Rhabdostyla fromentellii ( Kent 1881)

— Fig. 2 , Q

Scyphidia fromentellii Kent, 1881 –1882: 659, pl. XXXIII, fig. 53

[ Rhabdostyla] (Rhabdostyla ) fromentelii Kent, 1881 –1882— Kahl, 1935: 677, pl. 129, fig. 27

Diagnosis: Size about 80µm. Elongated-claved shape, truncated anteriorly and with the posterior portion without striation when contracted. Peduncle with longitudinal striations. Apparently with 2 or 3 contractile vacuoles. Found in freshwater environments.

Remarks: diagnosis compiled from the works of Kent (1881) and Kahl (1935). According to Kent (1881) De Fromentel proposed a synonym of this species with Scyphidia dubia , which was refuted by Kent due to the existence of a distinct peduncle and three contractile vacuoles.
