Longinebela meisterfeldi Heger et Mitchell, 2012

Diagnosis: The shell is acrostome, elongated pyriform, laterally slightly compressed, with wavy lateral margin, brownish in color. Shell composed of small particles likely obtained from preys (i.e. euglyphid testate amoebae). The aperture is oval, surrounded by a very thin collar of organic cement.

Dimensions: length 147-160 µm, breadth 69-85 µm, diameter of aperture 37-42 µm (n=6).

Ecology: Sphagnum mosses in a peatland in Strathcona Park, Vancouver Island and from aquatic mosses at the border of a small stream in Grouse Mountain, British Columbia, Canada.

Remarks: Longinebela meisterfeldi resembles Gibbocarina gracilis, G. gracilis var. stomata Wailes, 1912 and N. penardiana by the shape of its shell. It is distinguished from the above mentioned species by the presence of wavy lateral margins.
