Rhabdostyla ringens ( Müller 1786)

— Fig. 4 , H’

Vorticella ringens Müller, 1786: 309 , pl. XLIV, fig. 10

Epistylis ringens Fromentel, 1874: 240 , pl. IV, fig. 6

Rhabdostyla ringens Kent, 1881: 666 , pl. XXXIV, fig. 1

Diagnosis: Size about 80µm. Conical and elongated body, apatulabout twice long as wide. Peduncle short and thin, about a third of the body’s length. Pellicle apparently without striations and with a slightly brownish color. Freshwater organisms.

Remarks: diagnosis compiled from the works of Müller (1786) and Kent (1881). According to Müller, there is a doubt whether this species is the same as described by Chevalier, as Chevalier’s Vorticella ringens has no description.
