description
Head about as wide as pronotum. Vertex bluntly pointed, longer than interocular distance. Claval veins medially approximated. Male genitalia: Pygophore longer than high, with a few tufts of apical long setae, caudal margin rounded. Subgenital plates triangular, with acute apex, slightly curved laterally with two stout long setae at basal 0.33. Style with welldeveloped preapical lobe, apophysis strongly curved laterally, about half as long as style, with subapical tooth and numerous microscopic denticles on ventral margin, apex acutely pointed. Connective with stem as long as arms, latter semicircular, paraphyses slender, elongate. Aedeagus with stout, cruciform (in cephalic view) dorsal apodeme, shaft slender, strongly curved first caudally then dorsally with a pair of long apical processes, gonopore apical. Female genitalia: Hind margin of seventh sternum medially angularly produced into a lobelike structure with a notch in middle. Measurements: Male 4.50 mm long, 1.08 mm wide across eyes. Female 4.50 mm long, 1.13 mm wide across eyes.
discussion
Remarks: The head pattern and strongly curved aedeagal shaft with an apical pair of processes distinguish this species from other species of Scaphoideus. The type specimen of S. polymitus is missing; however, the label which bore the type reads “ Type, H. T. ” “ Scaphoideus polymitus Dist. type ” “ Myitta, Doherty ” “ Dist. Coll. 1911 383 ”. The synonymy is based on the similarity of the colour pattern in the two species.
