Diagnosis. Head having longest projection of vertex approximately two times longer than compound eye length, slightly posterior oriented ( Figs. 1B View FIGURE 1 , 2A View FIGURE 2 ). Tegmina with long and wide light-yellow stripe at costal section, reaching from base to apex; having long and wide black stripe at radial-medial section, reaching approximately 2/3 of wing; cubital and anal sections dark-brown, with light-yellow veins; keel of tegmina slightly undulated, with apical-most projection slender ( Figs. 1A–B View FIGURE 1 , 2B–C View FIGURE 2 ). Costal area of posterior wing with anterior half with stripe conspicuously light-yellow. Sternite VII 1.6 times longer than wide, with broad aspect ( Figs. 1B, D View FIGURE 1 ). From mesosternum onwards dark-brown with several light-yellow spots ( Fig 1C View FIGURE 1 ). Subgenital plate (sternite VIII) with apical margin narrowing, abruptly projecting medially; projection arched; medial elevation weakly marked, two times longer than wide at widest point ( Fig. 2F View FIGURE 2 ).

Description ♀ (only known sex). General coloration dark-brown, same as when specimen was alive. Head. With several scattered granules; dorsally with paired rows of six orange projections, with the longest approximately two times the length of compound eye, slightly posteriorly oriented ( Fig. 2A View FIGURE 2 ). Gena with wide black stripe and thin orange stripe behind compound eye ( Fig. 2A View FIGURE 2 ). Vertex medially dark-brown, laterally light yellow. Antenna setose, mainly anteriorly dark-brown, posteriorly light-brown; from flagellomere 14 onwards with orange stains ( Fig. 1B View FIGURE 1 ). Compound eye light-orange with dark-brown spots ( Fig. 2A View FIGURE 2 ).

Thorax. Thorax with several setae near pleural margin. Pronotum with paired parallel longitudinal stripes and paired parallel rows of three projections. Mesonotum dorsally with paired parallel rows of five projections; four of these projections’ orange; with several scattered granules. Pro- and mesosternum smooth, dark-brown with some orange spots, with few scattered granules ( Fig. 1C View FIGURE 1 ). Metasternum dark-brown with black spots ( Fig 1C View FIGURE 1 ).

Legs. All legs covered by minute light-yellow setae. Anterior femur dorsally 1.2 times longer than mesonotum, dark-brown with several minute light-yellow spots ( Fig. 1B View FIGURE 1 ); ventrally dark-brown with light-brown spots. Anterior tibia and tarsus dark-brown with few light-yellow stains ( Figs. 1A–D View FIGURE 1 ). Mid and posterior idem ( Figs. 1A–D View FIGURE 1 ).

Wings. Tegmina with long and wide light-yellow stripe at costal margin from, reaching from base to apex; with long and wide black stripe at radial-medial section, reaching approximately 2/3 of the wing; cubital and anal sections dark-brown, with light-yellow and dark-brown veins ( Figs. 1A–B View FIGURE 1 , 2B–C View FIGURE 2 ); keel of tegmina slightly undulated, with apical-most projection slender ( Figs. 1A–B View FIGURE 1 , 2B–C View FIGURE 2 ). Costal area of posterior wing with anterior half with conspicuous light-yellow stripe; anal area greyish, tessellated ( Figs. 1B, D View FIGURE 1 ).

Abdomen. Tergites and sternites longer than wide, with few scattered light-yellow and black spots. Sternites parallel sided, densely covered by inconspicuous setae. Sternite II 1.8 times longer than wide ( Fig. 1C View FIGURE 1 ). Sternite VI two times longer than wide ( Fig. 1C View FIGURE 1 ). Sternite VII 1.6 times longer than wide, with broad aspect ( Fig. 1C View FIGURE 1 ). Subgenital plate (sternite VIII) dark-brown, with several light-yellow spots, lateral margin nearly straight; apical margin narrowing gradually, then abruptly projecting medially; apex arched; medial elevation weakly marked, two times longer than widest point ( Fig. 1C View FIGURE 1 , 2F View FIGURE 2 ). Gonapophysis 8 flattened, ellipsoid ( Fig. 2F View FIGURE 2 ). Gonapophysis 9 with nearly same length of gonapophysis 8; elongated, conspicuously curved at setose posterior half ( Fig. 2F View FIGURE 2 ). Paraproct long and wide, dorsoventrally flattened ( Fig. 2F View FIGURE 2 ). Cercus laterally flattened, slightly narrowing at middle length, densely covered by long setae.

Measurements (mm). Total body length (dorsally measured, from base of frons to tip of abdomen, excluding cercus): 79.5; anterior femur (dorsally measured): 10; length of tergites VII–X combined (laterally measured): 8; cercus: 2.2.
