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 Male = 18 + Xyp in Menecleonus anxius (Gyllenhal, 1824), 2n = 40, n Male = 19 + Xyp in Conorhynchus nigrivittis (Pallas, 1781) and 2n = 44, n Male = 21 + Xyp in Lixus iridis Olivier, 1807. The heterochromosomes of all the examined species form, in the first meiotic metaphase, a typical parachute bivalent.
对来自Cleoninae亚科的三种亚美尼亚象鼻虫进行了核型研究。在各个物种中发现了以下染色体数目：Menecleonus anxius（Gyllenhal，1824）中2n = 38，雄性n = 18 + Xyp；Conorhynchus nigrivittis（Pallas，1781）中2n = 40，雄性n = 19 + Xyp；Lixus iridis Olivier，1807中2n = 44，雄性n = 21 + Xyp。在第一次减数分裂中期，所有被检查物种的异染色体形成典型的降落伞二价体。
