Nomenclatural note
"No evidence of an embedding process of the terminal meristematic cells like what occurs in species of Clathromorphum and Neopolyporolithon was observed (Adey and Johansen 1972: fig. 15; Lebednik 1977a: figs. 8e, 14a, 19d; Figure 7a,e,g). Hence, we can support neither the transfer of L. arcticum to Neopolyporolithon nor its synonymy with Neopolyporolithon loculosum, the latter species also being described by Kjellman a few years later from the Bering Island in the Bering Sea (Kjellman 1889, as Lithothamnion loculosum). Furthermore, the proposed synonymy was based on a comparison between a partial (263 bp) DNA sequence from type material of L. arcticum (UPS) and full-length sequences of 1,384 bp of Neopolyporolithon loculosum (Gabrielson et al. 2019), a method that has been criticized because it assumes that no further changes take place in the unknown (longer) part of the sequence (Athanasiadis 2020a: 75)."
