Diagnosis

Alloxysta pusilla is mainly characterized by a closed radial cell that is 2.7 times as long as wide in females (Fig. 5.11) and 2.4 times in males; the presence of pronotal and propodeal carinae that form a plate; female antenna with rhinaria beginning on F3, F1 longer than pedicel and F2, F2 shorter than F3, and F3 shorter than F4 (Fig. 3.7); male antenna with rhinaria beginning on F1, pedicel–F3 subequal in length, F4 longer than F3, and F1–F3 slightly curved. It is similar to A. pilipennis , but can be differentiated by the proportions of the flagellomere in females (F2 is shorter than F 3 in A. pusilla females (Fig. 3.7), but subequal to F 3 in A. pilipennis females (Fig. 3.3)), flagellomere proportions and shape in males (F1–F3 are subequal in length and slightly curved in A. pusilla males, but F1–F3 are not subequal and not curved in A. pilipennis males), and the size of the radial cell (2.7 times as long as wide in A. pusilla females (Fig. 5.11), but 2.4 times in A. pilipennis females (Fig. 5.7)).
