Ephydatia fluviatilis

Unfortunately, Naturalis colleague Niels van der Windt was not successful in obtaining sequences from the neotype, presumably because the preservation of the specimen was compromised by having been put into formalin when collected. Robert et al. (2022: Table 1) provided non-type material sequences of Swedish populations of E. fluviatilis (both 28SrRNA and COI, GenBank accession nrs OL985643 and OL970208). Many other specimens from other localities and regions are available in the literature, e.g. sequences of an Irish specimen were published by Morrow et al. [2012, GenBank accession nr. EF591285 (28SrRNA)], of German specimens by Meixner et al. [2007, GenBank accession nrs. AJ843884 and DQ167174 (COI, voucher ZMB 12658) and AJ705048 and DQ167158 (18SrRNA], and of a presumably Belgian specimen by Richelle-Maurer, Van de Vyver & Pomponi (unpublished, directly submitted) [2005, GenBank accession nr. AY578146 (18SrRNA)]. A North American specimen was sequenced by Addis & Peterson [2005, GenBank accession nr. DQ176777 (COI)]. There also many ITS sequences available from GenBank, including sequences from a Chinese specimen by Zhao et al. (2023, GenBank accession numbers OP692697 & OP692698 ).
