Apterous and alate viviparous females and the alate males of Macrosiphum eastopi Barjadze & Blackman sp. n. living on Oberna multifida Ikonn. (=Silene multifida Rohrb.) (Caryophyllaceae) are described from the Republic of Georgia (Caucasus). Type specimens are deposited at the Institute of Zoology, Ilia State University (IZISU), Tbilisi, Georgia; the Natural History Museum (BMNH), London, U.K.; and the University of Catania (UCI), Sicily, Italy. Apterous and alate viviparous females of its close relative M. hartigi Hille Ris Lambers, 1947, living on Silene vulgaris (Moench) Garcke and Stellaria holostea L. (Caryophyllaceae) are redescribed, based on co-types and other material from Austria, France, Italy and Switzerland. The hitherto unknown fundatrix, oviparous females and alate males of M. hartigi are described from Italy and Switzerland. Macrosiphum eastopi sp. n. is differentiated from the morphologically similar M. hartigi and compared with other Macrosiphum species living on Caryophyllaceae. A key is provided to apterous viviparous females of all aphid species recorded on Oberna multifida.
描述了寄生于多裂奥贝纳草（=多裂蝇子草）（石竹科）上的东氏长管蚜新种Macrosiphum eastopi Barjadze & Blackman的无翅和有翅胎生雌蚜以及有翅雄蚜，该草分布于格鲁吉亚共和国（高加索地区）。模式标本保存于格鲁吉亚第比利斯伊利亚国立大学动物研究所（IZISU）、英国伦敦自然历史博物馆（BMNH）以及意大利西西里卡塔尼亚大学（UCI）。基于来自奥地利、法国、意大利和瑞士的同型标本及其他材料，重新描述了其近缘种哈氏长管蚜Macrosiphum hartigi Hille Ris Lambers, 1947的无翅和有翅胎生雌蚜，该蚜虫寄生于普通蝇子草（Moench）Garcke和全缘繁缕Stellaria holostea L.（石竹科）上。描述了来自意大利和瑞士的此前未知的哈氏长管蚜干母、卵生雌蚜和有翅雄蚜。将东氏长管蚜新种与形态相似的哈氏长管蚜进行了区分，并与寄生于石竹科植物上的其他长管蚜物种进行了比较。提供了一个鉴别寄生于多裂奥贝纳草上所有蚜虫物种无翅胎生雌蚜的检索表。
