Genus Rhabdostyla Kent, 1881

Rhabdostyla congregata Zacharias, 1903

Report as epibiont on rotifers: This species was found as epibiont on Polyarthra sp., Keratella quadrata, Keratella cochlearis, and Brachionus calyciflorus from a pond in Germany (Zacharias 1903; Schödel 2018).

Remarks: The species was also rarely found on the cladoceran Bosmina longirostris from the same locality (Zacharias 1903). It is Schödel’s (2018) opinion that the species is possibly identical to Epistylis pygmaeum .

Rhabdostyla sp. (in Regali-Seleghim & Godinho 2004)

Report as epibiont on rotifers: The species was found on rotifers Filinia longiseta, Polyarthra sp., Keratella sp. and Brachionus sp. (Regali-Seleghim & Godinho 2004).

Remarks: Among the infested rotifers, F.longiseta was the most frequently infested one, followed by Polyarthra sp., Brachionus sp. and Keratella sp. (Regali-Seleghim & Godinho 2004). This species was also found on other groups of hosts—cladocerans and copepods (Regali-Seleghim & Godinho 2004).
