Chromosomes of ichneumonids of the subfamily Pimplinae, Dolichomitus terebrans (Ratzeburg) (2n = 34), Scambus nigricans (Thomson) (2n = 28), Pimpla turionellae (Linnaeus) (2n = 30) and Perithous scurra (Panzer) (= mediator (Fabricius)) (2n = 42) were studied for the first time. Chromosome numbers of the examined species of Pimplinae are comparatively high (2n = 28 or more, with the single exception of 2n= 18), and that of P. scurra is the highest in all parasitic wasps.

New data on the karyotype structure of five species of the subfamily Eurytominae are escribed, including the following species: Eurytoma rosae (2n=20), E. robusta (n=7, 2n=14), E. serratulae (n=6, 2n=12), E. compressa (2n=10) and Sycophila biguttata (2n=18). 2n=10, 12 and 14 are reported for the first time for the Eurytominae, in which only 2n=20 and 18 have been previously found. The taxonomic and phylogenetic implications of the new chromo- somal information are discussed. Karyotypes containing ten subtelo/acrocentric chromosomes which gradually decrease in size can be considered as initial for the Eurytominae. Eurytoma robusta + (E. serratulae + E. compressa) form a particular clade where all branches are well-supported by morphological, biological and chromosomal a
