From Bei-Bienko:

Posterior half of frons with snow white coating, Mesonotum brownish yellow. Wings with dark spot on subcostal cell, broad brown border in apical half of wing [...] and similar broad border on posterior crossvein.... Palloptera venusta.

Hence, I think Andrey Ozerov is right to think this is Toxoneura (or, Palloptera) venusta.

On a side note: this once again makes me think that one almost never should trust the keys in Bei-Bienko when it comes to describing the colour of the thorax, I guess different colours of brown is notoriously hard to translate from russian into english?
