Scaphoideas trimaculatus Wang et Li, sp. nov. (Figs. 1~7) Length (incl. teg.): ♂6.8 mm, ♀7.0~7.2 mm. This species is closely related to Scaphoideus bimaculatus Li et Wang, but differs in the following aspects: body larger; vertex with three black spots: end of aedeagus wih two processes. Holotype ♂, paratypes 4♀♀, Yingjiang (2425N, 9756E), Yunnan Province, 20-Ⅵ-2002, coll. by LI Zi-zhong and YANG Mao-fa. 2. Scaphoideus yingjiangensis Wang et Li, sp. nov. (Figs. 8~13) Length (incl. teg.): ♂4.8~5.0 mm, ♀5.0~5.2 mm. This new species is smilar to Scaphoideus festivus Matsumura in appearance, but can be distinguished from the latter by pygofer side rectangle, paraphyses terminally parallel, aedeagus tongue-shape. Holotyp ♂, paratype 1♂, Yingjing (2425N, 9756E), Yunnan Province, 15-Ⅵ-2002, coll. TIAN Ming-yi, 2♀♀, locality as holotype, 20-Ⅶ-2002, coll. LI Zi-zhong. 3. Scaphoideus windeaedeagus Wang et Li, sp. nov. (Figs. 14~19) Length (incl. teg.): ♂6.0 mm. This new species resembles Scaphoideus bimaculatus Li et Wang, but can be distinguished from the latter by vertex with a inverse T-shaped pale stripe, aedeagus wider, the end of style teeth-like.
