Five genera are Sciences, Kyungpook National University, recognized in the Korean fauna: Diostrombus Uhler, 1896, Losbanosia Muir, 1917, Daegu 702 701, Korea. Pamendanga Distant, 1906, Shirakiana Metcalf, 1945, Zoraida Kirkaldy, 1900. Email: [email protected] Among them, the genus Shirakiana is recorded for the first time in Korea. Nine species, four of which are recognized new to Korea: S. infumata (Matsumura), Received 29 January 2012; Z. koannania Matsumura, Z. hubeiensis Chou et Huang, and Z. kuwayamae (Mat- accepted 19 July 2012. sumura).

Later, Kwon and Huh (2001) provided a revised checklist including one more Materials and methods species, Zoraida albicans Anufriev, 1968, that belongs to this tribe from Korea and then no further work was done. The terminology used in this study follows Yang and Wu The aim of this study, therefore, is to provide a taxonomic (1993) and Zelazny and Webb (2011).
