Aphis pulsatillae Ossiannilsson 1959 = Aphis montanicola Hille Ris Lambers 1950

In the original description of montanicola, the last rostral segment is erroneously described as shorter than the second segment of the hind tarsus, leading to pulsatillae being described and recognised as a separate species. Comparison of type material of montanicola and pulsatillae in the BMNH collection failed to reveal any substantive differences.
