Calothrix sinica Molinari & Guiry , nom. nov.

Replaced name: Calothrix compacta C.-C.Jao, Sinensia 10: 223, 1940 (Cyanobacteria, Calothricaceae), nom. illeg., non Calothrix compacta (Bornet & Flahault) Hansgirg (1891: 126) , nec Calothrix compacta (Bornet & Flahault) Margalef (1953: 234) , isonym, Rivulariaceae .

Notes: The species is renamed for China, the country in which it was originally found. The name proposed by Margalef (1953) is an isonym with no nomenclatural standing (Art. 6.3, note 2,) of that of Hansgirg (1891), since both are based on Dichothrix compacta Bornet & Flahault (1886: 378) , a genus currently considered to belong to the Rivulariaceae
