Looks lke a female Platymyia fimbriata, however, the inner edge of calypter is not darkened ?? So we have two options 1. The inner edge is darkened, but does not show darkened 2. the second (apparent first) segment of arista is somewhat elongated, the barrette is hairy and the calypter is “ballonish”, in which case it is Paratryphera barbatula. The barrette is the elongated strip just anterior of the posterior spiracle. It is clearly visible in the second pic, but I can’t tell if it hairy.. Theo |

Thanks a lot! Not so easy to see even under a microscope, but the barette seems to be bare. Calypter may not be balloonish - but more like a plate. Then maybe it's Platymyia fimbriata after all... Rosevinge |

My doubt was legit: the eye is bare. I just assumed it to be hairy. So we need to start all over. Theo |

so, one apical scutellar britslte is erect and the other is not. I assumed the erect one to be artificial, but it might be vice versa. There is one strong bristle at base of vein R in the wing, indicating Lydella. Wing venation is consistent. The not appressed hairs on tergites, general colouration, width of vertex (narrow for a female Lydella) and slightly concave facial ridge in lower part (very subtle !) then proves Lydella stabulans.
