A revision of the genus Morophagoides Petersen (Lepidoptera, Tineidae) from Japan.

Taxonomy of the Japanese species of the genus Morophagoides Petersen, 1957 is revised. Previously four species, namely Morophagoides ussuriensis (Caradja, 1920), M. moriutii Robinson, 1986, M. occidentalis Osada, Yoshimatsu, Sakai and Hirowatari, 2014 and M. meridianus Osada, Yoshimatsu, Sakai and Hirowatari, 2014 were recognized for the Japanese fauna. In the present study, four new species, M. breviculus sp. nov., M. robinsoni sp. nov., M. aquilonis sp. nov. and M. yakuensis sp. nov., from Japan are described based on adult characters. The potential synapomorphy of this widely distributed genus is proposed. In addition, the distribution pattern of the genus in Japan is discussed.

Four new species of Gracillariidae (Lepidoptera) from China and Japan, and description of the pupal morphology of the genera Corythoxestis, Eumetriochroa, Guttigera, and Metriochroa.

Four new leaf mining Oecophyllembiinae (Gracillariidae) species are described from China and Japan: Metriochroa symplocosella sp. nov. (host plants: Symplocos anomala, S. sumuntia, Symplocaceae) from China, Guttigera schefflerella sp. nov. (host plant: Schefflera octophylla, Araliaceae), Eumetriochroa araliella sp. nov. (host plants: Dendropanax trifidus, Evodiopanax innovans, Eleutherococcus sciadophylloides and Fatsia japonica, Araliaceae) and Corythoxestis tricalysiella sp. nov. (host plant: Tricalysia dubia, Rubiaceae) from Japan. Corythoxestis sunosei (Kumata, 1998) is recorded from new host plants: Adinapilulifera and Mussaenda parviflora, Rubiaceae, from Japan. The female adult and pupal morphologies, life history and host plant of the genus Guttigera are described for the first time. Pupae of seven species of four genera: Corythoxestis, Eumetriochroa, Guttigera, and Metriochroa, are described for the first time. We provide morphological diagnostic differences between species and genera of Oecophyllembiinae and Phyllocnistis. Our preliminary data suggest that Oecophyllembiinae species have three valuable pupal diagnostic characters: 1) cocoon cutter with unique lateral processes or setae on the clypeus, 2) tergal spines with only a pair of dorsal setae, and 3) cremaster with more than two pairs of caudal processes, while Phyllocnistis species possess 1) cocoon cutter without lateral processes or setae on clypeus, 2) tergal spines with a pair of dorsal setae and dorsal hooks, and 3) cremaster with only a pair of caudal processes.

New record of the genus Stereodytis Meyrick, 1914 (Lepidoptera: Oecophoridae) from Japan with the description of a new species.

A new species Stereodytis eclipsia Tomura & Hirowatari sp. nov. from Japan is described. Images of the imagos, male and female genitalia, larval biology, feeding habits, and molecular data are provided. Additionally, its systematic position and the possibility that this species was invasive in recent years are discussed.

A new species of Nemophora from Korea (Lepidoptera, Adelidae, Adelinae).

A new species of the genus Nemophora Hoffmannsegg, Nemophora lutea Ko & Hirowatari sp. nov. is described from Korea, which is very similar to N. smaragdaspis (Meyrick) found in India and Nepal but distinguished by its the straight deep orange median band and metallic white lines on the forewing in both sexes. Illustrations of adults and genitalia are provided, with habitat information.

Taxonomic study of Palumbina Rondani (Lepidoptera, Gelechiidae, Thiotrichinae) in Japan: biology, immature stages, and a new species.

The genus Palumbina Rondani, 1876 belongs to the family Gelechiidae, which was until recently believed to comprise 26 species worldwide and mainly occurring in the Oriental region. Previously, only P.pylartis (Meyrick, 1908) had been recorded from this genus in Japan. In this study, five other species were identified. Four species were recorded for the first time in Japan, and another was newly described: P.acerosa Lee & Li, 2018; P.grandiunca Lee & Li, 2018; P.macrodelta (Meyrick, 1918), P.operaria (Meyrick, 1918) and P.muraseae Kyaw & Yagi, sp. nov. The host plant and larval feeding habits of P.pylartis, P.acerosa, P.grandiunca, and P.muraseae Kyaw & Yagi, sp. nov. were revealed. The immature stages of P.grandiunca, P.pylartis, and P.muraseae Kyaw & Yagi, sp. nov., including larval and pupal morphology, were first documented for the genus in which the larval chaetotaxy of P.pylartis and P.grandiunca is well observed. In their larval chaetotaxy, the details of their interspecific variation in the relative position and length of some setae are described. The pupal morphology of the species examined in this study is almost identical to the genus Thiotricha except for different traits on the abdominal segments A7 and A10. The traits of larval chaetotaxy and pupal morphology are also discussed for the subfamily. Photographs of the adult, male and female genitalia, and information on their biology and immature stages are provided.

Review of the genus Vespina (Lepidoptera, Incurvariidae) with two new species from China and Japan.

