MATERIAL EXAMINED. — (11♀). M09-BOR1400- T3 -M1: 4♀ ; M09-BOR1400- T5 -M1: 1♀ ; M09-BOR2000- T4 -M1: 2♀ ; M09-SES2000- T3 -M1: 1♀ ; M09-SES2000- T5 -M1: 1♀ ; M10- CAI2000- T1 -M1: 1♀ ; M10-CAI2000- T3 -M1: 1♀. Material deposited at MNHN, except for 5♀ deposited at UB .

DISTRIBUTION. — Previously known from Finland ( Hellén 1963). First record from France.

HOSTS. — Unknown.

DIAGNOSIS. — Alloxysta brachycera is characterized by: a completely open radial cell, 2.7 × longer than wide ( Fig. 3C ), pronotal carinae present, propodeal carinae absent, female antenna with rhinaria beginning from F4, F1 longer than pedicel and F2, F2 longer than F3, F3 shorter than F4 ( Fig. 2C ). Male unknown. Similar to Alloxysta nigrita ( Thomson, 1862) , but the two species can be differentiated by: F2 longer than F 3 in A. brachycera ( Fig. 2C ), whereas F2 is shorter than F 3 in A. nigrita ( Fig. 2N ); proportions of radial cell: 2.7 × longer than wide in A. brachycera ( Fig. 3C ), versus 2.9 × in A. nigrita ( Fig. 3N ).
