Abstract

A new species of the subgenus Dorypolynema Hayat and Anis of the fairyfly genus Polynema Haliday (Hymenoptera: Mymaridae), is described from Argentina, Brazil, Costa Rica, Ecuador, and Peru. The genus Palaeoneura Waterhouse is recorded from the Nearctic region. Palaeoneura mymaripennis (Dozier) comb. n. from Polynema, previously known only from the USA, is also recorded from the Neotropical region (Guatemala, Honduras, and Panama). Its female is redescribed and the male is described. A new species of Palaeoneura is described from Guatemala and USA (Florida). Chaetomymar tayalum Taguchi from Taiwan (China) is transferred to Palaeoneura as P. tayalum (Taguchi) comb. n.; P. clotho (Debauche) comb. n. and P. oreades (Debauche) comb. n. (both from Democratic Republic of the Congo) are transferred to Palaeoneura from Polynema.
