Two new marine tardigrades, florarctus kwoni n. sp. and Batillipes philippinensis n. sp. belonging to Halechiniscidae and Batillipedidae, respectively, are described on the basis of the specimens sieved from sublittoral coral sands and shell gravels of Palawan Island, the Philippines. florarctus kwoni n. sp. is characterized by the rocket-shaped aliform expansion, with the distal margin of posterior ala flattened. Batillipes philippinensis n. sp. closely resembles B. similis Schulz, 1955 and B. annulatus De Zio, 1962. However, it is clearly discernible from the former by the shape of lateral body projection between leg III and leg IV, and the relative length of cirrus E and the spine on leg IV, and from the latter by the shape of the lateral body projection and the clavar shape. This is the first report of the marine tardigrades from the Philippines.

바다가시곰벌레속 (Halechiniscus)에 속하는 해양완보류 2종 (H. Jejuensis, H. remanei)을 보고한다. 신종인 제주가시곰벌레 (H. Jejuensis)는 몸통 측돌기의 위치와 모양, 제4다리 기부에 난 유두형의 감각톤기의 모양, 그리고 머리의 전단부가 두 갈래로 갈라져 있지 않은 점에서 본 속의 다른 종들과 뚜렷이 구별된다. 지금까지 바다가시곰벌레속에 기록된 9종에 대한 종검색표를 새롭게 작성하였다.

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.

Three new marine heterotardigrades, Archechiniscus symbalanus, and Styraconyx craticuliformis of the family Halechiniscidae and Echiniscoides andamanensis of the family Echiniscoididae, are reported on the basis of the specimens sieved from intertidal barnacles in the Thai coast of the Andaman Sea. Archechinisos symbalanus n. sp. is related to Archehiniscus minutus Grimaldi De Zio and D'Addabbo Gallo, but discernible from it by possessing median cirrus, stylet sheath, sensory spine of leg l, prominent basal processes on all leg pairs, and S-shaped seminal receptacles. Styraconyx craticuliformis n. sp. is similar to S. craticulus (Pollock) in bearing the grid-like dorsal cuticle, but distinguished from it by the shape of claws and cirrophore of primary clava. Ediniscoides andamanensis n. sp. is rebated to Echiniscoides pollocki Hallas and Kristensen and E. sigismundi sigismundi (M. Schultze) in sharing the same patterns of sensory leg appendages and the claw configuration of 8-8-8-7, but characterized by the shape of cirri, pharyngeal apparatus and female gonopore.
