Type species: Gracilaria scalariella Zeller, 1850. Stettiner entomologische Zeitung 11: 160. By original designation. The type species was established in combination with the generic name Gracilaria, at that time an incorrect subsequent spelling of Gracillaria Haworth, 1828. Gracilaria was not established as an emendation until 1907, by Walsignahm in Sharp (1907d) (Nye & Fletcher 1991: 92).
