Tunariorthis, a New Substitute Name forTunariaBenedetto, 2013 (Brachiopoda, Heterorthidae)

Abstract

The generic name Tunaria was erected by Benedetto (2013) to include the species Orthis berthoisi? var. erratica Davidson, 1869 from England, France and Spain, and the new species Tunaria cocksi from the Late Ordovician San Benito Formation of Bolivia. According to the ICZN (1999) Tunaria Benedetto, 2013 is an illegitimate name because it is a later homonym of the linguloidean brachiopod Tunaria von Hoek, 1912, p. 247 (type Tunaria cochabambina), non Link, 1807, which was renamed as Tunarites by Cooper and Muir-Wood (1951). The name Tunaria was used subsequently by Piran (1957) to designate an acanthosomatid hemipera from Bolivia (type species Tunaria andicola Piran) which also is a junior synonym of the cnidarian Tunaria Link. Therefore, the new name Tunariorthis is proposed to substitute the illigitimate name Tunaria.
