Paratypes: 3 females India, Uttarakhand, Chamoli, Valley of Flowers National Park , 30.70638°N, 79.59547°E, 3216m., 22.X.2017, on grass (collected by H. Kumar) GoogleMaps ; 3 males, 23.X.2017, on grass (collected by H. Kumar).

Male ( Figs. 1A, 1C View FIGURE 1 ). Small sized. Body cylindrical. Antennae ( Fig. 2A View FIGURE 2 ) filiform, as long as or slightly shorter than head and pronotum together; 22 segmented. Head obtusely rounded in profile ( Fig. 2C View FIGURE 2 ), almost smooth, shorter than pronotum. Fastigial foveolae ( Fig. 2I View FIGURE 2 ) long and narrow. Fastigium of vertex ( Fig. 2A View FIGURE 2 ) obtusely angular, slightly depressed, wider than long, without median carinula, slightly lower than vertex. Vertex ( Fig. 2A View FIGURE 2 ) without any carina. Frontal ridge ( Fig. 2E View FIGURE 2 ) impressed, wide, slightly depressed below median ocellus; margins are slightly diverging downwards from median ocellus. Frontal ridge between antennal sockets narrower than vertex between eyes. Eyes situated in middle of head. Maximum length of one eye greater than interocular distance. Frons oblique ( Fig. 2C View FIGURE 2 ). Pronotum ( Fig. 2A View FIGURE 2 ) tectiform, posterior margin straight without median incision, median and lateral carina well developed, median carina straight while lateral carinae incurved in middle of prozona and excurved in metazona, dorsum of pronotum crossed by only posterior transverse sulcus, prozona longer than metazona. Prosternal process absent. Mesosternal lobes ( Fig. 2G View FIGURE 2 ) rounded and inter-space wider than long, margins diverging, metasternal lobes rounded and separate. Elytra ( Fig. 2C View FIGURE 2 ) scale like, lateral, reaching posterior margin of third abdominal tergite. Hind wing vestigial. Hind femur elongated, slightly surpassing apex of abdomen, both upper and lower carina smooth, lower basal lobe shorter than the upper one, lower basal lobe rounded, inner side with a row of stridulatory pegs. Hind tibiae shorter than hind femur, cylindrical with nine external and nine internal spines, external apical spine of hind tibiae absent, inner pair of the spur subequal and slightly longer than external one. Arolium small. Abdomen subcylindrical, with a median dorsal ridge.

Genitalia. Supra-anal plate ( Figs. 2K View FIGURE 2 , 3A View FIGURE 3 ) broadly triangular, lateral margins slightly incurved before apex forming a triangular apical bulb, wider than long, apex obtuse angular; cerci ( Fig. 2L View FIGURE 2 ) short and cylindrical with rounded apex, shorter than supra-anal plate, slightly less than three times longer than wide. Subgenital plate ( Fig. 3B View FIGURE 3 ) pyramidal, apex blunt with median concavity, wider than long. Epiphallus ( Fig. 3C View FIGURE 3 ) with bridge narrow and straight, undivided medially, ancorae small, curved with obtuse apex, lophi bilobate, inner lophi large and elongated ovoid while outer lophi small and bean shaped.Aedeagus ( Fig. 3D View FIGURE 3 ) flexured, apical valve narrow, curved with acute apex; narrower and shorter than basal valve; connected with basal valve by a flexure; basal valve broad, narrowing towards its acute apex; gonopore process large with truncated apex.

Female ( Figs. 1B, 1D View FIGURE 1 ). Larger in size. Antennae ( Fig. 2B View FIGURE 2 ) shorter than head and pronotum together. Elytra ( Fig. 2D View FIGURE 2 ) reaching posterior margin of first abdominal tergite. Hind femur never reaching the apex of abdomen.

Genitalia. Supra-anal plate ( Figs. 2M View FIGURE 2 , 3E View FIGURE 3 ) broadly angular, slightly wider than long with obtuse apex; cercus short, narrow and conical, shorter than supra-anal plate, more than twice as long as wide, with rounded apex. Subgenital plate ( Figs. 2N View FIGURE 2 , 3F View FIGURE 3 ) elongate with median longitudinal furrow in its entire length, posterior margin broadly rounded with median projection, without setae; egg-guide conical, longer than wide, with rounded apex. Spermatheca ( Fig. 3G View FIGURE 3 ), apical diverticulum narrow with rounded apex, much narrower and slightly shorter than pre-apical diverticulum, pre-apical diverticulum broad and tubular. Ovipositor valves ( Figs. 2O View FIGURE 2 ) short, moderately robust, curved, dorsal valve broad, more than three times as long as wide, shorter than lateral apodeme, apical tip curved and obtuse, external edge smooth; ventral valve narrow with rounded external, lateral projection, apical tip curved and obtuse; medial valve dilated apically, apical tip truncated.

Coloration: General colour reddish-brown. Antennae becoming darker in apical half. Hind femora red ventrally, knees black. Hind tibiae red; hind tibial spines with black tips. Abdomen with a black stripe on each side.
