Apodesmia was described from Germany by Foerster in 1862. It has usually been treated as a synonym of Opius Wesmael, though often as a valid subgenus. It has recently been treated as a valid genus, based almost exclusively on a single character associated with curvature of the occipital carina. A group of New World species reared from stem-galling Tephritidae has this characteristic, but differs in many other features. Morphological differences between Apodesmia s. s. and the members of this New World group are highlighted in support of an hypothesis of convergence in this particular feature.
