(Fig. 12)
Diagnosis. Bolivaritettix sanbaishanensis sp.nov. is similar to Bolivaritettix yuanbaoshanensis Zheng et Jiang, 1995, but differs in: antennae inserted below lower margin of eyes; lateral ocelli placed in between lower third of eyes; disc of pronotum slightly convexed between shoulders; disc of pronotum coarsely, with numerous small tubercles; width of midfemur narrower than width of visible part of tegmina. It appears similar to Bolivaritettix sikkinensis (Bolivar, 1909), but differs from the latter by it midkeel of pronotum slightly convex before shoulders; lateral ocelli placed in between lower third of eyes; width of midfemur narrower than width of tegmina.
Description. Female. Size small, slender. Head not exserted above pronotal surface (Fig. 2 b). Vertex 1.5 times wider than width of one eye, anterior margin of vertex straight, not protruding beyond eyes (Fig. 12 c), median carina conspicuous. In profile, vertex and frontal ridge obtuse rounded together (Fig. 12 b), slightly concave before lateral ocelli, frontal ridge roundly protruding between antennae, width of longitudinal furrow narrower than width of first segment of antennae. Antenna filiform, 14-segmented, length of a segment in middle about 6–7 times longer than its width, inserted below lower margin of eyes (Fig. 12 d). Eyes globose; lateral ocelli placed in between lower third of eyes (Fig. 12 d). Disc of pronotum coarsely, with numerous small tubercles, anterior margin of pronotum straight, midkeel of pronotum completed and slightly convex before shoulders in profile. Lateral keels of prozona parallel, humeral angle obtuse, with abbreviated carinae between shoulders. Hind process of pronotum narrow, long cone-shaped, hind process slightly surpassing apex of hind femora (Fig. 12 a, b). Lateral lobes of pronotum produced outwards, end of posterior angles truncated (Fig. 12 a), posterior margins of lateral lobes of pronotum with two concavities (Fig. 12 b). Tegmina long oval, apex rounded. Wings reaching or slightly surpassing top of hind process of pronotum (Fig. 12 b). Anterior and middle femora elongated, margins of middle femora straight (Fig. 12 e), width of midfemur narrower than width of visible part of tegmina. Length of hind femur 3.2 times longer than wide, antegenicular acute and genicular denticles right angle. In dorsal view, outer side of hind tibia with 6–7 spines, inner side with 4–5 spines. Length of first segment of hind tarsi longer than third, three pulvilli equal in length, apices of all pulvilli obtuse (Fig. 12 f). Ovipositor narrow and long, length of upper valvulae 5 times its width, upper and lower valvulae with slender saw-like teeth. Length of subgenital plate equal to its width, posterior margin of subgenital plate with with three teeth (Fig. 12 g).
Body dark brown.
Male. Smaller and narrower than female. Vertex 1.4–1.6 times wider than width of one eye. Width of midfemur equal to width of visible part of tegmina. Length of hind femur 3.0 times longer than wide. Subgenital plate brief cone-shaped, apex sharp (Fig. 12 h). Other structures and coloration same as female.
Measurements. Length of body: 38.5– 9 mm, Ƥ 10.5–11 mm; length of pronotum: 310.5– 11 mm, Ƥ 11.5– 12mm; length of hind femur: 35.5– 6 mm, Ƥ 6–6.5 mm.
