Notes on Homalogastra similis nom. nov. (Ciliophora, Scuticociliatia), a replacement name for the junior homonym Homalogastra binucleata Liu et al., 2020.

Abstract We recently established a new species, Homalogastra binucleata, with a morphological description and phylogenetic analyses based on SSU rRNA gene sequence data (Liu et al. 2020). Helmut Berger (Salzburg, Austria) commented that Homalogastra binucleata Liu et al., 2020 is a junior primary homonym of H. binucleata Song, 1993 , the latter having been transferred to the genus Uronemita Jankowski, 1980 by Liu et al. (2016) . According to article 57.2 of the ICZN (1999), the junior primary homonym, Homalogastra binucleata Liu et al., 2020, is permanently invalid. It is replaced by Homalogastra similis nom. nov.
