N.B.: Considered a senior synonym of Thaididae and Hickmaniidae by Forster, Platnick & Gray, 1987: 25, contra Lehtinen, 1967: 269 and Marples, 1968: 30. Thaididae was firstly used in spiders by Lehtinen, 1967: 269, but Thaididae Jousseaume, 1888 in Gastropoda has priority (contra Murphy & Roberts, 2015: ix, who regard wrongly 1880 [which is only the year of description of the genus Thaida Karsch, 1880] as the first year of description of Thaididae) (see also Tubbs, 1987).

A. Gertsch & Zapfe, in Zapfe, 1955: 47, type A. manni Gertsch & Zapfe, 1955; not a junior synonym of Thaida Karsch, 1880 (Forster, Platnick & Gray, 1987: 33, contra Lehtinen, 1967: 217).

N.B.: Synonymy with Thaida (Murphy & Roberts, 2015: viii) not sufficiently justified and is not accepted here.
