BIOTAXONOMY OF TEPHRITOIDEA Isr. J. Entomol. Vol. 35-36, 2005/6, pp. 163-196 Catalog and Revised Classification of the Gastrozonini (Diptera: Tephritidae: Dacinae) Damir Kovac,1 Patrick Dohm,1 Amnon Freidberg2 and Allen L. Norrbom3 ABSTRACT A catalog of Gastrozonini is presented based on the recent world catalog of Tephritidae and subsequent taxonomic and nomenclatural changes. The Gastrozonini are defined taxonomically and biologically, primarily as the Poaceae-infesting Tephritidae other than Acanthonevrini. Although morphological synapomorphies are scant, the group is probably a monophyletic unit based primarily on host plant records and a few other potential synapomorphies such as characters of the antenna, wing and terminalia. Larvae of the gastrozonine species that we studied have a ridge on the ventral tubercle of the caudal segment, confirming the relationship of Gastrozonini with Dacini and Ceratitidini. A key to all included genera of Gastrozonini is provided, and new taxonomic and nomenclatural changes introduced in the catalog are explained. The current classification comprises 27 1Forschungsinstitut Senckenberg, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany. E-mail (Kovac):

The remaining group of genera extends from the southeastern part of the Palaearctic Region through the entire Oriental Region into the Australasian Region, as far south as Australia, but is predominantly Oriental.
