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 : 11

Scaphoideus asymmetricus sp. nov.

Figs 10–19 .

Head, pronotum, and scutellum pale ochraceous. Head with three chocolate­brown arched bands — two on upper part of face below ocelli and one on vertex. A transverse fascia between eyes on disc of vertex, sanguineous, with an anterior chocolate brown margin, a short transverse spot below antennae and between lower angle of eye and frontal sulcus chocolate brown. A spot on anterior margin of pronotum, an arched fascia on disk of pronotum, two spots at base of scutellum meeting on median line, sanguineous; outer­most margin of pronotum with two chocolate brown lines, proepimeron with an elongate chocolate brown band. front wing brownish with a number of large hyaline areas surrounded by dark brown; an oblique band connecting apex of inner and outer claval veins, apex of clavus, a large spot on costal area near basal 0.33, recurved veins to costa, a large spot on third apical cell, dark brown; entire area of apical cells darker.

Vertex, pronotum, and scutellum slightly polished; vertex obtusely rounded, shorter than width between eyes.

Male genitalia: Pygophore longer than high, dorsal margin strongly sclerotised, caudo­dorsal area acutely angled, ventral margin smoothly curved. Subgenital plate triangular with a narrowed, acute apex, three stout setae arising in an oblique line at basal 0.33. Style with well­developed preapical lobe, apophysis stout at base almost straight, apical half strongly laterally curved with pointed apex. Connective with stem stout, twice as long as arm, paraphyses wide apart, asymmetrically twisted, broad in middle, apically narrowed. Aedeagus short, V­shaped, basal half of shaft stout slender in apical half, with a pair of lateral teeth near middle, dorsal apodeme well­developed, gonopore on ventral margin at midlength. Dorsal connective large, winglike.

Measurements: Male 4.40 mm long, 1.15 mm wide across eyes.

Material examined: INDIA: Holotype ɗ, Karnataka: 27 Km SE of Kollegal, 8.viii.1977, C.A. Viraktamath ( UAS).

Remarks: S. asymmetricus , S. sabourensis , and S. sculptus sp. nov. have similar coloration but are otherwise dissimilar. S. asymmtricus differs from S. curvatus in having a much slender, shorter aedeagus with lateral processes, and the paraphyses are very strongly asymmetrically curved.
