Cteniscus pedatorius (Panzer, 1809)

Cteniscus belongs to the former tribe Exenterini . Its notaulus is distinct, punctures on the abdominal tergites are fine to medium sized and the area superomedia is longer than wide ( TOWNES, 1969).

Cteniscus pedatorius needs to be keyed carefully. Its pterostigma is dark brown to black with a lighter base. Its temples are more or less straight behind the eyes (dorsally). The hind tibiae are darkened apically and the tarsi are blackish ( KASPARYAN & TOLKANITZ, 1981). Several specimens discovered were associated with Nematus (Craesus) septentrionalis (Linnaeus, 1758) . More information on the Dutch rearing records can be read in ZWAKHALS & BLOMMERS, forthcoming.
