    <i>Brevilinea pocosinensis</i> Siver, Hamilton &amp; Morales gen. et sp. nov., a new diatom (Bacillariophyceae) genus from North Carolina, USA
    (Wiley, 2008) Peter A. Siver; Paul B. Hamilton; Eduardo A. Morales
    SUMMARY A new diatom genus, Brevilinea gen. nov., is described from an acidic freshwater lake situated on the Atlantic Coastal Plain of North Carolina, USA. The type for the genus, Brevilinea pocosinensis sp. nov., differs from other diatoms by the presence of a unique and reduced raphe that is restricted to the central portion of the valve. The new taxon has large and distinctive areolae that also serve to separate it from existing genera. The taxonomic placement of the new organism relative to other diatoms possessing a reduced raphe is discussed. Although Brevilinea may eventually be placed into a new family, given the current dynamic state of diatom systematics, it is premature to do so at this time.
