Figs 74–80 .

Scaphoideus illustris Rao and Emiliyamma, 1995: 82 –83. HOLOTYPE ɗ, INDIA [ZSI, examined].

Coloration as described by Rao and Emiliayamma (1995). Head narrower than pronotum, angularly produced. Vertex as long as inter­ocular width, shorter than pronotum.

Male genitalia: Pygophore caudally rather truncate, ventral margin slightly convex. Subgenital plate rather triangular, more than three times longer than broad at base, with apical narrow extension, with 4 long marginal setae at basal 0.33. Style short, preapical lobe well­developed, apophysis of style slender, with an apical thin process, surface transversely rugose. Connective with stem longer than arms, paraphyses close together in basal 0.33, then divergent, slightly expanded in distal 0.33, mesal margin in distal 0.3 crenulate, apex rather pointed. Aedeagus with well­developed dorsal apodeme, shaft short, ventrally deeply grooved, with a dorsal keel in basal 0.5, a pair of anteriorly directed pronglike processes at midlength, gonopore subapical.

Female genitalia: Seventh sternum twice as broad as long, caudal margin rather straight.

Measurements: Male 4.40 mm long, 1.07 mm wide across eyes. Female 5.10 mm long and 1.17 mm wide across eyes.

Material examined: INDIA: holotype ɗ, Tamil Nadu: Madumalai, 13.ii.1992, G. Thirumlai Coll. (ZSI). Paratype Ψ, data as holotype (ZSI). Other material: INDIA: Tamil Nadu: 1ɗ, Yercaud, 1370 m, 18.ix.1978, C.A. Viraktamath; 1 Ψ, same data but collected on 20.ix.1978 ( UAS).

Remarks: The apically strongly diverging arms of the paraphyses distinguish this species from other species of Scaphoideus .
