Figs 2.7, 4.6

Alloxysta brachycera Hellén, 1963: 14 . Type: deposited in MZH (examined).

Diagnosis

Alloxysta brachycera is mainly characterized by a completely open radial cell that is 2.7 times as long as wide (Fig. 4.6); the presence of pronotal carinae; the absence of propodeal carinae; and female antenna with rhinaria beginning on F4, F1 longer than pedicel and F2, F2 longer than F3, and F3 shorter than F4 (Fig. 2.7). It is similar to A. nigrita, but can be differentiated by the F2–F3 proportion (F2 is longer than F 3 in A. brachycera (Fig. 2.7), but shorter than F 3 in A. nigrita (Fig. 2.30)) and the size of the radial cell (2.7 times as long as wide in A. brachycera (Fig. 4.6), but 2.9 in A. nigrita (Fig. 5.2)).
