Another two new aphid species of the genus Cryptomyzus Oestlund, 1922 (Hemiptera, Aphididae, Macrosiphini) from Kazakhstan

Two new species of the genus <i>Cryptomyzus</i> living on Lamiaceae are described from specimens preserved in the collection of the Institute of Zoology of the Republic of Kazakhstan (Almaty). Cryptomyzus (Cryptomyzus) saryarkensis<b>sp. nov</b>. living on the ground parts of <i>Phlomoides tuberosa</i> in Saryarka region of the Kazakh Uplands in North Kazakhstan and C. (C.) nepetaphilus<b>sp. nov</b>. living on the ground parts of <i>Nepeta cataria</i> in Zhongar Alatau mountain system in south-eastern Kazakhstan. All measurements were taken on a Bel Photonics BIO 3T light microscope. <i>Cryptomyzus</i> (<i>C.</i>) saryarkensis<b>sp. nov</b>. is closest to C. (C.) maudamanti Guldemond, 1990 and C. (C.) galeopsidis (Kaltenbach, 1843). <i>Cryptomyzus</i> (<i>C.</i>) nepetaphilus<b>sp. nov</b>. is related to C. (C.) ribis (Linnaeus, 1758). Identification keys to related species of <i>Cryptomyzus</i> are provided. Two centres of species diversity of the genus <i>Cryptomyzus</i> are clearly visible in Europe (6 species) and Central Asia (9). <i>Cryptomyzus</i> (<i>C.</i>) ribis (Linnaeus, 1758), C. (C.) korschelti Bӧrner, 1938, C. (C.) alboapicalis (Theobald, 1916), and C. (C.) galeopsidis (Kaltenbach, 1843) are distributed much more widely. <i>Cryptomyzus</i> (<i>C.</i>) taoi Hille Ris Lambers, 1963 is known from Pakistan, India, Russian Far East, and Japan, and C. (C.) behboudii Remaudière & Davatchi, 1961 is known from Turkey and Iran.
