First Report of Two Species of Mantid Shrimps (Stomatopoda: Squilloidea: Squillidae) from Korean Waters

Two species of mantid shrimps were collected from southern part of Korea and identified as Kempella mikado and Squilloides leptosquilla of the Squillidae. The former species is characterized by having a dactylus of the raptorial claw with six teeth, only the fifth thoracic somite with a single spinous lateral process, and the fifth abdominal somite with a pair of black dorsal patches. However, the latter species is characterized by having a dactylus of the raptorial claw with four teeth, and the fifth to seventh thoracic somites each with a single lateral process. Both species are described with figures and photographs. The present records are extensions of their geographical distributions and new records in Korea. Hence, a total of six species of the stomatopods have been recorded in Korea up to date: Oratosquilla oratoria, Faughnia formosae, Taku spinosocarinatus, Chorisquilla spinosissima, Kempella mikado, and Squilloides leptosquilla.
