Remarks: This taxon occurred as planktons or periphytic in in Cuba ( Foged 1984) (as Asterionella japonica Cleve ), in Palawan of Philippines ( Podzorski & Håkansson 1987), in Okinawa ( Nagumo & Mayama 2000) and in coasts of Japan ( Suzuki & Nagumo 2004, Suzuki et al. 2013), in Yangtze River estuary ( He et al. 2007), in Guam ( Lobban et al. 2011), and in Chuuk Lagoon of Micronesia ( Park et al. 2018).
