Descriptions of Protospathidium serpens (Kahl, 1930) and P-fraterculum n. sp (Ciliophora, Haptoria), two species based on different resting cyst morphology
Protospathidium serpens (Kahl, 1930) is frequent in semiterrestrial and terrestrial habitats worldwide. Conventionally, all populations are considered as conspecific because they have very similar overall morphologies and morphometrics. We studied in detail not only the morphology of the vegetative...
