Longinebela golemanskyi (Todorov, 2010) Kosakyan, Lahr, Mulot, Meisterfeld, Mitchell et Lara, 2016

Diagnosis: Shell piriform to elongated-piriform in broad view, with a distinct short neck aproximately 1/4th of the body length, and a rounded aboral region nearly uncompressed laterally. No lateral pores. Shell colourless, composed of characteristic voluminous, globular, or rarely elongated, rounded, and hollow siliceous plates, with an average diameter of ca. 10–15 μm. Occasionally small diatom frustules scattered sparsely over the surface are incorporated among the plates. Large gaps are usually present between plates, interspersed with well visible, small beads of organic cement. Pseudostome roughly circular to ovoid in frontal view, linear in broad view, and bordered by a thin organic rim.

Dimensions: According to Todorov (2010): Shell length 209.1 ± 6.94 μm; width 118.2 ± 5.71 μm; depth 94.8 ± 3.28 μm, n = 24.

Ecology: Sphagnum mosses (high moisture, high organic matter content, pH = 4.9–5.6).

Geographical distribution: Bulgaria.
