Tropistes nitidipennis Gravenhorst, 1829 (Fig. 53)

A smaller genus with some clear characteristics: fore wing vein 3rs-m lacking or faint, thorax compressed and unique carination on the propodeum . The metasoma of the females is also compressed and the ovipositor decurved ( TOWNES, 1970a).

T. nitidipennis has the third antennal segment slender (4.5–5.7× as long as wide). Its ovipositor is robust and distinctly bent downwards with the ovipositor tip raised subapically and strongly tapered to the apex dorsally (Fig. 53). Its tegulae are white, the hind coxae are black ( SCHWARZ & SHAW, 2011). Some of the known hosts are (remarkably) Raphidioptera-species (ASPÖCK, 2002). The ichneumonid was caught with a light trap in an urban area and is probably widely underreported. First report for Belgium; unreported in the Netherlands.
