One known species:

 

Wailesella eboracencis (Wailes & Penard, 1911)

 

Diagnosis: shell ovate, brown, reddish-brown or yellow-brown, chitinoid; aperture circular, subterminal; pseudopodia conical; nucleus vesicular, spherical.

 

Dimensions: 20-28 µm long. My measurements 22-69 µm, from several locations in The Netherlands and Austria.

 

Ecology: Sphagnum, mosses and peatbogs. Rare, never abundant.

 

Remarks: the shell strongly resembles a Trinema shell, but the color makes a quick distinction possible.
