Michelcostea, a new diatom genus (Bacillariophyta) from the sub-Antarctic Region

Abstract: The genus Michelcostea gen. nov. is described as a new genus based on light and scanning electron microscopy observations made on valves formerly identified under the name of Navicula bryophiloides var. linearis, a taxon invalidly described by Maillard from Iles Kerguelen. The new genus is...

The new genus is characterized in having a deep mantle, uniseriate to biseriate striae, located in deep grooves, interrupted at the valve face/mantle junction by a hyaline zone, composed of small, rounded areolae, occluded externally by clearly perforated hymenes, a curved raphe with unilaterally deflected external distal raphe endings and straight indistinct internal proximal raphe endings. Michelcostea lecohuiana sp. nov. is described as its typus generis. The new genus is compared to similar genera. Notes on its ecology are added.
