The caddisfly family Hydropsychidae Curtis is revised for the Ryukyu Archipelago, southwestern Japan. Four new species are described based on adults: Diplectrona uken Ito and Nozaki sp. nov., Homoplectra crassicornea Nozaki and Ito sp. nov., Homoplectra trifurcata Nozaki and Ito sp. nov. and Cheumatopsyche aira Ito and Nozaki sp. nov. Based on examination of type specimens of species described from Taiwan in 1910-1930's: Cheumatopsyche uchidai Kobayashi 1987 and Hydropsyche yaeyamensis Tanida 1986 are synonymized with C. clavalis Martynov 1930 and H. orbiculata Ulmer 1911, respectively. Five East Asian species: Diplectrona burha Schmid 1961, Diplectrona albofasciata (Ulmer 1913), Cheumatopsyche clavalis Martynov 1930, Hydropsyche verrucosa (Ulmer 1911), and Macrostemum formosicolum (Matsumura 1931) are recorded from Japan for the first time and re-described. Adults of two known species, Cheumatopsyche okinawa Oláh and Johanson 2008 and Macrostemum okinawanum (Matsumura 1931) are re-described. Females of five species, previously known only as males, are described for the first time.
对日本西南部琉球群岛的长角石蛾科（Hydropsychidae Curtis）进行了修订。基于成虫描述了四个新物种：宇久岛双距石蛾（Diplectrona uken Ito and Nozaki sp. nov.）、粗角同距石蛾（Homoplectra crassicornea Nozaki and Ito sp. nov.）、三叉同距石蛾（Homoplectra trifurcata Nozaki and Ito sp. nov.）和爱良角石蛾（Cheumatopsyche aira Ito and Nozaki sp. nov.）。通过对1910 - 1930年代从台湾描述的物种模式标本的研究：小林长角石蛾（Cheumatopsyche uchidai Kobayashi 1987）和八重山长角石蛾（Hydropsyche yaeyamensis Tanida 1986）分别被认定为与1930年的Martynov的C. clavalis和1911年的Ulmer的H. orbiculata同义。首次记录并重新描述了五个东亚物种：1961年的Schmid的Diplectrona burha、1913年的Ulmer的白带双距石蛾（Diplectrona albofasciata）、1930年的Martynov的C. clavalis、191年的Ulmer的瘤长角石蛾（Hydropsyche verrucosa）和1931年的Matsumura的台湾大茎石蛾（Macrostemum formosicolum）。重新描述了两个已知物种的成虫，2008年的Oláh和Johanson的冲绳长角石蛾（Cheumatopsyche okinawa）以及1931年的Matsumura的冲绳大茎石蛾（Macrostemum okinawanum）。首次描述了五个此前仅知雄性的物种的雌性。
