oa Annals of the Natal Museum - A new genus of the Xestomyza-group from the western coast of South Africa, based on two new species with flightless females (Diptera: Therevidae)

Volume 21, Issue 3
  • ISSN : 0304-0798



Lyneborgia gen. nov. and its included species, ammodyta sp. nov. and stenoptera sp. nov., are diagnosed with respect to egg, first and last instar larva, pupa, and adult. Adults of both species are descriptionbed. Certain features of the genus are discussed: flightlessness, phallus asymmetry, oviposition, and hatching sequence. Larval cephalic terminology is revised. The relationships of Lyneborgia to the other genera of the Xestomyza-­group, and especially Henicomyia Coq. of the New World, are discussed. A sister-group relationship between Lyneborgia and Henicomyia is postulated.
