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 : 43-45

Scaphoideus varna sp. nov.

Figs 206–212 .

Vertex yellow with brown angular submarginal band, a median “flying falcon” ­shaped spot with a median yellow marking. Face chocolate­brown, frontoclypeus laterally yellow. Pronotum, scutellum, basal 0.33 of front wings chocolate brown with dispersed hyaline or white markings (similar to bicoloratus , Fig. 20 ), posterior margin of this patch of front wing forming a transverse line. One spot behind eye on pronotum, two pairs of lateral marginal spots to scutellum and apex white. Oblique veins on costa of front wing, veins of apical cells, 0.75 of median and inner cell transparent dark fuscous. Pleura chocolate brown except for white spot on meso­ and metapleura.

Head wider than pronotum, conically produced in front. Vertex as long medially as wide between eyes, a median faint ridge separating lateral depressed compartments.

Male genitalia: Caudal 0.25 of pygophore dark brown, caudally rounded, ventral margin convex. Subgenital plate slender, elongate, 3.6 times longer than greatest width near base, five stout setae in an oblique row near basal 0.25. Style with well­developed preapical lobe, apophysis short with bifid apex. Connective with short arms and long stem; paraphyses slender, longer than connective, apically acuminate. Aedeagus boat­shaped, connected to connective by membranous structure, shaft strongly compressed, bladelike, apex attenuated, strongly ventrally curved, dorsal apodeme well­developed, gonopore at 0.66 length on ventral margin.

Measurements: Male 3.90–4.40 mm long, 1.05–1.12 mm wide across eyes.

Material examined: MYANMAR: holotype ɗ, Bhamo, Birmania, Fea, ix.1885, 169 (the number on a separate blue coloured label) ( MCSG). Paratype: 1ɗ, data as holotype but without the number label and collected vi.1885; 1 specimen (sex? abdomen missing) same data but collected on vi.1986 ( MCSG).

Remarks: Both S. varna and S. bicolorata sp. nov. resemble each other externally and have very distinctive coloration. They also share the compressed aedeagus and the slender elongate needlelike paraphyses. S. varna does not bear any process on the aedeagal shaft whereas bicolorata has a pair of slender, elongate, apical processes.
