Belongs within: Systasidae.
Systasis is a cosmopolitan genus of wasps of uncertain biology: they may parasitise insect larvae within galls, or they may be gall-formers themselves (Bouček 1988).
Characters (from Bouček 1988): Body with more or less distinct metallic tinge; antenna with seven segments between pedicel and clava; thoracic dorsum usually lacking coarse punctures, usually with dense reticulation (and then dull) or very dense but fine puncturation; propodeum deeply reticulate; forewing with rather sparse pilosity, with a large speculum anteriorly reaching virtually the distal end of the marginal vein, thus making conspicuous a row of longish hairs on the underside, below the marginal vein; marginal vein more than twice as long as stigmal, postmarginal vein usually only slightly longer than the stigmal; legs usually more or less infuscate.
