Acyrthosiphon bidentis Eastop 1953


Acyrthosiphon bidentis Eastop 1953   = Acyrthosiphon ilka Mordvilko 1914   (valid name)

African populations identified as A. bidentis   tend to have longer, more slender SIPH than Eurasian populations of A. ilka   , but have almost identical host plant preferences across several families ( Papaveraceae, Compositae, Cruciferae   , Linaceae   ), so that A. bidentis   is best considered as a geographical variant of A. ilka   . Remaudière and Remaudière (1997) questioned the validity of Mordvilko’s species but the 1914 description is detailed and seems unambiguous.
