Alloxysta abdera Fergusson, 1986: 10 . Type: deposited in BMNH (examined).

Diagnosis

Alloxysta abdera is mainly characterized by a completely open radial cell that is 2.2 times as long as wide in both males and females (Fig. 4.1); the presence of pronotal and propodeal carinae; female antenna with rhinaria beginning on F4, F1 longer than the pedicel and subequal to F2, F2 longer than F3, and F3 slightly longer than F4 (Fig. 2.1); male antenna with rhinaria beginning on F2, F2 curved, F1 longer than pedicel and F2, F2 shorter than F3, and F3 subequal to F4. It is similar to Alloxysta pallidicornis ( Curtis, 1838) , but can be differentiated by the flagellomere proportions in females (F2 is longer than F3 and F3 is slightly longer than F 4 in A. abdera (Fig. 2.1), but F2–F4 are subequal in length in A. pallidicornis (Fig. 2.32)), the shape of the propodeal carinae (they form a plate with setae on top and sides slightly curved in A. abdera , while the two carinae are well-defined, separated anteriorly, and joined at the base in A. pallidicornis ), and the size of the radial cell (2.2 times as long as wide in A. abdera (Fig. 4.1) but 2.6 times in A. pallidicornis (Fig. 5.4)).
