Redescription. Male: Body small-sized and slender. Fastigium of vertex compressed laterally: base of fastigium 1.86 to 2.16 times as wide as scapus. Fastigium verticis narrower than scapus; apex rounded. Eyes globular and protruding outward. Pronotum: pronotal disc raised posteriorly, median carina hardly visible; anterior dorsal margin weakly concave, posterior margin rounded. Lateral lobes triangular; higher than long with secondary tympanum, slightly raised elliptical area of thinner cuticle covering partially thoracic auditory spiracle; humeral sinus weak. Prosternum armed with a pair of spines; mesosternal lobes triangular; metasternal lobes rounded. Thoracic auditory spiracle large, oval, partially hidden under lateral lobe of pronotum, setose on inner edge of spiracle. A weak tubercle is present at mid anterior inner edge of spiracle. Tegmina shorter than hind wings, apex rounded. Wings reaching middle of hind tibia when straightened. Stridulatory file slightly curved with 65 teeth which are evenly arranged, middle teeth are large and gradually decreasing in length at distal end; file gradually narrow at distal end. Legs: All tibia dorsally sulcated. Genicular lobes of fore femora armed by bispinose on inner side and unarmed on outer side; mid genicular lobes armed by a single spine on inner side and bispinose on outer side; hind genicular lobes armed by bispinose on both inner and outer side. Fore coxae armed by an elongate spine. All femora dorsally unarmed. Fore and mid femora ventrally unarmed. Hind femora ventrally armed by a single sub-basal spine on inner margin; 4 small, thick black colored spines arranged on outer margin. Tympanum present on fore tibia bilaterally closed, the opening is directed towards dorsal side with a pair of small pits laterally just below the tympanum. Fore and mid tibiae dorsally unarmed. Fore tibiae ventrally armed by 6 small spines on inner margin; 6 small spines on outer margin. Mid tibiae ventrally armed by 6 small spines on inner margin; 6 small spines on outer margin. Hind tibiae dorsally armed by 29-30 minute to small sized, thick black colored spines on inner margin; 33-34 minute to small-sized, thick black colored spines on outer margin. Hind tibiae ventrally armed by 6 small-sized spines on inner margin; 9 small sized spines on outer margin. Single dorsal pair of spurs and two ventral pairs (inner smaller and outer larger) of spurs present on the apical region of hind tibiae. Tenth abdominal tergite nearly unmodified, median carina present with apical projection, middle area moderately depressed, apical margin broadly rounded. Supra-anal plate triangular with basal groove, apex rounded. Subgenital plate slightly longer than broad; median carina visible at apical half; apical margin with slight median triangular excision; styles small, cylindrical; apex obtuse. Cerci stout, cylindrical, compressed apically on dorsal side; two-third apical half with internal tooth, internal cercal tooth broad and gradually narrow towards apically, apices is provided with a globular apex.

Female: Tenth abdominal tergite with short, triangular median excision, apical margin rounded. Supra-anal plate triangular, apex sub-obtuse. Subgenital plate triangular slightly broader than long, apex with moderately rounded excision. Cerci conical; almost straight. Ovipositor moderately straight, slightly upcurved, dorsal valve longer than ventral; weakly surpassing the wings when straightened; length of ovipositor shorter than hind femur.
