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

Dyscinetus picipes : 20,XY ( Fig. 2D )

Published data: none. Pairs 1,3,5,7 and 9 are almost metacentric and pairs 2, 4, 6 and 8 are sub-metacentric, The X is sub-metacentric and the Y is punctiform. NOR location: X chromosome.

Figures

FIG. 2. – C-banded karyotypes of representatives of four Dynastinae tribes: A, Pentodon idiota Herbst, 1789 (Pentodontini); B, Phileurus valgus antillarum Prell, 1912 (Phileurini); C, Oryctes rhinoceros Linnaeus, 1758 (Oryctini), in this karyotype, heterochromatin is very abundant, forming short arms of acrocentrics (dark portions on nos 3-7) and intercalated in euchromatin (small dark bands in all autosomes), heterochromatin is much less abundant in O. nasicornis Linnaeus, 1758; D, Discinetus picipes Burmeister, 1847 (Cyclocephalini).
