Japan (Honshu, Shikoku, Kyushu, Ryukyu), China, Korea ( Lee and Jeun 2022 ), and Taiwan ( Lee et al. 2018 ). The distribution overlaps that of P. pylartis but tends to be found in the northern regions. Host plant. Quercus myrsinaefolia Blume ( Kuroko 1957 , see the remarks of P. pylartis ), Q. glauca Thunb. (new host record) ( Fagaceae ). Biology. The larval biology is very close to that of P. pylartis except for the host plants. We found young larvae on the host plant Quercus glauca ( Fagaceae ) on Amamioshima Island, behaving as a miner in the midrib of young leaves. This late-instar larva made a portable case by cutting the young leaf into small pieces, mainly around the upper portion (Fig. 11A, B ). The resting posture of the adult is similar to that of stathmopodid species, keeping their hindlegs upwards (Fig. 9B ).
