Lyciscidae is a family of chalcid wasps. The genera comprising this family were previously placed in the Cleonyminae subfamily of a paraphyletic Pteromalidae.
Many species have metallic green, blue and bronze colours, and stout hind legs and fore legs. The females of most species have a tapered abdomen and a long ovipositor suited to accessing hosts concealed in wood; they are often encountered on trunks or branches of trees. Many are parasitoids of wood-boring beetles of the families Buprestidae (jewel beetles), Cerambycidae (longhorn beetles), and Curculionidae (weevils). However, some Agamerion species are parasitoids of cockroach egg masses, Epistenia species parasitize twig-nesting aculeate wasps and bees, and Marxiana grandiosa is a hyperparasite of braconid wasps (which are, in turn, parasitoids of wood-boring beetles).
