Karyological studies were carried out on three Armenian weevil species from the subfamily Cleoninae. The following chromosome numbers were found in individual species: 2n = 38, n% = 18+Xyp in Menecleonus anxius (Gyllenhal, 1824), 2n=40, n% = 19+Xyp in Conorhynchus nigrivittis (Pallas, 1781) and 2n = 44, n% =21+Xyp in Lixus iridis Olivier, 1807. The heterochromosomes of all the examined species form, in the first meiotic metaphase, a typical parachute bivalent.
