Dark, robust and heavily sculptured wasps. Chelonines are distinguished from other Braconids by possession of a gastral carapace formed by the fusion of the first three tergites, together with a complete postpectal carina, and three submarginal cells in the forewing. Around 20 UK species, whiuch are very difficult to distinguish.
