Dichadogonyaulax Sarjeant, 1966b, p.153.
EMENDATIONS: Sarjeant, 1975a, p.50; Woollam, 1983, p.193; Benson, 1985, p.152. SYNONYM(S): Taxonomic senior synonym: Ctenidodinium, according to Lentin and Williams (1973, p.46) - however, Sarjeant (1975a, p.50) and Benson (1985, p.152) retained Dichadogonyaulax. Taxonomic junior synonyms: Brotzenia, by implication in Fensome and Sarjeant (1982, p.56), who transferred the "type species" of Brotzenia - Brotzenia cristata - to Dichadogonyaulax; Avellodinium, by implication in Davey (1982b, p.26), who transferred the "type species" of Dichadogonyaulax, Dichadogonyaulax (originally Gonyaulax) culmula, to Avellodinium - however, Lentin and Williams (1985, p.31) retained that species in Dichadogonyaulax and retained Avellodinium. COMMENTS: Although the "type species" was not validly transferred by Sarjeant (1966b, p.153), the generic name Dichadogonyaulax was validly published by that author since it is based on a previously validly published species name (I.C.B.N. Article 37.2). TYPE: Norris, 1965, figs.8-9, as Gonyaulax culmula.
