No, there's still only one. So far, no differences in the Qsp and Qn wings
have been found that aren't related solely to structural requirements due to
the size difference. I personally doubt they are the same species, but that
isn't my field, or my choice. Titanopteryx doesn't appear to be a synonym
because its cervical vertebra is somewhat different from the Qsp vertebrae,
while the Qn wing (about 40% of the left wing extant) is quite similar to the
Qsp wing (about ten specimens extant). But I leave that sort of choice to
others with more experience in making those decisions. I work only on the
mechanics of the two animals, which I have to treat seperately because of the
size allometries. Qsp doesn't scale up isometrically to Qn.
