 in Exoprosopa the spots on wings have more clear limits than Thyridanthrax? Is it correct?

 there is a problem...
I have the specimen, and the sternites I and II are clearly brownish in color. it is not possible to be any artifact or loose of scales.. According to Seguy key this would be T. fenestratus.

Another data: the halteres are all whitish.

 look at the squamae, whitish (perspicillaris) or blackish (fenestratus). wing pattern of Exoprosopa very variable, in some no real pattern at all

 squamae are clearly whitish. So T. perspicillaris. But the colour of sternites don't fit. Is it very variable?
