Family CARDILIIDAE P. Fischer, 1887

Cardilia – Deshayes, 1835-HistNatAnim2: 448-450; 1839-HistNatAnim3: 642-642. — Type species (OD): Isocardia semisulcata Lamarck, 1819 . 1850-TraitElem: 250-255. Signorelli & Raven (2018) indicated the type species was designated later (SD Deshayes, 1844), but in his 1835 text Deshayes said, “La coquille que nous a communiquée M. De Haan est la même que celle nommée Isocardia semisulcata par Lamarck. Nous croyons qu’elle doit servir de type à un genre nouveau, pour lequel nous proposons le nom de cardilie Cardilia , …” Cardillia Lycett, 1848, is a incorrect subsequent spelling. — Current status: valid type genus of the Cardiliidae ( Nevesskaja et al. 2013: 417, fig. 152-10).

Hemicyclonosta – Deshayes in Michelin, 1825: pl. figs 8-9. — Type species (M): Hemicyclonosta michelini Deshayes in Michelin, 1825. France. — Type age: Eocene (Bartonian). Spelled Hemicyclodonta Deshayes, 1839 -TraitElem2(1): 251, in synonymy of Cardilia Deshayes, 1835 . — Current status: synonym of Cardilia Deshayes, 1835 , under ICZN Code Art. 23.9. Hemicyclostera Bronn, 1838 , and Hemicycloster Paetel, 1875 , are other incorrect subsequent spellings.

Hemicyclodonta – Deshayes, 1839-TraitElem2(1): 251. See above.

inermis , Cardilia – Deshayes, 1844d: 1-8 [covering genus], esp. p. 6, pl. 100. — Type locality: Sumatra. — Type age: Recent. — Type material: not located. — Current status: Cardilia inermis Deshayes, 1844 ( Huber 2010a: 762; Signorelli & Raven 2018: 133, 135-136, figs 3.1-3, 4.3-4).

martini , Cardilia – Deshayes, 1844d: 7-8, pl. 101. — Type locality: Malacca. — Type age: Recent. — Type material: not located. — Current status: Cardilia martini Deshayes, 1844 ( Signorelli & Raven 2018: 135, 136, figs 3.4-5, 4.5-13).

michelini , Hemicyclonosta – Deshayes in Michelin, 1825: pl. figs 8-9; 1835-HistNatAnim2: 450; 1839-HistNatAnim3: 642, the latter two as Cardilia ; 1839-TraitElem1(2): 251, as “ Hemicyclodonta ”; 1857-DescrCoqFoss: 296, 17, pl. 17, figs 10-14, as Cardilia . — Type locality: La Chapelle-en-Serval. — Type age: Eocene (Bartonian). MNHN.F.A09474, syntype. Of this species, Deshayes (1857-DescrCoqFoss: 296) wrote “There are few species as interesting as this one; its rarity, joined to the strangeness of its characters, makes it one of the most valuable in the Paris basin. The first specimen which we studied belonged to M. Michelin; it was for a long time the only one known in the collections”. — Current status: Cardilia michelini (Deshayes in Michelin, 1825) ( Signorelli & Raven 2018: 6, 8, figs 5.15-16).

michellotii, Cardilia ; see next entry.

michelottii , Cardilia – Deshayes, 1844d: 8 [not figured]. — Type locality: Asti, Piedmont, Italy. — Type age: Pliocene; Michelotti. — Type material: not located. Deshayes originally misspelled this name as C. “ michellotii ”, which can be corrected because he indicated that it came from Mr. Michelotti (ICZN Code Art. 32.5). — Current status: the Pliocene Cardilia michelottii Deshayes, 1844 ( Monegatti & Raffi 2001: 186; Signorelli & Raven 2018: 138; Pimentel et al. 2019).
