﻿AbstractFrom the Japanese Archipelago, 12Habrolomaand 20Trachysspecies (Buprestidae:Tracheini) have been recorded. Two newHabrolomaspecies were found, which are associated withElaeocarpaceaeandLoranthaceae, also new host plant families/orders forTracheini. The two new species are described asHabrolomaelaeocarpusisp. nov.andHabrolomataxillusisp. nov., and the latter is the firstTracheinispecies shown to be associated with epiphytes. Leaf mines of 31Tracheinispecies are also reported in this work, including new records of leaf mines for 16Tracheinispecies. The larvae of all these recorded species are full-depth linear-blotch mesophyll miners of mature leaves and pupate within their mines. The mining habits ofHabrolomaspecies associated withSymplocos(Symplocaceae) are unique: the young larvae bore into midribs and petioles and cause leaf fall, and the larvae then mine the fallen leaves.
