Aphidius megourae Starý, 1965

M a t e r i a l. 1 ♀, Kyiv, Feofania [50°20'35.36'' N, 30°27'53.06'' E], forest (edges and glades), 22.06.200 7 (A. Kotenko) (SIZK).

С o m p a r a t i v e n o t e s. A. megourae belongs to the group of Aphidius species with tentorial index 0.5–0.6 ( Starý, 1973). A. megourae ( fig. 2, 1–6 ) is similar to A. funebris Mackauer ( fig 2 , 7 –12), from which it differs by: 1) more convex temples; 2) antenna with 19–20 segments; 3) narrower and longer central cell (fused1st discal, 1st and 2nd submarginal cells) of forewing; 4) narrower areola on propodeum; 5) more elongated petiole: 3.6–3.8 times as long as wide at spiracles level; 6) ovipositor sheath less sharp and almost not thinned at apex; 7) host range.

H o s t s. Megoura viciae on Lathyrus pratensis and Vicia cracca is the main host ( Starý, 1965, 2006; Tobias, Chiriac, 1986; Yu et al., 2012). For a long time A. megourae considered being monophagous, but now there are information about its parasitizing on Acyrthosiphon pisum , Aphis craccivora , and A. fabae (Yu et al., 2012) .

H a b i t a t s. Wet meadows, clearings in woods and in pathways ( Starý, 1965), pasture meadows, roadsides ( Starý, 2006), mixed forests: edges and glades.

D i s t r i b u t i o n. Ukraine (Kyiv Region, first record). Europe: France, Poland, Czech Republic, Slovakia, Hungary, Moldova, Russia (Moscow Region) ( Tobias, Chiriac, 1986; Yu et al., 2012).
