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.

A revision of the genus Nemapogon Schrank (Lepidoptera, Tineidae) including a stored grain pest, N. granella, from Japan

The Japanese species of the genus Nemapogon Schrank, 1802 (Lepidoptera, Tineidae) are taxonomically revised. In Japan, in the past only Nemapogon granella (Linnaeus, 1758), which is known as a stored grain pest, had been recorded. In the present paper, N. mesoplaca (Meyrick 1919), N. robusta Geadike, 2000 and N. bidentata Xiao & Li, 2010 are newly recorded from Japan. The adult morphology, i.e. wing venation, male and female genitalia of the four Nemapogon species is illustrated. These species are clearly separable not only by the male and female genitalia of the adults but also by the DNA barcodes.

Two new species of the genus Morophagoides (Lepidoptera: Tineidae) closely related to the shiitake fungus moth, M. moriutii, from Japan

Two new species of the genus Morophagoides Petersen from Kyushu and the Kanto regions (Gunma and Tokyo Prefs.) of Honshu, Japan, are described. They have been confused with M. moriutii Robinson, a serious pest of the shiitake mushroom, Lentinula edodes (Berk.) Pegler. The new species are clearly separable not only by the male and female genitalia of adult but also by DNA barcodes.

A review of the genus Montescardia Amsel (Lepidoptera: Tineidae) from Japan, with reference to the genital morphology

The genus Montescardia Amsel is redescribed. Montescardia tessulatellus (Zeller) and M. kurenzovi (Zagulajev) are recorded and redescribed from Japan, with figures of the male and female genitalia. Functional morphology of the male genitalia in M. tessulatellus, the type species of Montescardia, is studied for the first time. The terminology used in the description is clarified taking into account the features of the skeleto‐muscular apparatus of the male genitalia and homologation of genital structures.

A review of the Japanese species of the choragella-group of the genus Morophaga Herrich-Schäffer (Lepidoptera: Tineidae), with description of a new species.

The taxonomy of the Japanese species of the choragella-group of the genus Morophaga is reviewed. Previously, one species, Morophaga fasciculata Robinson, 1986, was recorded from Japan. In the present study, a second species, Morophaga plana, sp. nov., is described based on adult morphological characters.

A review of the Japanese species of the genus Scardia Treitschke (Lepidoptera, Tineidae), with description of a new species.

Taxonomy of the Japanese species of the genus Scardia is reviewed, and a new species, namely Scardia fusca sp. nov., is described based on the adult morphology.

Taxonomic notes on the Japanese species of the sistrata-group of the genus Morophaga Herrich-Shäffer (Lepidoptera: Tineidae), including a pest of Ganoderma lucidum (Polyporales: Ganodermataceae)

Taxonomic notes are provided on the Japanese species of the genus Morophaga: M. iriomotensis Robinson, 1986 and M. formosana Robinson, 1986. They are not reported to be of economic importance in Japan, but in Korea M. formosana is known as a pest of Ganoderma lucidum (Fr.) Karst. Here, the morphology of the female genitalia of M. iriomotensis is described for the first time. Images of adults and their male and female genitalia are given as basic information for pest management.
