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."
