Holotype : ♀ , “Formosa, bei Taihorinsho in 1 August , leg. Sauter “ [ China : Taiwan ], Museum für Naturkunde, Berlin , Germany . Paraanthidium ( Orthanthidium ) formosanum : Mavromoustakis, 1953: 837 , ♀ (colour differences). Trachusa ( Orthanthidium ) formosana : Pasteels, 1972: 85 , ♀ (redescription); Kasparek, 2017: 90 , ♀ (redescription). Trachusa ( Orthanthidium ) formosanum : Wu, 2006: 171 , ♀ (redescription), ♂ (new description), Fig. 91. Material examined: China : Guizhou , Jiangkou Xian , Fanjing Shan ( 27º36′N , 108º48′E ), 500 m , 1 ♂ , 14.VIII.1988 , leg. Long-Long YANG ; Guangdong , Nanling , Dadongshan ( 24º46′N , 112º41′E ), 1 ♂ , 24.VI.2009 , leg. Ya-Ping WU , 2 ♀ , 22.VI.2009 , leg. Bo-Wen YU ; Formosa Sauter Fuhosho [Wucheng], IV.1909 , 1 ♂ , 4 ♀ (Budapest, Logan) . General distribution: China ( Guizhou , Fujian , Guangdong *, Taiwan) . Remarks: Kasparek (2017) only redescribed the female because he thought the male was unknown, but Wu (2006) previously described the male. The coloration pattern of the female specimens collected from Guangdong is different in T3–T5 (especially, T3 with one continuous yellow band on disc, not as one narrow yellow stripe each on both sides of the middle line of T3), scutum and scutellum from that of the specimens described and depicted by Kasparek (2017) .
