Pinnularia subcatenaborealis sp. nov. (Bacillariophyta) a new chain-forming diatom species from King George Island (Maritime Antarctica)
Abstract: During a survey conducted on the freshwater diatom flora of small shallow pools on the Ecology Glacier forefield (King George Island, Maritime Antarctic Region), an unknown spine-bearing chain-forming Pinnularia species, belonging to the Pinnularia borealis species complex, was found.
