Molecular phylogeny of the Eucoila/Trybliographa complex (Hymenoptera: Cynipoidea: Figitidae)
(English)Manuscript (preprint) (Other academic)
The Eucoilinae are small parasitic wasps attacking larvae of Diptera. Some species are important biological control agents; others are popular model organisms. One of the most species-rich groups in the Holarctic is the Eucoila/Trybliographa complex, which has previously been in a state of major classificatory disorder. One of the reasons for this has been the lack of knowledge of phylogenetic relationships. To address this, we have made a molecular phylo-genetic analysis of 51 taxa, comprising a representative sample of taxa of the complex, based on 28S nuclear ribosomal and CytB mitochondrial sequences. The analysis clearly shows the Eucoila/Trybliographa complex to be a monophyletic group. Within this group, there is a basal division between a Paleotropic, species-poor branch, identified as the genus Bothrochacis, and a species-rich, largely Holarctic branch comprising the remainder of the complex. A basal lineage within the latter corresponds to the genus Eucoila, and another to the small genus Linoeucoila from Taiwan. However, their exact relationships to each other and to basal lineages of the big genus Trybliographa, which comprises the remainder of the clade, remains uncertain. Within Trybliographa, several interesting relationships are suggested, but the result is not robust or comprehensive enough at this point for a major reclassification of the genus.
