( Figs 2Q ; 3Q )

Xystus posticus Hartig, 1841: 352 .

MATERIAL EXAMINED. — (9♀). M9-BOR1400- T1 -M1: 1♀ ; M9-BOR1400- T2 -M1: 1♀ ; M9-BOR1400- T4 -M1: 1♀ ; M9- SES1400- T2 -M2: 1♀ ; M9-SES1400- T3 -M2: 1♀ ; M9-SES1400- T6 - M2: 1♀ ; M9-SES2000- T3 -M1: 1♀ ; M10-CAI1400- T6 -M2: 1♀ ; M10-CAI2000- T7 -M2: 1♀. 5♀ deposited at MNHN and 5♀ at UB .

DISTRIBUTION. — Species previously known from the Palaearctic region (Ferrer-Suay et al. 2012a). First record from France.

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

DIAGNOSIS. — Alloxysta postica is characterized by: a partially open radial cell, 2.5 × longer than wide ( Fig. 3Q ); pronotal carinae and propodeal carinae present; female antenna with rhinaria beginning from F4, pedicel-F4 subequal in length ( Fig. 2Q ). Male unknown. Similar to A. citripes , but the two species can be differentiated by the shape of propodeal carinae: clearly visible and forming a plate in A. postica , whereas the carinae are not protruding in A. citripes ( Fig. 6F ); proportions of radial cell 2.5 × longer than wide in A. postica ( Fig. 3Q ) but 2.1 × in A. citripes ( Fig. 3G ).
