Caught in Malaise trap 13-20 July 2019. I initially sorted this to Nematocera, but I'm no longer certain - appears to have two delicate wings, not sure about halteres, reduced mouthparts (two discs lined by bright coloration?) and reduced eyes, filamentous multisegmented antennae and two thin filaments or hairs projecting from the tip of the abdomen. I will try to add backlit pics of the wings later if possible.
