discussion
Comments: Differing from Pseudictyota dubia (Brightwell) P. A. Sims & D. M. Williams (Navarro & Lobban 2009, figs 21 – 24), which has six angles, three with ocelli and three with rimoportulae; and from P. reticulata (Roper) P. A. Sims & D. M. Williams (Lobban et al. 2012, pl. 3, figs 3, 4, as Triceratium dictyotum P. A. Sims & R. Ross), which is broadly lanceolate with two angles each with both an ocellus and a rimoportula.
