Allomyrina dichotoma, Linne, 1771

Dutrillaux, Anne-Marie, Mamuris, Zissis & Dutrillaux, Bernard, 2013, Chromosome analyses challenge the taxonomic position of Augosoma centaurus Fabricius, 1775 (Coleoptera: Scarabaeidae: Dynastinae) and the separation of Dynastini and Oryctini, Zoosystema 35 (4), pp. 537-549 : 543

Allomyrina dichotoma : 20,XY ( Fig. 3A )

Published data: Smith & Virkki (1978). The size of the autosomes is less regularly decreasing, which may be due to the amplification of heterochromatin, very abundant and unevenly distributed in centro - meric regions. All are meta/sub-metacentric. The sub-metacentric X is also enlarged by heterochromatin. The Y remains punctiform. NOR location: X chromosome.

FIG. 3. – C-banded karyotype of three representatives of Dynastini: A, Allomyrina dichotoma Linné, 1771; B, Chalcosoma atlas Linnaeus, 1758; C, Augosoma centaurus Fabricius, 1775. Notice that most chromosomes of A. centaurus are acrocentric (entirely heterochromatic [dark] short arms) as in O. rhinoceros Linnaeus,1758 (Fig.2) and O.nasicornis Linnaeus,1758 (Dutrillaux & Dutrillaux, 2012). Scale bars: 10 µm.
