ABSTRACT. Chromosomes of 13 species of the family Tenthredinidae from the Moscow Province were examined, including those 8 species studied for the first time*: Cladius pectinicornis (Geoffroy, 1785) (n = 6), *Euura clitellata (Serville, 1823) (n = 9), *E. myosotidis (Fabricius, 1804) (n = 8), *Eriocampa dorpatica Konow, 1887 (n = 8, 9), Nesoselandria morio (Fabricius, 1781) (n = 6), Pachyprotasis rapae (Linnaeus, 1767) (n = 10), *Macrophya duodecimpunctata (Linnaeus, 1758) (n = 10), *Sciapteryx consobrina (Klug, 1816) (n = 12), *Empria pumila (Konow, 1896) (n = 13), *Allantus calceatus (Klug, 1818) (n = 9), A. cinctus (Linnaeus, 1758) (n = 9), *Claremontia puncticeps (Konow, 1886) (n = 10) and Eutomostethus luteiventris (Klug, 1816) (n = 10). In a few cases, different chromosome numbers were detected within apparently the same sawfly species. Specifically, n = 6 was previously reported for E. luteiventris from Germany, although identification errors and/or presence of cryptic species cannot be completely ruled out. In almost all embryos derived from both studied females of E. myosotidis n = 8 was found, except for a particular specimen having a similar chromosome set with n = 9 due to the presence of an additional acrocentric. Implications of the detected chromosomal variation for taxonomy and phylogeny of the family Tenthredinidae are discussed.
