Parydra I imagine(?) following comparison with gallery images.
If so, appears to key to P.quadrifasciatus in Drake 2006.
- Yellow dusting on face.
- No prominent tubercle on scutellum.
- Appendix to wing vein.
- Wing markings indistinct
- Fan on front femora seems pale and about same length as narrowest width of femur itself.
- Silver markings at base of mid-tibia
Definitely on the larger side - perhaps 4mm or so?
About twice the size of the other small Ephydrids I photographed there.

no prominent tubercle on scutellum I believe, ruling out P.coarctata
this image from one of the other flies, but the same business
