A survey of the saicine assassin bugs of Taiwan (Hemiptera: Heteroptera: Reduviidae)
Dávid Rédei, Jing-Fu Tsai
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 Saica fuscovittata Stål, 1860 (currently Polytoxus), a species of doubtful identity until now. The following new synonymies are proposed: Polytoxus fuscovittatus (Stål, 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).
