Ceraphronoidea is a small Hymenoptera
n superfamily that includes only two families, and a total of some 800 species, though a great many species are still undescribed. It is a poorly-known group as a whole, and most are believed to be parasitoid
or hyperparasitoid
s.
The two families are unified by several characters, the most visible of which is that the wing venation is greatly reduced in a very specific and unique way; the costal and radial veins have fused so there is no costal cell, there is a short break at the stigma, and the only vein in the wing membrane itself is the radial sector, which is short and curved. arising from the stigma.
