Propomacrus bimucronatus : 20,XY ( Fig. 1D )

Published data: Dutrillaux & Dutrillaux (2012). The size of autosomes is progressively decreasing, all but pair no. 9 are meta-/sub-metacentric and pair no. 9 is almost acrocentric. The X is enlarged by a large C-band, while the Y remained punctiform. There are some small intercalary C-bands on larger autosomes. NOR location: chromosome 9.
