(Plate I; Fig. 1 –6)

Material examined. (02 Specimens, 2♀). Paratype: India: Manipur; 25.viii.2014, Coll. Yeshwanth, H. M., (Chandel) (1) Ex. Bamboo;24o19’–464’ N Longitude, 93o59’–212’ E Latitude 893m MSL.

Description. Body large, cylindrical, macropterous, frons flat to weakly convex, oblique, smooth; lateral carinae absent. Fastigium of frons separated from fastigium of vertex by small, poorly defined gap; fastigium of vertex triangular, apex rounded, shorter than half of scapus. Eyes globular, moderately protruding; median ocellus present, circular; antennal scapus unarmed; antennae about twice as long as body. Pronotum with surface smooth; anterior margin of pronotum concave, flat; metazona flat to strongly carinate, posterior edge of metazona straight to weakly rounded; lateral lobe more than twice as long as high; humeral sinus of pronotum absent; posterior margin of pronotum concave. Thoracic auditory spiracle narrowly oval, completely hidden under pronotum. Sternum slightly concave; prosternum armed with two long spines; mesosternum posterior lobes slightly extended into oblique, short, triangular processes; metasternum posterior lobes with small protuberances. Front coxa armed with short spine; front femur weakly compressed laterally, armed on both ventral margins; genicular lobes of front and mid femur with no spine on anterior (inner) side only; hind femur armed with single spine on both sides; tympanum bilaterally closed, with narrow, forward facing slits; 7 internal; 8 external ventral spines on front tibia from about half as long to as long as tibia diameter. Fore femur spines 1-2 ventroexternal, 0-3 ventrointernal;mid femur unarmed on both ventral margins;hind femur 9 ventroexternal, 4 ventrointeral; 6 apical spur; hind tibia spines 12 dorsoexternal, 15 dorsointernal, 9-11ventroexternal, 7-7ventrointernal; genicular lobes of mid femur armed on posterior (inner) side only; mid tibia unarmed dorsally. Hind femur armed on anterior (outer) ventral margin only; genicular lobes of; hind tibia armed on both dorsal and ventral margins.Tegmen nearly fully developed and reaching apex of abdomen to strongly reduced, Costal field not dilated at base; tegminal venation normally developed to reduced; right stridulatory area with large, fully developed mirror; mirror roughly rectangular to nearly round. Stridulatory file flat, straight. Hind wing fully developed to extremely reduced.

Female:Tenth tergite with two strongly developed posterior lobes; Cerci conical at base, suddenly narrowing apically, apex obtuse, pointed and hairy. Subgenital plate weakly sclerotized in its central portion, lateral edges of plate with two pairs of small sclerites; posterior margin with shallow, edges triangular rounded. Ovipositor about as long as hind femur; compressed blade shaped; slightly curved, apex with both valve smooth, dorsal edge of upper valve parallel to lower valve; apex pointed.

Colouration: General colour light brown, Pronotum with diffuse, dark stripe, continuous with that on abdomen. Legs light brown, irregular, abdominal terga with dark, central stripe, brown or straw coloured when alive, Dorsum of head and pronotum with nearly wide brown stripe, light lateral border, head light brownish, brown including the fastigium, frons, clypeus, gena and scapus, apex of maxillary and labial palpi brown and yellowish, mouthparts yellowish or brown. Frons occeli shining white. Antennae pale light brown, annulated, first two segments blackish. Anterior legs generally brown or straw coloured, anterior tibial tympanum yellowish brown. Tegmen appears light brown when live, but is hyaline with veins and veinlets brown with black spots; femora of all legs with genicular lobe brown, spines with black tip, hind femur at apex with back marking. Cerci brown, prosternum, meso- and metasternum yellowish with brown. Spines on all legs with apex black/brown, tarsal segment ends with black marking. Legs with various shades of brown.
