Chalcid wasp

This is definitely a Eurytomidae (well spotted). I would suspect that it is not Bruchophagus roddi (which develops in alfalfa seeds), and that it is in the genus Eurytoma - although it can be very difficult to tell Eurytoma and Bruchophagus apart (even with a microscope). The main differentiating character is a funny little ridge on the back side of the head! At any rate I would call this Eurytoma sp. Eurytoma is a very difficult genus for identifying species. There are hundreds of species which are very difficult to tell apart.
