Catches of two carangid fishes (Perciformes), Caranx heberi (Bennett, 1830) (two specimens: 251.5-260.0 mm fork length) and Ulua mentalis (Cuvier, 1833) (nine specimens: 203.6-244.0 mm), off Kasasa on the East China Sea side of Kagoshima Prefecture, Kyushu, Japan, represent the northernmost records of these Indo-West Pacific species. Caranx heberi has not previously been recorded north of the equator in the western Pacific, and the northernmost record of U. mentalis has been Taiwan. The Kagoshima specimens are described in detail and their biogeographic implications are discussed.
Three species of alvinocaridid shrimps are recorded from the recently discovered hydrothermal vent fields on the southern Mid-Atlantic Ridge: Opaepele susannae sp. nov., Rimicaris exoculata Williams and Rona, 1986, and Mirocaris fortunata (Martin and Christiansen, 1995). All three species are considered to be vent-endemic. The new species is provisionally assigned to the heretofore monotypic genus Opaepele Williams and Dobbs, 1995, based on overall similarity. Opaepele susannae sp. nov. is primarily distinguished from O. loihi Williams and Dobbs, 1995, the type species of the genus, by the dorsally smooth rostrum with a truncate or rounded apex. It is the first representative of Opaepele known outside the Pacific Ocean.
Two species of the genus Kamaka (Crustacea: Amphipoda: Kamakidae) are recorded and described from Japan. Kamaka excavata sp. nov. occurred in brackish waters of Tokushima, Shimane, Oita, Fukuoka, Kumamoto, and Miyazaki Prefectures. Male gnathopod 2 of this new species has a wide coxal plate, a long, acute process on article 6, and a posteriorly excavated article 7, and in these respects is dissimilar to those of other Kamaka species. Kamaka kuthae Dershavin, 1923 was collected from freshwater in Hokkaido and is fully redescribed herein. The present material agrees very closely with Dershavin's original description. A key to Japanese species of the genus is provided.
A new species and a new subspecies of oribatid mites, Oripoda obliqua and Truncopes moderatus variabilis, are described from Wakayama City, central Japan. These oribatids were collected by beating trees in a shrine forest. Oripoda obliqua is distinguishable from related species by its broad body, its sensilli being mostly covered, and its arched rostral margin. Truncopes moderatus variabilis differs from the nominate subspecies in its almost glabrous prodorsal surface, its humeral projections being half separated from the body outline, and its highly variable number of genital setae.
