Hi! How can a blackfly be determined? Should I dissect genitals? Dorsal or side-view is important? Thanks! NE Hungary, April, in forest.

I think the terminalia are not exposed in this pic:

For those who have ever wondered how a blackfly terminalia looks like after being forgotten in NaOH for 3 weeks, here it is: Still no chance to ID?

This should be
Simulium (Simulium) based on the shape of the gonostylus: longer than gonocoxite and "with apex broadly rounded and flattened paddle-like" (vs. narrowly rounded or truncate). This based on the revision of North American Simuliidae, which offers character states to justify monophyly of holarctic genera, subgenera, and species groups that are present in North America.
If the white spots are "stripes" it is in the
ornatum species group. Most species of subgenus
Simulium have unmarked scutum.
