Abstract
Abstract.The classification of the gelechioid family Elachistidae (Lepidoptera) is revised on the basis of a phylogenetic analysis. Pee‐Wee analysis of 131 characters of adult and pupal morphology and larval mode of life, coded for seventy elachistid species, results in a classification with three recognized genera:Perittia,StephensiaandElachista.Elachistais further divided into four subgenera. The phylogenetic relationships of the genera and subgenera are (Perittia(Stephensia((E. sg.Dibrachia(E. sg.Hemiprosopa,E. sg.Aphelosetia)) (E. sg.Elachista)))). Twenty‐four new generic synonyms and thirty‐eight new generic combinations of species are proposed. A checklist is given for the species of Elachistidae in their revised generic combinations, including nine new synonymies. Due to secondary homonymy,Elachista dasycaranom. n. is proposed as a new name forEurynome albellaChambers.
