new species of Ophiuroidea, Ophiacantha
scissionis sp. nov., is described. It was collected from Munseom
Island, Jeju-do, South Korea at a depth of 28–36 m, by SCUBA diving. Ophiacantha scissionis
has unique and distinct morphological characteristics: small disk,
densely covered by small trifid spines, radial shields completely
concealed by disk spines, six arms with four arm spines proximally,
fissiparous. In addition, this species is clearly distinguished from
other species of Ophiacantha
by mitochondrial COI.
This species is usually hexamerous and reproduces asexually by
fissiparity. It is the first report of fissiparous reproduction in the
Key words: Taxonomy, Phylogeny, Brittle stars,
Ophiacanthidae, Mitochondrial COI.
