Light and scanning electron microscopical observations are made on two non–raphid pennate species from Lake Baikal, Russia. Based on their morphologies, they are assigned to the genus Ulnaria. Molecular data from rbcL sequences were also generated from cultures of these two taxa. Combined morphological and molecular data suggest one of the species is the same as a species commonly referred to as Synedra acus, a species commonly reported from Lake Baikal and used as a model species for studies on valve silicification and nanotechnology applications. The second species is similar to Ulnaria ulna. Both taxa are important players in the ecology of Lake Baikal. Based on the combined molecular and morphological approach, and comparison of the species with recently designated types for both U. ulna and U. acus, we conclude that the two species are not synonymous with either U. acus or U. ulna, or other known species, and present full descriptions of them as species new to science.
