This study was conducted to review the family Psychidae in the Korean peninsula with taxonomic arrangement, some biological notes and phylogenetic analyses. In this study, totally 20 species of 8 genera belonging to 5 subfamilies in the family were recognized from Korea. Among them, a new subfamily Ceratostiinae subfam. nov. is proposed based on the type genus Ceratosticha Meyrick. Four new species are described as new to science. Also, six newly recorded species are first recorded in this study. In addition, ecological characteristics, distributional ranges, host plants and biological notes including life cycle and parasites on the larva were described.
A phylogenetic and a molecular clock analysis were conducted to construct the systematic relationship and evolutionary process within the family Psychidae species.
