Originally Pterospermopsis, subsequently (and now) Thalassiphora, thirdly Disphaeria. Taxonomic junior synonyms: Thalassiphora sueroi and Thalassiphora (as Disphaeria) balcanica, both according to Stover and Evitt (1978, p.194) — however, Sütő-Szentai (2000, p.162) retained Thalassiphora (as Spiniferites) balcanica. Pterocystidiopsis (as Thalassiphora) velata and Adnatosphaeridium (as Thalassiphora) patulum, both according to Benedek and Gocht (1981, p.59) — however, Lentin and Williams (1985, p.354) retained Thalassiphora patula and Brinkhuis and Biffi (1993, p.179) retained Pterocystidiopsis (as and now Thalassiphora) velata; Subathua sahnii, according to Lentin and Williams (1985, p.340) — however, Subathua sahnii is now considered to be a taxonomic junior synonym of Adnatosphaeridium (as and now Thalassiphora) patulum; Subathua spinosa, according to Lentin and Williams (1985, p.340) — however, Stover and Williams (1987, p.207) retained Subathua (as Thalassiphora) spinosa (now Thalassiphora simlaensis).
