Abstract:
DNA barcoding is becoming a widely applied tool to accurately discriminate red algae. We tested the effectiveness of DNA
barcoding for identification and discovery of Champia species in Korea and clarified the phylogenetic relationships using
the plastid rbcL gene. As results, we described four species of Champia such as C. inkyua sp. nov., C. recta Noda, C. bifida
Okamura, and C. expansa Yendo. A new species, C. inkyua, is characterized by entangled thallus, terete and irregular
branches, hooked apices, and longitudinal filaments running throughout the frond periphery only. Longitudinal filaments
were composed of a complete cell with two half cells between diaphragms in the cavity. C. recta and C. bifida were
reinstated with previously used names of C. parvula and C. compressa, respectively. C. recta is the first recorded species
from Korea and is characterized by an erect thallus, terete and irregular branches, and straight apices. C. bifida is characterized
by compressed thallus, pinnate or alternate branches, and bifid apices. C. expansa is characterized by flabellate
thallus and dichotomous branches. Molecular analyses of COI and rbcL genes revealed sufficient sequence divergence to
warrant species recognition in the genus Champia.
