Encrateola laevigata (Ratzeburg, 1848) (Fig. 46 A–B)

Just like the abovementioned Acrolyta spp. this species belongs to the subtribe Acrolytina . The genus Encrateola can be recognised by the surface of its mesoscutum (polished or subpolished) and its notaulus (reaching to center of mesoscutum) ( TOWNES, 1970a).

Encrateola laevigata has an open areolet and typical propodeal carination (vertical carination beneath the costula is missing; see Fig. 46 B). Its ovipositor is slightly widened subapically, with a distinctly raised nodus. The sheaths are as long as the hind tibiae. Additionally, the temples are slightly narrowed behind the eyes (Fig. 46 A) and the penultimate flagellar segment is as long as wide ( HORSTMANN, 1998b). It has a very wide host range with many common species (see SCHWARZ & SHAW, 2000; YU et al., 2012).

First report for Belgium; confirmed in the Netherlands.
