Previously referred to as A. atrovirens (Pope 1977), but this species does not occur in Britain (Cox 2000); therefore, British specimens of A. atrovirens are likely to be A. atratula. Some continental European workers have synonimised A. atratula with A. euphorbiae but in Britain these are considered separate species.
