Cerocephalidae

 Cerocephala eccoptogastri, from here.

Belong within: Chalcidoidea.

The Cerocephalinae are a group of wasps that parasitise small wood-boring beetles such as Scolytidae and Anobiidae (Bouček 1988).

Characters (from Bouček 1988): Antennae inserted always some distance above the mouth border, toruli separated by an interantennal crest which often forms a tooth; sometimes other ridges, often with teeth, are developed on either side of toruli; antennae rather shiny, with sparse pilosity and very low sensilla, often pale-coloured; eyes bare or nearly so; thorax frequently smooth, only rarely with rugosity, but propodeum always heavily sculptured, without smooth areas, except in dwarf forms in which all sculpture is obliterated. Forewing usually with strongly reduced discal pilosity but always with very conspicuous marginal fringe; short stigmal vein at a rather acute angle, postmarginal vein often shorter than stigmal. Gastral petiole sometimes long, sometimes strongly transverse; hind margin of first gastral terglte in females often emarginate or even deeply excised in the middle; ovipositor sheaths subexserted or longer, up to almost as long as the gaster. Short-winged forms common.
