Description. In addition to the characters of the genus: Male. Medium-size (24–25 mm.). Coloration. Body predominantly dark and reddish brown ( Fig. 1 ); cephalic capsule dark brown with black stripes on the vertex, face and mandibles; area surrounding the ocelli, mandibles, lower margin of clypeus and labrum ochre; ocelli yellow; eyes purple; palpi brown with some ochre stripes; fore and mid legs dark brown, femora with diffuse yellow-brown stripes from the base to apex; hind legs dark brown with a yellow stripe on the femur from the base to mesal section, through the chevrons ( Figs. 2A–C ). Pronotum brown with some reddish spots, anterior and posterior margins of pronotal disc delineated in ochre, ventral margin reddish and delineated ( Fig. 3C ). Sternun yellow; tegmina reddish-brown, abdomen light brown with several dark brown spots. Head round, conspicuous, smooth, and shiny; maxillary palpi mid-sized, third and fourth subequal and cylindrical, the fifth flattened, dilated from the middle to the apex, and distally curved ( Figs. 2A–C ). Left mandible has a basal mid-sized projection or horn placed on the clypeus ( Figs. 2A, C ). Wings ovoid, reaching to the sixth tergite, harp, and mirror without veins, c1, c2, and c3 slightly differentiate, and with some cross-veins, giving a reticulated appearance to the three cells ( Fig. 2D ); lateral field with four longitudinal veins. Legs. Coxae well developed, rectangular shaped, laterally compressed, margins rounded, dorsal inner margin with a small tubercle. Fore tibia with a small and ovoid tympanum on both sides; hind tibia dorsally serrulate, with four dorsal spurs on both margins placed on second half of the total length of the tibia.

Abdomen. Last segments unmodified. Epiproct covered by many bristles, and with mid grove from the base to apex ( Fig. 2E ). Cerci almost as long as the fore and mid tibiae, covered by abundant medium-sized bristles. Subgenital plate rectangular, longer than wide, posterior margin concave ( Figs. 2F ). Male genitalia. Ps. p2. elongated and spatula-shaped with the posterior and lateral outer edges slightly curved upwards ( Figs. 3A, C, D ); ps. p1. short, rounded, and slightly raised ( Figs. 3A, C ); A. scl. wider than long, arising from the middle of ps. p1, 2 ( Fig. 3C ); ps. s. thin and angled in its middle length, connecting with the A-, B. scl. ( Figs. 2A, C, D ); arc. connecting with the ec. s. and pseudepiphallic parameres ( Figs. 3A–B ).

Female. Unknown.
