Diagnosis

Alloxysta melanogaster is mainly characterized by a partially open radial cell that is 2.3 times as long as wide (Fig. 4.23); the presence of pronotal and propodeal carinae; female antenna with rhinaria beginning on F3, F1 subequal to pedicel, F1 longer than F2, F2 subequal to F3, and F4 longer than F3 (Fig. 2.27); male antenna with rhinaria beginning on F2, F1 longer than pedicel and F2, and F2–F4 subequal in length. It is similar to A. longipennis , but can be differentiated by the proportions of the flagellomere in females (F1 is subequal to pedicel in A. melanogaster (Fig. 2.27), while F1 is longer than pedicel and F2 and F2 is subequal to F 3 in A. longipennis (Fig. 2.24)) and the size of the radial cell (2.3 times as long as wide in A. melanogaster (Fig. 4.23) but 2.6 times in A. longipennnis (Fig. 4.20)).
