Revision of the genus Apterodromia (Diptera: Empidoidea), with a redefinition of the tribe Ocydromiini
Abstract
The Australian endemic genus Apterodromia Oldroyd (Diptera: Empidoidea) is revised and includes four apterous species (A. evansi Oldroyd, A. minuta n.sp, A. setosa n.sp., and A. tasmanica n.sp.) and eight fully winged species (A. aurea n.sp., A. bickeli n.sp., A. irrorata n.sp., A. monticola n.sp., A. pala n.sp., A. spilota n.sp., A. tonnoiri n.sp., and A. vespertina n.sp.). The male of A. evansi is described and zoogeographic patterns of the genus are discussed. On the basis of wing venation and male terminalia Apterodromia is transferred from the Tachydromiinae to the tribe Ocydromiini (subfamily Ocydromiinae). The Ocydromiini is redefined, two new genera (Neotrichina n.gen. and Leptodromia n.gen.) are described, and all included genera are listed. Keys to major lineages of Australian Empidoidea and Southern Hemisphere genera of Ocydromiini are provided. The following new combinations are listed: Hoplopeza tachydromiaeformis (Bezzi), Leptodromia bimaculata (Bezzi), Neotrichina abdominalis (Collin), N. digna (Collin), N. digressa (Collin), N. distincta (Collin), N. elegans (Bigot), N. fida (Collin), N. indiga (Collin), N. insignis (Collin), N. insons (Collin), N. laeta (Collin), N. media (Collin), and N. obscurata (Collin).
