On the valid name of gudgeon from the Chornaya River (Crimea Peninsula) (Teleostei: Cyprinidae: Gobio)
M. Kottelat & N.G. Bogutskaya
Abstract. Gobio delyamurei Freyhof & Naseka, 2005 and Gobio tauricus Vasilieva, 2005 are subjective synonyms. Gobio delyamurei was published the 29th of November 2005 and takes precedence over G. tauricus published on the 30th of November 2005. Should there be any claim that the names appeared the same day, the precedence is fixed here to G. delyamurei (Art. 24.1-2).
