Editors' Notes
Haeckel listed Stichopilium macropterum under the subgeneric name Stichopilidium, but did not include the subgeneric name in the species name.

Haeckel arbitrarily introduces the name Rholpalocanium varietas for an unnamed species in Bury, 1862, referred to herein as Rhopalocanium sp. Bury, 1862, pl.17, fig.7 [RRHOA3010].[comment from RadWorld database]
