Reinoud, I'm sorry to say that it is mainly "the look" (at least in a dorsal view). The head is rather angled forward and it has long, 'floppy' antennae; also the generalized venation (which in Ancylorrhynchus, cell m3 can be open or petiolate) and the 'bare' look of the body & legs (inconspicuous setae). Key to spp. (in Israel): Theodor 1980.

Cheers & very best wishes for a great 2017!
