Dear Igor,
both specimens key to species-group IV (femora black; lower postocular setae white).

I noticed that you published quite a lot about this genus, unfortunately most of the articles I have no access to. However, in the "checklist and keys to Dolichopodidae (Diptera) of the Caucasus and East
Mediterranean" both of my flies, male and female, key perfectly to H rusticus:

Male - Calypter with black cilia; Postpedicel twice as long as broad; hind basitarsus shorter than 2nd
Female - Calypter with black cilia; Postpedicel 1,5x longer than broad; hind basitarsus shorter than 2nd

I wonder if you know if there are any Middle European species that, based on these features, can be confused with H rusticus.

Best, Lorin
