description: <i>Eugryllacris tiga</i> sp. nov. (迪AEÄffi⁂) <b>Holotype:</b> &amp;female;, China, Yunnan Province, Xishuangbanna Dai Autonomous Prefecture, Gasa County, Dahei Mountain, (21°53’10”N, 100°41’15”E, Alt. 1580), 7-IV-2021, coll. Ce Hui. <b>Paratype:</b> 2&amp;male; 2&amp;female;, same data as in holotype. 2&amp;male;, China, Yunnan Province, Puer City, Folian Mountain, (22°46’40”N, 101°0’10”E, Alt. 1410), 15-VI-2018, coll. Haoran Gao. <b>Description.</b> Medium-large species. Fastigium verticis about 2.5 times wider than scapus (Fig. 1A; Fig. 7 AD). Scapus elongate, shorter than the length of eyes; pedicel and first segment of flagellum combined as long as eyes (Fig. 1A). Eyes elongate and oval, protruding outwards; ocelli indistinct (Fig. 1A). Face smooth; subocular furrows distinct; clypeo-frontal structure contains two distinct black dots, one at each side (Fig. 1A). Anterior margin of pronotum projecting in the middle, posterior margin nearly straight; lateral lobes as long as deep, ventral margin straight (Fig. 1 AB; Fig. 7 AD). Tegmen surpassing hind knees (Fig. 7 AD). R releases RS in mid-length of tegmen, RS forked into three branches near tip; MA fused with R in basal third; MP absent; CuA with a single branch that forks between basal third and mid-length into two veins, CuA1 and CuA2; CuP undivided, free throughout; with five Anal veins (Fig. 1D; Fig. 7 AD). Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore tibiae ventrally with 5 pairs of large spines, basal area of internal spines each with a black dot; mid tibiae ventrally with 5 pairs of spines, dorsally with an internal apical spur, basal area of external spines each with a black dot but lighter than those of fore tibiae; hind femora ventrally with 3-7 external and 3-6 internal spinules; hind tibiae dorsally with 5-6 external and 5-7 internal spines and a pair of apical spurs, ventrally with 2 preapical spines and an apical spur on both sides. Female. Seventh abdominal sternite of normal size, posterior margin with a slight concave (Fig. 1F). Subgenital plate in basal area rather wide, gradually narrows with shallow triangular concave at margin and broad obtuse tip (Fig. 1F). Ovipositor long and slightly upcurved, reach to hind tarsus when stretched (Fig. 1G). Male. Ninth abdominal tergite downcurved in apical area, descending in posterior area and split into two hemiglobular regions; two black coarse granular oval contact at the splitting midline. Terminal of each split region contains a rod-like projection which concaves up towards mediad without overlapping. Subgenital plate about twice as wide as long, lateral margin slightly converging. Posterior margin with a medial obtuse-trangularly concave. Styli insert laterally at posterior margin. (Fig. 1E) <b>Coloration.</b> General color green when alive. Face overall unicolored, green when alive; base area of mandible pink and transits into black in inner and tip area when alive; clypeo-frontal suture white, contains a distinct black dot. Disc of pronotum green when alive, with two distinct black dots on each side. Tegmen semi-transparent with green veins when alive; cells at basal area dark brown; hind wings semi-transparent with brown veins and veinlets, cells with large dark brown maculae. Legs of general color; fore and mid tibia spines yellow; fore tibia internal spines and mid tibia external spines with distinct black dots at basal area; hind femora spines black; hind tibia spines yellowish green with black tips; all tarsus orangish yellow. Abdomen yellowish green. Ovipositor brown when alive. <b>Measurements (mm).</b> Body (from head to tip of abdomen): 26.6–35.3; pronotum: 6.5–7.0; tegmen: 29.1–31.5; fore femur: 8.9–10.3; median femur: 9.1–10.0; hind femur: 16.1–16.9; fore tibia: 10.8–11.0; median tibia: 10.7–11.0; hind tibia: 15.6–16.7; ovipositor: 22.5. <b>Natural history.</b> <i>E. tiga</i> is univoltine. Hatchlings emerge generally around July to September and reach adulthood in around April to June the next year. Female adults were observed to lay eggs into wet rotten wood in lab (Fig. 10B). Eggs undergo a hatching period about 50 days before hatchlings emerge (Fig. 11C). Larger nymphs and adults show threat behavior when facing stimulus, with parts of the labrum hides under clypeus showing the jagged mandibles (Fig. 2 BD). <b>Notes.</b> <i>E. tiga</i> is unique, can be recognized by the distinct black dots on legs and pronotum. This species is also characterized by the pair of rod-like projections on terminal of male 9 th abdominal tergite and a concave on female 7 th abdominal sternite. <b>Etymology.</b> This species is named after Ultraman Tiga, a character in the famous tokusatsu television series <i>Ultraman</i>. Species from genus <i>Eugryllacris</i> are always referred to as “Ultraman katydid” among katydid enthusiasts in China. They get this nickname because of their representative yellowish or reddish eyes. According to the <i>Ultraman</i> series, Tiga is the mysterious giant that wakes up from his petrified body and protects human beings. 2021 is the 25 th anniversary of Tiga debuting, so we name this new species as Tiga in memory of the widely welcomed TV series <i>Ultraman Tiga</i>. <b>Distribution.</b> Yunnan, China. Known only from the type locality.
