Coloration. General color yellow green to yellow brown ( Fig. 7 ). Vertex and pronotum pale yellow green ( Figs 18–19 ). Frons dark brown in basal 2/3, yellow in apical 1/3, with scores of pale verrucae along base and lateral margin ( Fig. 20 ). Compound eyes ochreous, ocelli pale green ( Fig. 19 ). Clypeus yellow brown ( Fig. 20 ). Mesonotum yellow brown ( Fig. 18 ). Forewings yellow green, with diffusely dark brownish ( Figs 7–8 ). Hindwings brown. Legs pale green or yellow brown, tip of spines on hind tibiae and tarsi black. Head and Thorax . Vertex shorter in middle than the width (0.54: 1.00) ( Fig. 18 ). Frons ( Fig. 20 ) slightly shorter in middle than the maximum breadth (0.93: 1.00), with median carina and lateral carina reaching to basal 1/3. Clypeus with stout median carina ( Fig. 20 ). Pronotum ( Fig. 18 ) with median carina slim. Mesonotum ( Fig. 18 ) with median carina obvious. Forewings ( Fig. 21 ) longer than width (2.42: 1.00), ScP and RP convergent near base, ScP long, exceeding middle of forewing, MP two branched in basal 1/3, MP 1 dividing three branches in distal 1/3, CuA forked into two branches behind middle of forewing, CuP present, Pcu and A 1 uniting in basal 2/3 of clavus, clavus almost 5/6 of forewing. Hindwings ( Fig. 22 ) with one transverse vein between Pcu+A 1 and anal suture. Hind tibia with 2 lateral spines and 6–7 apical spines, first metatarsomere with 6–7 apical spines, second metatarsomere with 2 spines. Male genitalia. Anal tube longer in middle than the widest breath (2.73: 1.00) in dorsal view, anterior margin slightly arched convex, lateral margin not parallel, the maximum width in middle of anal tube ( Fig. 24 ). Anal style ( Fig. 24 ) located in basal 2/5, relatively long and stout, surpassing the end of anal pore, not surpassing anal tube. Pygofer ( Fig. 23 ) irregularly rectangular, anterior margin and posterior margin nearly paralleled in lateral view, posterior margin with obviously triangular process in dorsal part 1/3, dorsal margin narrow, ventral margin broad. Gonostyli ( Fig. 25 ) irregularly triangular in lateral view, dorsal margin and ventral margin not parallel, dorsal margin straight, ventral margin slightly arched, with small sheet prominence ( Fig. 25a ) in tumefied protuberance ( Fig. 25b ) near dorsal margin at base of capitulum. Capitulum of gonostyli irregularly rectangular, with small angular, neck stout and unobvious ( Fig. 26 ). Phallobase ( Figs 27–28 ) with dorsal lobe slightly expanded in apical part, the middle part expanded to lobe-liked ( Fig. 27c ), lateral lobe splitting into two branches, ventral lobe shorter than lateral lobe in lateral view; ventral lobe with apical part leaf-liked ( Fig. 28d ), the base narrow and claviform in ventral view. Aedeagus ( Figs 27–28 ) with one long hooked process ( Fig. 27e ) in lateral view, directing to cephalad. Female genitalia. Anal tube ( Fig. 32 ) longer in middle line than the width (3.30: 1.00), apical margin arched convex, lateral margin nearly paralleled, the base relatively broad, tapering to apex. Anal style ( Fig. 32 ) located in basal 1/8 of anal tube, short, not surpassing the end of anal pore. Anterior connective lamina of gonapophyses VIII ( Fig. 33 ) irregularly rectangular, bearing 4–5 keels in lateral group and 3 teeth in apical group, apical teeth small, and with one small tooth in ventral margin ( Fig. 33 : vt). Posterior connective lamina of gonapophyses IX ( Figs 34– 35 ) sub-triangular, relatively narrow, lateral field membraneous with microvilli ( Fig. 34 : lf); sub-lateral field with angular process near base ( Fig. 34 : slf); median field with asymmetric prominence (medial dorsal process) ( Fig. 34 : mdp); distal parts bent at acute angled in dorsal view (posterior ventral lobes) ( Fig. 34 : pvb). Gonoplacs ( Fig. 36 ) irregular triangular, without keels, apical part membraneous. Hind margin of sternite VII with obtusely convex near medial area in ventral view ( Fig. 37 ). FIGURES 28–37.
