This paper describes four new species of genus Scaphoideus from Yunnan Province, China. The type specimens are deposited in the Institute of Entomology, Guizhou University.1 Scaphoideus shovelaedeagus sp. nov. (Figs.1-7)Body length (incl. tegm.): ♂4.9?mm, ♀5.0?mm. Vertex with median length longer than distance between eyes, anterior margin broadly rounded in dorsal aspect; ocelli located on anterior margin of vertex, near eyes. Vertex pale yellow, its middle area with a broadly yellow transverse stripe, along the anterior margin of crown with a black marginal line. Basal area of face with five black transverse lines. Forewings amber with black patterns, veins black, with 4 apical cells and 3 subapical cells, appendix wide. This species is related to Scaphopideus festivus Matsumura in appearance, but can be distinguished from the latter by the pronotum with two black spots, subgenital plate awl-shaped and the end of aedeagus shovel-shaped.Holotype ♂, Pianma (26°05′N, 98°45′E), Yunnan Province, 13 Aug.2006, coll. by SONG Qiong-Zhang. Paratype 1♀, same data as holotype.Etymology. The specific name is derived from the shovel-shaped aedeagus.2 Scaphoideus spinulosus sp. nov.(Figs.8-13)Body length (incl. tegm.): ♂6.1?mm. General appearance same as the previous species. Its vertex with acutely pointed margin, antennae very long. Vertex pale, along the anterior margin with a black marginal line, its anterior area with W-shaped orange stripe. Basal area of face with two brown transverse lines.This species is similar to Scaphoideus conicaplateus Li et Dai in appearance, but can be distinguished from latter by: 1) anterior area of vertex with a W-shaped orange stripe; 2) antennae very long; 3)aedeagus with spine-shaped.Holotype ♂, Pianma (26°05′N, 98°45′E), Yunnan Province, 13 Aug.2006, coll. by SONG Qiong-Zhang.Etymology. The specific name is derived from the spine-shaphed aedeagus.3 Scaphoideus curvatureus sp. nov.(Figs.14-20)Body length (incl. tegm.): ♂5.5?mm. General appearance as in Scaphoideus shovelaedeagus. Vertex milk, with a broadly orange transverse stripe in middle area. Basal area of face with two brown transverse lines.This species is similar to Scaphoideus curvanus Li et Wang, but can be distinguished from the latter by: 1) vertex and pronotum milk; 2) the basal area of face with brown transverse lines; 3) the distinctly different shape of the genitalia. Holotype♂, Pianma (26°05′N, 98°45′E), Yunnan Province, 13 Aug.2006, coll. by SONG Qiong-Zhang.Etymology.The species is named after Latin curvatura, referring the curved aedeagus.4 Scaphoideus biprocessus sp. nov.(Figs.21-27)Body length (incl. tegm.): ♂5.5-5.8?mm. General appearance as in Scaphoideus shovelaedeagus. Vertex milk, with a black marginal line along anterior margin of vertex, and with a broadly orange transverse stripe in middle area. Basal area of face with three black transverse lines.This species is similar to Scaphoideus conicaplateus Li et Dai in appearance, but can be distinguished from latter by: 1) along anterior margin of vertex with a black marginal line; 2)the end margin of pygofer side like-sawtooth ;3) the end of aedeagus with two processes.Holotype ♂, Jianchuan (26°40′N, 99°50′E), Yunnan Province, 9 Aug. 2006, coll. by SONG Qiong-Zhang. Paratype 1♂, same data as holotype.Etymology. The species is named after Latin bi-plus process, referring the aedeagus with two processes.
