Taxonomic notes on the Ectoedemia suberis and angulifasciella species groups in Japan (Lepidoptera: Nepticulidae).

Diagnoses and notes on biology and distribution of Japanese species of the suberis and angulifasciella groups of the genus Ectoedemia Busck, 1907 are given. Two species, E. chasanella Puplesis, 1984 and E. ortiva Rociene Stonis, 2013, are reported for the first time from Japan and their morphology is redescribed. In addition, we provide molecular identification of the two species and their relatives based on COI barcode sequences and the nuclear gene (EF1-α) sequences. The female of E. chasanella is described for the first time. We confirm that E. chasanella utilizes Quercus species (Fagaceae) as its hostplant: Q. dentata, Q. serrata, Q. crispula, and Q. acutissima. Ectoedemia ortiva was formerly placed in the suberis group, and its host plant was unknown. We move this species to the angulifasciella group and provide evidence that it utilizes Ulmus sp. (Ulmaceae) as its host plant.

A review of the Japanese species of the family Tischeriidae (Lepidoptera).

This paper provides taxonomic and biological data on one new and one newly recorded species of Coptotriche Walsingham and one new and one newly recorded species of Tischeria Zeller from Japan. Coptotriche symplocosella Kobayashi & Hirowatari, sp. n. (host Symplocos lucida, Symplocaceae), and Tischeria kumatai Sato, Kobayashi & Hirowatari, sp. n. (host Tilia japonica, Malvaceae) are described. The pupal morphology of Coptotriche symplocosella is illustrated with scanning electron micrographs. Coptotriche minuta Diskus & Stonis, 2014 and Tischeria relictana Ermolaev, 1986 are newly recorded from Japan. The female, hostplants (Carpinus, Corylus, and Ostrya species), and immature stages of Coptotriche minuta and the adult features, female, and hostplants (Betula species) of Tischeria relictana are described with photographs and drawings for the first time. Mine types and characters of Japanese Tischeriidae are reviewed with photographs.
