Overview:

 

Bouček (1988) discussing the characteristics of a chalcid stated that "All chalcids have the wing venation greatly reduced, generally to one linear vein, without any closed cells, but such reduction is found also in some other groups. Another important feature is found on the anterior part of the thorax; the prepectus. It is a subtriangular sclerite between the lateral panel of the pronotum and the tegula. The prepectus is absent in the proctotrupoid families which otherwise in venation resemble chalcids. In chalcids the prepectus is reduced very rarely (in Rotoita; and in some Macromesus, but then the mesothoracic spiracle can be found at the dorso-lateral margin of the mesoscutum In the proctotrupoid groups this spiracle is always situated much lower. The chalcidoid antennae are almost always elbowed between the scapus and the rest (indistinctly so in some Eucharitidae)."

 

"Other chalcidoid characters may be difficult to see. They include longitudinal placoid sensilla on at least some segments of the flagellum, the second abdominal segment, i.e. the one immediately after the propodeum, transformed into the petiole and always differentiated from the rest of the abdomen, which is here called the gaster (= abdomen). The gaster bears one pair of spiracles, on the sixth tergite (eighth abdominal tergite). Another feature is the form of the ovipositor and its components."
