摘要

The species of Siobla Cameron from Taiwan, China are revised. Three new species are described: Siobla foveata Niu and Wei, sp. nov., S. robustiserrula Niu and Wei, sp. nov. and S. tenuitibialis Niu and Wei, sp. nov. Siobla insularis Malaise, 1945 is synonymized with S. taiwanica Malaise, 1945. Siobla straminea immaculata Wei, 2002 and Siobla schedli Haris, 2007 are synonymized with S. maxima Turner, 1920. The female of S. fumipennis Malaise, 1945, the males of S. formosana Takeuchi, 1927 and S. taiwanica Malaise, 1945 are described for the first time. A key to the eight known species of Siobla from Taiwan is provided. S. fulva Takeuchi, 1927, S. formosana Takeuchi, 1927, S. fumipennis Malaise, 1945, S. taiwanica Malaise, 1945 and S. maxima Turner, 1920 are redescribed because the original descriptions of them were brief.
