Sathropterus pumilus (Holmgren, 1860) (Fig. 66 A–B)

This is a somewhat easier species to key within Tersilochinae , being the only one in the genus. Its wing veins in the fore wing are thickened around 2rs-m, glymmae are present and the propodeum has longitudinal carinae medially. More importantly, the brachial cell of the fore wing is widely open at apex, the fore wing vein 2m-cu is completely absent (Fig. 66B) and the ovipositor tip is sinuate ( KHALAIM & YURTCAN, 2011; Fig. 66A).

First report of the species and the genus for Belgium; confirmed in the Netherlands.
