Part of a field survey to assess the extent of damage by termite (Reticulitermes speratus kyushuensis Morimoto), termite samples were collected from various locations of Korea from 2009 to 2011. During the study period, we firstly discovered Reticulitermes species on Jeju island, and partial sequences of mitochondrial COII gene, which is proved useful to study phylogenetic relationships of termites were investigated. Also, morphological characteristics of the collected samples were compared with previous reports. According to the result of taxonomic study and comparative sequence analysis, it was identified as Reticulitermes speratus kyushuensis Morimoto, and this is first report of R. s. kyushuensis from Jeju island in Korea which can be used as estimation of population structure and tool of control strategy.
