Scaphoideus rubrogutattus Matsumura, 1914: 223 .

Description. Coloration & external morphology. Head as wide as pronotum; vertex roundly prominent, pale yellow with transverse orange band between ocelli; medial length of vertex 1.2 times as long as length next to eyes and half as long as width of head; frontoclypeus yellow with a narrow blackish stripe near anterior margin (sometimes absent in female); clypellus, gena and lorum pale yellow and immaculate; ocellocular area with blackish marking above antenna (sometimes absent in female). Pronotum 2.1 times as wide as long, slightly longer than mesonotum, with obscure longitudinal pale stripe and a orange marking near anterior margin; mesonotum with obscure longitudinal pale stripe and pair of longitudinal orange stripes medially. Fore wing yellowish semitransparent; ventral surface of thorax, legs and abdominal segments pale yellow. Caudal margin of female 7th abdominal sternite nearly straight, without incision at middle.

Male genitalia. Pygofer long and slightly truncate apically in lateral view, with a tuft of very long macrosetae apically (missing in this specimen figured) and many shorter macrosetae subapically, without pygofer process. Subgenital plate distinctly widened basally, as long as half length of pygofer, provided with a uniseriate row of 4 macrosetae subbasally. Style robust; preapical lobe very small; apophysis (apical process) short and wide, immediately tapered at apical 1/5, with 3 short hairs. Connective with pair of slightly short processes; processes half as long as connective, gradually tapered; arms somewhat apart to each other. Aedeagus slender; shaft slightly longer than basal apodeme, with pair of short apical ventral processes curved laterodorsad and short apical dorsal process, and with a triangular flange on each basal side of shaft slight curved dorsally; basal apodeme widened at apical 1/3; gonopore subapical on ventral surface.

Body length (mean). ♂, 3.6–5.1 mm (4.6 mm); ♀, 4.4–5.8 mm (5.1 mm).

Distribution. Japan (Honshu, Kyushu, Ryukyus); Taiwan.

Remarks. In the drawing of the male genitalia by Okada (1977), the dorsal apodeme is not shown, possibly due to improper dissection. The base of the aedeagal shaft of Okada’s drawing is somewhat wider than those of other Japanese specimens including the specimens examined by Webb & Viraktamath (2007). This leafhopper is similar to S. quangtriensis Webb et Viraktamath from Vietnam and the Philippines, but differs in the shape of the apical processes of the aedeagal shaft.
