ジャーナル フリーA new species of the Stathmopoda pedella species group from Japan, S. chalcogramma n. sp. is described. This species was reported in Terada (2016) as two separate unidentified species. It was subsequently found that the specimens in question were conspecific following the examination of additional specimens detailed in this work. The external characteristics of the new species are similar to those of some other members of the species group (S. pedella, S. neohexatyla, S. atridorsalis, S. sericicola, S. centihasta and S. stimulata). The adult external characteristics, wing venation, and male and female genitalia of the new species are illustrated and compared with similar species.

ジャーナル フリーWe found Pleuroptya harutai (Inoue) comprises two different species. The only host plant records so far known for Pl. harutai are in the Sapindaceae, but we found larvae similar to those of Pl. harutai rolling and feeding on the leaves of Styrax obassis (Styracaceae). We also collected larvae from Aesculus turbinata (Sapindaceae), and compared the morphology of adults and mitochondrial DNA sequences with those from S. obassis. Results show that the insects from the two different foodplants constitute separate species. Since the holotype has not been examined, we cannot yet establish which of the two strains is true Pl. harutai. Morphological and molecular differences between the two taxa corresponding to the difference of host plants are provided.

ジャーナル フリーMarking and recapture surveys of Chestnut Tiger, Parantica sita (Kollar, [1844]), that began in 1980 in Kagoshima, southern Kyushu, have spread from all over Japan to Taiwan and southeast China, revealing the actual state of seasonal movements of this butterfly. This butterfly moves north by the southwesterly monsoon from spring to early summer (March to June), lives mainly in temperate forests in midsummer (July-August), and moves south by the northeasterly wind in autumn (September to November). This species passes the winter in various non-diapause stages in warm and subtropical regions. This paper summarizes the outline of the seasonal movements, discusses how the moving habit was developed by the spread of this species to the Japanese Islands, and explores the remaining problems.
