Abstract

We report recent occurrences of Fragilaria longifusiformis ssp. eurofusiformis Lange-Bertalot & S. Ulrich from Japanese lakes. This diatom was firstly found from Uokiri Dam Reservoir on the Yahata River, Hiroshima in 2011, followed by Lake Kasumigaura, Ibaraki in 2014 and Lake Biwa, Shiga in 2021. It is considered to be introduced into Japan around 2010. We displayed morphological characters of Japanese specimens and distinguishing points from other confusing species.
