Family THRACIIDAE Stolizcka, 1870 [1839]

Osteodesmatidae Couthouy, 1839 ( Couthouy 1839: 129), ex Deshayes ms, was based on Osteodesma Blainville, 1827 , ex Deshayes ms. — Type species (SD Dall, 1903): Anatina myalis Lamarck, 1818 , a synonym of Thracia pubescens (Pulteney, 1799) [ Mya ]. The latter is also the type species (M) of Thracia Blainville, 1824 (two species were originally listed but one was a nomen nudum in 1824). Couthouy attributed the family name to Deshayes, who had listed it as a vernacular, “Ostéodesmes” (Deshayes, 1832-EncyMeth: table facing p. 553). — Current status: synonym of Thraciidae Stoliczka, 1870 , which is in prevailing usage and is conserved under ICZN Code Art. 40.2, with the precedence of 1839.

brevis , Thracia –Deshayes, 1846- Algér: 297, pl. 81, figs 4-6. — Type locality: Oran, Algeria. — Type age: Recent. — Current status: synonym of Thracia distorta (Montagu, 1803) [ Mya ] ( Huber 2015: chapter 5 on CD).

corbuliformis , Thracia –Deshayes, 1824-DictClass: pl. [76], fig. 4-4a; 1830-DictClass16: 236; 1831-DictClass17: 117; 1832-EncyMeth: 1039; 1835-HistNatAnim2: 83; 1839-TraitElem: 6, pl. 9, figs 1-3; 1839-HistNatAnim3: 530, all but the 1824 plate as T. corbuloides . — Type locality: Mediterranean. — Type age: Recent. The name for this species has a complex history. It appeared as a nomen nudum – Thracia corbuloidea – under Thracia in Blainville’s (1824: 347) article on the Mollusques in the Dictionnaire des sciences naturelles. It then appeared with the same spelling the next year, also as a nomen nudum, in the text of Blainville’s Manuel de malacologie et de conchyliologie (1825: 565), referring to figures in the Manuel ’s as-yet unpublished pl. 76, fig. 6. It was previously thought to have become available when this and the other plates were published in 1827. (It would have not mattered that the plate caption was only a vernacular because it referenced the manuscript scientific name in the earlier text.) However, it is now known that this species first appeared in the caption to a plate by Deshayes published in September 1824, with the spelling Thracia corbuliformis , which he later said was an error. However, this original spelling has to prevail (ICZN Code Art. 32). — Current status: this species, native to the Mediterranean, should therefore be known as Thracia corbuliformis Deshayes, 1824 . This species is discussed, as T. corbuloidea Blainville , in Monegatti & Raffi (2001: 190) and Huber (2010a: 500), and as T. corbuloides in Cossignani & Ardovini (2011: 59, 490). A similar but probably new species occurs in west Africa ( Cosel & Gofas 2019: 1020-1021).

Thracia ludovica Deshayes, 1857 ( Glibert & Van de Poel 1966a: 6). — Current status: Cyathodonta ludovica (Deshayes, 1857) ( Le Renard & Pacaud 1995: 68; Pacaud 2008: 85).

tellinoides , Thracia – Deshayes, 1850-TraitElem: 242. Replacement name for Corymya lata Agassiz, 1845 ( Agassiz 1845: 271, 286, pl. 34, figs 1-3), non Sanguinolaria lata Goldfuss, 1837 , both of which Deshayes placed in Thracia . — Type locality: Neuchâtel, Switzerland. — Type age: Cretaceous. — Current status: taxon inquirendum.
