(Rhodomelaceae, Rhodophyta) from Jeju Island, Korea. Algae 27(4): 259-268.
Notes:
The genus Pterosiphonia is composed of 22 species worldwide and four of these species have been reported in the
North-East Asia. In Korea, P. pennata originally described from the Mediterranean Sea has been previously recorded from
the southern coast as a widespread species. In order to confirm the same species from Korea and Mediterranean, we
observed the morphology of Korean Pterosiphonia specimen and analyzed rbcL sequences for inferring phylogenetic relationships
among similar congeners. Korean entity was recognized as a new species, Pterosiphonia arenosa sp. nov. The
new species is characterized by ecorticate axes with 7-10 pericentral cells, branches formed every two segments, and coalesced
with main axis over 1-1.25 axial segments, and tetrasporangia formed in straight series on determinate branches
of the upper parts of erect axes. A phylogenetic analysis of rbcL sequences demonstrated that P. arenosa was distinct from
P. pennata found in Spain as well as other species. In conclusion, morphological and molecular sequence data indicated
that P. arenosa sp. nov. has been previously misidentified as P. pennata in Korea.
