Difflugia rotiferoformis
Difflugia rotiferoformis, from Snegovaya and Alekperov, 2005

Difflugia rotiferoformis  Snegovaya and Alekperov, 2005

Diagnosis: Shell light yellow, elongated, resembling a rotifer in general outlook, with the aboral part narrowed into a small tail; pseudostome oval and bordered by small pieces of quartz. Endoplasm colorless, without inclusions. There are 2 or 3 short lobose pseudopodia. There are several contractile vacuoles.

Dimensions: Length 130-150 µm; width 75-90 µm; tail 15-20 µm; pseudostome diameter 30-35 µm.

Ecology: Freshwater. On the aquatic plants in the small bays of Kurakchay river.

Remarks: According to Snegovaya and Alekperov, 2005, there are several representatives of the Difflugia genus with a “tail”. This species differs from:
1. D. oblonga var. acuminata Ehrenberg 1838 in having smaller shell size and a blunt tail end.
2. D. mamillaris Penard 1902 in shell shape and larger shell size.
3. D. difficilis Thomas 1955 in larger shell size and absence of apertural collar.
