Coloration as described by
Distant (1908b)
with following additional characters. Anterior margin of head with three arched piceous lines one above and two below ocelli. Apex of vertex with a round black spot, a transverse castaneous band connected with apical black spot sometimes medially interrupted by an ochraceous line. Basal triangle of scutellum piceous, area between them orange, posterior half brightyellowish white with piceous lateral marginal spot near apex.
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.

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
” “Myitta, Doherty” “Dist. Coll. 1911383”. The synonymy is based on the similarity of the colour pattern in the two species.
