Obertrumia gracilis
Foissner, 1989
(
Fig. 1G
)
Diagnosis:
Body size 65 × 35 μm in protargol preparations; body ellipsoidal, anterior and posterior body ends rounded; rigid. Macronuclear nodule spherical to elliptical, positioned at midbody with spherical to elliptical micronucleus. Contractile vacuole at midbody, one excretory pore. Cytoplasm colorless. Usually 60 somatic kineties and bipartite nassulid organelles.
Remark:
The genus
Obertrumia
can be distinguished from
Nassula
mainly by the feature of nassulid organelles (bipartite in
Obertrumia
;
Foissner
et al.
, 2002
).
Obertrumia gracilis
has similar morphology to the congener
O. kahli
while the latter species differs from the former by the proportion of the number of bipartite nassulid organelles (
Foissner, 1989
).
Voucher slides:
Two slides including protargolimpregnated specimens have been deposited in the National Institute of Biological Resources in
Korea
(NIBRPR0000 107134, NIBRPR0000107135).
