Diagnosis

Alloxysta crassicornis is mainly characterized by a closed radial cell that is 2.6 times as long as wide (Fig. 4.14); the presence of pronotal carinae; propodeal carinae that form a plate with slightly curved margins; and antenna with rhinaria and club shape beginning on F3, F1 subequal to pedicel and slightly longer than F2, and F2–F4 subequal in length (Fig. 2.16). According to these features, A. crassicornis is very similar to A. arcuata , but can be differentiated by flagellomere proportions (F2–F4 are subequal in length in A. crassicornis (Fig. 2.16), while F2 is subequal to F3 and F3 is shorter than F 4 in A. arcuata (Fig. 2.4)) and the size of the radial cell (2.6 times as long as wide in A. crassicornis (Fig. 4.14), but 2.3 times in A. arcuata (Fig. 4.3)).
