  • Two marine tardigrades belonging to the genus Halechiniscus Richters, H. jejuensis n. sp. and H. remanei Schulz are recorded from Jeju Island, Korea. Halechiniscus jejuensis n. sp. is distinguished from the congeners by the shape and position of lateral body processes, the shape of sensory papilla on leg IV, and the contour of head portion not clearly divided into two lobes. A revised key to the nine species of the genus Halechiniscus is prepared.

  • A new marine tardigrade species of the genus Orzeliscus belonging to the family Halechiniscidae is described from the sea coasts of Korea and Japan. This new species is most characterized in having slender, pole-shaped clava with uniform breadth along its whole length. Furthermore, it evidently differs from the congeners by the combination of characters of a hemispherical protrusion on cheek region of the head, a big and bulbous lateral projection between leg III and leg IV, and an elongate papillus terminating with a minute tube on leg IV. 'Orzeliscus cf. belopus' sensu McKirdy, Schmidt and McGinty-Bayly, 1976 from the Galapagos Islands quite resembles this new species in sharing the slender, pole-shaped clava. However, these two Pacific populations are distinguished to each other by body size and shapes of the protrusion on cheek region and the lateral projection between leg III and leg IV. Scanning electron microscope photographs and a key to species of the genus Orzeliscus are also provided herein.

  • Two new marine tardigrade species, Batillipes longispinosus n. sp. and B. orientalis n. sp. are described on the basis of the specimens collected from the intertidal or shallow sublittoral sands of South Korea. Both the present species are characteristic in the absence of any caudal appendage throughout their life span, and bearing the long clava or cephalic appendages with the long spinous process on the femur of legs IV. B. longispinosus n. sp. most resembles B. tuvernatis Pollock, but is easily distinguished from it by the flattened caudal region and prominently developed spine of legs IV. B. orientalis n. sp. is much related to B. roscoffensis Kristensen, in having the wing-formed lateral body prohection between legs III and legs IV, the papillae on the head region, and the smooth caudal region, but discernible from it in the general body shape and the relatively longer spine of legs IV.

  • Eight tardigrade species belonging to the genus Batillipes are recorded from the intertidal and shallow sublittoral sands at 29 localities in South Korea. Batillipes rotundiculus n. sp. is characteristic in having the round caudal protrusion and the blister-like lateral body protuberance between legs III and IV. Five species (B. pennaki Marcus, B. similis Schulz, B. tridentatus Pollock, B. crassipes Tchesunov and Mokievsky, and B. philippinensis Chang and Rho), newly known to Korean fauna, are briefly remarked with illustrations. A key to the eight species of the batillipedid tardigrades from Korea is prepared.

  • Two echiniscoid belonging to genus Anisonyches are recorded from the intertidal or shallow sublittoral coralline sands at Santacruz Island, Mindanao, the Philippines: A. deliquus n. sp. and A. diakidius Pollock, 1975. A. deliquus n. sp. is related to A. mauritianus in the absence of primary calvae and sensory papillae on leg IV with their characteristic claw formation, but discernible from the latter species in the absence of sensory spine on each of the first three leg pairs. We provide some remarks on the two claw types of the genus Anisonyches, that is, diakidius-type and mauritianus-type.
