Second thoughts
The more I look at this specimen, the more I am convinced that it is probably Stenacron rather than Maccaffertium. Even though the dark cross veins in the radial space near the bulla are not connected or as prominently spotted as is usually described or figured, the pleural streaks and face markings seem to suggest that this might be just another version of the common, but highly variable S. interpunctatum.
