Viraktamath, C. A. & Mohan, G. S., 2004, A revision of the deltocephaline leafhopper genus Scaphoideus (Hemiptera: Cicadellidae) from the Indian subcontinent, Zootaxa 578, pp. 1-48 : 13-15

Scaphoideus bicoloratus sp. nov.

Figs 20–27 .

Head with an anterior marginal transverse band medially connected with a similar band on face chocolate brown, two transverse spots behind it one on either side of median line hyaline, a “flying falcon” ­shaped transverse stripe with a median interruption reddish brown, a spot on hind margin on either side of median line chocolate brown. Face with transverse chocolate brown stripes on frontoclypeus. Gena, clypellus, lorum with chocolate brown patches against ochraceous background. Pronotum chocolate brown with circular hyaline spots and anterior marginal ochraceous area interrupted by chocolate brown. Scutellum with chocolate brown and ochraceous areas. Front wing coloration as in Fig. 20 . Male pygophore and female ovipositor with chocolate brown patches caudally. Legs ochraceous with middle and hind tibiae spotted with chocolate brown, apex of hind tibia, apical 0.33 of hind basitarsus and basal 0.75 of second tarsomere chocolate brown.

Head bluntly angular in front, as wide as pronotum. Vertex as long as inter­ocular width.

Male genitalia: Pygophore longer than high, with two caudal tufts of long setae. Subgenital plate broad basally, abruptly narrowed at 0.33, then of uniform width, 2.5 times as long as basal width, with 4 long setae. Style broad basally, preapical lobe well­developed, apophysis rugulose, apex bidentate. Connective with stem longer than arm, each paraphyses slender, needlelike, crossing over its counterpart at distal 0.25 length. Aedeagus Vshaped, dorsal apodeme well­developed, shaft cylindrical, distal apex curved posteriorly, with a subapical pair of appendages directed ventro­caudlly. Each appendage slightly broadened subapically with crenulated margin, gonopore subapical on caudal margin.

Female genitalia: Seventh sternum about as long as wide, caudal margin medially produced with a median notch.

Measurements: Male 4.0– 4.1 mm long, 1.02 mm wide across eyes. Female 4.5 mm long and 1.20 mm wide across eyes.

Material examined: INDIA: Holotype ɗ, Karnataka: Nagarhole, 1.ii.1983, Shashidhar Coll. ( UAS). Paratypes: 2 Ψ, data as holotype; 1 ɗ, ­ INDIA: Karnataka: 12 Km NE Sandur, 12.ix.1983, Shashidhar Coll. ( BMNH, NPC, UAS).

Remarks: S. bicolorata can be recognised by its coloration. It shares the needlelike paraphyses with S. russus , but it has relatively stouter paraphyses that cross over one another.
