Webb, M. D. & Viraktamath, C. A., 2007, Three new Old World species of the leafhopper genus Scaphoideus Uhler (Hemiptera: Auchenorrhyncha: Cicadellidae), Zootaxa 1457 (1), pp. 49-55 : 51-52

Scaphoideus unimaculatus sp. nov.

( Figs 13, 14 , 17 )

Length: ♂, 4.7–4.9 mm (x 3 specimens); ♀, 5.0–5.2 mm (x 2 specimens)

Yellow marked with orange on vertex and disc of pronotum and scutellum; two incomplete transverse narrow bands on face dorsally coalescing to form a diamond-shaped mark. Forewing with a small brown spot in third apical cell.

External features as in S. dellagiustinai ( Figs 1–3 ). Head relatively narrow in dorsal view with vertex slightly longer than basal width; fore margin of the head truncate in lateral view; clypeus narrow dorsally and antennae situated relatively high on face. Forewing with two recurved costal veins from outer subapical cell.

Male pygofer, subgenital plate and connective as in S. dellagiustinai ( Figs 5, 8, 9 ): pygofer without processes, broadly rounded apically in lateral view with a group of very long setae apically and a few shorter setae subapically. Subgenital plate distinctly shorter than pygofer, broad basally with distal two thirds very narrow in ventral view; a uniseriate row of macrosetae subbasally and a few short fine setae distally. Connective with a pair of slender paraphyses, each paraphysis tapering distally. Style as in S. rubroguttatus ( Fig. 12 ). Aedeagus disassociated from connective; shaft elongate, as long as basal apodeme, with a pair of elongate apical processes and a dorsal serrated flange basally on each side, gonopore apical on posterior surface; basal apodeme compressed anteroposteriorly, bifurcate apically and produced into a lobe on each side at midlength ( Figs 13–14 ).

Female pygofer in lateral view with tufts of very long macrosetae apically, shorter setae centrally and a uniseriate row subbasally adjacent to valvulae; pregenital sternite with posterior margin more or less straight.

Material examined. Holotype ♂, UGANDA: Kawanda, nr Kampala, Buganda , m. v. trap , 6.x.1957 . Paratypes. UGANDA: 3♂, same data as holotype ; 2♀, Kamwezi, Kigezi, 5000’, short grass in valley, 9.viii.1957; 1♀, Kuwanda, 28.vi.1957, at light (all P.E.S. & E.M. Whalley, BMNH) .

Remarks. This species is similar to S. dellagiustinai , S. rubroguttatus and S. quangtriensis but can be distinguished by the dark mark dorsally on the face and the longer apical aedeagal processes.
