New Record of a Sea Urchin Echinometra mathaei (Echinoidea: Camarodonta: Echinometridae) from Jeju Island, Korea and Its Molecular Analysis

다국어 초록 (Multilingual Abstract)

Echinoids were collected at depths of 5-10 m in Munseom, Jeju Island by SCUBA diving on November 23,2008 and September 15, 2009. Two specimens were identified as Echinometra mathaei (Blainville, 1825)based on morphological characteristics and molecular analyses of mitochondrial cytochrome c oxidase subunit I partial sequences. Echinometra mathaei collected from Korea was redescribed with photographs and was compared with other species from GenBank based on molecular data. Phylogenetic analyses showed that no significant differences were between base sequences of E. mathaei from Korea and that from GenBank. To date, 13 echinoids including this species have been reported from Jeju Island, and 32 echinoids have been recorded in Korea.
