* Alloxysta fuscicornis ( Hartig, 1841)

Material examined (6 ♀♀). SERBIA: Praon exsoletum – Therioaphis trifolii (Monell, 1882) on Medicago sativa, Kovilovo , 16.vi.2010 and 3.vi.2011: 2 ♀♀; Umčari-Donji Kraj, 8.vi.2012: 1 ♀; Osipaonica, 11.vi.2012: 1 ♀; Živkovac-Site 1, 16.vi.2012: 1 ♀; unknown primary parasitoid – Uroleucon sp. on Crepis sp. , Jakovački Ključ, 7.v.2007: 1 ♀. [5 ♀♀ deposited in UB and 1 ♀ deposited in IZFBUB].

Diagnosis. Alloxysta fuscicornis is mainly characterized by closed radial cell, pronotal carinae, and smooth propodeum. It is similar to A. victrix , but they can be easily differentiated by (i) the size of radial cell: the radial cell of A. fuscicornis is 2.7 times as long as wide ( Fig. 13 ) while the radial cell is 3.0 times as long as wide in A. victrix ( Fig. 9 ), and by (ii) the setation on propodeum: A. fuscicornis has the propodeum completely covered with dense setae while in A. victrix the propodeum lacks setae at the longitudinal area whereas the carinae are present in other Charipinae .

Short redescription. Head, mesosoma and metasoma brown; scape, pedicel, F1 and F2 yellow and F3–F12 yellowish brown; legs yellow; veins brown. Female antennae 13-segmented; F1–F3 smooth and thinner than remaining ones, F4–F12 club-shaped, with rhinaria; F1 longer than pedicel and F2, F2 longer than F3, F3 shorter than F4 ( Fig. 22 ). Male antennae 14-segmented; with the same proportions as in female but F1–F3 bowed (F1 slightly bowed while F2 and F3 clearly bowed). Pronotum covered with setae with two carinae present and clearly visible. Propodeum with abundant setae and without carinae. Forewing longer than body; radial cell closed, 2.7 times as long as wide ( Fig. 13 ).

Distribution. Cosmopolitan. New record from Serbia.
