The genus Odontopsen Tsuneki was erected by Tsuneki (1964) as a subgenus of the genus Psen Latreille, 1796. Bohart and Menke (1976) raised it to an independent genus. The type species, O. hanedai (Tsuneki, 1964) was found in the Konsei-Pass Nikko, at about 2100 m altitude, in the mountains of central Honshu Island, Japan. No other species of this genus was found in the following almost half a century.

Three new species of Harpellales, collected on Mt. Tsukuba, Kanto Plain on Honshu Island, are described. Stachylina philoricola, derived from midgut of Philorus sp. (Blephariceridae: Diptera), and Lancisporomyces tsukubaensis, derived from the hindgut of Amphinemura sp. (Nemouridae: Plecoptera) nymphs, are described. Blephariceridae is newly added to the host insect families of Harpellales. A new genus, Zygopolaropsis, is proposed to accommodate the new species Z. sphaerica, derived from the hindgut of Baetis thermicus (Baetidae, Ephemeroptera) nymphs.

Four species of palaeonemerteans, including Carinina plecta sp. nov., Callinera nishikawai sp. nov., Hubrechtella ijimai comb. nov., and Hubrechtella kimuraorum sp. nov., are described from the Pacific coast of Honshu Island, Japan. The genus Coeia Takakura, 1922 is considered to be a subjective junior synonym of Hubrechtella Bergendal, 1902. Carinina plecta sp. nov. can be distinguished from other congeners by possessing a rhynchocoel wall principally composed of interwoven circular and longitudinal muscle fibres, a condition similar to that in another palaeonemertean genus, Carinoma, as well as certain members in the Hoplonemertea. Callinera nishikawai sp. nov. possesses a remarkable stylet-like apparatus in the proboscis, a feature that has never been reported for any other palaeonemertean. The characteristic ‘tail’ in Hubrechtella (= Coeia) ijimai comb. nov. can be regarded as a heterochronic retention of the structure that appears only in juveniles of other congeners. Hubrechtella kimuraorum sp. nov. has a broad U-shaped blood lacuna in the foregut region before it ramifies into a vascular plexus.

AbstractThis study examined characteristics of near-inertial internal waves (NIWs) associated with the background mesoscale field near the Tsushima Warm Current. Observational stations off Sado Island were visited recurrently to assess spatiotemporal changes of fine-scale and microscale properties of seawater. Also, NIWs were inspected in terms of relative vorticity and total strain in surface geostrophic motion. During summer expeditions in 2019, current and hydrographic surveys at the rim of an anticyclonic eddy provided clear evidence of downward-travelling NIWs, which were most amplified near the depth of lower pycnocline. The amplification of NIW coincided with elevation in the dissipation rates of turbulent kinetic energy (TKE) and microscale variation of temperature. The fall 2019 expedition found details of wave and turbulence properties associated with the mesoscale structure of paired vortices, where a cyclone and anticyclone were, respectively, adjacent to the east and west. Amplified signals of NIW-related vertical shear and TKE dissipation were found at isopycnals between the dipole cores. From the theoretical perspective of internal wave, the baroclinic term attributable to vertical shear of geostrophic current was interpreted as inducing downward travel of NIW through the lower pycnoclines between the dipole cores. It is also noted that cyclones, passing through the central part of Sea of Japan, can deliver kinetic energy into 10-km scale internal waves as a consequence of interaction between easterly wind and mountainous topography in the Honshu Island.
