Bidrag till taxonomi av Polynema Haliday, 1833 och Stephanodes Enock, 1909 (Hymenoptera: Mymaridae) i Sverige

Abstract

Fairyflies (Mymaridae) of the genera Polynema and Stephanodes collected all over Sweden by the Swedish Malaise Trap Project (SMTP) were examined. Five Polynema species were identified as known taxa: P. (Doriclytus) euchariforme Haliday, 1833, P. (Polynema) flavipes Walker, 1848, P. (Polynema) fuscipes Haliday, 1833, P. (Polynema) gracile (Nees ab Esenbeck, 1834), and P. (Polynema) pusillum Haliday, 1833. Stephanodes similis (Foerster, 1847) was the only occurring species for this genus, of which a brief description of Swedish material is provided. The five species of Polynema are redescribed and, in addition, illustrated notes are given on the five unnamed morphospecies of Polynema, in order to provide information for future taxonomic revisions of this genus. A preliminary identification key to all these taxa is provided.
