Type : deposited in BMNH (examined). Diagnosis Alloxysta semiaperta is mainly characterized by a partially open radial cell that is 2.7 times as long as wide (Fig. 5.17); the presence of pronotal carinae; the absence of propodeal carinae; and antenna with rhinaria and club shape beginning on F 3 in females and F 4 in males, F1 longer than pedicel and F2, F2 shorter than F 3 in females and subequal in males, and F3 shorter than F4 (Fig. 3.13). It is similar to A. salicicola , but can be differentiated by the length-to-width ratio of the flagellomeres, which is greater in A. salicola .
