oa Journal of the Entomological Society of Southern Africa - The anatomy, histology and physiology of the internal adult male reproductive system of Parastizopus armaticeps Peringuey (Coleoptera: Tenebrionidae)

Volume 45, Issue 2
  • ISSN : 0013-8789



The reproductive system consists of the testes, vasa efferentia and deferentia, vesiculae seminales, three pairs of accessory glands (bean-shaped, tubular, and ectadenia), the ductus ejaculatorius and the aedeagus, all of which are descriptionbed and illustrated. As well as large volumes of viable spermatozoa, the testes produce spermatogonia, which provides histological confirmation of the long adult life of Parastizopus annalieeps. During copulation the beetle produces a spermatophore, in the formation of which the bean-shaped accessory glands play a cardinal role.
