Two new records of scolecid polychaetes, Praxillella pacifica Berkeley, 1929 and Naineris dendritica (Kinberg, 1867), collected from Korean waters are reported here with descriptions and illustrations. Praxillella pacifica can be distinguished from its congeners by the number of asetigerous segments on the posterior region of the body and features of the anal cone and neuropodial spines on setigers 2 and 3. Naineris dendritica is distinguishable from its relatives by the morphology of thoracic neuropodial lobes and the thoracic uncini at the inferior position. In the present paper, keys to Praxillella and Naineris species from Korean waters were also provided.

The taxonomic research based on extensive investigations and specimen collections throughout all varieties of freshwater and marine habitats of Chinese waters, including mainland China, Hong Kong and Taiwan, which involved accounting the vast number of collected specimens, data and literature (both within and outside China) were carried out over the last 40 years. There are totally 361 recorded species of gobioid fishes belonging to 113 genera, 5 subfamilies, and 9 families. This gobioid fauna of China comprises 16.2% of 2211 known living gobioid species of the world. This report represents a summary of previous researches on the suborder Gobioidei. A recently diagnosed subfamily, Polyspondylogobiinae, were assigned from the type genus and type species: Polyspondylogobius sinensis Kimura & Wu, 1994 which collected around the Pearl River Delta with high extremity of vertebral count up to 52-54. The undated comprehensive checklist of gobioid fishes in China will be provided in this paper.

Six phytal harpacticoid species of the genus porcellidium are recorded from 22 algal species in the eastern (Sea of Japan) and southern (Korea Strait) coast of Korea. Among these six species, Porcellidium ofunatense Harris and Iwasaki and Porcellidium gamoi(Harris and Iwasaki) are recorded as new to Korean fauna. Other four species are described as new to science: Porcellidium bipartitum n. sp. found from a single algal species, Procellidium wandoensis n. sp. from ten algal species, Porcellidium acutum n. sp. from five algal species, and Porcellidium brevlcacum n. sp. from two algal species. It is found that the associations between the species of Porcellidium and macroalgae reveal weak specificities.

A hyalid amphipod, Protohyale pumila (Hiwatari and Kajihara, 1981), collected from Jeju Island is reported for the first time in the Korean fauna. The species is characterized by the presence of a short apical spine on the palp article 4 of maxilliped, a distinctly large and blunt cusp on the propodus of male gnathopod 1, and a distal truncate process on the palm of male gnathopod 2. Herein, the present species is described and illustrated. Korean hyalid amphipods now are composed of four species belonging to three genera. Voucher specimens were deposited in the Marine Arthropod Depository Bank of Korea, Seoul National University.

A single specimen of Brama orcini (267.0 mm standard length, SL), belonging to the family Bramidae, was collected by purse seine from Jeju Strait, Korea, in December 2013. The specimen is characterized by having 16 gill rakers, 54 lateral line scales, and 36 vertebrae. B. orcini is distinguished from the most similar species, Brama japonica, by the number of lateral line scales (52-54 in B. orcini vs. 65-75 in B. japonica). We propose a new Korean name "Keun-bi-neul-sae-da-rae" for B. orcini.

Three specimens of Lutjanus ophuysenii (217.8-226.7 mm in standard length) were collected by a gill net at Korea between August 2015 and July 2016. This species has not previously been recorded from Korea. L. ophuysenii is very similar to Lutjanus vitta. But several morphological characteristics distinguish the two species, including the number of lateral line scales (46-49 scales in L. ophuysenii; 49-52 scales in L. vitta), a black spot in the middle part of the longitudinal stripe (present in L. ophuysenii; absent in L. vitta), and the absence of a scale on posterior end of the preopercle in L. ophuysenii (present in L. vitta). The Korean name proposed for L. ophuysenii is "Jeom-jul-tung-dom."

A newly recorded hyalid species, Protohyale (Boreohyale) triangulata (Hiwatari, 2003), of Korean waters is reported with a description and illustrations. In this paper, the validity of its generic and subgeneric categories is considered. Protohyale triangulata has a specific shape of the propodus of gnathopod 1 in the matured male, forming a triangle with a subquadrate posteroproximal corner, and the palm and the posterior margin are not clear. This major characteristic feature serves to distinguish it from other Korean hyalid species. We also reexamined some previous reports of Korean hyalid species. It seems that this species had been confused with Hyale rubra in Korea.

Fourteen species of the family Penaeidae have been previously reported from the Korean waters (Kim, 1977: Cha et al., 2001). Recent collections from the coastal waters of Korea revealed the presence of two penaeid species, Metapenaeopsis lata Kubo, 1949 and Parapenaeopsis cultrirostris Alcock, 1906. These two species have been reported from Japan, East China Sea and Sou China Sea, and the Indo-West Pacific low South China Sea. We present brief notes of these species as two new members of the Korean fauna. (omitted)

Setarches longimanus (Alcock 1894), in the family Scorpaenidae, was collected from Busan and the coastal waters of Jeju Island, Korea, in January and November 2014, respectively. Two specimens are characterized by XI, 10 dorsalfin rays; 19-21 pectoralfin rays; III, 5 anal fin rays; a second preopercular spine much shorter than the first and third; and an interorbital width 11.3 %-11.6 % of the standard length. We also analyzed 587 base pairs of the mitochondrial DNA cytochrome c oxidase subunit I sequences in order to confirm the taxonomic status of the specimen. As a result, the sequences of our specimen almost corresponded to those of Chinese S. longimanus (genetic distance, d = 0.005), but considerably differed from those of S. guentheri (d = 0.120-0.124). We propose the new Korean names "Ma-su-gam-peng-sok" for the genus Setarches, and "Bul-geun-ma-su-gam-peng" for the species S. longimanus.

The crinoid specimens of the genus Anneissia were collected from Nokdong, Korea Strait, and Moseulpo, Jeju Island. The specimens were identified as Anneissia pinguis (A.H. Clark, 1909), which belongs to the family Comatulidae of the order Comatulida. Anneissia pinguis was first described by A.H. Clark in 1909 around southern Japan. This species can be distinguished from other Anneissia species by a longish and stout cirrus, much fewer arms, and short distal cirrus segments. The morphological features of Korean specimens are as follows: large disk (20-35 mm), 28-36 segments and 32-43 mm length cirrus, division series in all 4 (3+4), very stout and strong distal pinnule with 18-19 comb and 40 arms. In Korea fauna, only three species of genus Anneissia were recorded: A. intermedia, A. japonica, and A. solaster. In this study, we provide the morphological description and phylogenetic analysis based on cytochrome c oxidase subunit I.
