Oecophoridae (Lepidoptera: Gelechioidea), the concealer moths, is worldwide in distribution and comprises more than 4,000 described, particularly in Australia with over 3,000 endemic species. To date, the phylogenetic relationships of Oecophoridae have been poorly known, except a few works on the higher-level phylogeny of the superfamily Gelechioidea which includes some species of Oecophoridae. This study is the first comprehensive molecular phylogenetic analysis of Oecophoridae, based on 4,395 base pairs of mitochondrial protein coding gene (COI), nuclear ribosomal RNA genes (18S and 28S) and nuclear protein coding genes (IDH, MDH, Rps5, EF1a and wingless) for 82 taxa. Data were analysed using maximum likelihood (ML), maximum parsimony (MP) and Bayesian inference (BI) phylogenetic frameworks. The results are shown that the family Oecophoridae is not monophyletic, as the genus Casmara is closely clustered with Stathmopodidae far from the Oecophorid lineage and the genera Tyrolimnas and Phaeosaces are closely clustered with Depressariinae in the Elachistid lineage. Main clade of Oecophoridae comprises Xyloryctinae previously assigned to Xyloryctidae, closely claded with New Zealandian Oecophorids including the genera Hierodoris, Gymnobatra and Izatha; the problematic position group, Acryptolechia spp., Deuterogoniinae and Oecophorinae.
