Diagnosis. This species can be recognized by the following characters; body densely spotted; head as long as pronotum (female); abdominal cerci short, stout, 8-segmented.

Description. Female body ( Figs. 1, 2 ) straw-coloured, slender, grass-like, densely black-spotted.

Head ( Figs. 3, 4 ) elongated, lance-shaped. Juxta-ocular lobes prolonged, separated by median suture along entire length; apex split and twisted, right juxta-ocular lobe longer and darker than left one. Vertex triangular, vertically with pale median groove, lower end with two black ocellus-like structures on both sides of groove. Eyes oblong, laterally placed. Ocelli minute. Lower frons trapezoidal, vertically with two carinae and one groove in middle. Clypeus with median carina and small notch on both sides. Antennae highly ciliated.

Pronotum long, slender, as long as head, with nearly parallel lateral margins ( Fig. 1 ). Supra-coxal dilation indistinct. Metazona about 1.5 times as long as prozona. Prosternum with median black ridge and two lateral grooves. Mesothorax and metathorax both dorsally and ventrally with two black spots on either side of each segment. Wingless. Metathoracic ear very narrow.

Prothoracic legs ( Figs. 5, 6 ) with coxa shorter than metazona. Upper, lower and lateral edges with spinules and highly ciliated towards base. Upper half of coxa dorsally smoky. Coxal lobes convergent, superior lobe with one black patch anteriorly. Trochanter dorsally with one black spot. Disc of femora granulated, with median ridge. Femora with sharp genicular spine; four posteroventral spines, bases dorsally with semi-circular black lines and spines decreasing in length towards apex except fourth one; 4 discoidal spines and 19 anteroventral spines (8 long and 11 short), both long and short spines gradually shortened towards apex, all spines brown at apex only.

Left side (dorsal view) of anterior process of left phallomere (afa) with a separate thick sclerotized sheath with many closely arranged small bristles facing downward. Ventral phallomere slightly elongated; posterior edge curved, distal edge with minute spines and with a small, straight, triangular, sharp distal process (sdp). Right phallomere with somewhat cylindrical pva distally with multiple strongly sclerotized minute spines; pia curved, highly sclerotized thin line with two weak creases in middle.
