The genus drosophila (Diptera) in Eastern Queensland. 1. Taxonomy.

Abstract

Ten species of which six are new, of the genus Drosophila are described and figured: D. cancellata, sp. nov., D. enigma Mall., D. lativittata Mall., D. opaca, sp. nov., D. maculosa, sp. nov., D. levis, sp. nov., D. serrata Mall., D. takahashii Sturt., D. dispar, sp. nov., and D. versicolor, sp. nov. Laboratory cultures of these have been set up from single females fertilized in the wild, allowing descriptions of eggs, larvae, pupae, and certain internal structures and external anatomy of the adults. These species have been assigned to subgenera and species group and their geographical distribution is recorded, together with the known Queensland distribution of D. busckii Coq., D. melanogaster Meig., D. simulans Sturt., D. ananassae Dol., D. hydei Sturt., D. repleta Woll., D. immigrans Sturt., and D. spinofemora Patt. & Wheel. These 18 species are keyed. The taxonomy of the subgenus Pholadoris is discussed, and three new species groups established, namely, coracina, maculosa, and levis. A new species group within the subgenus Sophophora, namely, dispar, is established.
