Macrosiphum corallinum Theobald 1925 = Macrosiphum cholodkovskyi (Mordvilko 1909)

The type specimen of Macrosiphum corallinum agreed with samples identified by various European workers as M. cholodkovskyi in a multivariate morphometric analysis by Watson (1982), confirming the opinion of Hille Ris Lambers (1933). Theobald’s aphid was “a most brilliant coral pink”, and M. cholodkovskyi has a form of this colour.
