Abstract
A new species of the genus Metopolophium Mordvilko, 1914 (Hemiptera: Aphididae: Aphidinae: Macrosiphini) is described and illustrated. Apterous and alate viviparous females, oviparous females, and apterous males of Metopolophium rogeri sp. nov. on Rosa beggeriana (Rosaceae) are collected from Kerman Province, Iran. The new species is morphologically most similar to M. alpinum Hille Ris Lambers, 1966, but is characterized by the low ratio of processus terminalis to basal segment of antennal segment VI, high ratio of siphunculus to cauda length and the presence of many more accessory setae on the ultimate rostral segment. This holocyclic aphid is monoecious and not attended by ants. The biometric data are given, and the key to the aphids associated with Rosa species in Blackman and Eastop (2021) is modified to accommodate the new species.
