NEW SPECIES OF THE GENUS KLIMASZEWSKIA SZELEGIEWICZ 1979 (HOMOPTERA, APHIDIDAE) FROM KAZAKHSTAN

摘要

Two new species of the genus Klimaszewskia were described among the aphids collected in 2010-2011 at the "Katonkaragaiskii" State National Natural Park (the Kazakhstan part of the Altai Mountains). Klimaszewskia altaica Kadyrbekov sp. n. inhabiting on Nepeta sibirica and K. katonica Kadyrbekov sp. n. living on Dracocephalum grandiflorum differ from the other known species of this genus by a smaller number of hairs on the ultimate rostral segment and the second segment of hind tarsus and also by the presence of unclearly expressed, strongly flattened marginal protuberances. They differ among themselves by the ratio of processus terminalis to the base of the sixth antennal segment (3.6-4.6 and 4.2-5.2 in the first and the second), of siphunculi to the body length (0.17-0.24 versus 0.25-0.27), of cauda to the second segment of hind tarsus (1.7-2.2 and 2.25-2.35), as well as by the length of hairs on frontal furrows, antennae and tergites, the number of hairs on the eighth tergite (8-10 and 2-3), and by the number of secondary rhinaria on the third antennal segment (3-12 compared to 0-2). Holotypes and some paratypes of the new species are deposited in the collection of the Institute of Zoology (Almaty, Kazakhstan). Some part of the paratypes are kept at the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia).
