Remarks . Uroleucon ( Uroleucon ) altaicum Szelegiewicz, 1962 was synonymized with U. mulgedii only based on description of U. altaicum and redescription of U. mulgedii without examination of type material of U. altaicum ( Holman 1991 ; Eastop & Blackman 2005 ). Morphological differences between the type specimens of U. altaicum from Mongolia and specimens of U. mulgedii from Uzbekistan and Bulgaria (mostly ratios involving URS and siphunculi; see Discussion) should be treated as differences between two separate species. Taking this into account, we propose to restore the full species status of U. altaicum . On the basis of the pigmentation of siphunculi (pigmented with pale bases), pale coxae and cauda, poorly developed and pale sclerites and scleroites on the abdomen, we propose to transfer this species from the subgenus Uroleucon to subgenus Lambersius .
