Nomenclatural note
Name and generitype conserved. CDN: "Name conserved vs. Dendrella Bory (nomenclatural synonym) and Diomphala Ehrenberg 1843 (taxonomic synonym) (see ICBN 1956, p. 200, ref. 006916). Introduced as a new genus (pl. 214, fig. 103: Didymosphenia n.g. sibirica) but later in the text seems to be considered a subgenus of Gomphonema: "Das neue Subgenus von Gomphonema ist durch das in beiden Endknoten scharf nach derselben Seite abbiegende Ende der Raphe immer deutlich gekennzeichnet" (this new subgenus of Gomphonema is characterized by the unilaterally curved ends of the raphe). Three species are originally included, D. sibirica (Grun.) M. Schmidt, D. curvirostrum (Temp. & Brun) M. Schmidt, and D. geminata (Lyng.) M. Schmidt, and no type is designated. Didymosphenia is also a nomenclatural synonym of Gomphonema Agardh (nom. rej.)." - (26 January 2017) - M.D. Guiry
