Synedra bacillaris (Grunow) Hustedt

Reported by Lobban et al. (2012). Lobban et al. (2022) renamed that species Grunowago bacillaris (Grunow) Lobban & Ashworth but were unable to establish its presence in Guam, so established a new species, Grunowago pacifica Lobban & Ashworth, for the Guam material.
