Marine tardigrades of the family Halechiniscidae (Heterotardigrada: Arthrotardigrada) are reported from Oura Bay, Okinawajima, one of the Ryukyu Islands, Japan, including Dipodarctus sp., Florarctuswunai sp. n., Halechiniscuschurakaagii sp. n., Halechiniscusyanakaagii sp. n. and Styraconyx sp. The attributes distinguishing Florarctuswunai sp. n. from its congeners is a combination of two characters, the smooth dorsal cuticle and two small projections of the caudal alae caestus. Halechiniscuschurakaagii sp. n. is differentiated from its congeners by the combination of two characters, the robust cephalic cirrophores and the scapular processes with flat oval tips, while Halechiniscusyanakaagii sp. n. can be identified by the laterally protruded arched double processes with acute tips situated dorsally at the level of leg I. A list of marine tardigrades reported from the Ryukyu Islands is provided.
在日本琉球群岛之一的冲绳岛大浦湾发现了海生棘甲熊虫科（异缓步纲：节缓步纲）的海洋缓步动物，包括双足熊虫属物种、武内花熊虫新种、久良嘉吉棘甲熊虫新种、柳中嘉吉棘甲熊虫新种和柱熊虫属物种。将武内花熊虫新种与其同属物种区分开来的特征是两个特征的组合，即光滑的背部角质层和尾翼腹节的两个小突起。久良嘉吉棘甲熊虫新种与其同属物种的区别在于两个特征的组合，即粗壮的头部触须和具有扁平椭圆形尖端的肩胛突，而柳中嘉吉棘甲熊虫新种可以通过位于第一对足水平背侧的、具有尖锐尖端的侧向突出拱形双突来识别。本文提供了一份琉球群岛已报道的海洋缓步动物清单。
