Diagnosis. Alloxysta pleuralis has partially open radial cell ( Fig. 7 ), and pronotal and propodeal carinae. It is similar to A. castanea , but can be easily differentiated by the shape of the propodeal carinae, which are well defined and reach the base independently in A. pleuralis , but form a plate in A. castanea .

Short redescription. Head dark yellow, mesosoma yellowish brown and metasoma dark brown; scape, pedicel, F1–F3 dark yellow and F4–F12 yellowish brown; legs and veins yellowish brown. Female antennae 13-segmented; F1 and F2 smooth and thinner than remaining ones, F3–F11 club-shaped, with rhinaria; F1 subequal to pedicel, F1 longer than F2, F2 shorter than F3, F3 shorter than F4 ( Fig. 23 ). Male antennae 14-segmented; F1–F12 club-shaped, with rhinaria; F1–F3 slightly curved; F1 longer than pedicel, F1–F4 subequal in length. Pronotum covered with setae with two thick carinae clearly visible. Propodeum covered with setae, with two thick well defined carinae reaching the base independently and with curved lateral sides. Forewing longer than body; radial cell partially open, 2.1 times as long as wide ( Fig. 7 ).

Distribution. Palaearctic Region. New record from Serbia and Slovenia.
