Observations: Bart Van de Vijver
Length: 11-17µm
Width: 2-3µm

Description:

Valves lanceolate, swollen in the middle with obtusely rounded apices (L 11 17µm, W 2-3µm, 15-18 striae in 10µm). Axial area rather broad, linear to lanceolate. Central area forming a rectangular fascia. Raphe filiform, slightly curved. Central endings weakly deflected with small but distinct central pores. Terminal fissures hooked. Transapical striae parallel to weakly radiate, parallel or convergent towards the poles.

Morphology: Naviculoid

Notes:

Crique de Noel, Ile de la Possession, Crozet Archipelago, Sample BA160 (coll. date 28/01/2002).Found regularly on cliffs and in small caves bordering the coastline. The influence of sea-spray is quite likely.So far only found on Ile de la Possession.The combination of features (especially the interruption of the striae on the valve face/mantle margin) justifies the place of this new taxon within the genus Chamaepinnularia. It closely resembles C. soehrensis var. muscicola but can easily be distinguished by the more irregular valve outline.
