Several new and one invasive aphid species (Aphididae, Hemiptera) caught by yellow water traps in Serbia

Eight aphid species were determined as new records for Serbia as a result of the evaluation of the specimens caught by yellow water traps used for monitoring vector activities in seed potato crops during the 4 years 2007-2010. The invasive aphid species Macrosiphum albifrons Essig 1911; and the new species Acyrthosiphon cyparissiae (Koch 1855), Ctenocallis setosus (Kaltenbach 1846), Myzodium modestum (Hottes 1926), Myzocallis castanicola Baker 1917, Myzocallis occidentalis Remaudie et Nieto Nafria 1974, Tinocallis platani (Kaltenbach 1843) and Wahlgreniella ossiannilssoni Hille Ris Lambers 1949. M. modestum is very difficult to detect, as it lives hidden in moss. All species are presented with characteristic morphological information of alatae and line drawings
