PROTOPERIDINIUM subgenus PROTOPERIDINIUM section SELENOPEMPHIX (Benedek, 1972, p.47) Harland, 1982, p.396. Emendations: Bujak in Bujak et al., 1980, p.82; Head, 1993, p.32, both as Selenopemphix. Combination not validly published: basionym not fully referenced. NOW Selenopemphix. Originally (and now) Selenopemphix, subsequently Protoperidinium subgenus Protoperidinium section Selenopemphix (name not validly published). Taxonomic junior synonyms: Omanodinium, according to Bradford and Wall (1984, p.49) and Head (1993, p.32); Multispinula, according to Matsuoka (1985a, p.51) and Head (1993, p.31-32).
