imberbis, Parachilognathus Bleeker [P.] 1871:37, Pl. 4 (fig. 1) [Verhandelingen der Koninklijke Akademie van Wetenschappen (Amsterdam) v. 12 (art. 2); ref. 6421] Chang Jiang [Yangtze River], China. Holotype (unique): not researched. Original genus should have been Paracheilognathus. Regarded as an original description by some; Günther's Achilognathus imberbis included with question by Bleeker (p. 38) as the same species; probably can consider imberbis Bleeker as a subsequent identification and not an original description. Subjectively invalid; secondarily preoccupied by Acheilognathus imberbis Günther 1868, replaced by Paracheilognathus bleekeri Berg 1907. •Synonym of Acheilognathus chankaensis (Dybowski 1872) -- (Lin in Chen et al. 1998:434 [ref. 23878], Yang et al. 2010:336 [ref. 30786]). 2°Homonym.
