Material examined. Sejong Weir , 23 September 2014 ; Baekgok Reservoir , 30 September 2016 .

Substratum. Wood.

Remarks. In Korea, this species has been reported with only floatoblasts by Seo (1998; 2005; 2011), because no colony was ever found from Korean freshwater. We fortunately collected only one colony attached to some wood at Sejong Weir. Young colony with only 9 zooids is about 2 mm in diameter, very small, transparent, soft, and gelatinous ( Fig. 2A ). Short tubular zooids are arranged concentrically and have up to 70-85 tentacles. It was easy to identify the species by its characteristic spines at both sides of the floatoblast( Fig. 2B ) taken out of the colony.

Distribution. Korea, Japan, China, Taiwan, Myanmar, India, Java, Israel, Australia, North America, and Africa.
