Luffisphaera longihastis Vørs, 1993

Diagnosis: Spine scales consist of a cylindrical base supporting a cone-shaped part, which gradually tapers to a narrow tip. This tip is mounted by a long, thin whip-like spine. The base and the cone are each composed of a proximal lattice with criss-cross pattern and a distal lattice with longitudinal rods only. Cell spherical or almost so, 34.2 µm in diameter (dried cells), covered with a dense layer of scales. Most of these are base scales, but more than 20 or so are furnished with spines. Spine scales consist of a cylindrical base supporting a cone-shaped part, which gradually tapers to a narrow tip. This tip is mounted by a long, thin whip-like spine. The base and the cone are both composed of two differently patterned parts: a proximal lattice with criss-cross pattern and a distal lattice with longitudinal rods only. The top of the cone and the spine consist of smooth, homogeneous, non-lattice material. The spine scales are 2.54 µm in total length.
