* Alloxysta salicicola Belizin, 1973

Material examined (1 ♀). SLOVENIA: unknown aphid and primary parasitoid on Leontodon hispidus, Šempeter , 17.vi.2009: 1 ♀ deposited in UB.

Diagnosis. Alloxysta salicicola is characterized by partially open radial cell ( Fig. 14 ), pronotal carinae, and smooth propodeum. It is similar to A. macrophadna , but can be easily differentiated by (i) the proportion of the lengths of flagellomeres: F2–F4 subequal in A. salicicola ( Fig. 24 ), but not subequal in A. macrophadna ( Fig. 16 ); and by (ii) size of radial cell: 2.6 times as long as wide in A. salicicola ( Fig. 14 ) whereas it is 3.3 times as long as wide in A. macrophadna ( Fig. 6 ).

Short description. Head, mesosoma and metasoma brown; scape, pedicel and F1 dark yellow, F2–F11 yellowish brown; legs yellow; veins yellowish brown. Female antennae 13- segmented; F1–F2 thinner and smoother than remaining flagellomeres, F3–F11 club-shaped, with rhinaria; F1 longer than pedicel, F1 longer than F2, F2–F4 subequal ( Fig. 24 ). Male unknown. Pronotum covered with numerous setae, with two carinae present. Propodeum smooth, densely haired. Forewing longer than body; radial cell partially open, 2.6 times as long as wide ( Fig. 14 ).

Distribution. Palaearctic Region. New record from Slovenia.
