronoidea, together comprising over 600 nominal species. They are endo- and ectoparasitoids of Diptera, Hemiptera, Neuroptera and Thysanoptera or hyperparasitoids of Hymenoptera. The majority of these wasps are minute in size, rarely exceeding 2 mm, and although they are commonly collected using standard methods, e.g., by using sweeping nets or sifting leaf litter, they are unpopular among entomologists and knowledge of their distribution even in Europe is exceptionally fragmentary. Merely nine species of Ceraphronidae and five of Megaspilidae known to occur in Poland were listed by GARBARCZYK (1997), but the recently updated
