Occurrence of European Rhinoceros Beetle, iOryctes nasicornis/i(L.) (Coleoptera: Scarabaeidae), in the Southern Highlands of Tanzania

摘要

The European rhinoceros beetle, Oryctes nasicornis (L.), is a large flying beetle in the subfamily Dynastinae of family Scarabaeidae and order Coleoptera. It is well-known to be a Palaearctic species, inhabiting Europe and Asia up to North Africa, with no reported material from the Sub-Saharan African region including Tanzania. The present work reports an occurrence of O. nasicornis in Tanzania specifically in Iringa region in the Southern Highlands zone of the country. The report is accompanied by description of the key morphological characters of the insect validating its diagnosis. The findings facilitate a basis for intervention of the existing records about O. nasicornis, including its biogeographical affiliation and the related undertakings. It is most likely that the species also ranges in other localities in Tanzania and the Sub-Saharan Africa region in general because of the existing proximity and interactions.