Asian species of the genus Vespina Davis, 1972 (Lepidoptera, Incurvariidae) are mainly reviewed. Vespina meridiana Hirowatari Yagi sp. nov. from the Ryukyu Islands, Japan, and Vespina sichuana Hirowatari, Huang Wang sp. nov. from Sichuan, China, are described. The previously known Vespina species are associated with plants from the Fagaceae family on the western coast of the USA and East Asia and with Sapindaceae (Aceraceae) in eastern Europe. The two new species described here are associated with Fagaceae and Myricaceae, respectively, in warm temperate areas in Asia. Vespina nielseni Kozlov, 1987, which was only known from East Asia, is newly recorded from South China. A checklist for the genus is provided herein. Morphological information of the immature stages of the two new species is partially provided. The absence or reduction of a female frenulum and presence of approximately 20 thin pseudofrenular bristles, the dorsoventrally flattened pupa, and the minute tergal spines scattered on abdominal segments 3-8 are considered as possible autapomorphies of Vespina.

A Taxonomic study of two species of Thiotricha Meyrick (Lepidoptera: Gelechiidae), from southwestern Japan, with notes on the biology of their immature stages.

The taxonomy and biology of the immature stages of two gelechiid species of Thiotricha Meyrick, 1886, found in the southeastern part of the Sino-Japanese region is presented. Thiotricha lumnitzeriella Kyaw, Ueda Hirowatari sp. nov., from islands in southwestern Japan is described. The larva of this species feeds as a portable case maker on Lumnitzera racemosa Willd. (Combretaceae). Thiotricha gemmulans Meyrick, 1931 originally described from India is newly recorded from Japan, mainland China, and Thailand. This species feeds as a portable case maker on Glochidion zeylanicum var. lanceolatum (Hayata) and G. zeylanicum var. zeylanicum (Gaertn.) A. Juss (Phyllanthaceae). Thiotricha acrophantis Meyrick, 1936 is newly synonymized with T. gemmulans. Images of the adults of Thiotricha lumnitzeriella sp. nov. and T. gemmulans including genitalia, and images and illustrations of the larval chaetotaxy and pupa for both species are provided. Larval feeding habits are described in detail.

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.

Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

A part of Japanese species of the genus Thiotricha Meyrick, 1886 are reviewed. Three species described by Omelko (1984) in the genus Cnaphostola Meyrick, 1918 are placed in combination with Thiotricha; Thiotricha biformis, T. angustella comb. nov. and T. venustalis comb. nov. These species are redescribed, and two new species, T. elaeocarpiella Kyaw, Yagi & Hirowatari, sp. nov. and T. flavitermina Kyaw, Yagi & Hirowatari, sp. nov. are described based on external morphological characters of adults and genitalia of males and females. Thiotricha chujaensis (Park, 2016), comb. nov. described in Cnaphostola from Korea, is newly recorded in Japan feeding on Mallotus japonica (Euphorbiaceae). One of the new species, T. elaeocarpiella sp. nov. has been associated with two different plants, Elaeocarpus zollingeri (Elaeocarpaceae) and Rhaphiolepis indica (Rosaceae). This paper presents the first comprehensive description of the morphology, pupal morphology and biology of species previously treated in the genus Cnaphostola and their relatives in Japan.

The following taxonomic synonyms are proposed: P. delicatus Grouvelle, 1908 = P. x-notatus Grouvelle, 1912 syn. nov. = P. nitidior Grouvelle, 1919 syn. nov. = P. raffrayi Grouvelle, 1919 syn. nov.; P. harmandi, Grouvelle, 1912 = P. boreas Yoshida and Hirowatari, 2014 syn. nov.; P. dentatus Grouvelle, 1883 = P. scitus Yoshida and Hirowatari, 2014 syn. nov.; P. simonis Grouvelle, 1892 = P. stultus Grouvelle, 1912 syn. nov. A key to Taiwanese Psammoecus species, a redescription of P. delicatus, and notes on the variability of P. harmandi are provided.

Systematics of Phyllocnistis leaf-mining moths (Lepidoptera, Gracillariidae) feeding on dogwood (Cornus spp.) in Northeast Asia, with the description of three new species.

During an ongoing DNA-barcoding campaign of the leaf-mining moths that feed on woody plants in Northeast Asia, four lineages of the genus Phyllocnistis (Gracillariidae, Phyllocnistinae) were discovered on dogwood (Cornus spp): P. cornella Ermolaev, 1987 on C. controversa Hemsl. (Japan: Hokkaido) and three new species - one feeding on C. controversa, C. florida L. and C. macrophylla Wall. in Japan (Honshu, Shikoku, Kyushu), a second species on C. macrophylla in China (Yunnan) and a third on Siberian dogwood Cornus alba L. in Russia (Siberia). All these species showed differences in morphology, in the barcode region of the cytochrome c oxidase I gene and in two nuclear genes (histone H3 and 28S ribosomal RNA). No correlation was found between the deep mitochondrial splits observed and the Wolbachia infection pattern. Based on both morphological and molecular evidence, the three recently discovered lineages are described here as new species: P. indistincta Kobayashi & Triberti, sp. n. (Japan), P. saepta Kirichenko, Ohshima & Huang, sp. n. (China) and P. verae Kirichenko, Triberti & Lopez-Vaamonde, sp. n. (Russia). In addition, the authors re-describe the adult morphology of P. cornella, provide the first record of this species from Japan and highlight the diagnostic characters that allow these Cornus-feeding Phyllocnistis species to be distinguished.

Review of the genus Roeslerstammia, with a new species from China (Lepidoptera, Roeslerstammiidae).

The new species Roeslerstammia tianpingshanasp. n. is described from Hunan, China as the first record of the genus in the country. Examination of two enigmatic Indian species, R. metaplastica Meyrick, 1921 and R. hemiadelpha Meyrick, 1922, revealed that the latter is a synonym of the former. The male and female genitalia of R. metaplastica are described and illustrated for the first time. A checklist for the genus is given.
