Platessa lutheri

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Marina Potapova - January 2012
Length Range: 7.4–11 µm
Width Range: 4.4–5.0 µm
Striae in 10 µm: 26–30 on raphe valve, 12-15 on rapheless valve

Description

Valves are elliptic. The raphe valve has a narrow linear axial area and a transversely rectangular central area. The raphe is filiform and straight with slightly expanded external distal and proximal ends. The internal proximal raphe ends are turned to opposite sides, while the internal distal ends have small helictoglossae. Striae are uniseriate and moderately radiate. The rapheless valve has a wide elliptic–lanceolate axial area and short triseriate striae.

Autecology Discussion

So far Platessa kingstonii has been found only in two streams in north–central Pennsylvania. Conductivity in these streams ranged from 19 to 38 μ S cm−1, and pH was 6.0–6.5.
