Scaphoideus zhoui Li & Xing, 2011 [In Li et al., 2011: 258].

Body length (including tegmen): Male 5.7–6.4mm; Female 5.9–6.8mm.

Head including eyes slightly narrower than pronotum, produced anteriorly, longer medially than next to eyes, median length slightly longer than width between eyes, about 1.7 x length next to eye. Crown smooth, anterior margin of head mostly shagreen, narrowly rounded to face. Eyes fairly large. Ocelli situated on anterior margin of crown and separate from eye by distance less than ocellar diameter. Frontoclypeus very long and narrow, longer than width between eyes. Antennal pits large, encroaching onto frontoclypeus. Antennal sockets situated above middle of eye. Eyes notched along median margin. Clypellus expanded apically. Lorum wider than clypellus at base. Gena slightly incised below eye. Pronotum as long as head, with anterior margin roundly produced and posterior margin slightly concave. Combined length of mesoscutum and scutellum slightly longer than length of head, suture curved. Forewing semi-transparent, with appendix wide, outer anteapical cell acute apically; inner anteapical cell opened basally; two reflexed cross veins between outer anteapical cell and costal margin.

Ochraceous with well-defined brown or black pattern. Crown margined anteriorly by chocolate brown, with one yellowish round spots on either side of median line posteriorly of anterior margin. Face ochraceous, with transverse chocolate brown stripes on upper part of frontoclypeus. Pronotum ochraceous. Mesoscutum and scutellum yellowish brown, lateral margin chocolate brown, with hyaline spot at each anterior angles of scutum and lateral margin of scutellar suture, one small hyaline spots margined brown one on either side of median line anteriorly on scutum. Forewing with distal two-thirds transparent, basal third brownish with scattered unpigmented spots, bounded posteriorly with dark-brown; remainder of forewing yellowish with darkening in apical margin.

Male genitalia. Pygofer elongate, slightly tapering posteriorly in lateral aspect, with tuft of long macrosetae subapically and scattered short macrosetae on apical half. Subgenital plate elongate, broad basally with lateral margin incurved at basal 1/4, tapered over distal 3/4 to acute apex, four macrosetae ventrolaterally near base. Style preapical lobe distinct with several long setae. Connective long and thin, stem about 3.5 times longer than arm, arms forceps-shaped; connective processes long and thin, each with lateral preapical spine, apex curved dorsad. Aedeagus in ventral view narrowed with obvious median cavity; stem slender and slightly sinuate in lateral view, apex slightly expanded.

Material examined. 1♂ 2♀♀, Hainan, Jianfengling , 4. vi.2007, Duan Yani ; 2♂♂ 8♀♀, Hainan, Jianfengling 20. vii.2009, Gao Xia ; 1♂, Hainan, Jianfengling, 21. vii. 2009, Wang Manqiang ( NWAFU) ; 1♂, Yunnan, Xishuangbanna , 2. vi.1959, Li Suofu (IOZ).

Distribution. China (Guangxi, Hainan, Yunnan).

Remarks. This species was described from Guangxi by Li and Xing (in Li et al., 2011), based on one male and one female specimen deposited in the Institute of Entomology, Guizhou University, China. The original figure of the aedeagus shows the apex acute and recurved dorsally rather than rounded as in the specimen studied here. This species is similar to S. spinulosus Li and Song, but can be distinguished by the ochraceous vertex lacking a transverse band across eyes, and the lateral spine on the connective process.
