The genus Eurycletodes Sars, 1909 is reported for the first time in Korea. A new species of the genus Eurycletodes was collected from Hansando Island, South Sea of Korea. So far, Eurycletodes comprises 27 species, with no previously recorded species reported in East Asia, including Korea. Eurycletodes (Oligocletodes) vadumus sp. nov. is morphologically most closely related to E. (O.) denticulatus Por, 1967, E. (O.) aculeatus Sars, 1920, and E. (O.) diva Menzel, 2011, but clearly distinguishable from the others based on the following morphological characteristics: absence of A2 exopodal seta, A1 last segment with two inner setae, P4 exp-3 proximal inner seta modified, the ratio of length and of caudal rami (1.6 times), and mandibular palp with three setae. Together with the new species, the number of valid species in this genus has risen to 28. A key to species of the genus Eurycletodes is provided.

A new bitterling, Acheilognathus majusculus is described from 20 specimens collected from the Somjin and Nakdong River, Korea. The new species is similar to Acheilognathus yamatsutae, but distinguished from the latter and congeners by the combination of the following characteristics: 15-21 gill rakers, 37-40 vertebrae, longer barbel, greenish body coloration, nuptial color of males and slightly protrusive snout. A key to species of Acheilognathus from Korea is included.

In this paper we represent a new species, Cteniobathynella ahnerti sp. nov., from South America. The new species is characterized by the heterodont teeth on free margin of labrum, the spine row of the mandible consisting of four thick spines, the presence of two setae on outer distal margin of distal segment of maxillule, the prehensile nature of maxilla and the oblique arrangement of two spines on sympod and the presence of a median spine on the endopod of the uropod.

Although Apiospora Sacc. has previously been considered a sexual morph of Arthrinium species on the basis of phylogenetic, morphological, and ecological diagnoses, a recent study delimited these as different species. Recently, 14 species, including eight new species, of marine Arthrinium have been reported from Korea. Six known species have previously been renamed as species in the genus Apiospora (A. arundinis, A. marii, A. piptatheri, A. rasikravindrae, A. sacchari, and A. saccharicola). However, the eight new species of marine Arthrinium (Ar. agari, Ar. arctoscopi, Ar. fermenti, Ar. koreanum, Ar. marinum, Ar. pusillispermum, Ar. sargassi, and Ar. taeanense) are yet to be studied, and thus the taxonomic status of these species remains to be clarified. In this study, we conducted phylogenetic analyses using the internal transcribed spacer, 28S large subunit ribosomal RNA gene, translation elongation factor 1-alpha, and beta-tubulin regions to confirm the phylogenetic position of these eight species. Based on these analyses, we re-identified the eight Arthrinium species as new combinations in Apiospora. Additionally, among the six known Apiospora species, two (A. piptatheri and A. rasikravindrae) have not previously been recorded in Korea. On the basis of morphological and molecular analyses, we report these as new species in Korea. Herein, we present scanning electron micrographs detailing the morphologies of these species, along with phylogenetic trees and detailed descriptions.

Tenuidraconema koreensis, a new species of free-living marine nematodes, collected from the subtidal coarse sediments and various invertebrates of Namae, is described. The new species differs from T. fiersi Decraemer, 1989, the only other species in the genus, by having the combination of the following characters: the position of twelve cephalic adhesion tubes in both sexes (anterior six cephalic adhesion tubes inserted on the rostrum and posterior six inserted on the body annules), and the number of posterior sublateral adhesion tubes (12 in male and 13 in female) and posterior subventral adhesion tubes (15 in male and 19 in female). This paper contains the description of the new species with illustrations and scanning electron microscope (SEM) photomicrographs. This is the first discovery of the monotypic genus Tenuidraconema outside the type locality.

This paper describes six new species of sponges in the genus Agelas from Kosrae Island, The Federated States of Micronesia. Most Agelasid sponges are known from only tropical regions. All the new Agelas species; A. fragum n. sp., A. kosrae n. sp., A. purpurea n. sp., A. bakusi n. sp., A. vansoesti n. sp. and A. incrustans n. sp. are compared with other valid species that were studied. Six new species differ from the other species by morphology, growth form, skeletal fibres, habitats and spicule size. Agelas fragum n. sp. is characterized by its tuberculate surface and primary fibres with brush-like spicules. Agelas kosrae n. sp. is differs in skeletal structure and have tertiary fibres. Agelas purpurea n. sp. is characterized by primary, secondary and tertiary fibres are all cored with spicules. Agelas bakusi n. sp. is similar to Agelas clathrodes in shape, but differs in the primary fibres. Agelas vansoesti n. sp. is characterized by having acanthostrongyles. Agelas incrustans n. sp. is distinguished by its encrusting and not cavernous interior.

Exacanthomysis marsailiae and Nipponomysis neolingvura are described as new species based on specimens collected with a light trap off the East Sea coast of Korea. E. marsailiae is closely related to Exacanthomysis alaskensis (Banner, 1954) and Exacanthomysis borealis (Banner, 1954). However, E. marsailiae can be distinguished from these species by having slightly grouped spines on lateral margins near the telson apex, and the exopod of male's fourth pleopod more than twice as long as the endopod. N. neolingvura can be distinguished from its closest relative, Nipponomysis lingvura (Murano, 1977), in that the lateral sides of the telson are all armed with spines without any empty space, and that the second segment of the fourth male pleopod is longer than the third one. The report of E. marsailiae from the East Sea of Korea extends the distribution range of the genus Exacanthomysis from the high-latitude North Pacific southward to the mid-latitude waters of the western Pacific. The morphological characteristics of the two current new species are also compared with those of their congeners.

Three new species of Collocheres are described as associates of crinoid and ophiuroid echinoderms from Cheju Island, Korea: Collocheres brevipes n. sp. from the crinoids Comanthus solaster A. H. Clark and Decametra tigrina (A. H. Clark); C. solidus n. sp. from two species of the crinoids Comanthus solaster and Comanthus japonicus (Muller) and one species of ophiuroid-Ophiomastax mixta (Lutken); and C. tamladus n. sp. from the crinoid Catoptometra rubroflava (A. H. Clack). The three species are distinguished from one another and other congeners by the body size, dimension of caudal ramus and free segment of leg 5, and shape and ornamentation of urosome.
