Taxonomic remark The genus name Orthopoma was established without any included species, and it appears that none was ever subsequently included. The genus was diagnosed based on an operculum, which Y. Kano & H. Fukumori have identified as a broken operculum of Septaria clypeolum (Récluz, 1843). [details]
