Phradis nigritulus (Gravenhorst, 1829)

Phradis spp. are small and robust species with the wing veins thickened around 2rs-m. Their propodeum has one or two median longitudinal carinae, and the first tergite does not have glymmae ( KHALAIM & YURTCAN, 2011).

Phradis nigritulus is a smaller species (2–4 mm and 11–12 flagellomeres) with its ovipositor sheath 1.6–1.8× as long as the first tergite. The second recurrent vein is present, but it is only pigmented in its anterior part. The dorsolateral areas of the propodeum are smooth and shiny. Its basal flagellomeres are relatively stout and its ovipositor has a narrow dorsal subapical notch ( KHALAIM et al., 2009). First report for the Netherlands; unreported in Belgium.
