Scaphoideus hirsutus sp. nov.

Figs 64–73 .

Coloration similar to that in S. coloratus . Ochraceous. With a submarginal band on vertex and a series of three transverse stripes on face below ocelli chocolate brown; a transverse band across eyes castaneous, slightly produced medially and marked with chocolate brown; median sulcus on vertex chocolate brown; hind margin of transverse band with three concave excavations, one in the middle, one on either side, ochraceous. Pronotum with an anterior and a submarginal faint castaneous transverse bands, extreme lateral margin fuscous. Basal triangles of scutellum castaneous, two spots on lateral margin fuscous, rest yellowish. Pleura and legs ochraceous with fuscous spots; apices of fore tibiae, first two tarsomeres, and middle leg, bases of spines on hind tibiae and apex of hind tibia, dark fuscous. Front wing with prominent dark brown venation, clavus with fuscous spot at apices of claval veins and apex, a few patches on clavus and apical area of front wing fuscous. Head narrower than pronotum, outer anteapical cell half as long as median.

Male genitalia: Pygophore longer than high, with subapical row of tufts of setae. Tenth segment with ventrally directed process which articulates with aedeagus. Subgenital plate triangular with rounded apex and sub­marginal row of stout setae and long numerous hairlike setae arising from 0.66 apical margin and from apex, both on dorsal and ventral surface, their length longer than that of plate. Style elongate, with well­developed preapical lobe, apophysis stout with transverse striae, 0.4 times length of style, slightly directed laterally. Connective with arms much shorter than stem, paraphyses fused at base, apical 0.33 bifid, curved dorsally in lateral aspect and pointed near apex. Aedeagus simple, shaft in lateral aspect broader near gonopore; with a subapical toothlike process; dorsal apodeme well­developed, gonopore large on caudal margin.

Measurements: Male 5.30 – 5.9 mm long and 1.20 mm wide across eyes.

Material examined: INDIA: Holotype ɗ, West Bengal: Gopaldhara B.W., Darjeeling, 4720 ft (1433 m), 7.v.1917 [original number 14 is struck off and corrected as 17], H. Stevens. Paratypes: 1 specimen (abdomen missing) data as in holotype but collected on ix.1917; 3ɗ, Assam: Margherita, W. Doherty, Ind. Mus. Distant Coll. B.M. 1911­383 bearing numbers 87740/8, 9144/8 and 9442/8 ( BMNH).

Remarks: The apophysis of the style in the paratype male is much longer and more slender and the aedeagal shaft is also slightly longer than in the holotype male. S. hirsutus has the coloration of the species of Scaphotettix . It is unique in having numerous long (almost twice as long as the subgenital plate) hairlike setae on the submarginal plate, to which the specific name alludes. It shares the basally fused paraphyses with S. insignis but differs in colour and, male genital structure and is also a smaller species.
