  • Cleantioides rotundata (Kussakin, 1982) is reported for the first time in South Korea. Specimens of C. rotundata were collected with a small hand net from the intertidal zone of Opo-ri, Yeongdeok-gun in South Korea. This species makes tubes using seagrass debris at our sampling location and distinguished by the following characteristics: pleotelson long, length almost 1.6 times as long as width; dorsum of distal one third with deeply bilobed depression on plane. In this paper, we provide descriptions of diagnostic characteristics and illustrations of morphology of C. rotundata. Additionally, a key to the Korean species of the genus Cleantioides is provided and the partial sequences of the mitochondrial cytochrome c oxidase subunit 1 (CO1) are provided as molecular characteristics.

  • Two marine isopods, Elaphognathia sugashimaensis (Nunomura, 1981) and Metacirolana shijikiensis Nunomura, 2008, have been reported for the first time in South Korea. Specimens of E. sugashimaensis and M. shijikiensis were collected using light traps from Yeongdeok-gun and Gageo-do Island in South Korea, respectively. The genera Elaphognathia Monod, 1926 and Metacirolana Kussakin, 1979 are new to South Korea. In this paper, we provide descriptions of diagnostic characteristics and illustrations of their morphologies. Additionally, the partial sequences of mitochondrial cytochrome c oxidase subunit 1 (CO1) of two species are provided as molecular characteristics.

  • Cleantioides planicauda (Benedict, 1899) has previously been recorded in China and Japan. In the present study, to our knowledge, we report for the first time the occurrence of this species in South Korea. Here, we provide detailed descriptions and illustrations of the diagnostic characteristics of C. planicauda. Further, for the first time, we determined the partial sequence of mitochondrial cytochrome c oxidase subunit 1 (CO1) gene of C. planicauda for molecular characteristic. Additionally, we provide a key to the Korean species and distribution of the genus Cleantioides. As a result of this study, four species of the genus Cleantioides, including C. planicauda, have now been recorded in South Korea.

  • Two species of the genus Burmoniscus Collinge, 1914 (Philosciidae), B. philippinensis and B palawanensis from Palawan Island, the Philippines are described as new. In the family Philosciidae, only a single species, Pseudo-typhloscia alba (Dollfus, 1898), has been recorded from the Philippines. Two species of the genus Burmoniscus Collinge, 1914 (Philosciidae), B. philippinensis and B. palawanensis from Palawan Island, the Philippines are described as new. B. philippinensis is distinguished from its congeners by the shape of telson with straight sides and slightly protruding distal part with acute apex, while B. palawanensis by its peculiar shape of male pleopod 1 endopod.

  • Littorophiloscia visayanensis n. sp. is described from Visayan islands in the Philippines. In the shape of telson, L. visayaensis is close to L. riedli Strouhal, 1966), L. nipponensis Nunomura 1986, and L. formosana Kwon and Jeon, 1993, but it is easily distinguished by the peculiar shape of male pleopod 1 endopod.

  • During a scientific survey of Korean isopod fauna, we discovered two marine isopods, Limnoria segnoides Menzies, 1957 and Munna japonica Shimomura and Mawatari, 2001, which are new records to South Korea. Limnoria segnoides and M. japonica were collected by SCUBA diving from the subtidal zone of Jeju Island and Yangyang-gun in South Korea, respectively. In this paper, we provide diagnosis and illustrations of the two isopods. Additionally, we provide GenBank accession numbers of partial sequences of mitochondrial cytochrome c oxidase subunit 1 (CO1) of two species.

  • A chaetiliid isopod, Symmius caudatus Richardson, 1904 is newly recorded from Korea with detailed description and illustrations. This species is characterized by the following features: head has well-defined ocular lobes anteriorly projecting; all pereonites do not have any projections dorsally; maxillule has 2 long plumose and 1 short denticulate setae on inner lobe; propodus of pereopod 1 has 11 stout circumplumose setae on ventral margin in female; and pereopod 7 is ambulatory. In this paper, we present the descriptions and illustrations of mature and juvenile males, which have not been known from previous studies, as well as those of female. We also suggested a revised diagnosis of the genus Symmius.
