Abstract

A fairyfly (Hymenoptera, Mymaridae) Cleruchus breviclava Triapitsyn & Coray, sp. nov. is described and illustrated. The new species is an egg parasitoid of the invasive Cis chinensis Lawrence (Coleoptera, Ciidae) in Antrodia xantha fungus (Polyporales, Fomitopsidaceae) in Basel, Switzerland; it is also known from low mountains in Germany and Switzerland. Supporting data on the “barcoding” region of the mitochondrial cytochrome c oxidase subunit I gene, as well as separate regions of nuclear ribosomal RNA, the D2 region of 28S and the internal transcribed spacer 2, provide strong evidence of conspecificity of the morphologically variable macropterous and strongly brachypterous individuals of C. breviclava. Macropterous females of the new species are most similar to those of C. detritus Bakkendorf, also known from Switzerland. New records are provided for some other species of Cleruchus Enock in Europe. A key to both sexes of the described European species of the genus is given.
