Diagnosis. Alloxysta victrix is mainly characterized by closed radial cell, presence of pronotal carinae, and absence of propodeal carinae. In Serbia and Montenegro it is similar to A. fuscicornis , but can be differentiated by (i) the size of radial cell, radial cell of A. victrix is longer ( Fig. 9 ) than in A. fuscicornis ( Fig. 13 ), and by (ii) the extent of propodeal pubescence (in A. victrix the propodeum lacks setae in the longitudinal area where the carinae are present in Charipinae , while A. fuscicornis has the propodeum completely covered with dense setae).

Short redescription. Head dark yellow, mesosoma and metasoma dark brown; scape, pedicel, F1 and F2 yellow and F3–F12 yellowish brown; legs yellow and veins brown. Female antennae 13-segmented; F1 and F2 smooth and thinner than remaining flagellomeres, F3–F12 club-shaped, with rhinaria; F1 longer than pedicel and F2, F2–F4 subequal ( Fig. 18 ). Male antennae 14-segmented similar to female but with F1–F3 curved (F1 slightly curved while F2 and F3 distinctly curved). Pronotum covered with sparse setae, with a pair of carinae clearly visible. Propodeum without carinae, abundantly pubescent; setae are absent at the longitudinal area where carinae are present in other Charipinae ( Fig. 26 ). Forewing longer than body, radial cell closed, 3.0 times as long as wide ( Fig. 9 ).

Distribution. Cosmopolitan. New record for Serbia and Montenegro.
