A survey of the saicine assassin bugs of Taiwan (Hemiptera: Heteroptera: Reduviidae)

The assassin bug subfamily Saicinae (Hemiptera: Heteroptera: Reduviidae) of Taiwan is surveyed. Seven species belonging to the genera Gallobelgicus Distant, 1906 and Polytoxus Spinola, 1850 are recognized. Lectotype is designated for Saicafuscovittata Stal, 1860 (currently Polytoxus), a species of doubtful identity until now. The following new synonymies are proposed: Polytoxus fuscovittatus (Stal, 1860) = P. selangorensis Miller, 1940, syn. nov., =P ruficeps Hsiao, 1965, syn. nov. Polytoxus rufinervis ardens Ishikawa & Yano, 2002, stat. nov., is downgraded to a subspecies of P rufinervis Hsiao, 1965. The saicine genera and species occurring in Taiwan are keyed and diagnosed. Distributional data are provided for species occurring in Taiwan and several South and South-East Asian countries (Myanmar, Malaysia, Vietnam. Philippines, India).
