García-Alcalde (1972) proposed the new genus Xana (type species Xana bubo García-Alcalde, 1972) for a terebratulid brachiopod included in the superfamily Stringocephalacea from the Lower Devonian of the Cantabrian Mountains (Northwestern Spain). In an email message sent on April 3, 2018, the entomologist Dr. Eduardo I. Faundez, from the Patagonia Institute, Magallanes University, Chile, warned the author that Xana was a name previously used by Kurdjumov (1917) for a hymenopteran genus. Xana García-Alcalde, 1972 would be so a later homonym of Xana Kurdjumov, 1917. In accordance with articles 52.3, 52.4, 53.2, 60.3 of the International Code of Zoological Nomenclature (ICZN) (2000), it is proposed here to replace the invalid name with the new name Xanastur. This name refers to the original substituted name (xana, a legendary river and forest nymph) and to the typical region inhabited by the xanas (Asturias, Northwestern Spain). The type species would be Xanastur bubo (García-Alcalde, 1972). Incidentally, Diaz Cosín et al. (1989) also proposed a new genus Xana, with the same García-Alcalde’s derivation nominis, for Xana omodeoi n. sp., an Asturian Annelida Oligochaeta. But when noticing that Xana was already used by Kurdjumov, Marchán et al. (2018) proposed to substitute the junior homonym for Xanina (meaning “small xana” a diminutive common in the Asturian region), with Xanina omodeoi (Díaz Cosín et al., 1989) as the type species.

Key words: Xanastur, terebratulid brachiopod, Lower Devonian, Cantabrian Mountains, Spain.
