A Revision of the Austrlian Genus Epitymbia Meyrick, with Remarks on the Epitymbiini (Lepidoptera: Tortricidae)

Abstract

Nine species of Epitymbia Meyrick are recognized in this revision: alaudana Meyrick [=periopa (Meyrick); =cydropis (Meyrick)], cosmota (Meyrick) [=heliochares (Lower), syn. nov.; =callizyga (Lower)], scotinopa (Lower), eudrosa (Turner), comb, nov. [=pyrrhocremna (Meyrick), syn. nov.], apatela, sp. nov., eutypa (Turner), sp. rev. and comb. nov., passalotana (Meyrick), comb. nov. [=semiophora (Turner), syn. nov.], dialepta, sp. nov., and isoscelana (Meyrick), comb. nov. [=thetis (Butler), syn. nov.]. One generic and three specific synonymies are confirmed and one generic and four specific synonymies are newly established. Two lectotypes are designated and four new combinations are proposed. All species except eudrosa, which is also found in New Guinea, are endemic to eastern and south-eastem mainland Australia and Tasmania, and known larvae feed on fallen leaves. Adults and genitalia of both sexes are figured, and heads, wing venation and other structures if relevant. The larval chaetotaxy is illustrated and the unusual biology is described. A tentative cladogram for the species of Epitymbia is given and the phylogeny of the genus is discussed with a view to clarifying the taxonomic status of the Epitymbiini.
