Diagnosis

Alloxysta arcuata is mainly characterized by a small closed radial cell that is 2.3 times as long as wide (Fig. 4.3); the presence of pronotal carinae (Fig. 8.1); propodeal carinae that form a plate (Fig. 9.1); female antenna with rhinaria beginning on F3, F1 subequal to pedicel and longer than F2, and F2 subequal to F3 (Fig. 2.4); male antenna with rhinaria beginning on F2, F2 slightly curved, F1 longer than pedicel, F1 subequal to F2, and F2 shorter than F3. It is similar to A. ramulifera , but can be differentiated by the origin of the rhinaria (on F 3 in A. arcuata (Fig. 2.4), but on F 4 in A. ramulifera (Fig. 3.9)), the shape of the pronotal carinae (well-defined and visible in A. arcuata but small and sometimes difficult to see under the pubescence in A. ramulifera ), the size of the radial cell (2.3 times as long as wide in A. arcuata (Fig. 4.3), but 2.0 in A. ramulifera (Fig. 5.13)), and the shape of the propodeal carinae (with curved sides in A. arcuata but with straight sides in A. ramulifera ).
