Diagnosis

Alloxysta piceomaculata is mainly characterized by an open radial cell that is 2.8 times as long as wide; the presence of pronotal carinae; the absence of propodeal carinae; and antenna with rhinaria and club shape beginning on F4, F1 longer than pedicel and F2, F2 shorter than F3, and F3 subequal to F4. It is similar to A. nigrita , but can be differentiated by the proportion of the F3–F4 (F3 is subequal to F 4 in A. piceomaculata (Fig. 3.2), while F3 is longer than F 4 in A. nigrita (Fig. 2.30)) and the shape of the radial cell (R1 and Rs do not reach the margin of the fore wing in A. piceomaculata (Fig. 5.6), but do reach it in A. nigrita (Fig. 5.2)).
