Abstract. Eighteen species in 10 genera of the plant bug subfamily Bryocorinae of Japan are recognized and listed. A new genus, Bryophilocapsus, is proposed to accommodate a unique new species inhabiting thuidiaceous moss in Shikoku. Five new species are described, including one which was erroneously recorded from Japan as Cyrtopeltis geniculata Fieber. hsiaoi Zheng et Liu, Cyrtopeltis rl!fobrllnnea Lee et Kerzhner and Michailocoris chinensis (Hsiao) are reported from Japan for the first time.

Key words: Heteroptera, Miridae. Bryocorinae. new genus. new species. new records. Japan.

Members of undescribed species. this subfamily are considered to be distributed In this paper, a list of Japanese taxa of the predominantly over the tropics and sUbtropics, where Bryocorinae is provided, with distributional records the fauna is still in great need of investigation. The for each species, and brief notes on biology and/or bryocorines are principally host plant specific, and are also given for known species.
