Hello, Black!
No Tipulidae, I think, but
Ptychopteridae.

Hi Black,
J?rgen thinks right, it is a Ptychopteridae. Could be
Ptychoptera contaminata, but I have too little experience with Ptychopteridae to be sure about that.

Thanks a lot Juergen and Jan. So that's why I couldn't go anywhere with Tipulidae genus key...

Hello!
Yesterday I found this one. Could be a female of the same species (?).

I have Alan Stubss's key in front of me and it clearly identifies the pictures of the first specimen as P. contaminata. This key uses features of the venation at the base of the wing, whcih are visible here (but not in most other pictures of Ptychopteridae).
Also the shape of the styles is distinctive, with the 'hearts' shaped space between them in contaminata.
Therefore i think the second male is also contaminata; and also because contaminata and albimana are the commonest species, and the latter has whitish hind basal tarsi, best visible in females. So J?rgen's female is not albimana, and quite possibly contaminata too.
