Diagnosis. Alloxysta castanea has partially open radial cell ( Fig. 5 ) and pronotal and propodeal carinae present. It is similar to A. pleuralis , but they can be easily differentiated by the shape of propodeal carinae, which form a plate in A. castanea but are well defined and reaches the base independently in A. pleuralis .

Short redescription. Head yellowish brown, mesosoma brown, metasoma dark brown; scape, pedicel, F1 and F2 yellow, F3–F11 brown; legs yellow; veins yellowish brown. Female antennae 13-segmented; F1 and F2 smooth and thinner than other segments, F3–F11 club-shaped, with rhinaria; F1 longer than pedicel and F2, F2–F4 subequal in length ( Fig. 15 ). Male antennae 14-segmented; as female but with F1 and F2 slightly curved. Pronotum densely pubescent with two carinae clearly visible. Propodeum densely covered with long setae bearing a pair of carinae forming a plate with slightly curved lateral sides, sparsely setose on the top. Forewing longer than body, radial cell partially open, 2.4 times as long as wide ( Fig. 5 ).

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