Taxacom: Family Chilodontidae - unresolved homonym in Characiformes and Gastropoda? - now solved

Wed Jun 18 02:06:22 CDT 2025

Sorry, for "Chilodontinae Eigenmann, 1910"  read "Chilodontidae Eigenmann,
1910" above, since I am interested in this as a family level name, not a
subfamily, now to be treated as a synonym of Chilodidae per the recent ICZN
Opinion.
