Diagnosis

Alloxysta ramulifera is mainly characterized by a small closed radial cell that is 2.0 times as long as wide (Fig. 5.13); the presence of pronotal carinae that are very small and sometimes difficult to see under the pubescence; propodeal carinae that form a plate; and antenna with rhinaria and club shape beginning on F4, F1 subequal to pedicel, F1 longer than F2, F2 subequal to F3, and F3 shorter than F4 (Fig. 3.9). Alloxysta ramulifera is very similar to A. arcuata , both species having pronotal carinae, propodeal plates, and a small and closed radial cell. They can be distinguished by the shape of the pronotal carinae (small and sometimes very difficult to see under the pubescence in A. ramulifera , but thick and clearly visible in A. arcuata ), the shape of propodeal plate (in A. ramulifera the carinae are straight, are separated by setae in the first third, and form a plate in the last two thirds, while they form a complete plate in A. arcuata ), and the size of the radial cell (2.0 times as long as wide in A. ramulifera (Fig. 5.13), but 2.3 times in A. arcuata (Fig. 4.3)).
