We discovered adults and eggs of a lycaenid species, Acytolepis puspa, at the University of Tokyo, the Kanto district, which is located far away from the northeastern limit of the species, the west area of the Tokai district. The eggs were found on Quercus phillyraeoides (Fagaceae). This is the first record of the species in the Kanto district. For the purpose of clarifying the dispersal pathway of A. puspa, we initially examined the adult morphology and the genetic variation of this species from Japan (including Tokyo) and the Oriental region. As a result, the wing markings and genetic structure of the species from Tokyo were the same as those from the mainland of Japan, and this subspecies was identified as A.p. ishigakiana. Second, we surveyed all possible hostplants of the species in the university, and found that two Rhododendron plants (Ericaceae) had been recently transplanted from Suzuka City, Mie Pref., which is very close to the known distribution limit for the species. The northern limit of the distribution of A. puspa in Mie Pref. must have reached Suzuka City, due to its spread of the distribution range by recent global warming. Most Probably, immatures of the species have been introduced from Suzuka to Tokyo, with the transplantation of Rhododendron plants.
