Polyaulon paradoxus (Zetterstedt, 1838) View in CoL (Fig. 51 A–B)
An extraordinary genus comprising ichneumonids which have the second and third tergite fused into a single large sclerite, often forming a very smooth area as in for example Proctotrupidae . Additionally, the mandibular outlines are not convex and have no transverse furrow at the base ( SCHWARZ, 1995; HORSTMANN, 1998b). Polyaulon paradoxus has apterous females and is completely testaceous, except for the somewhat darker head (Fig. 51 A–B). This species is rarely reported, which could be due to its ecology connected to arachnids.
First report of the species and the genus for Belgium; confirmed in the Netherlands.
