| Comments | Originally described (and validly pulished) as a subgenus of Synedra: Synedra subgenus Synedrosphenia H. Peragallo in H. & M. Peragallo 1900 (ref. 000733), p. 308, 312. Three species were included, Synedra cuneata Grun., S. clavata Grev. and S. dubia Grun and no type was designated. Although Azpeitia 1911, p. 220 (ref. 000114) introduces the name as "El genero ó subgenero Synedrosphenia" (the genus or subgenus Synedrosphenia), he treats it as a genus when describing his new species Synedrosphenia giennensis. Although S. giennensis Azpeitia is the only species formed as binomial with Synedrosphenia in Azpeitia 1911, Azpeitia, in his treatment of Synedrosphenia also clearly included the 3 species that constituted Peragallo's subgenus (but did not make transfers to genus Synedrosphenia). No type was designated by Azpeitia. The generic name cannot be attributed directly to Azpeitia because he did not provide a generic description. The authorship of Synedrosphenia is therefore "(H. Peragallo in H. Perag. & M. Perag.) Azpeitia, and the type has to be chosen among the species originally included in the subgenus by Peragallo. The choice of S. giennensis as the type species by Round, Crawford & Mann (1990) p. 444 and 704 is therefore untenable. |
