Wen, Chao, Chen, Fangying & Dai, Wu, 2017, A review of the leafhopper genus Scaphoideus (Hemiptera: Cicadellidae: Deltocephalinae) from Guangxi of China, with description of one new species, Zootaxa 4247 (4), pp. 351-377 : 371-373

Scaphoideus apicalis Li, 1999

( Figs. 3 C, H, M, 16A–G)

Scaphoideus apicalis Li, 1999 [In Cai & Huang, 1999: 334]; Li et al., 2011: 211. Scaphoideus pristiophorus Kamitani & Hayashi, 2013: 527 syn. nov.

Body length (including tegmen): Male 4.6–4.8mm; Female 4.8–5.0mm.

Coloration and structure ( Fig. 3 C, H, M) as in S. bilineus , but forewings with two reflexed cross veins between outer anteapical cell and costal margin, basal reflexed vein basad of outer anteapical cell ( Figs. 3 F).

Male genitalia. Pygofer in lateral view aspect longer than broad, with dorsal margin straight and ventral margin convexly rounded, with two subapical tufts of long macrosetae in addition to scattered macrosetae on apical half. Subgenital plate triangular, as long as 2/3 length of pygofer, more than twice longer than wide at base, sharply pointed apically and slight curved laterally, lateral margin almost straight, with 4-5 macrosetae ventrally at base. Style robust, with preapical lobe very developed, apical process elongate, tapering to apex and curved laterally.

Connective Y-shaped, stem 1.5 times of the lengh of arms; processes 1.5 times as long as connective, serrate at lateral margin near apex, widest at apical 1/4. Aedeagus small, shaft with dorsal and ventral margin almost straight, apex with very small apical hooked processes at dorsal margin; gonopore apical on posterior surface.

Material examined. 1♂, Guangxi, Huaping , 31. viii. 2000, Liu Zhenjiang ; 1♂, Guangxi, Huaping, 31. viii. 2000, Liu Zhenjiang ( NWAFU) .

Distribution. China (Guangxi, Fujian, Sichuan, Guizhou).

Remarks. This species was described from Fujian, China by Li (1999) based on one male and one female specimen. Subsequently , Kamitani & Hayashi described S. pristiophorus from Japan. The illustrations given by Li are not very accurate. Dr. Jichun Xiang (personal communication) confirmed that the male genitalia illustrated here agree with the male genitalia of the holotype . From examination of specimens from China and comparison of the original descriptions and illustrations of S. pristophorus , it is clear that these two taxa are synonyms. This species can be distinguished by the serrate lateral margin of connective process near apex, aedeagal shaft with dorsal and ventral margin almost straight, apex with very small apically hooked processes at dorsal margin.
