Gumovs'kyj O. Chalcidoid wasps of the families Eulophidae and Tetracampidae (Hymenoptera: Chalcidoidea): morpho-biological features and phylogeny.

The analysis of moleсular data demonstrated, that the families Eulophidae, Tetracampidae and Trichogrammatidae are represented by independent clades, that confirms appropriateness of their traditional consideration as separate families, and data of parsimony and maximum likelihood phylogenetic analyses are mainly congruent. It is shown, that the families Eulophidae, Tetracampidae, Trichogrammatidae and Rotoitidae cluster together as a monophyletic complex (Brevicalcarata). The biology of Eulophidae and Tetracampidae is reviewed, new data on parasitoid-host interactions and morphology of immature stages, are obtained. Hypothetic scheme of host shifts and associations of chalcidoid wasps of the Brevicalcarata-complex, is proposed. It is demonstrated that the family Tetracampidae is an arteficial (polyphyletic) group. Some fossil groups classified hithertho as tetracampids are moved to the family Rotoitidae. 7 genera of Eulophidae are described for the first time, the status and structure of 33 genera isrevised, synonymy of 7 generic names is proposed, 11 genera are revised.
