Diagnosis.
Cell size 30-40 × 28-35 μm in protargol preparations; 9 somatic and 4 preoral ciliary rows with an average of 183; 2 contractile vacuole; kinety 1 consisting of widely spaced dikinetids; adoral membranelle 1 absent; membranelles 2 and 3 right-angled to each other.
Remarks.
Omar and Foissner (2012)
found the uniqueness of the Floridian population within the
Leptopharynx costatus
and suggested its subspecies,
L. costatus gonohymen
.
Leptopharynx costatus gonohymen
can be distinguished from
L. costatus costatus
by the numbers of dikinetids (7-8 vs. 11-15) and monokinetids (1 vs. 0-2) in kinety 1, while the Korean population has 7 dikinetids and 1 monokinetid in kinety 1 (

) (
Omar and Foissner, 2012
).

Deposition.
Two voucher slides with protargol-impregnated specimens are deposited in the National Institute of Biological Resources in
Korea
(NIBRPR0000109452, NIBRPR0000109453).
