Dear friends,
these shots are not mine, taken by Vladimir Dmitriev 2009:05:06 in Dalnegorsk (Far East of Russia). As I know, Haruka elegans (Okada, 1938) occurs in Japan only. So, could it be Pergratospes holoptica (Krivosheina and Mamaev, 1970)?

Sincerely,
Dmitry Dolivo-Dobrovolsky

BTW, cannot find any of these families in the "Diptera classification" section, so I'm not sure about modern/preferred classification: Pachyneuridae or Cramptonomyiidae?

The key character (R2+3 diverges from Rs a lot more distally of rm) is quite visible, IMHO, male's eyes are close together so P. holoptica (Pachyneuridae)

Beautiful photographs ! Nice to see these mythical flies. Is Pergratospes holoptica a frequent species in Primore Krai ?

Unfortunately, I don't know, we are not entomologists... However, I asked Vladimir to collect these flies, if possible. BTW, Dalnegorsk is about 250 km from the Far East Ussuriysky reservation (the origin of at least three pinned specimens in Mamaev's collection).
