A recently published brief assessment of the phylogeny of Scopelophila (Mitt.) Lindb. and related genera ( Kuznetsova et al., 2023) showed that two of the species involved, namely Scopelophila ligulata (Spruce) Spruce and S. cataractae , differ significantly in their plastid DNA sequences. These new data in combination with the already well understood morphological differences between these two taxa ( Noguchi 1956, Zander 1967) suggest they deserve to be segregated into separate genera. However, both of the well-known generic names that have been applied to these species, Merceya Schimp. and Scopelophila (Mitt.) Lindb. are based on the same nomenclatural type. When Wijk et al. (1967: 376) designated S. ligulata as the type of the older genus Scopelophila they also made Merceya superfluous, since it only included that species when it was described. Consequently, another generic name is needed for S. cataractae . Fortunately, the genus Merceyopsis is already available and its type is a synonym of S. cataractae . Zander (1993) cited Merceyopsis pellucida Broth. & Dix. as the type of Merceyopsis , but an earlier typification was already made by Chen (1963) with Merceyopsis sikkimensis (Müll. Hal. ex Renauld & Cardot) Broth. & Dixon. In practice this makes little difference, since both names are synonyms of S. cataractae . Thus, we propose reviving this generic name by establishing a new combination in it for the species presently known as Scopelophila cataractae .

While preparing the taxonomic treatment of the family Rhabdoweisiaceae, Fedosov et al. (2021) accepted the typification of the genus Kiaeria by Ochyra et al. (2008: 177) with K. starkei (F. Weber & D. Mohr) I. Hagen. As a result, the name Kiaeria was considered a synonym of the earlier Arctoa Bruch & Schimp. , while Kiaeria falcata (Hedw.) I. Hagen and three closely related austral species previously classified in the genus Blindia Bruch & Schimp. were placed in the newly established genus Pseudoblindia . When proposing these nomenclatural novelties, the authors overlooked the fact that the type of Kiaeria must be Dicranum falcatum Hedw. since Kiaeria is actually a replacement for Dicranum sect. Falcata Bruch & Schimp. , which is automatically typified by that species (by Art. 10.8, Turland et al. 2018). Even if the description of Kiaeria is considered independent of Dicranum sect. Falcata , its type would still be Kiaeria falcata because Abramov & Savicz-Lyubitskaya (1963: 384) effectively designated that species as its type. Consequently, the later typification of Kiaeria with K. starkei (Ochyra et al. 2008) is superfluous. Furthermore, because K. falcata was included in the original circumscription of Pseudoblindia , that genus is illegitimate (Art. 52.1, Turland et al. 2018), and the name Kiaeria should have been adopted for that clade. Therefore, the other three species, assigned b y Fedosov et al. (2021) to Pseudoblindia need new combinations in Kiaeria which are established below.
