Leptopharynx costatus costatus
Mermod, 1914
(
Fig. 1F
)
Diagnosis:
Body size 25 × 15 μm in protargol preparations; body broadly ellipsoidal with blunt end of ventral side; rigid. Macronuclear nodule spherical to elliptical, positioned at midbody. Contractile vacuole at 2/3 of body length. Cytoplasm colorless. Usually 10 somatic and 3 preoral kineties. Extrusomes fusiform.
Remark:
Because of the small size (ca. 25 μm in length), it could be easily neglected.
Omar and Foissner (2012a)
reported a new subspecies
L. costatus gonohymen
, which can be distinguished from
L. costatus costatus
by the shape of adoral membranelles.
Voucher slides:
Two slides including protargolimpregnated specimens have been deposited in the National Institute of Biological Resources in
Korea
(NIBRPR0000 107130, NIBRPR0000107131).
