Hello Rei,
about the
femorata vs
dioctriaeformis , I've also red the dubts about the existence of the last one (that still appears to exist taxonomically), but what appears to me clear in this specimen is the abundance of hairs along tergites, a thing unusual for
femorata, that some authors ascribe to
dioctriaeformis . Using a "dubtful" species ID is risky, but I couldn't find
femorata much convincing so I've chosen
dioctriaeformis.
DNA would be a great way to track species fingerprint, and moreover, I think there can be an explosion of species. A nice way can be to set the minimum set of genes (with aesthetic effect) inside a particular genus with quite preserved sequences (a kind of genus fingerprint, that means--> reduce operator-dependency, subjectivity, and increase reproducibility and objectivity), establish a cut-off of variability, and so screen a array of specimen. The only problem, aside the time consumption, is the €€€€ consumption, and I'm afraid that there's not too much business-interest in this family, that I personally like and appreciate very much. Some genus is sporadically studied as bio-defense against pests, but quite often is abandoned due to scarce prey-specificity (that means that they also attack "useful" insects).
