The status of this genus is anything but clear. Many authors consider it and Pteromalus 

 Swederus to intergrade. In addition there is the problem of the name Colas Curtis, its 

 isogenotypic synonym Metopachia Westwood, and the emended or new names Gnatho Curtis, 

 Colax Curtis, and Metopopachia Dalla Torre. All of these are based on the distinctive European 

 species dispar. All but Metopopachia have priority over Habrocytus Thomson. Graham, 1969 

 (Brit. Mus. (Nat. Hist.) Ent., Bui. Sup. 16: 495) does not think it advisable to use the name Colas 

 for this genus because of the widespread usage of the name Habrocytus. There is also a great 

 possibility that the species-group dispar will eventually be recognized as a distinct genus, in 

 which case the name Colas will be available for it. In the meantime, priority is not recognized. 

 Disregard of priority occurs elsewhere in the Chalcidoidea.
