Males in several species (mainly in the tribes Dynastini, Agaocephalini, and Oryctini) possess prominent horns on the head and/or the thorax, which, because of their great size, give rise to vernacular names such as "rhinoceros beetle", "elephant beetle", "Hercules beetle" or "unicorn beetle" (Ratcliff ...
Taxonomic distribution of tympanal organs within the dynastine Scarabaeidae SUBFAMILY Tribe Genus Tympanic membranes DYNASTINAE Cyclocephalini Cyclocephala Yes Dyscinetus Yes Pentodontini Euetheola Yes Oxygrylius Yes Bothynus No Aphonus No Dynastini Dynastes No Phileurini Phileurus No Oryctoderini?
These structures have been previously neglected as taxonomic characters in the Dynastini, but here provide the principal basis for establishing both the terminal taxa for the phylogenetic analysis and a new, readily testable taxonomic system for Xylotrupes .
Very large species, over 50 mm in length; male glabrous; with long, head and pronotal horns, one above the other; female without horns, closely roughly punctate, pronotum densely covered with short brownish hair (Dynastini) Dynastes Hercules Hercules (Linnaeus) Species less than 50 mm in length; other ...
