Rhabdostyla variabilis Dons, 1918

Scyphidia variabilis Dons, 1918 — Kahl, 1935: 671, pl. 128, fig. 32

Rhabdostyla variabilis Álvarez-Campos et al., 2014: 276

Diagnosis: Size about 60–90 µm. Peristomial collar approximately with the same width as the largest part of the body. Prominent peristomial disc. Very short peduncle. Kidney-shaped macronucleus. Found on polychaete tentacles.

Remarks: diagnosis compiled from the works of Kahl (1935) and Álvarez-Campos et al. (2014). In 1935, Kahl recombines this species to the genus Scyphidia , without much justification, and in 2014, Álvarez-Campos et al. (2014) treats this species as belonging to the genus Rhabdostyla . Due to these facts, we consider this species as valid for the genus, but a new look must be given considering new information.
