Hello, is it possibe to distinguish between Sapromyza sp. and Chyromyidae? I guess it is difficult, but maybe there is chance :-) Click on the image to get a larger version of the image.  Faulfliege ? (Lauxaniidae) by Sven, auf Flickr Location: Badberg, Oberbergen, Kaiserstuhl, Germany (close to Freiburg and Colmar) Date of discovery: 2020 June 11 Size: approx. 0,5 mm Thanks a lot.

The strong dorsal preapical britles on the tibiae are not present in Chyromyidae.

In Chyromyidae they are usually yellow to brown. Tibiae have preapical bristles, absent in Chyromyidae. Two pairs of reclinate fronto-orbital bristles are the normal condition in Lauxaniidae but Chyromyidae often have three. Most Chyromyidae have weak vibrissae. |
