Diagnosis

This species is easily differentiated from other species of Alloxysta by the following combination of features: a partially open radial cell (Fig. 5.8); the presence of pronotal carinae; two well-defined propodeal carinae that reach the posterior margin independently; female antenna with F1 longer than F2, F2 shorter than F3, and F3 shorter than F4 (Fig. 3.4); male antenna with F1–F3 subequal in length and slightly curved.
