Bivalvia - Nuculanida - Malletiidae

Taxonomy

Palaeoneilo was named by Hall and Whitfield (1869) [Sepkoski's age data: O Aren-u J Plie-u Sepkoski's reference number: 91].

It was reranked as Yoldia (Palaeoneilo) by Meek (1871).

It was assigned to Yoldia by Meek (1871); to Nuculidae by Isberg (1934); to Nuculanacea by Amler (1992); to Nuculoida by Sepkoski (2002); to Malletiinae by Harrison and Harrison (1975), Pojeta and Gilbert-Tomlinson (1977), Hayami and Kase (1977), Vokes (1980), Fang (2006), Scholz et al. (2008); to Palaeoneilinae by Bouchet et al. (2010); and to Malletiidae by Ros-Franch et al. (2014).
