Polyacanthus Cuvier [G.] (ex Kuhl) 1829:227 Masc. Trichopodus colisa Hamilton 1822. Type by subsequent designation. Jordan 1917:129 [ref. 2407] listed Trichopodus colisa Hamilton as type; then in 1919:173 [ref. 2410] Jordan designated Chaetodon chinensis Bloch as type because of earlier restriction by Cuvier & Valenciennes; Cuvier in Cuvier & Valenciennes 1831:353-364 [ref. 4881] placed colisa in a new genus Colisa, but did not establish a type for Polyacanthus. If Jordan is the earliest to validly designate a type, then the type of Polyacanthus is colisa. See Derijst 1997:222 [ref. 23499]. Preoccupied by Polyacanthus Kaup 1827, which was not used as valid after 1899; therefore reversal of precedence according to ICZN Art. 23.9 in favour of Polyacanthus Cuvier 1829. •Synonym of Trichogaster Bloch & Schneider 1801. Current status: Synonym of Trichogaster Bloch & Schneider 1801. Osphronemidae: Trichogastrinae.
