Diagnosis

Alloxysta postica is mainly characterized by a partially open radial cell that is 2.5 times as long as wide (Fig. 5.9), the presence of pronotal carinae and propodeal carinae, female antenna with rhinaria beginning on F4, and pedicel–F4 subequal in length (Fig. 3.5). It is similar to A. citripes , but they can be differentiated by the shape of the propodeal carinae (clearly visible and forming a protruding plate in A. postica while not protruding in A. citripes ) and the size of the radial cell (2.5 times as long as wide in A. postica (Fig. 5.9), but 2.1 times in A. citripes (Fig. 4.11)).
