Abstract Phylogenetic relationships within the megadiverse lepidopteran superfamily Gelechioidea have been poorly understood and consequently the family level classification has been problematic. An analysis of phylogeny using 193 characters, including 241 informative character states, derived from larval, pupal and adult morphology and larval ecology, was performed to resolve the phylogeny of the Gelechioidea. 143 species representing the diversity of the putative Gelechioidea were included, supplemented with 13 species representing 11 other Ditrysian families. The monophyly of the Gelechioidea was supported, although only with homoplastic characters. The putative position of the Gelechioidea as the sister group of the Apoditrysia was not supported, since the Gelechioidea was nested within this clade. The Gelechioidea was divided into two main lineages: (1) the gelechiid lineage constituting Deoclonidae, Syringopainae, a re‐composed Coleophoridae (including Coelopoetinae and Batrachedrinae as paraphyletic with Stathmopodinae, and Coleophorinae nested within it), Momphidae, Pterolonchidae, Scythrididae, Cosmopterigidae, and Gelechiidae, and (2) the oecophorid lineage constituting the “autostichid” family assemblage (including taxa formerly assigned to Autostichinae, Holcopogoninae, Symmocinae, Glyphidoceridae and Lecithoceridae), Xyloryctidae s.l. (including a paraphyletic Xyloryctidae of authors, some oecophorids of authors, Deuterogoniinae and Blastobasinae), Oecophoridae s.s ., Amphisbatidae s.s ., Carcinidae, Stenomati[n/d]ae, Chimabachidae and Elachistidae (including Depressariinae s.s ., Telechrysis , Ethmiinae, Hypertrophinae s.l. , miscellaneous “amphisbatids” sensu authors, Aeolanthinae, Parametriotinae, Agonoxeninae and Elachistinae). Detritivory/fungivory may have evolved only twice within Gelechioidea, though the evolution of larval food substrate use frequently reverses. To avoid an unnecessary further proliferation of names, it is recommended that no further family group names are introduced within the Gelechioidea, unless based on a rigorous analysis of inter‐relationships.
