Amphimallon majale : 20,XY ( Fig. 1 B )

Published data: Dutrillaux & Dutrillaux (2012). The size of autosomes is progressively decreasing. They are all meta- or sub-metacentric. Compared to A. flavipennis , the centromeres of pairs 4 and 6 are fairly distal and that of pair 1 is more median. C-bands are larger. The X is a small sub-metacentric and the Y is punctiform, but heavily C-banded.
