Diagnosis.
Cell size 105-125 × 20-30 μm in protargol preparations, slenderly elliptical body shaped, flexible; adoral zone about 23% of body length, 22-25 adoral membranelles; contractile vacuole at slightly ahead of mid-body near left cell margin; 2 macronuclear nodules with 2 micronuclei; 3 frontal cirri1 buccal cirrus; 3 cirri left of anterior end of amphisiellid median cirral row; 20-23 cirri in amphisiellid median cirral row; 4 transverse cirri; 1 left (42-50 cirri) and 1 right (36-42 cirri) marginal cirral row; 3 dorsal kineties; caudal cirri lacking.
Remarks.
Berger (2008)
found a different number of cirri between the European and the Namibian populations, and suggested that
Uroleptoides binucleatus
should be divided into two subspecies
U. binucleatus binucleatus
(European population) and
U. binucleatus multicirratus
(Namibian population). The morphology of the Korean population follows that of
U. binucleatus binucleatus
, and mainly differs from
U. binucleatus multicirratus
by the following two features: numbers of adoral membranelles (22-25 vs. more than 38) and cirri in amphisiellid median cirral row (20-23 vs. more than 50).

Photomicrographs of
Uroleptoides magnigranulosus
from life (A) and after protargol impregnation (B-D). (A) Arrows indicates cortical granules on ventral surface. (B, C) ventral views. (D) Dorsal view. Scale bars = 50 μm.
Deposition.
One voucher slide with protargol-impregnated specimens is deposited in the National Institute of Biological Resources in
Korea
(NIBRPR0000109449).
