HANSSON, CH. Taxonomic revision of the Nearctic species of Omphale Haliday (Hymenoptera: Eulophidae). 1996. 78 pp. SEK 140.
Abstract:
The Nearctic members of the genus Omphale Haliday are revised, and a key to the species and other genera of Entedoninae with delimited clypeus are included. The interpretation of Omphale and of species-groups within the genus is different from previous studies due to the dicovery of new characters. 57 species of Nearctic Omphale are regarded as valid of which 35 species are described as new.
Six previously described species are newly recorded from the Nearctic region; one new name is proposed, 3 species are recombined and 4 specific synonymies are established. — Nearctic Ompahle is divided in 8 species-groups, in addition there are 8 unplaced species. The division of species-groups is partly based on characteristics of male genitalia, a structure very seldom used in taxonomic studies of Eulophidae, but here shown to be a valuable tool in the classification. Seven lectotypes are designated.
