Gomphonema sp. ( G. cf. pseudacuminatum ) ( Figs 76–87 )

Valves of this group of individuals appear slightly more narrow and with less pronounced undulations that in the new species above described, but the dimensions of this group of specimens is similar to our new species. Length: 26.0– 43.3 μm, breadth: 6.7–8.0 μm, striae: 11–12 in 10 μm. Observations on additional specimens will help to determine if these are part of a separate taxon or reflect a greater diversity in shape than we currently recognize.
