This is probably an unavoidable side effect of the slide mounting preferred by Disney ... once a specimen is mounted according to his recommendations for Megaselia, you are restricted to the lateral views of the genitalia, and the hypandrium, usually best seen from a ventral view, is poorly visible.
And there is no guarantee that all slide-mounted genitalia will look exactly the same. With the amount of experience someone like Disney has it is possible to interpret the differences, we mere mortals are less fortunate. I rarely succeed in identifying one to species level because I do not slide-mount them. That leaves a lot of room for interpreting the lateral view of the genitalia the wrong way.
