Stictotettix morishimai View in CoL sp. nov.

( Figs. 5–8 View FIGURES 1–8 , 11, 15–17 View FIGURES 9–17 , 27–36 View FIGURES 27–35 View FIGURE 36 )

Head yellowish white, with 3 stripes dorsally orange to red; medial stripe narrowed and lateral stripes broad. Thorax yellowish white; pronotum broadly darkened centrally, infuscate at posterior corners, with 3 oblong markings orange to red, which are obscure medial one and broad lateral ones, with 2 pairs of spots pale brown posterolaterally and near middle of posterior margin; mesonotum infuscate apically. Fore wing greenish yellow, tinged with red anteriorly, spotted irregularly brown to brunneus, with apical cell pale brown; usually in males fore wing with spots much darkened. Abdomen brown dorsally, yellowish white to pale brown ventrally, with pygofer pale brown; male subgenital plate yellowish white, brownish basally; ovipositor slightly darkened.

Head 0.9 times as wide as pronotum; vertex 1.5–1.6 times as wide as dorsal median length, 2.1–2.3 times as long as next to eye, 0.6 times as long as pronotum. Pronotum 1.5–1.6 times as wide as median length, 1.5 times as long as mesonotum. Male abdominal sternal apodemes small and short, not reaching posterior margin of 3rd sternite. Female 7th abdominal sternite rectangular, with posterior margin roundly produced near both corners, shallowly notched near middle. Right 2nd valvula of ovipositor with 10–11 strong teeth dorsally, each bearing 1–3 secondary denticles.

Body length (mean): ♂ 3.4–3.8 mm (3.6 mm); ♀ 3.5–3.9 mm (3.7 mm).

Male genitalia. Pygofer with dorsal process large, strongly curved ventrad in apical half, acute apically. Subgenital plate broad at base, gradually narrowed, with 5–7 macrosetae near middle. Style with basal apodeme as long as apophysis. Connective longer than wide, with anterior margin strongly emarginate, with arm slender. Aedeagus with dorsal apodeme large, 1/3 length of aedeagus; atrium with pair of dorsal processes long and slender, extending dorsally, exceeding apex of shaft, slightly sinuate in lateral view, gradually narrowed in apical 1/3, with pair of ventral processes short, fused basally each other, slightly curved dorsad; shaft long, with long apical part exceeding atrial rim, about as long as half length of aedeagus, ventrally curved subapicad; gonopore apical.

Hayashi leg.

Distribution. Japan (eastern Honshu).

Remarks. This leafhopper is similar to Stictotettix cleyerae sp. nov., but it differs in the following characters: dorsal process of aedeagal atrium exceeding apex of aedeagal shaft distinctly and not expanded laterally, and ventral process of atrium remarkably short; female 7th sternite with caudal margin shallowly notched. Up to the present, the distributional range of this species is confined to eastern Honshu, not overlapping to the range of S. cleyerae sp. nov.
