What is Confirmation that Myzus antirrhinii (Macchiati) (Hemiptera: Aphididae) occurs in Australia, using morphometrics, microsatellite typing and analysis of novel karyotypes by fluorescence in situ hybridisation about?

## Abstract Aphids ascribable to __Myzus antirrhinii__ (Macchiati) are shown to be widely distributed in Australia. This species is a member of the __Myzus persicae__ group and confusion with the green peach aphid, __M__. __persicae__ (Sulzer), is likely. We describe here investigations of some Australian clones of __M. antirrhinii__ and extend the definition of the species to include observations on Australian specimens. We conclude that there is a cluster of Australian clones conforming morphometrically to __M. antirrhinii__ when all characters are used. These clones include 11‐ and 12‐chromosome karyotypes that are not found in European or North American populations of __M. antirrhinii.__ The novel chromosome rearrangements were investigated using fluorescence __in situ__ hybridisation and were shown to be derivable from the typical 13‐chromosome karyotype of this species. Microsatellite analysis corroborates the distinction of __M. antirrhinii__ from __M. persicae__. A microsatellite test for separating __antirrhinii__ from __persicae__ is suggested.
