Lauxaniidae is a family of acalyptrate flies with around 1500 described species in 126 genera distributed worldwide. Some, like this Cephaloconus tenebrosus are unusually shaped and appear to mimic other insects, possibly leafhoppers in this case.

Lauxaniid flies have wings that are wings often clear, but some groups, such as Homoneura, have patterned wings. The folks at diptera.info have made a positive ID of this fly as being a Homoneura sp.

Also Homoneura. They are really diverse in this neck of the woods! (Australia and Southeast Asia). (Steve Gaimari, Diptera.info)

A Lauxaniid fly of the genus Sapromyza about 3mm in body length hovering around a Syzygium in my garden in Brisbane while I was experimenting with a Pansonic Lumix with Raynox magnifier. It landed on my hand so I was able to manoeuvre it into the sun for this pic. Thanks Steve Gaimari for ID, who notes: "important characteristics - the paired blackish patches on the occiput, the legs and antennae being dark, unmarked wings, 0+3 dc with anterior seta smallest..." Sapromyza occipitalis Malloch

Steve Gaimari wrote: Again "Sapromyza", but this time, it is Sapromyza sciomyzina Schiner. Nice pics! Notice the entirely black frons (in the other - Sapromyza occipitalis - the frons were yellow), the parafacial is silver and the face is black, the thorax is more uniformly orange, the forelegs very dark, the mid and hind femora lighter, etc.
