Alterasynedra Lange-Bertalot with comments on the typification of Synedra Ehrenberg. In: Lange-Bertalot Festschrift. Studies on diatoms dedicated to Prof. Dr. Dr. h.c.

Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Liu, B., Williams, D.M. & Tan, L. (2017). Three new species of Ulnaria (Bacillariophyta) from the Wuling Mountains Area, China. Phytotaxa 306(4): 241-258, 71 fig.
"Currently there are upwards of 30 species in the genus Ulnaria, with a number yet to be described (Williams pers. comm.) or still identified as species of Fragilaria Lyngbye (1819: 182) (Lange-Bertalot & Ulrich 2014 named some obvious species of Ulnaria as Fragilaria). Ulnaria is distributed worldwide but there are species and species groups that are restricted to just one area." (Liu, William & Tan 2017: 256). - (23 Nov 2017) - M.D. Guiry
