Taxonomic studies on some little known genera of Palearctic Eulophidae and Pteromalidae (Hymenoptera: Chalcidoidea)

چکیده
Some neglected genera of Palearctic Eulophidae and Pteromalidae (Chalcidoidea) are reviewed as part of ongoing preparation of keys to identification of world genera of these families. Some of these genera are represented by distinctive species which properly belong to larger genera, and some were described based on misinterpreted morphological characters. Bryopezus Erdös syn. nov. is synonymized under Deutereulophus Schulz, Danuviella Erdös syn. nov. under Diglyphus Walker, Cleolophus Mercet syn. nov. and Parpholema Szelényi syn. nov. under Hemiptarsenus Westwood, Dubiostalon Szelényi syn. nov. under Neotrichoporoides Girault, and Dudichilla Szelényi syn. nov. under Syntomopus Walker. Deutereulophus brevipennis (Erdös) comb. nov., Diglyphus subplanus (Erdös) comb. nov., Hemiptarsenus autonomus (Mercet) comb. nov., Hemiptarsenus virescens (Storozheva) comb. nov., Neotrichoporoides inusitatus (Szelényi) comb. nov., Mesopolobus fuscus (Szelényi) comb. nov., Syntomopus crassicornis (Szelényi) comb. nov. are new combinations resulting from these changes. Two species are transferred to their proper genera: the brachypterous species Necremnus collaris (Szelényi) comb. nov. from Microlycus Thomson, and Mesopolobus fuscus (Szelényi) comb. nov. from Tricolas Bouček. Neanica Erdös is discussed as a distinct and valid genus within Pteromalinae, with comparison to other genera. The replacement name Hemiptarsenus collapsus nom. nov. is chosen for Parpholema collaris Szelényi, which becomes a junior homonym of Hemiptarsenus collaris (Ashmead). Reasons for taxonomic changes are discussed with reference to distinctive features shared with species in other genera. One newly discovered morphological feature is discussed, the prepectal bulge found in some Sphegigastrini (Pteromalidae). Photographs of type specimens are provided to facilitate future recognition of these species.

Chalcidoidea (Hymenoptera) are extremely diverse with more than 23,000 species described and over 500,000 species estimated to exist. This is the first comprehensive phylogenetic analysis of the superfamily based on a molecular analysis of 18S and 28S ribosomal gene regions for 19 families, 72 subfamilies, 343 genera and 649 species. The 56 outgroups are comprised of Ceraphronoidea and most pro...

Ratzeburgiola Erdös is a small but phylogenetically interesting genus exhibiting a combination of characters once used to define both the former tribes Elachertini and Eulophini of the subfamily Eulophinae (Hymenoptera: Chalcidoidea: Eulophidae). It was once classified in the tribe Elachertini with genera having scutellar grooves and complete notauli, but in some characters it resembles the gen...

Based on recently collected Pteromalidae (Hymenoptera: Chalcidoidea), 13 species were identified from genera of Pteromalinae that are characterized in part by the female clava being distinctly acuminate or apically bearing a narrow spicula. Included are two species of Callitula Spinola, three species of Homoporus Thomson, seven species of Norbanus Walker, and one species of Rhaphitelus Walker. ...
