I am looking for confirmation of the genus. I have microscopic photos if species level can be reached. I will post as necessary. I am thinking Ophiomyia nasuta... Also, I would like to know if any keys exist for Palearctic species. Is there an expert around in the forums? Thank You for your Time and Effort. I appreciate the help. johnes81 attached the following image: [70.84Kb] Edited by johnes81 on 10-09-2017 23:47 John and Nini. Naturalists not experts.

I thought that it was Agromyzidae. Thank You so very much. I hope to help you with something in return someday. This is a very interesting fly, so I want to read more about it. Unfortunately, this one is a female. I had trouble dissecting the very tiny ovipositor. I will try to find a male specimen. John and Nini. Naturalists not experts.

So could this be Desmometopa varipalpis? I can show the legs but I need to collect the photos. I'll post more data... John and Nini. Naturalists not experts.

Member Location: Berlin, Germany Posts: 1978 Joined: 15.10.16	After many hours of research and a male specimen, my Wife and I conclude that this species is Desmometopa m-nigrum based upon the work of Sabrosky 1983. Some of the details are off a bit but overall it is a match. I had to dissect the very tiny palpi (unbelievably difficult to me.) I also dissected the male genitalia. I cannot find a better match for this than m-nigrum. Thank You Stephane. John and Nini. Naturalists not experts.
