[request]From editor or global species database
Authority Luther (1955) states on p. 155 : "Dalyellia s.str. Gieysztor " which is sometimes wrongfully interpreted as if Gieysztor is the author of the name. This is not the case, Fleming (1822) is the correct authority. Gieysztor (1938) just restricted the name to what it is more or less now. [details]
