ERYTHRINIDAE Valenciennes, 1847 GMT Mattox, OT Oyakawa, K Mathubara

Erythricthini Bonaparte, 1835 (correct spelling Erythrichthini):16. Type genus: Erythrichthys Bonaparte, 1831 . Additional comments: Bonaparte (1835:16) misspelled Erythricthini. Bonaparte (1837:7); corrected the stem to Erythrichthini. Senior objective synonym of Erythrinidae Valenciennes, 1847 , but not the name in prevailing recent practice.

Érythroïdes Valenciennes in Cuvier, Valenciennes, 1847:480 . Type genus: Erythrinus Scopoli , 1777. Additional comments: Name was latinized to Erythrinidae by Richardson (1856:250). Junior objective synonym of Erythrichthini Bonaparte, 1835.

Gender: Masculine. Additional comments: Erythrinus was first published by Gronovius (1763:114) in a work that was subsequently placed on the Official Index of Rejected and Invalid Generic Names in Zoology, ICZN: Opinion 261, 1954, which makes the name unavailable from that publication.

Erythrichthys Bonaparte, 1831:182 . Type species: Synodus erythrinus Bloch, Schneider, 1801 . Type by monotypy. Gender: Masculine.
