Diagnosis

Alloxysta aperta is mainly characterized by a closed radial cell that is 2.4 times as long as wide (Fig. 4.2); the absence of pronotal and propodeal carinae; and female antenna with rhinaria beginning on F4, F1 slightly longer than pedicel, and F1–F3 subequal in length (Fig. 2.2). It is similar to A. quedenfeldti , but they differ in the proportion of pedicel–F1 (F1 is longer than pedicel in A. aperta (Fig. 2.2), but subequal to pedicel in A. quedenfeldti (Fig. 3.8)) and where rhinaria begin (on F 4 in A. aperta (Fig. 2.2), but on F 3 in A. quedenfeldti (Fig. 3.8)).
