Karyotypes of 34 species referred to 9 genera of 6 tribes and 4 subfamilies of Tenthredinidae are reported. Variation in karyotypes at different taxonomic levels is discussed. The haploid chromosome numbers are shown to range from 6 to 20 in the species studied whereas they range from 5 to 22 in the family as a whole. An ancestral chromosome number for Tenthredinidae is suggested to lie between n=6 and n=10. Some genera are discussed in terms of karyotype diversity. Possible pathways, in which karyotype evolution has proceeded in these genera and in Tenthredinidae as a whole, are discussed.
