Description:
Valves cylindrical with a domed face (Diameter 10-18µm, Mantle height 9 10µm). Valve mantle wall thickened. No sulcus edge and gorge visible. The center of the valve discus is composed of a large, irregularly delimited hyaline zone, surrounded by an area of small striae (only resolvable in SEM).

Notes:
Fairly common in several soil samples, especially those with higher nutrient and salinity input (close to the sea or marine animal colonies).Taxon described from New Caledonia (Manguin 1952). So far also found on Ile Amsterdam and Ile Saint Paul (Van de Vijver, personal observation).The dimensions of the Crozet populations are always larger than the valves described from New Caledonia (Kociolek & de Reviers 1996). Nevertheless, the presence of the hyaline discus may justify the identification as M. guillauminii.
