New species of Nanexila Winterton & Irwin and Taenogera Kröber from Australia (Diptera: Therevidae)

Abstract

Two new species are described in each of the closely related genera Nanexila Winterton & Irwin and Taenogera Kröber. Nanexila atricauda sp. nov. and Nanexila jimrodmani sp. nov. are described. The phylogenetic placement and diagnostic characteristics of these new species and other species recently transferred to Nanexila are discussed. Taenogera luteola sp. nov. and Taenogera brunnea sp. nov. are distinctive species described from female specimens collected in Queensland. Taenogera is diagnosed in light of these new species and a revised key to species presented. Copyright © 2007 Magnolia Press.
