For more pictures of this female Tycherus ophtalmicus see:
It is 6,0 mm long and handpicked on Angelica sylvestris 29/7-2016.
It is a bit smaller (may be because of the upright petiolus) than the size for this one both in Perkins and Ratsnitsyn (6,5 - 8 mm).
I have even got another female that is almost 1 mm shorter, that have the same carinae on coxae 3, and elevated occipital carina just before mandible base.
May be I will have to wait for a revision of Tycherus and Phaeogenes before a conclusion on especially the smaller one (not posted yet).
