Name derivation:
Classification:
Pseudotriatella S.Sato, D.G. Mann and L.K.Medlin 2008; the holotype species P. oceanic is the only species description, and it is currently accepted taxonomically (Guiry and Guiry 2013). Order Striatellales; Family Striatellaceae
Morphology:
Colony of araphe pinnate diatoms, cells attached with mucilage pads at valve poles usually forming a zig-zag pattern (cf. Tabellaria), occasionally unicell, observed almost exclusively in girdle view due to several girdle bands that broaden the girdle into a rectangular outline. Each cell has multiple discoid chloroplasts
Similar genera:
Striatella has a single reticulate chloroplast.
Habitat:
Marine plankton, widespread.
