* Alloxysta macrophadna ( Hartig, 1841)

Material examined (3 ♀♀). MONTENEGRO: Aphidius sussi – Delphinobium junackianum on Aconitum toxicum Crno jezero, 19.vii.2000: 1 ♀. SERBIA: unknown aphid and primary parasitoid on Medicago sativa, Besni Fok , 13.vi.2011, 6.x.2011: 2 ♀♀. [2 ♀♀ deposited in UB, 1 ♀ deposited in IZFBUB].

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

Short redescription. Head yellowish red, mesosoma and metasoma dark brown; scape, pedicel and F1–F3 yellow, the remaining ones brown yellowish; legs yellow; veins dark brown. Female antennae 13-segmented; F1–F3 smooth and thinner than remaining ones, F4–F11 club-shaped, with rhinaria; F1 longer than pedicel, F1 longer than F2, F2 shorter than F3, and F3 shorter than F4 ( Fig. 16 ). Male antennae 14-segmented; F1–F2 smooth and thinner than remaining ones, F3–F12 club-shaped, with rhinaria; F2 and F3 clearly curved; F1 longer than pedicel, F1 subequal to F2, F2 longer than F3, and F3 longer than F4. Pronotum densely covered with short setae, with two long carinae under the pubescence. Propodeum without carinae, densely covered by setae. Forewing longer than body, radial cell partially open, 3.3 times as long as wide ( Fig. 6 ).

Distribution. Palaearctic Region. New record from Montenegro.
