A key to Australian species of Drosophila with seriate spinescent setulae on fore-femur 
Seven Drosophila species that occur in temperate and tropical forests of eastern and northeastern Australia 
and New Guinea could be confused with Drosophila setifemur because, except for males of D. setifemur, 
they all have seriate spinescent setulae anteroventrally on the fore-femur—the following key allows them 
to be correctly identified. 
1 Vibrissa single. Drosophila teratos 
-Vibrissa double . 2 
2 Males. 3 
-Females . 8 
3 Fore femur distinctly swollen (often collapsed and flattened in 
pinned specimens), densely hirsute ventrally along its entire 
length, and without distinctive series of spinescent setulae in 
apical, anteroventral, half (Fig. 3); terminalia characterized by a 
pair of long, slender, semi-translucent, appendages usually visible 
without dissection . 4 
-Fore femur not distinctly swollen, rarely collapsed in pinned 
specimens, diameter of fore-, mid-, and hind-femora subequal, 
ventral surface with a few scattered hairs near base only, with 
distinctive series of short spines in apical, antero ventral, half 
(Figs. 8, 11-13); many setae on posteroventral surface of fore¬ 
femur longer than femoral diameter; terminalia without slender 
appendages as described above. 5 
4 Appendages of terminalia tapering to a point apically and strongly 
curved, Eastern Australia. Drosophila setifemur 
-Appendages of terminalia blunt apically and not strongly curved, 
western Victoria. Drosophila prodispar 
5 Thorax and abdomen blackened ventrally; weakly developed seriate 
spinescent setulae on fore-femur . Drosophila rubida Mather, 1960 
-Thorax and abdomen not blackened ventrally; strongly developed 
seriate spinescent setulae on fore-femur. 6 
6 Abdominal tergites with broad apical black bands dorsally only, 
fringe of heavy setation in about 0.3-0.4 of third costal section 
(common at fruit baits and compost in cool temperate Australia, 
peridomestic worldwide distribution), front without distinctive 
silvery pruinescence. Drosophila immigrans
