Description BODY. Brown alternated with yellow green and fuscous. HEAD. Vertex fulvous, with light green margins and median line ( Fig. 4 A). Frons fulvous with two large, black, glossy protuberances between eyes; brown transverse line near middle of orbs and yellowish green central carina, dark brown near frontoclypeal suture; margins black ( Fig. 4 C). Genae fawn with fuscous speckles ( Fig. 4 B). Clypeus dark brown near frontoclypeal suture and central fascia yellowish green ( Fig. 4 C). Eyes fuscous ( Figs 4 A–B). THORAX. Pronotum fulvous with yellowish green median line, two fuscous pits in middle, lateral lobes brown. Mesonotum dark brown, with median line and anterior angles green; lateral area with fuscous speckles ( Fig. 4 A). TEGMEN. Brown with fuscous speckles; longitudinal veins brown; transverse veins green ( Fig. 4 E). HIND WING. Brown, veins fuscescent ( Fig. 4 F). LEGS. Fore and median femora fulvous with fuscous longitudinal fascia laterally and transverse stripe apically; fore and median tibiae fulvous with fuscous transverse stripes respectively at base and apex; hind femur fulvous with fuscous fascia at apex, hind tibiae fulvous, tips of teeth black. Metatibiotarsal formula 2-3+8/8/2. ABDOMEN. Dark brown. MALE GENITALIA. Dorsal phallobase lobe with a short process at apical one-third of lateral margin; lateral lobe turned into a long spiniform process directing caudad and a thick unciform process directing cephalad with apex curved caudad at basal third; ventral lobe narrow and long, weakly wide at middle and narrowing to obtuse and membranous apex; apical margin concave medially ( Fig. 5 D–E). Genital style in lateral view with hind margin distinctly excavated at middle ( Fig. 5 B). Capitulum of style narrowing to obtuse apex directing cephalad with a small blunt tooth in lateral view; in caudal view, lateral teeth thin and falcate ( Fig. 5 B–C). FEMALE GENITALIA. Gonoplac with apical margin strongly convex at dorsal half; disc elevated near base in dorsal view; fork well pigmented ( Fig. 5 J–K). Proximal part of posterior connective lamina of gonapophyses IX slightly convex in lateral view; median field bifurcate at apex in dorsal view ( Fig. 5 G–H). Endogonocoxal process foliate; apex obtuse with thin setae ( Fig. 5 M); endogonocoxal lobe moderately long and weakly concave inward, well sclerotized ( Fig. 5 M). Anterior connective laminae of gonapophysis VIII broad; ventral margin straight, bearing small obtuse tooth near subapex and then concave to apex; apical group with three small teeth, and bearing a tiny tooth in opposite direction of the three teeth; lateral group with five keeled teeth ( Fig. 5 M). Sternum VII with apical margin distinctly arcuately convex at middle ( Fig. 5 L).
