General Environment
This is a marine species.
Description
Frustules narrowly rectangular and slightly curved in
girdle view. Valves lanceolate with sub-acute apices,
37–43 µm long and 6–7 µm wide. Two apically elongated
chloroplasts lying against each side of the girdle. Raphe
straight and central without a well-defined axial area. Cell
wall extremely delicate, longitudinal and transapical striation
not visible in light microscopy. Transapical striation
34–36 in 10 µm, longitudinal striation 42 in 10 µm.
External raphe endings straight and slightly expanded at
the centre of the valve, strongly deflected to one side at the
poles. Internal raphe fissures open to one side of the raphe
sternum except at the centre and near the apices. An
accessory rib extends besides the raphe sternum throughout
most of the valve, on the primary side. Internally the areolae are quadrate, arranged in
regular rows. Externally, the valve appears covered by
longitudinal strips, separated by slits parallel to the raphe
and merging with a peripheral slit near the apices.
