Fig. 193–197 View FIGURES 193 – 205 .

Scaphoideus stigmaticus Distant, 1918: 67 View in CoL . HOLOTYPE Ψ, INDIA [BMNH, examined].

Coloration as described by Distant (1918). The median two spindleshaped elongate spots on vertex broader, remaining four on either side of these of similar width, sometimes reaching hind margin of vertex. Upper part of face with an arched dark brown line. Scutellum with median brown stripes in addition to dark brown basal triangles.

Male genitalia: Caudodorsal lobe of pygophore rather triangular, with two tufts of long setae, dorsal margin angularly excavated. Subgenital plate triangular, apex rounded with a few stout setae arranged submarginally. Connective Yshaped. Style with apophysis stout and long, exceeding subgenital plate, ventral margin transversely rugulose. Aedeagus large, compressed, with a pair of subapical processes directed cephaloventrad, a pair of apical processes curved anteriorly after traversing a short distance in line with shaft, gonopore on caudal margin between bases of apical processes; dorsal apodeme welldeveloped.

Female genitalia: Hind margin medially concave, without a median lobe.

Measurements: Male 5.30 mm long, 1.25 mm wide across eyes. Female 5.80 mm long 1.40 mm wide across eyes.

Material examined: INDIA: Holotype Ψ, “ Type, H.T.” (red margined circular disc) “ Scaphoideus stigmaticus Dist. type ” (hand written label) “E. Himalayas” (hand written label) “Distant Coll. 1911383” (printed label), here designated ( BMNH); Assam: 1ɗ, Margherita, W. Doherty from Indian Mus. Distant Coll. B. M. 1911383 ( BMNH); 1Ψ, Sikkim: Singtam, 30.x.1981, C.A. Viraktamath ( UAS).

Remarks: The male specimen was dissected earlier and it is likely that the paraphyses are missing(?). The aedeagus has both apical and subapical long processes. The species is only tentatively retained in the genus pending availability of more male specimens for a proper generic placement. For further comments see S. assamensis .
