Diagnosis

Alloxysta crassa is mainly characterized by a completely open radial cell that is 2.8 times as long as wide (Fig. 4.13); the presence of pronotal carinae; the absence of propodeal carinae; antenna with rhinaria and club shape beginning on F4, F1 longer than pedicel and slightly longer than F2, and F2–F4 subequal in length (Fig. 2.15). It is similar to A. brachycera , but can be differentiated by the F2–F3 proportion (F2 is subequal to F 3 in A. crassa , while F2 is longer than F 3 in A. brachycera ).
