I believe that this is Fannia but I am not 100% certain. Thank You for your Time and Effort johnes81 attached the following image: [94.98Kb] John and Nini. Naturalists not experts.

Member Location: Berlin, Germany Posts: 1978 Joined: 15.10.16	consulting the following material: Lindner Der Fliegen der Palaearktischen Region Band 2 63b. Muscidae, Tafel 1 - figure 8 I think that the genitalia resembles the drawing of Fannia canicularis variation (pubescens from Stein). what is the status of this variation? this was debated over 50 years ago. Certainly something has changed by now, yes? I understand that a few dipterists have discussed this species and conclude that it is a variation of Fannia canicularis. Hennig mentions that this variation has no yellow on the tergites. Could this be the variation? John and Nini. Naturalists not experts.

Member Location: Berlin, Germany Posts: 1978 Joined: 15.10.16	Thank You for replying, Paul. I will look at this tomorrow. I am clearing the genitalia and the sternites for better viewing. I'll rexamine this specimen with Fannia aquilineata in focus. I need to make better photos of the genitalia, especially in lateral view... Thank You. John and Nini. Naturalists not experts.

Member Location: Berlin, Germany Posts: 1978 Joined: 15.10.16	Dear Paul, at first I couldn't figure out how you arrive at F. aequilineata because I have been using the work of Hennig to identify this fly. The drawings of Hennig do not match anything. Today, my Wife and I have spent hours researching Fannidae. We found the document from Fonseca. The genitalia only matches Fannia aequilineata of fonseca not Hennig. The keys/description are inconclusive because the anterior prealar doesn't seem to be strong in my opinion. The hind tibia seems to match but the midtibia is questionable. The genitalia look most like Fannia aequilineata but not exactly. Yet no other genitalia looks like this, so it must be Fannia aequilineata. Fannidae are very difficult to key. I've spent hours looking at this one. I am tired. Thank You for helping Paul. I really needed a hand with this one. Edited by johnes81 on 18-10-2017 20:20 John and Nini. Naturalists not experts.
