| Abstract: | The aphid genus Blackmania gen. nov. is described. In the genus, B. eastopi sp. nov. associated with Polygonum equisetiforme (Polygonaceae) from Israel and Cyprus is described and illustrated. Morphologically, the new genus is similar to the genus Acaudella in respect to the lack of a cauda. Acaudella puchovi, associated with Atraphaxis caucasica (=A. buxifolia) and A. spinosa (Polygonaceae) from Uzbekistan and Israel, is re‐described and the apterous viviparous female is figured for the first time. The lectotype and paralectotypes of A. puchovi are also designated. An identification key to known species of the tribe Macrosiphini without cauda is provided. The morphological separation of B. eastopi gen. nov., sp. nov. from A. puchovi is visualized using principal component analysis. |
