038EE907BE1D472EEE92B1FDFAD0F9FE.taxon	description	Notes: Recent revisions based on molecular phylogenies of the keeled and canal raphe-bearing diatom genera Surirella, Cymatopleura, Rhopalodia, and Iconella, revealed monophyly of the genus Surirella. This necessitated nomenclatural transfers of many nested taxa within Surirella (Ruck & al. 2016), including the freshwater forms of Cymatopleura. However, Cymatopleura internationalis from Glacier National Park, Montana, USA, described by Bahls (2013), was not included in the transfers to Surirella proposed by Ruck & al. (2016) and Jahn & al. (2017).	en	Edlund, Mark B., Station, Elena Jovanovska St Croix Watershed Research (2024): Diatoms of North America: Nomenclatural transfers within the Bacillariophyceae 1. Notulae Algarum 319: 1-3
038EE907BE1D472FEE92B350FCA7FEDA.taxon	description	PhycoBank Registration: http: // phycobank. org / 104260 Notes: Recent revisions based on molecular and morphological phylogenies of Gomphonema and its allies (Jahn & al. 2019) resulted in the recognition of a monophyletic grouping around Gomphonema olivaceum (Hornemann) Ehrenberg and allies. Gomphonema olivaceum was originally described as Ulva olivacea Hornemann (1810: fasc. 24; pl. MCCCCXXIX [1429]), which was transferred as Gomphonella olivacea (Hornemann) Rabenhorst (1853: 61, pl. IX [9]), the generitype of Gomphonella Rabenhorst, 1853. As a result, Jahn & al. (2019) resurrected the genus Gomphonella to define this monophyletic grouping. One taxon that was not transferred on the basis of this resurrected name was Foged’s Gomphonema olivaceoides var. densistriatum, which has all the characters (Foged 1963, Bishop 2017) of the resurrected genus Gomphonella, _ necessitating this transfer and a new name at the species level as Gomphonella densistriata (Levkov) R. Jahn & N. Abarca is already occupied.	en	Edlund, Mark B., Station, Elena Jovanovska St Croix Watershed Research (2024): Diatoms of North America: Nomenclatural transfers within the Bacillariophyceae 1.

038EE907BE1C472CEE92B42FFB88FC97.taxon	description	Notes: Recent recognition that several generic diatom names were based on descriptive or adjectival terms led to new validated names, including Decussatophycus (Guiry & Gandhi. 2019), Delicatophycus (Wynne 2019), Pulchellophycus (Edlund & Wynne 2019), and others (e. g. Blanco & Wetzel 2016, Turland & al. 2018). However, Cymbopleura tundraphila, described by Bahls (2017) from Nunavut, Canada (Coppermine River, September Mountains Lake), shares diagnostic features (Bahls 2018) with the recently validated genus Delicatophycus, justifying this transfer, as suggested by Bahls (2019: 22).
