| Comments | Round, Crawford & Mann (1990), p. 684, state: "Synonym of Amphipleura Kützing 1844 (by lectotypification)". Indeed, Cleve 1894 (ref. 000232) chose Frustulia pellucida as the type of genus Amphipleura Kützing 1844 (ref. 000595). By lectotypification of the genus Amphipleura Kütz. 1844, genus Aulacocystis Hassal 1845 became nomenclatural synonym of Amphipleura Kütz. 1844. |

| Comments | Name conserved vs. Scalptrum Corda 1835 (nom. rej. taxonomic synonym) (see ICBN 1956, p. 201, ref. 006916). One species described, G. hippocampus, but Hassall also states: "in the same genus with this species should be placed the Navicula sigma, N. scalprum, and N. curvula of Ehrenberg. ICBN (1994) states that when Gyrosigma is considered a synonym of Pleurosigma, Pleurosigma is conserved against Gyrosigma. |
