Diagnosis

Alloxysta xanthopa is characterized by a completely open radial cell that is 2.4 times as long as wide (Fig. 5.23); the presence of pronotal carinae; propodeal carinae that form a plate; and antenna with rhinaria beginning on F3, F1 longer than pedicel and slightly longer than F2, F2 shorter than F3, and F3 subequal to F4 (Fig. 3.19). These features easily differentiate it from other species of Alloxysta .
