Ultrastructural analysis of species of Turkish Dioctriinae (Diptera, Asilidae)

In the present study, body and egg morphologies of 16 taxa belong to Dioctria genus (D. abdominalis, D. arcana, D. atricapilla, D. cornuta, D. engeli, D. flavipennis, D. hermonensis, D. linearis, D. meyeri, D. sudetica, D. valida, Dioctria sp.1, Dioctria sp.2, Dioctria sp.3, Dioctria sp.4 ve Dioctria sp.5) and 1 species belong to Molobratia genus were studied with Scanning Electron Microscopy and genitalia morphologies were studied with light microscopy. All examined eggs of Dioctria taxa are ovoid in shape and brown colored. Egg morphology separates species from each other. Egg surface of some species are covered with crown or cup shaped oval rings and the others have are polygonal and perforated egg surface. There are significant differences in mystax, frons and mouth protuberance, length of antennal segments, shape of proboscis, tomentum of face, tomentum of pleurae, basitarsus segment of hind leg and thickening of apical part of tibia of examined species.
