Diagnosis

Alloxysta leunisii is mainly characterized by a closed radial cell that is 2.0 times as long as wide (Fig. 4.19), the presence of pronotal carinae, the absence of propodeal carinae, antenna with rhinaria and club shape beginning on F 2 in females and F 3 in males, female antenna with F1 longer than pedicel and subequal to F2 and F3 (Fig. 2.23), and male antenna with the same proportions as females except that F3 is longer than F2. It is similar to A. consobrina , but can be differentiated by the place where rhinaria begin in females (F 2 in A. leunisii (Fig. 2.23) and F3/F 4 in A. consobrina (Fig. 2.14)), flagellomere shape in males (F1 is slightly curved in A. leunisii while F1–F3 are strongly curved in A. consobrina ), and the size of the radial cell (2.0 times as long as wide in A. leunisii (Fig. 4.19) but 2.7 times in A. consobrina (Fig. 4.12)).
