New data on Microlepidoptera (Lepidoptera: Micropterigidae, Adelidae, Glyphipterigidae, and Yponomeutidae) from the Far East of Russia

A new species Cauchas storozhenkoi sp. nov. (Adelidae) is described from the Far East of Russia. The fauna of Russia was replenished by one genus and one species due to the find of Metanomeuta fulvicrinis Meyrick (Yponomeutidae) in Primorskii Krai for the first time.

The problems associated with the valid designation of the lectotype of M. fulvicrinis and the species composition in the genus Metanomeuta Meyrick are discussed. Kessleria fasciapennela (Yponomeutidae) is first reported from the Far East of Russia. The diagnostic characters of the Micropterix sikhotealinensis Ponomarenko & Beljaev (Micropterigidae) were revised considering the morphology of the female genitalia.

The female genitalia of the Glyphipterix maritima Diakonoff (Glyphipterigidae) is described for the first time. Photographs of adults and genitalia are given for the new species and taxa for which new data were obtained.
