Ophion ocellaris Ulbricht, 1926 (Fig. 42 A–B)

Ophion ocellaris is a species with a longer history. It appears very early in keys because it is easily recognisable. The occipital carina is completely absent (Fig. 42 B). Furthermore, its stemmaticum is black or dark brown (Fig. 42 A–B), its area superomedia is absent with transverse wrinkles in its place and it has over 50 flagellomeres. The species appears to fly earlier in the year in the Low Countries than in Sweden ( JOHANSSON & CEDERBERG, 2019).

First report for Belgium; confirmed in the Netherlands.
