oa Annals of the Natal Museum - Morphology of the terminalia and known ovipositing behaviour of female Therevidae (Diptera: Asiloidea), with an account of correlated adaptations and comments on phylogenetic relationships

Volume 22, Issue 3
  • ISSN : 0304-0798



The ovipositing behaviour and morphology of the female terminalia of species within several suprageneric taxa of the family Therevidae are descriptionbed. The mode of oviposition and oviposition substrate are not easily deduced from a study of the morphology of the female terminalia. A descriptionp­tive model relating form (morphology) and function (oviposition) is generated. A phylogenetic assessment of the genus-groups of Therevidae is presented, based on the morphology of the female terminalia and ovipositing behaviour. The Apsilocephala group does not easily fit into the concept of the family Therevidae, and, if it is to be retained within the family, it logically has a sister-group relationship to the rest of the Therevidae.
