Nivaliella plana
Foissner, 1980
(
Fig. 1B
)
Diagnosis:
Body size 12 × 6 μm in protargol preparations; body reniform to oblong. Macronuclear nodule spherical to elliptical, positioned at posterior halfbody. Contractile vacuole at posterior body end. Cytoplasm colorless. Somatic kineties composed of dikinetid; ciliatures strongly reduced. Feeding tube distinct, positioned at anterior body end. Paroral membrane semicircular.
Remark:
It was the smallest species (ca. 12 μm in length) of this report and cooccurred with
G. acuta
belonging to the same family. Based on the cooccurrence of the two species from a single moss sample only, it is assum ed that their ecological niche is not broad and
Foissner (1993)
mentioned that
G. acuta
prefers acidic substrates.
Voucher slides:
Two slides including protargolimpregnated specimens have been deposited in the National Institute of Biological Resources in
Korea
(NIBRPR0000 107138, NIBRPR0000107139).
