Material examined. Holotype (female): Nepal: Prov. Gandaki, nordöstlich Rupa Tal ( Lake Rupa ), elev. 600–700 m (28°10'N, 84°8'E), 23–24.x.1983, leg. S. Ingrisch (Bonn ZFMK). GoogleMaps

Diagnosis. The new species is similar to E. poultoniana , but differs by the female seventh abdominal sternite that has only a very short apical projection that is not covering the base of the subgenital plate and by the shape of the subgenital plate, which has a very wide base and terminates into two long, diverging and upcurved projections while in E. poultoniana it is not widened at base and terminates into two short sub-angular lobes.

Description. Medium large species ( Fig. 9D View FIGURE 9 ). Head: Face ovoid; fastigium verticis about twice as wide as scapus; ocelli indistinct; fastigium frontis separated from fastigium verticis by a very fine suture; a pair of short, weak furrows, starting at internal angle of the antennal scrobae, outline the fastigium frontis; subocular furrows present ( Fig. 5A View FIGURE 5 ). Abdominal tergite three with with two rows of few minute spaced stridulatory pegs (each row 5).

Wings little surpassing hind knees ( Fig. 9D View FIGURE 9 ). Tegmen: Radius with two branches, both forked near tip; media anterior fused in basal area with radius; media posterior absent; cubitus anterior forks before mid-length into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 5 anal veins.

Legs: Fore coxa with a rather large spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large, on mid tibiae comparatively short, ventral spines and one pair of smaller ventral spurs; hind femur with 7 external and 3–4 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine each; with 3 apical spurs on both sides.

Coloration. General color discolored brownish (green when alive); vertex unicolored; disc of pronotum unicolored, hind margin hardly darker. Legs of general color. Face green; eyes red brown; tip of labrum brown; mandibles in basal area and internal side yellowish, towards tip black. Tegmen discolored (probably green) semitransparent with green veins; in apical half of tegmen cells with dark brown flecks; hind wing semi-transparent white to light brownish with brown veins and veinlets; cells with large dark brown spots.

Male unknown.

Female. Seventh abdominal sternite wider than long; apical margin in middle with a short conical process that fits in the base of a medial furrow of the subgenital plate. Subgenital plate at base distinctly wider than preceding sternites; after about basal third strongly constricted but before apex apico-laterally extended into two long cones with subacute tip, apical margin in between concave; central area elevated and with a deep medial furrow from base to apical margin; apical cones pointing latero-dorsad ( Figs. 7 View FIGURE 7 A–B). Base of ovipositor with a flattened protuberance that fits in size the space embraced by a process of the subgenital plate ( Fig. 7A View FIGURE 7 ). Ovipositor upcurved, especially in subbasal area, margins slightly and gradually narrowing towards tip; surface with lateral furrow; with apical widening; tip subacute ( Fig. 9I View FIGURE 9 ).

Measurements (1 female).—body w/wings: 36; body w/o wings: 29; pronotum: 6.5; tegmen: 24; tegmen width: 9; hind femur: 17; antenna: 145; ovipositor: 16 mm.

Etymology. Named after the type locality; noun in apposition.
