DISTRIBUTION. — Previously known from the Palaearctic (Ferrer- Suay et al. 2012b). First record from France.

HOSTS. — See Charipinae Worldwide Catalogue (Ferrer-Suay et al., 2012a).

DIAGNOSIS. — Alloxysta brevis is characterized by: a small closed radial cell, 2.1 × longer than wide ( Fig. 3D ), pronotal carina absent ( Fig. 5B ), propodeal carinae present forming a plate; female and male antenna with rhinaria beginning from F4; F1 shorter than pedicel and F1-F3 subequal in length ( Fig. 2D ). It is similar to Alloxysta darci (Girault, 1933) , but could be differentiated by: antenna shorter than body in A. brevis , versus longer in A. darci ; forewing with marginal setae shorter in A. brevis than those in A. darci .
