Examined species: Celetaia persculpta (Sarasin & Sarasin, 1898)

(Figs 4A, 5A, 7A).

Remarks: Apart from Torotaia, Celetaia can be distinguished from other genera with a concentric inverted-comma-shaped operculum by the following combination of characters: a blunt opercular apex; a large, smooth and shiny nuclear region, sometimes surrounded by concentric veins; and a thin marginal region.
