The Arctiini are a tribe of tiger moths in the Erebidae family.

The tribe was previously treated as a higher-level taxon, the Arctiinae subfamily, within the Arctiidae family of lichen and tiger moths. The ranks of the family and its subdivisions were lowered in a recent reclassification while keeping the contents of the family and its subdivisions largely unchanged. These changes in rank triggered changes in the suffixes in the names. The Arctiidae family as a whole was reclassified as the Arctiinae subfamily within the Erebidae family. The original Arctiinae subfamily was lowered to tribe status as Arctiini, and its original tribes were lowered to subtribe status by changing the -ini suffix to -ina (e.g., Callimorphini became Callimorphina). Thus, the name "Arctiinae" used to refer to only a subgroup of the entire group of lichen and tiger moths, but now it refers to the entire group.
