Thread subject: Diptera.info :: Thaumatomyia- very curious position

I found this small Thaumatomyia in this very curious position in the wall of my house, urba zone with street trees (Gleditsia, Ligustrum and Robinia), Zaragoza, Aragon, Spain, 200 meters high, continental-mediterranean. The fly sizes about 1'5 mm. After photograph it, I saw that the fly was dead.

I would like to be sure of the genus and if it's possible, an species approximation.

Hello... someone must know it... :|

I believe it is Thaumatomyia - the colouration and the very flat-topped scutellum suggest that it is that genus, but I cannot be certain of the species. The appearance of the fly is typical of one that has been attacked by Entomophthora (=Empusa) fungus. I don't know if this is the same species of fungus that attacks Melanostoma, Scathophaga and Muscidae (the flies we often see attacked)

Perhaps Thaumatomyia glabra

THANKS TO BOTH!!!! I also think that is attacked by fungus...

Th. glabra is not cited in Spain. They're cited Th. czernyi (syn= quadrimaculata), Th. notata, Th. rufa (syn =nigrovittata) and Th. sulcifrons (syn= aragonensis). Is one of the four species possible?
Thanks

If the key in Bei-Bienko is reliable at this point, then all of the above can be excluded except czernyi but that is only because it is not included in the key. With the shape of the black part on the occelar triangle I am not certain it is Thaumatomyia when I have looked at that key.

I think this is not Thaumatomyia.

Thanks,
What genus could be probable, then?
