Scaphoideus kumamotonis Matsumura, 1914: 224 .

Description. Coloration & external morphology. Head slightly narrower than pronotum and strongly produced angularly, pale yellow with very small black spot at apex, pair of small black spots near ocelli; medial length of vertex 1.2 times as long as length next to eyes and 0.6 times as long as width of head; ocelli pale; frontoclypeus pale yellow with 2 transverse narrow brownish stripes near anterior margin, sometimes with only one stripe; clypellus, gena and lorum pale yellow and immaculate. Pronotum 2.1 times as wide as long, slightly longer than mesonotum; pronotum and mesonotum pale brown with wide longitudinal pale stripe weakly darkened laterally. Fore wing pale yellowish semitransparent; ventral surface of thorax, legs and abdominal segments pale yellow. Caudal margin of female 7th abdominal sternite strongly produced caudally and weakly dentate medially.

Male genitalia. Pygofer very long and tapered 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 triangular, as long as half length of pygofer, provided with uniseriate row of 2–3 macrosetae subbasally. Style small, with short apodeme; preapical lobe small and weakly angular; apophysis (apical process) short, roundly curved laterally, sinuate at inner margin, with 2–3 short hairs. Connective with pair of very long processes; processes widest at apical half and pointed apically; arms nearly parallel. Aedeagus slender; shaft 1.5 times as long as basal apodeme, usually with pair of long apical processes (sometimes two pairs, subapical one short and arising from dorsal surface); apical process linear, as long as half length of shaft, turning ventrad; subapical process directing parallel to shaft, half as long as apical process; gonopore apical on dorsal surface.

Body length (mean). ♂, 4.1–4.6 mm (4.3 mm); ♀, 4.4–5.1 mm (4.8 mm).

Distribution. Japan (Honshu, Kyushu, Tsushima Is.).

Remarks. This species is similar to S. albovittatus Matsumura , but is clearly distinguished by the following taxonomic characters: aedeagus elongate with apical processes directed dorsally; style very small; processes on connective widest at apical half and without serration on outer margin. A record of S. kumamotonis Matsumura from the Ryukyus (Hayashi 2002) is a misidentification of S. ryukyuensis sp. nov. (described below).

Scaphoideus ryukyuensis sp. nov. ( Figs. 3 , 23–29 )

Scaphoideus kumamotonis: Hayashi 2002: 103 (nec Matsumura 1914).

Description. Coloration & external morphology. Head slightly narrower than pronotum and strongly produced angularly; medial length of vertex 1.3 times as long as length next to eyes and half as long as width of head, pale yellow with small black spot at apex, pair of large black spots near apex of anterior margin and pair of large black spots near ocelli; ocelli situated on boundary between vertex and frons, pale; coronal suture on posterior surface of vertex indistinct; frontoclypeus pale yellow with a few transverse blackish stripes near anterior margin; clypellus and lorum pale yellow and immaculate; gena pale yellow with a small blackish spot below antenna. Pronotum 2.2 times as wide as long, nearly as long as mesonotum mid-dorsally; pronotum and mesonotum brown with wide longitudinal pale stripe darkened laterally. Fore wing pale yellowish semitransparent; ventral surface of thorax, legs and abdominal segments pale yellow. Caudal margin of female 7th abdominal sternite bisinuate; central part strongly produced.

Male genitalia. Pygofer very long and gradually tapered apically in lateral view, with a tuft of very long macrosetae apically (missing in this figured specimen) and a few shorter macrosetae subapically, without pygofer process. Subgenital plate triangular and long, but as long as half length of pygofer, provided with uniseriate row of 3 macrosetae near base. Style robust, with short apodeme; preapical lobe rounded and wide; apophysis (apical process) rather short, weakly curved laterally, with 3 short hairs. Connective with pair of slender processes; processes as long as 2/3 length of connective, gradually tapered and pointed apically; arms short, roundly curved, widened in lateral view. Aedeagus slender; shaft 2 times as long as basal apodeme, with pair of processes and pair of subapical processes arising from dorsal surface; apical process sinuate, slightly widened, as long as 1/4 length of shaft, directing ventrally; subapical process slender, extending parallel to shaft, slightly shorter than apical process; gonopore apical on posterior surface.

Distribution. Japan (Ryukyus: Okinawa Is.).

Remarks. This new species is very similar to S. kumamotonis Matsumura and S. maai Kitbamroong et Freytag in habitus, but it is easily distinguishable from the latter by the structure of male genitalia: narrow processes of connective, large style and aedeagus with apical processes directed ventrally. The species name is derived from the locality of the types.
