  • The branchiobdellidan species Holtodrilus truncatus (Liang, 1963) is reported for the first time in Korea. The genus Holtodrilus Gelder and Brinkhurst, 1990 is monotypic within the family Xironodrilidae, and the genus and family of this species are also new to the Korean fauna. The branchiobdellidan specimens were collected from the exoskeletons of the freshwater atyid shrimp, Neocaridina sp., sampled from the 'Andeok Valley', Jeju-do Province, South Korea. Holtodrilus truncatus is characterized by its terete body form, 7/7 dental formula (with a large medial tooth and three pairs of smaller lateral teeth), and no trunk appendages. In addition, we determined a partial sequence of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene as a DNA barcode marker for H. truncatus. The present study is the first record of the branchiobdellidan occurrence on a non-crayfish host (shrimp) in Korea. To date, seven species (four genera in three families) of branchiobdellidans have been reported in the Korean fauna.

  • Three ciliate species, Australocirrus australis (Foissner, 1995) Kumar and Foissner, 2015, Rimaleptus longitrichus ($Vd^{\prime}a{\check{c}}n{\acute{y}}$ and Foissner, 2008) $Vd^{\prime}a{\check{c}}n{\acute{y}}$ and Foissner, 2012, and Frontonia subtropica Pan et al., 2013, that were previously unreported in Korea were collected from terrestrial and marine habitats in Korea. Using live observation and protargol impregnation, the three species were identified using a combination of the following characteristics: Australocirrus australis, the distance between the anterior pretransverse cirrus and the anteriormost transverse cirrus (0.6-2.1% of body length) and the arrangement of the transverse cirri (oblique row); Rimaleptus longitrichus, the arrange of contractile vacuoles and longitudinal ciliary rows anteriorly spaced; Frontonia subtropica, number of somatic kineties (approximately 115 rows) and vestibular kineties (5 rows).

  • Three new species of Hemicyclops, H. parilis, H. nasutus and H. membranatus are described from Korean coasts. Hemicyclops parilis n. sp. is closely similar to H. gomsoensis Ho and Kim, but distinguishable from the latter species by having the different shape of genital double somite and spermatophore. Hemicyclops nasutus n. sp. is distinguishable from congeners by having five setae on the first segment of antennule and the ratio 4.26 : 1 of the length to width of caudal ramus. Hemicyclops membranatus n. sp. is characterized by the possession of the membranous fringe along margins of cephalothorax and a claw on the third antennal segment.

  • Three novel species, Philodromus daoxianen n. sp., P. ganxiensis n. sp., and P. longitibiacus n. sp., are described based on the specimens collected from Hunan Province, China. P. daoxianen is similar to P. rufus, but its spermathecae is calabash-shaped, that of the latter spherical. It is also similar to P. kendrabatai, but differs in the form of atrium, distance between two spermathecae and dorsal markings of the abdomen. P. ganxiensis differs from other species of the genus Philodromus in eplgynum by a pair of sword-shaped apophyses, palpal organ with slightly wider distal end of a tibial apophysis, and knife-shaped membranous median apophysis. P. longitibiacus differs from other related species in long and thin palps and legs especially tibia of palps, which is about 4.5 times as long as the cybium and basal portion of embolus strongly sclerotized.

  • Based on four juvenile specimens of Lutjanus collected from the southern coast of Jeju Island, three species, L. argentimaculatus, L. fulviflamma, and L. quinquelineatus, are described as the first record from Korea. The first species is easily differentiated from other lutjanid juveniles by distinct coloring of the dorsal, pelvic, and anal fins as well as two blue lines below the eye; the second species is characterized by having six yellowish brown stripes below the lateral line and a black spot on the side; the third species is identified by five longitudinal blue stripes and a black spot on the side when fresh. The new Korean names "Bul-geun-tung-dom," "Yuk-seon-jeomtung-dom," and "O-seon-tung-dom" are proposed for L. argentimaculatus, L. fulviflamma, and L. quinquelineatus, respectively.
