Figs 22, 30 View FIGURES 20 – 31 , 32, 36– 46 View FIGURES 32 – 40 View FIGURES 41 – 46

Green to greenish ochraceous with red tinge.

Vertex with rounded anterior margin between eyes, medially slightly longer than next to eyes. Frons slightly depressed beneath anterior margin with coarse sculpturing. Hind wings milky white. Male abdominal terga 2, 3 and 4 with apodemes ( Figs 38–40 View FIGURES 32 – 40 ). Male eighth sternite widened in distal half, lateral angles of hind margin rounded, caudal margin almost straight with several spines on ventral surface.

Male genitalia: Ventral pygophore process broad in basal 0.33, narrowed and of uniform width in middle 0.33, then broadened gradually and narrowed to pointed apex, apical area with a few longitudinal rugae, dorsal margin of process in some specimens serrated at midlength. Style of type 1. Aedeagus with preatrium well developed, shaft broadest at basal 0.25, then narrowed to apex, ventral margin rather straight, dorsal margin concave, with serrated margin, short rugae, and denticles.

Female genitalia: Hind margin of seventh sternite broader than long, rather rectangular, hind margin slightly produced in middle. Second pair of gonapophysis with smooth area between distal and middle teeth, apex rather broadly rounded, without subapical ventral notch.

Measurements: Male 10.40 mm long (10.30–10.70), 2.55 mm wide across eyes, 3.15 (3.10–3.30) mm wide across hind margin of pronotum. Female 11.40 mm long, 2.70 mm wide across eyes, 3.30 mm wide across hind margin of pronotum.

Material examined: Nepal: Holotype ď, Katmandu, 1978, V.K. Thapa ( UAS). Paratypes: Nepal: 3 ď, 1 Ψ, data as for holotype ( BMNH, IARI, UAS); 3 Ψ, Katmandu, Kokari-Takha, 28.x- 14.xi. 1978, V.K. Thapa ( UAS); 14 ď, 1 Ψ, near Simra, Adhobhar, collected on 25 (6 ď), 27 (4 ď), 28 (4 ď, 1 Ψ), viii. 1967, Canadian Nepal Expedition; 4 ď, 1 Ψ, Katmandu: Godavari, 6000 ’ (1820 m), 15.vii (1 ď), 24.vii (1 ď), 31. vii (1 Ψ), 30.viii (2 ď), 1969, Canadian Nepal Expedition ( CNC). Other material: Nepal: 4 nymphs from Bhartpur, Birganj ( CNC); India: Uttaranchal: 1 ď, Dehradun, 27.iv. 1975, C.A. Viraktamath; West Bengal: 1 Ψ, 8 km E Kalimpong, 1768 m, 29.x. 1981, C.A. Viraktamath ( UAS).

Remarks: K. bakeri   resembles K. strigicollis   but in addition to differences in the male genitalia, it differs in lacking the black spots on the anterior margin of vertex, anterior rim of the head and ocelli are placed a distance more than half own diameter away from the adjacent eye; but in K. strigicollis   they are much closer. The male third sternal apodemes are short and broad whereas in K. strigicollis   they are widely separated, and reach anteriorly the second segment.
