The family Thyatiridae is one of the most compact large Macroheterocera families, comprising about 2 subfamilies, 45 genera, and 300 described species in the world (László et al. 2007). Thyatiridae has been treated as a member of the Geometroidea - Drepanoidea - Uranoidea phyletic trunk but its rank and position within this monophylum is variable in the different works. Recently, László et al. (2007) strongly suggested that it is not reasonable to relegate the Drepanidae, Thyatiridae, and Cyclidiidae as a subfamily of Drepanidae, and supported to retain the family ranks for them. Thus, we follow the system treating them as family ranks. In this study, we provided about the revised genus, species, subspecies name and synonyms of the Thyatiridae with the addition of the information mentioned.

Horithyatira kawamurae (Matusumura) (Thyatiridae, Lepidotpera) is reported for the first from Korea. Adults of H. kawamurae and its closely allied species, Thyatira batis (Linnaeus), are examined for comparison and redescription of H. kawamurae with the female genitalia is provided.
