Original description The subgenus name was first mentioned by Sayn (1932), but it is not available from that work, since Sayn did not give a type species. Kollmann (1967, p. 215), who actually realized that Sayn's name was formally unavailable but still retained the name as described by Sayn, provided a description and a type species and made the name available.
