Diagnosis. This species can be distinguished from others in the genus by having the wings reduced to small flaps in both sexes.

Description. Body (Figs. 21–22) very elongate and slender. Colour brown or yellow brown—the colour of dry grass. Frontal shield with moderate subanntenal ridge. Ocelli of both sexes poorly developed. Antennae of male about half the length of prothorax, of female about one third the length of prothorax. Prothorax elongate and slender, metazone of pronotum with dorsolateral carinae which become indistinct anteriorly and posteriorly. Foreleg with coxa distinctly shorter than metazone, femur with claw groove situated at about mid point. Both sexes with wings reduced to small lateral flaps. Abdomen elongate and very slender, supra-anal plate triangular, cerci much reduced in both sexes, not reaching tip of abdomen. Caudal margin of sixth abdominal sternite of female (Fig. 49) extended, forming a scoop like structure. Styli of male elongate, about same length as subgenital plate and twice the length of the cerci.

Male genitalia (Figs. 39–40) with dpr short, very broad and truncate, with short anterior and posterior projections and lateral margin finely cuspulate; pa compact with small blunt shagreened projection posteriorly, medial lobe of vph prominent and curved dorsally, anterior portion of vph narrowed, apr of left phallomere prominent.
