Samples: Moen1_ Padina

Dimensions: 36.7 μm long, 8.0 μm wide; dorsal striae 15 in 10 μm, ventral striae 13 in 10 μm.

Diagnostics: Central raphe endings fairly far from the ventral margin, a wide gap between the central striae, and the ventral striae consisting of two elongate areolae.

Comments: Our valves were slightly smaller than the range in Wachnicka & Gaiser (2007), and the stria density was slightly higher.
