description: <i>Eucriotettix tridentatus</i> sp. nov. (Figures 1–3) <i>Male</i> (Figures 1A,B, 2A,B). Size small. Head exerted above pronotal surface (Figures 1A, 2B, 3B). Anterior margin of vertex slightly concave, not protruding beyond eyes, median carina conspicuous. Vertex very narrow, width of one eye 1.2 times width of vertex (Figures 2A, 3A,D); vertex and frontal ridge not visible in profile (Figure 3B). Frontal ridge slightly protruding between antennae (Figure 3B), width of longitudinal furrow narrower than width of first segment of antennae (Figure 3C). Antenna filiform, 15-segmented, inserted between lower margin of eyes, mid segments five to six times as long as wide (Figure 3A,C). Eyes elevated above the pronotum (Figures 2B, 3B), globular in shape, lateral ocelli placed between the middle of eyes (Figure 3C). Disc of pronotum with numerous small granules, mid keel of pronotum entire, upper margin of pronotum straight in profile (Figures 1A,B, 2A,B). Anterior margin of pronotum straight, slightly concave in middle, lateral keels of prozona parallel (Figures 1B, 2A, 3D), humeral angle arched, with abbreviated carinae (Figures 1B, 2A, 3D), flat between shoulders. posterior process of pronotum narrow, long coneshaped, reaching half to two-thirds of hind tibia (Figures 1A,B, 2A,B). Lateral lobes of pronotum turning outwards, posterior angles pointing obliquely backwards, apex of posterior angles horned (Figures 2A, 3D,F) (some individual with short spines), posterior margin of each lateral lobe with two concavities (Figures 2B, 3B). Visible part of tegmina ovate (Figure 3E), apex rounded. Hind wings developed, almost reaching the apex of posterior process of pronotum (Figures 1A, 2B). Upper and lower margins of fore femur and mid femur straight (Figures 2B, 3G,H), width of mid femur narrower than width of tegmina (Figure 3E). Hind femur three times as long as wide, mid keel of dorsal and ventral side of hindfemur dentate, antegenicular and genicular denticles right angle (Figure 3I). Outer side of hind tibia with six to eight spines, inner side with four to five spines (Figure 3J). Length of first segment of posterior tarsus longer than third, three pulvilli equal in length, apices of all pulvilli obtuse (Figure 3K). Subgenital plate brief cone-shaped, apex sharp (Figure 3L,M). Body reddish-brown or yellow brown. Wings black. Fore femur and mid femur dark brown or black. Hind femur brown, hind tibia dark brown. <i>Female</i> (Figure 1C,D). Similar to male, but slightly larger. Ovipositor narrow and long, length of upper valvulae 4.7 times its width, upper and lower valvulae with slender saw-like teeth (Figure 3N). Length of subgenital plate equal to wide, posterior margin of subgenital plate with three teeth (Figures 2C, 3O). <i>Measurements</i> Length of body &amp;male; 7.5–9.0 mm, &amp;female; 9.5–11.0 mm; length of pronotum &amp;male; 9.5–12.5 mm, &amp;female; 12.5–14.0 mm; length of hind femur &amp;male; 5.0–6.0 mm, &amp;female; 6.5–7.0 mm. Holotype male and allotype female, China, Guizhou, Dushan, Zilinshan, 25.8° N, 107.5° E, 900 m altitude, 3 October 2012, collected by Wei-An DENG, IZSNU. Paratypes: Same data, seven male; four females, collected by Wei-An DENG and Shi-Zhen WEI, IZSNU (3&amp;male; 2&amp;female;), SCBHU (4&amp;male; 2&amp;female;). <i>Diagnosis</i> <i>Eucriotettix tridentatus</i> sp. nov. is similar to <i>Eucriotettix brachynotus</i> Zheng and Jiang 1997 and <i>Eucriotettix longipennis</i> Deng et al. 2007. The main differences are listed in Table 2. <i>Etymology</i> The species name is derived from Latin <i>tri</i> and <i>dentatus</i>, meaning posterior margin of subgenital plate of female with three teeth. <i>Distribution</i> China (Guizhou).
