Diagnosis.
Body size 110-130 × 30-45 μm in vivo; body shape lanceolate; highly contractile; cytoplasm colorless; extrusomes ventrally scattered, size about 6.0-7.0 × 0.5 μm; about 7-9 warts on dorsal side; 2 or 3 contractile vacuoles located subterminal to ventral side; 1 micronucleus in between 2 macronuclei; 12 or 13 right and 5 or 6 left somatic kineties; 3 perioral kineties; 2 left side furrows present; brackish water habitat.
Distribution.
Korea
and
China
.
Remarks.
Loxophyllum
is a speciose taxon with more than 60 nominal species (
Pan
et al.
, 2013a
). The Korean population of
Loxophyllum chinense
differs from the
type
population only in the habitat salinity (3‰ vs. ca. 20‰) (
Pan
et al.
, 2013a
).
L. chinense
can be distinguished from the most similar congener,
L. perihoplophorum
Buddenbrock, 1920
, in the body length (110-130 μm vs. about 400 μm) and the location of contractile vacuoles (ventral vs. dorsal) (
Kim and Min, 2015
).
Voucher slides.
Two slides of protargol-impregnated specimens were deposited at National Institute of Biological Resources (NIBRPR0000109489, NIBRPR0000109490).
