The <i>Stigmella oxyacanthella</i> species‐group in Europe (Nepticulidae: Lepidoptera)

Abstract

Abstract The Stigmella oxyacanthella species‐group sensu Johansson 1971, is revised here. Ten European species are recognized: torminalis (Wood), regiella (Herrich‐Schäffer), crataegella (Klimesch), hahniella (Wörz), magdalenae (Klimesch), nylandriella (Tengström), oxyacanthella (Stainton), pyri (Glitz), minusculella (Herrich‐Schäffer) and desperatella (Frey). Two species previously attributed to the group are here excluded: aceris (Frey) and aeneella (Heinemann). The latter is synonymized with Stigmella anomalella (Göze). Ten lectotypes are designated and an identification key to all the species is provided. Descriptions of adults and their genitalia and of larvae and their biology are given. The group has a holarctic distribution.
