 A Corrigendum on Morphology and Molecular Phylogeny of Four Trachelocercid Ciliates (Protozoa, Ciliophora, Karyorelictea) Found in Marine Coastal Habitats of Northern China, With Description of a New Genus, Two New Species and a New Combination by Ma, M., Li, Y., Ma, H., Al-Rasheid, K. A. S., Warren, A., Wang, Y., and Yan, Y. (2021). Front. Mar. Sci. 7:615903. doi: 10.3389/fmars.2020.615903 infraciliature SSU rDNA ciliates Karyorelictea Trachelocercidae

In the original article, there was a mistake in naming the new genus. The new genus established in the published article, Foissnerella Ma et al., 2021, is a junior primary homonym of Foissnerella Jankowski, 1986 that belongs to Epistylididae Kahl, 1933. According to article 57.2 of the ICZN (1999), the junior primary homonym, Foissnerella Ma et al., 2021, is permanently invalid. It is replaced by Paratrachelocerca nom. nov. Therefore, the Foissnerella typica Ma et al., 2021 is invalid too, and replaced with Paratrachelocerca typica nom. nov. The following corrections have been made:

Page 1, Abstract, line 1 and line 17, Foissnerella typica was changed to Paratrachelocerca typica;

page 1, Abstract, line 6, Foissnerella was changed to Paratrachelocerca;

page 2, Introduction, line 24, Foissnerella was changed to Paratrachelocerca;

page 2, Sample Collection, Observation, and Identification, line 1, Foissnerella typica was changed to Paratrachelocerca typica;

page 3, Results and Discussion, line 4, Foissnerella was changed to Paratrachelocerca;

page 3, Type Species, line 1, Foissnerella typica was changed to Paratrachelocerca typica;

page 3, Discussion, line 1, line 5 and line 9, Foissnerella was changed to Paratrachelocerca;

page 3, Discussion, line 18 Foissnerella typica was changed to Paratrachelocerca typica;

page 4, Table 2, line 1 and Figure 2, line 1, Foissnerella was changed to Paratrachelocerca;

page 4, Foissnerella typica, line 1, Foissnerella typica was changed to Paratrachelocerca typica;

page 5, Figure 3, line 1, Foissnerella typica was changed to Paratrachelocerca typica;

page 6, Table 3, line 1, Foissnerella typica was changed to Paratrachelocerca typica;

page 13, Figure 11, line 43 and Molecular Phylogeny Based on SSU rDNA Sequence Data, line 3, Foissnerella typica was changed to Paratrachelocerca typica;

page 14, Molecular Phylogeny Based on SSU rDNA Sequence Data, line 1 and line 14, Foissnerella typica was changed to Paratrachelocerca typica.
