Combined molecular and morphological phylogeny of Eulophidae (Hymenoptera: Chalcidoidea), with focus on the subfamily Entedoninae.

A new combined molecular and morphological phylogeny of the Eulophidae is presented with special reference to the subfamily Entedoninae. We examined 28S D2-D5 and CO1 gene regions with parsimony and partitioned Bayesian analyses, and examined the impact of a small set of historically recognized morphological characters on combined analyses. Eulophidae was strongly supported as monophyletic only after exclusion of the enigmatic genus Trisecodes. The subfamilies Eulophinae, Entiinae (=Euderinae) and Tetrastichinae were consistently supported as monophyletic, but Entedoninae was monophyletic only in combined analyses. Six contiguous bases in the 3e' subregion of the 28S D2 rDNA contributed to placement of nominal subgenus of Closterocerus outside Entedoninae. In all cases, Euderomphalini was excluded from Entiinae, and we suggest that it be retained in Entedoninae. Opheliminae n. stat. is raised from tribe to subfamily status. Trisecodes is removed from Entedoninae but retained as incertae sedis in Eulophidae until its family placement can be determined new placement. The genera Neochrysocharisstat. rev. and Asecodesstat. rev. are removed from synonymy with Closterocerus because strong molecular differences corroborate their morphological differences. Closterocerus (Achrysocharis) germanicus is transferred to the genus Chrysonotomyian. comb. based on molecular and morphological characters.
