1925 Circophyllia truncata Goldfuss sp. 1826: Felix, pars 28, p. 53 (older synonyms cited therein).

1969 Ghirobocyathus lagaensis n. g., n. sp.: Barta-Calmus, p. 827, pl. 1, figs 12–15.

Dimensions. d (max)=13.5– 28 mm; d (min)= 13–25 mm; d (min)/d (max)=0.85–0.96; s=96 (in corallite diameter of 13 mm and larger); h=up to 22 mm.

Description. Bowl-shaped to turbinate-subpatellate corallum; costosepta arranged in 5 cycles in 6 systems in mature corallites.

Remarks. The specimens assigned to Ghirobocyathus lagaensis by Barta-Calmus (1969) show 96 septa in corallites with diameters ranging between 12 and 20 mm. In the holotype of the species C. truncatum 96 septa are present when the corallum has reached a diameter of around 15 mm. Therefore, the synonymy of the two species is assumed.

Type locality of species. Eocene of France .
