For the diagnosis and detailed description of the adults and genitalia, see Lee et al. (2018).

Distribution.

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).
