Recent studies of Japanese kinorhynchs are reviewed. Kinorhynchs (Phylum Kinorhyncha) are ecdysozoan animals with a body composed of head consisted of mouth cone and eversible introvert, neck, and 11 trunk segments. To date, about 230 species have been recorded worldwide, and all of them are exclusively marine meiobenthic species. In Japanese waters, 20 species have been known so far: of these, 9 species were described as new to science or reported as new to Japanese waters within this decade, and 4 species will be described/reported soon. Studies with the molecular phylogenetic and the total evidence analyses detected the phylogenetic relationships within the phylum, and suggested the new classification system. Phylogeographic study of two Echinoderes species detected the geographic population structures of the species, and suggested several historical events had affected to the population structures and distribution patterns of the two species.

Sternaspid annelids are common and often abundant in the world ocean. They are usually corrected in sandy or muddy bottoms at a variety of depths. Sternaspid annelids are now known as characterized by the morphology of ventro-caudal shield, papillae of the body surface and posterior shield chaetae. Although sternaspid annelids recorded from Japan have been called as Sternsapis scutata since 1930s works, we could record two genera and seven species from Enshu-Nada, Kumano-Nada and off Sendai, East coast of Japan: Sternsapis scutata sensu strict, S. affinis, S. islandica, S. thalassemoides, S. costata, Petersenaspis capillata, and P. palpallatoci. Sternaspis has seven abdominal chaetigers and shield with radial ribs, concentric line or both. Petesenaspis has eight abdominal chaetigers and shield with poorly distinct ribs but no concentric line.

The lernaeopodid copepod Salmincola markewitschi Shedko and Shedko, 2002 was collected in July 2019 from the buccal cavity of whitespotted char, Salvelinus leucomaenis (Pallas, 1814) (Salmonidae), reared at the Ishikawa Prefecture Fisheries Research Center (36°15′11″N, 136°25′17″E) in Kaga, Ishikawa Prefecture, central Japan. This represents the first record of Salmincola markewitschi from Ishikawa Prefecture. All of the four whitespotted char examined (263–324 mm standard length) were infected each by 2–5 adult females of Salmincola markewitschi. The adult female of copepod is described. The species is considered to have been introduced along with infected whitespotted char transported alive from a commercial trout farm in the same prefecture into the research center in January 2019. However, no infection was found after September 2019, which was caused by manual removal of copepods in July 2019 and their possible mortality due to unusually high water temperatures (up to 23℃) in August 2019. Since Salmincola markewitschi is morphologically similar to copepods previously reported as “Salmincola carpionis (Krøyer, 1837)” from salmonids (mainly chars Salvelinus spp.) from various localities of Japan, it is desirable to reidentify those copepods.

The Duskytail Grouper, Epinephelus bleekeri (Perciformes: Serranidae), is recorded from Tanega-shima and Amami-oshima islands and the Yaeyama Islands in the Ryukyu Islands, southern Japan on the basis of six specimens (232.6-581.2 mm standard length). In addition, several records of E. bleekeri by photographs and/or observations from Kanagawa, Kochi, Ehime, Miyazaki, and Kagoshima prefectures are confirmed. Because E. bleekeri has previously been recorded from Taiwan and southward, the present specimens represent the first reliable records of the species from Japanese waters on the basis of collected specimens. Distributional implications of E. bleekeri in Japanese waters are discussed.

Isactinernus quadrilobatus Carlgren, 1918, the only species of genus Isactinernus, is characterized by an oral disc with four equally-sized lobes. In 2003 Synactinernus flavus Carlgren, 1918, which is characterized by four large and four small lobes alternately arranged, was synonymized into I. quadrilobatus because the difference of lobe shape was thought to be intraspecific variation, and thus the genus Synactinernus was also synonymized into Isactinernus. However, our molecular phylogenetic analysis of Actinernidae including I. quadrilobatus collected from the Kumano Sea revealed that I. quadrilobatus is genetically distinct from S. flavus. Our morphological comparison between the two species supported the result of the molecular analysis. Consequently, the genus Synactinernus was re-established and separated from Isactinernus. Additionally, during this study, we discovered and described an additional species of the genus, Synactinernus churaumi Izumi and Fujii, 2019.

A single specimen of a lutjanid fish, Lutjanus johnii (445mm in standard length), was collected from the Kuro-shima Island, Nichinan, Miyazaki, Kyushu Island, Japan. The species is distinguished from other members of the genus by the following combination of characters: a black ocellus larger than eye mainly above lateral line and below anterior soft dorsal-fin rays; longitudinal scale rows on back parallel to lateral line; a brownish dark spot on exposed area of each scale on body. This occurrence represents both the first record from the Japanese waters and the northernmost record on the basis of specimen. Morphological features and coloration of the Japanese specimen are described in detail, and the standard Japanese name, Kadogawa-fuedai is given.

In Japan, 111 species (including 11 unidentified taxa) of epicaridean isopods have so far been recorded. All species are parasites, infesting various crustacean hosts, such as Decapoda, Ostracoda, Cirripedia, Mysidacea, and etc. Their larvae are known from ectoparasites of pelagic copepods. In the present paper, 121 species of crustacean hosts of epicaridean isopods are listed (1 species of Ostracoda, 8 of Copepoda, 1 of Balanomorpha, 1 of Rhizochephala, 2 of Mysidacea, 11 of Penaeidea, 33 of Caridea, 1 of Astacidea, 5 of Thalassinidea, 27 of Anomura, 30 of Brachyura, and 1 of unknown taxa).

Diverse aquatic organisms are living in the immediate freshwater environments such as the rice field, pond and ditch. This study reports a freshwater ostracod fauna of rice field and spring from Fuji and Fujinomiya, Japan. We found 14 species (13 genera), and Pseudocandona pratensis (Hartwig, 1901) is newly recorded from Japan. The morphological characters, distribution in Japan, and taxonomic remarks are provided for these species. And also five species were given the new Japanese name. We discussed on the distribution of Dolerocypris ikeyai Smith and Kamiya, 2006 and Stenocypris hirutai Smith and Kamiya, 2006 found from rice field. Both species has been reported from runoff of spring, seeps, interstitial environment. We regarded their reduced swimming setae on antenna as an adaptive character to shallow and gently water flow. Population of rice field of this two species could be originated from the source of an irrigation channel, and they might be incidentally stayed in the rice field.

Nematodes of the genus Phasmarhabditis Andrássy, 1976 (Secernentea: Rhabditida: Rhabditidae) are terrestrial gastropod parasites and mainly target land slugs. In this study, land slugs were surveyed at 14 locations in seven prefectures of Honshu Island, Japan, to determine Phasmarhabditis spp. infection. Juvenile nematodes of unknown species were found in Meghimatium bilineatum Benson, 1842, at five of the 14 locations. The prevalence and mean intensities ranged from 4.5% to 93.3% and from 4.7 to 22.5 nematodes per host, respectively. A total of 881 juveniles were incubated with slug tissues for 2–10 days, and subsequently developed into adult stage showing the diagnostic characteristics of Phasmarhabditis spp. No nematodes were found from slugs of the genus Lehmannia sampled where M. bilineatum were infected, indicating a difference among host species in their sensitivity to the nematodes. Twenty M. bilineatum from Meguro in Tokyo, Japan, where the prevalence in the host population was >90%, were maintained under laboratory conditions. After 23 days, 11 of the 20 slugs died and the cadavers were infected with numerous nematodes. Since three species of Phasmarhabditis nematodes are known to be lethal to terrestrial gastropods, the nematodes we sampled possibly have a lethal effect on the host slugs.
