Crypsithyris efflexa (Xiao & Li, 2006) is newly recorded from Japan. Photographs of adult specimens and genitalia are given. This species is superficially similar to other Japanese Crypsithyris species, but it is distinguishable by its body coloration and genital morphology.

The larval morphology and ecology of following three species of Hadennia, H. incongruence, H. nakatanii and H. obliqua are reported. The last instar larva of H. obliqua is illustrated for the first time. Their distributions, host plants, emergence of larvae and adults in Gifu Prefecture, Japan are reported.

Adult Stathmopodidae are notable for the presence of verticillbristles on the hind-legs and an unusual resting posture in which the hind-legs are elevated above the substrate. Larval feeding strategies are varied, and include predators and fern-spore-feeders. Currently, 12 genera and 56 species belonging to three subfamilies have been recorded in Japan. This paper provides a contemporary overview of the family in Japan and a key to Japanese subfamilies and genera.

A little-known species, Epermenia uedai Kuroko & Gaedike, 2006 is reported for the first time from Honshu and Hirado Island, Japan by rearing the larvae on the leaves of Pittosporum tobira, a species of Pittosporaceae. This is the first record of its host plant. The females of E. uedai are described for the first time.

The tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), is one of the most important pests of tomato. Its occurrence in Japan was first recognized in 2021, in Kumamoto and Miyazaki prefectures. This study was performed to examined the morphological characteristics of all larval stages of T. absoluta for comparison with other Japanese solanaceous-plant-associated gelechiid moths. Two gelechiid species feed on solanaceous plants in Japan: the potato tuber moth Phthorimaea operculella (Zeller, 1873) and Ergasiola ergasima (Meyrick, 1916). This study showed that all instar larvae of these species can be identified based on the prothoracic shield, and the arrangements of subdorsal (SD) (segments A1-8) and subventral (SV) (segment A2) setae.

Grapholita hyalitis (Meyrick, 1909) is recorded from Shimane Prefecture, Honshu, Japan. The adult specimen and male genitalia are illustrated. This is the first record of the species from Honshu.
