Ethelurgus balearicus (Kriechbaumer, 1894)

Ethelergus is a smaller genus. Next to the apical truncation of the scape, which is very oblique, their area superomedia is much wider than long, and small. The females have a short ovipositor tip, compressed and somewhat decurved, with a strong nodus ( TOWNES, 1970a).

E. balearicus can be distinguished from E. sodalis by the length of its fourth antennal segment (more or less 3.0x as long as wide), its red hind coxae and its fine punctuation of the second tergite. Our specimen had 22 antennal segments ( HORSTMANN, 2000).

First report for Belgium; unreported in the Netherlands.
