(syn Scelionidae) The hymenopteran family Platygastridae (sometimes incorrectly spelled Platygasteridae) is a large group (over 1100 species) of exclusively parasitoid wasps, mostly very small (1-2 mm), black, and shining, with elbowed antennae that have an eight-segmented flagellum. The wings most often lack venation, though they may have slight fringes of setae.
