Maxilla of orthopteroid type, sparsely covered with setae; maxillary palp five-segmented, green, palpomeres two to five covered with setae, palpomere one and two short, nearly as wide as long, palpomere three 2.5 times longer than wide, palpomere four and five ca. twice as long as wide. Labial palp three segmented, green. Scape and pedicel bright green. Scape conical, at base as long as wide. Pedicle half as wide as scape, twice as long as wide. Flagellum yellow-greenish; nearly as long as the entire animal; 25 flagellomeres. Thorax (Fig. 14): compact. Bright green; thin meso-dorsal brown stripe that ends in the anterior third of metanotum; lateral edges of all three nota with thick brown stripe; lateral margin of nota white; pleurae bright green with reddish areas. Completely covered with setae; brown spots where setae emerge along entire thorax. Pronotum nearly squared; overlapping head and mesonotum. Mesonotum not as wide as pronotum, nearly squared. Metanotum narrower than mesonotum; narrowing posteriorly. Coxae large. Legs: bright green. Completely covered with setae; brown spots where setae emerge. Prothoracic leg more massive than meso- and metathoracic leg. Tarsus with 5 brownish tarsomeres; proximal four with euplantulae; large arolium present. Wings: completely absent. Abdomen: shorter than thorax: enlarging posteriorly; completely covered with setae. Bright green; lateral brown longitudinal stripes on tergites.

Male terminalia (Fig. 15): tergum IX bright green, lateral brown stripe; ca. same length as tergum VIII; postero-ventral border rounded. Tergum X bright green; lateral brown longitudinal stripes; roof-shaped in lateral view. Subgenital plate (sternite IX) green; broadly emarginated dorsally; process of subgenital plate broad; dorsal part horizontal in posterior view. Cerci one segmented; green; densely covered with setae; diameter mesally oval; uniformly curved; dorsal projection of cercus very prominent and located at two-third of length of cercus; cerci extending towards middle of subgenital plate.
