  • A sea star was collected from the Korea Strait in the waters adjacent to eastern Jeju Island, Korea ($33^{\circ}39^{\prime}86^{{\prime}{\prime}}N$, $127^{\circ}33^{\prime}12^{{\prime}{\prime}}E$) at a depth of 92 m on November 5, 2016. This specimen was identified as Marginaster paucispinus Fisher, 1913, from the family Poraniidae of the order Valvatida, based on morphological characteristics. The genus Marginaster Perrier, 1881 and M. paucispinus, which were first reported in the South China Sea, are new to the Korean fauna. Partial sequences of mitochondrial COI and 16S ribosomal RNA of M. paucispinus were have been determined for the first time and were deposited in GenBank. They are the first molecular records for the genus Marginaster.

  • Two species of the genus Parthenocodrus Pschorn-Walcher, 1958 (Hymenoptera: Proctotrupidae) are reported: P. elongatus from Japan and South Korea and P. puncticauda from South Korea. Parthenocodrus elongatus is easily distinguished by having posterior surface of propodeum without transverse carinae and ovipositor sheath with distinct longitudinal striations. Parthenocodrus puncticauda is easily distinguished by having posterior surface of propodeum with transverse carinae and ovipositor sheath without distinct longitudinal striations. This genus is also newly recorded in each country. Redescriptions and photographs of the diagnostic characters are provided. All specimens for this study are deposited in the Yeungnam University (YNU), Gyeongsan-si, South Korea.

  • An anisogammarid amphipod, Eogammarus possjeticus (Tzvetkova, 1967), is newly recorded from Jindo Island, Korea, with a detailed description and illustrations. The species belonging to the genus Eogammarus are sharing several plesiomorphic characteristics, so they are similar to each other. However, Eogammarus possjeticus can be discriminated from congeners by the following characters combined: appendages are not fossorial, setations of antennae are weak, and the number and position of robust setae on pleonal epimera, urosomes, and telson are different from its congeners. This is the first record of the genus Eogammarus Birstein, 1933 from Korean waters.

  • We report two new records of Korean fauna of genus Exochus, as well as two newly recorded species from China and Mongolia each. Specifically Exochus suborbitalis Schmiedeknecht, 1924 and Exochus thomsoni Schmiedeknecht, 1924 from Korea, Exochus kusigematii Tolkanitz, 2007 and Exochus suborbitalis Schmiedeknecht, 1924 from Mongolia and Exochus semilividus Vollenhoven, 1875 and Exochus thomsoni Schmiedeknecht, 1924 from China are reviewed. The genus Exochus have been reported 19 species from China and 21 species from Mongolia. Diagnosis of the four unrecorded species, host information, distributions and illustrations of external characters are provided.

  • A taxonomic study was made on the genus Tremex (Hymenoptera: Siricidae) in Korea. The study was carried out with specimens collected throughout the country from 1996 to 1998 and preserved in museums and laboratories of Universities in Korea and in other countries. As a result of this study, the genus Tremex found in Korea now consists of 5 species including one newly recorded species, Tremex contractus Maa and one new species, Tremex nigrocephalus n. sp.

  • Pelagic tunicate, Thetys vagina Tilesius, 1802, is newly reported from Korean waters. The genus Thetys Tilesius, 1802 is also first recorded as Korean fauna. Thetys vagina is the only valid species in the genus Thetys. It is distinct from other genera by having at least 16 body muscles widely interrupted, no anterior proboscis, bent alimentary canal in the solitary oozooid, and five narrow body muscles, no ventral peduncle, an almost compact loop alimentary canal in the aggregate blastozooids. The specimens of T. vagina examined in this study were collected at the subtidal zone of Ulleung-do Island by scuba diving. In this paper, the detailed descriptions and photographs of both the solitary and aggregate living forms of T. vagina are provided.

  • An asteroid specimen was collected by using a fishing net from the waters near Daejin harbor, in the East Sea of Korea on 3 Mar 2017. Based on morphological characteristics, the specimen was identified as Aleutihenricia beringiana (Djakonov, 1950), belonging to the family Echinasteridae, of the order Spinulosida. The genus Aleutihenricia was first described by Clark and Jewett, 2010. This species can be distinguished from other Aleutihenricia species by having a roundish protruding shape of abactinal and actinal plates, the number of abactinal spines bearing three to eight spinelets, and the number of adambulacral spines comprising six to eight spinelets. This is the first report of the genus Aleutihenricia and A. beringiana in Korea.
