Flies in the family Dolichopodidae are small, and usually brightly metallic with long legs. They are all called 'Long-legged Flies'. The subfamily Sciapodinae is distinguished based on the head shape (the bulging eyes and concave regions between give the head a dumb-bell like appearance) and the wing venation (M vein extends to the wing margin).
There are many genera, and the distinction between them often relies upon microscopic features not easily recognised in a photograph. However, Austrosciapus is a genus that is well-represented in our Atlas of Life region (according to Museum records and an authoritative paper by Bickel, 1994) and favours dry sclerophyll forest.
