Salka denticulata View in CoL sp. nov.
( Figs. 1 View FIGURES 1 – 8 , 9 View FIGURES 9 – 16 , 17–28 View FIGURES 17 – 28 , 113 View FIGURES 113 – 121 )
Body pale yellow to pale ochreous. Vertex with pentagonal black spot centrally; anteclypeus infuscated. Mesonotum with basal triangles black; fore wing with veins yellow. Abdomen black; male subgenital plates brown basally, gradually darkened toward apex.
Vertex 2.4 times as wide as long at dorsal mid-line; coronal suture indistinct; pronotum 1.9 times as wide as long, nearly as long as mesonotum. Male abdominal sternal apodemes reaching posterior margin of 3rd sternite. Female 7th abdominal sternite pentagonal, with posterior margin rounded, 1.5 times as long as wide. Ovipositor (3rd valvulae) extending slightly beyond pygofer.
Body length (mean): 3, 2.9–3.2 mm (3.1 mm); Ƥ, 3.1–3.2 mm (3.2 mm).
Male genitalia ( Figs. 18–28 View FIGURES 17 – 28 ). Pygofer bearing single macroseta on dorsal margin, tuft of short macrosetae at lower basal angle and numerous scattered short setae, with dorsal and ventral processes; dorsal process curved dorsad near middle, slightly exceeding caudal margin of pygofer, with distinct striations apically; ventral process small, sinuate, tapering at apex. Subgenital plate rounded apically, bearing 4–5 macrosetae. Style elongate, narrowed in basal 1/3; apical extension of apophysis with some minute furrows. Connective U-shaped, with central lobe distinct. Aedeagus strongly bent dorsad near base, slightly narrowed in apical 1/3, with pair of asymmetrical apical processes; longer apical process exceeding basal 1/3 of aedeagal shaft, gently curved ventrad, with tiny denticle throughout length except base; shorter process extending laterally, dentate except basally; preatrium short; gonopore apical on caudal surface.
Type series. Holotype: 3, Higashi-inutabu, Isen, Tokunoshima Is., Ryukyus, Japan, 5. VII. 2007, M. Hayashi et al. Paratypes: [Amami-Oshima Is.] 13, Yamma, Sumiyô, 4. VII. 2005, M. Hayashi et al.; 2Ƥ, Ôdana, Yamato, 6. IV. 2007, M. Hayashi et al.; [Tokunoshima Is.] 13, same date as holotype. The holotype is deposited in the Department of Biology, Faculty of Education, Saitama University, Saitama, Japan.
Distribution. Japan (Ryukyus: Amami-Oshima Is., Tokunoshima Is.).
Remarks. The male genitalia of this new leafhopper are similar to those of S. nigricans ( Matsumura, 1932) described from southern Taiwan (Chiayi), but differ in the following characters: ventral pygofer process short and thin; aedeagus bearing pair of asymmetrical apical processes.
Etymology. The specific name is derived from the configuration of the aedeagal process.
