In the first sentence of Introduction in the original publication, the year “1879” was included in parentheses after "Paraliparis Collett" by the typesetter mistakenly. The correct sentence should read as below:
Paraliparis Collett 1879, one of the most speciose genera (Orr et al. 2019), comprises about 140 species, including 11 from Japanese waters (Kido 1988; Nakabo and Kai 2013; Murasaki et al. 2018, 2019).
