From editor or global species database
Authority Braun (1833:106) refers to Münster. As Braun's work is no more than a list of specimens in the collection in Bayreuth, and by lack of acceptable description, it is here considered a nomen nudum under Braun authority. The species was later validly described by Münster in 1840. [details]
