Abstract [en]

A key is presented to the European genera of Eucoilinae, for the first time after these genera have been circumscribed based on type studies and phylogenetic concerns. The key is illustrated with drawings based on SEM pictures. A generic catalogue with full synonymy of the European eucoiline genera is presented. The following new synonymies on the generic level are proposed: Trichoplasta Benoit, 1956 (Armigerina Belizin, 1968 syn.n.), Eucoila Westwood,1833 (Lenobria Belizin, 1968 syn.n.), Kleidotoma Westwood, 1833 (Nesokleidotoma Beardsley, 1990 syn.n., Octameris Belizin, 1973 syn.n., Polbourdouxia Dessart, 1977 syn.n., Pentakleidota Weld, 1951 syn.n.). One species level synonymy is proposed: Eucoila floralis Dahlbom, 1846 (Lenobria bidentata Belizin, 1968 syn.n.) A tribal classification of the subfamily is utilised, recognizing the following tribes: Diglyphosemini Belizin, 1961 stat.n.,Kleidotomini Hellén, 1960 stat.n. (Cothonaspini Belizin, 1961 syn.n.), Ganaspini Belizin,1961 stat.n. (Dieucoilini Belizin, 1961 syn.n., Glauraspidiini Belizin, 1961 syn.n.),Trichoplastini Kovalev, 1989 and Eucoilini Thomson, 1862.

Abstract [en]

Many animal species are still undiscovered, even in Sweden. This thesis deals with the wasps of the subfamily Eucoilinae (of Figitidae, Cynipoidea), a poorly known group of small parasitoids of Dipteran flies. In this group, old classifications are chaotic, knowledge of old taxa is scant, phylogenetic work has recently started, and many new taxa remain to be described.

In this thesis, an identification key is given to the European genera of Eucolinae, and a tribal classification of the subfamily is reintroduced, based on recent phylogenetic results. Most of the thesis focuses on the tribe Eucoilini. That tribe is analyzed phylogenetically in two analyses, one based on a large morphological dataset, the other on two molecular markers, ribosomal 28S and mitochondrial Cytochrome B.

The monophyletic core group of Eucoilini is the Eucoila/Trybliographa complex. It is treated in a big taxonomic revision, based on studies of several hundred possibly relevant type specimens and several thousands of other specimens, and on the phylogenetic analyses.

More than 500 names of possible members of this group are investigated, and many new combinations are proposed, of species found not to belong within the group, as well as those that did, including some which are transferred to other genera in accordance with the new phylogenetic results. The new genus Quasimodoana is erected, and 20 new species described (8 from Northern Europe, 12 from elsewhere). More than 180 new combinations, more than 50 new species-level synonyms and ca 10 genus-level synonyms, are proposed.

Within this complex, the basal split is found to have been between a Paleotropic, specis-poor lineage (Bothrochacis), and a species-rich and largely Holarctic lineage, dominated by Trybliographa but also including the small genera Eucoila and Linoeucoila. The three are not satisfactorily resolved in the analysis, but still maintained as separate genera for pragmatic reasons. It is hypothesized that this group originated in Asia during the Eocene or Oligocene, attacking calyptrate flies in herbivore dung. Then it separated in a tropical branch retaining the ancestral life history mode, and a Holarctic branch, where some lineages specialised in Anthomyiidae and colonised the microhabitats of fungi and plants, speciating extensively in the boreal forests.
