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 : 23

Scaphoideus inequalis sp. nov.

Figs 81–87 .

Coloration similar to S. insignis (Distant) but facial markings different. Face ochraceous, dorsal half with four to five transverse chocolate brown to black bands; a transverse band across face brownish, apical marginal areas chocolate brown. A transverse fascia on pro­ and mesopleura chocolate brown.

Head narrower than pronotum, triangularly produced. Vertex with depressed disc, slightly longer medially than inter­ocular width.

Male genitalia: Pygophore with slightly rounded caudal lobe, inwardly curved on caudo­ventral margin. Subgenital plate triangular, inner margin with an indentation in apical 0.25, 2.72 times as long as wide at base with an oblique row of six stout elongate setae, without narrower apical extension. Style elongate, with well­developed preapical lobe. Apophysis of style slender, as long as rest of style, slightly sinuate, with serrated ventral margin. Connective with arms longer than stem, paraphyses weakly developed, slender, unequal. Aedeagus narrow, tubular, strongly curved, directed caudo­ventrally, shaft with anteriorly directed short process at midlength, apex deeply excavated in form of a U; dorsal apodeme strongly developed as long as shaft, gonopore apical.

Female genitalia: Hind margin of seventh sternum with a deep V­shaped excavation in the middle.

Measurements: Male 6.90–7.10 mm long, 1.50–1.55 mm wide across eyes. Female 7.10 mm long and 1.55 mm across eyes.

Material examined: INDIA: holotype ɗ, Karnataka: 19 Km W Dharwad, grasses, 12.xi. 1991, C.A. Viraktamath ( UAS). Paratypes: INDIA: Karnataka: 1ɗ, data as holotype; 1Ψ, Shimoga, light trap, 1975 ( BMNH).

Remarks: S. inequalis resembles S. insignis externally, but differs in the facial markings. Its male genitalia are similar to those of S. knappi , from which it differs in having slender paraphyses and a tubular curved aedeagal shaft.
