Family PLEUROTOMARIIDAE Swainson, 1840

concava , Pleurotomaria – Deshayes, 1832-DescrCoqFoss: 246-247, 18, pl. 32, figs 1-3; 1863-DescrCoqFoss: 919. — Type localities: Mouchy-le-Châtel & Chaumont-en-Vexin. — Type age: Eocene (Lutetian). — Type material: UCBL-EM 33432, lectotype (P.-H. Fischer 1958) & 33433 (paralectotype) from Chaumont-en-Vexin; UCBL-EM 33429-33431 (3 paralectotypes) from Mouchy-le-Châtel. — Type species (M) of Chelotia Bayle, 1885 . Preoccupies Pleurotomaria concava Hall, 1865 , which was renamed Pleurotomaria tenuimarginata Hall, 1877 , and Pleurotomaria concava Martin, 1860 , which was renamed Pleurotomaria burgundensis Cossmann, 1899 . — Current status: Chelotia concava (Deshayes, 1832) ( Le Renard & Pacaud 1995: 87; Pacaud 2008: 42; Berezovsky & Pacaud 2019: 595, pl. 7, fig. 2-3).

conoidea , Pleurotomaria – Deshayes, 1831b: 181-182, 260, pl. 4, fig. 4. — Type localities: Bayeux, Meuse & England. — Type age: Jurassic (Bajocian). — Type material: UCBL-EM 32099, syntype from Bayeux. — Current status: synonym of Pyrgotrochus elongatus (J. Sowerby, 1818) [ Trochus ] ( Kollmann 1997: 179-180, pl. 35, figs 3-4).

sulcata , Pleurotomaria –Deshayes, 1839-RegAnim: pl. 42, fig. 8. — Type locality: none given. — Type age: not stated. Listed by Sherborn (1931: 6306) as a Deshayes species, this was merely a transfer of Trochus sulcatus J. Sowerby, 1818 , to Pleurotomaria . Indeed, he had already explicitly made this transfer in 1832-EncyMeth: 791. However, Sowerby’s original combination was a junior homonym three times over, non [Lightfoot], 1786, nec Lamarck, 1804, nec Brocchi, 1814. Lamarck’s species was renamed Jujubinus helenae Pacaud, 2017 , but we are unaware of a renaming of the other two junior primary homonyms.
