Dusona recta (Thomson, 1887) (Fig. 12)

Dusona recta belongs to the first group of Dusona spp. , with the epipleurum of the third gastral tergite separated from the tergite by a crease. In this case, the crease is clearly black. Our specimen measured approximately 8 mm and counted at least 39 flagellomeres (some broke off). Its genal index is 0.1–0.2 and the speculum is coriaceous, rather dull. In front of the speculum there are fine longitudinal striae medially and ventrally as well as dorsally. The hind tibiae are largely yellowish but black apically ( HORSTMANN, 2009). In our specimen, tergites 3–4 are orange red and the second tergite is partly orange, partly black (Fig. 12). Aethalura punctulata (Denis & Schiffermüller, 1775) and Ematurga atomaria (Linnaeus, 1758) ( Lepidoptera : Geometridae ) are plausible hosts ( HORSTMANN, 2011).
