Figs. 34–52

Description. Female. Size small. Head not exserted above pronotal surface. Vertex 1.5–1.6 times wider than width of one eye, anterior margin of vertex straight, not protruding beyond eyes, median carina conspicuous. In profile, vertex and frontal ridge round angled, concave before lateral ocelli, frontal ridge roundly protruding between antennae, width of longitudinal furrow narrower than width of 1st segment of antennae. Antennae filiform, 14- segmented, length of the 8th segment about 8–9 times longer than its width, inserted between lower margins of eyes. Eyes globose. Lateral ocelli placed in middle between eyes. Disc of pronotum flat in shoulders,

with numerous concavities and protuberances behind shoulders, anterior margin of pronotum straight, midkeel of pronotum continuous, upper margin of pronotum slightly convex before shoulders and straight behind shoulders looked in profile. Lateral keels of prozona longer and constricted backwards, humeral angle obtuse, with a pair of abbreviated carinae between shoulders. Hind process of pronotum narrow, short and cone-shaped, hind process slightly surpassing apex of hind femora. Lateral lobes of pronotum produced outwards, end of posterior angles truncated, posterior margins of lateral lobes of pronotum with two concavities. Tegmina long oval, apex rounded. Hind wings almost reaching top of hind process of pronotum. Upper and lower margins of fore and mid femora undulated, width of midfemur slightly wider than width of visible part of tegmina. Length of hind femur as 3.1 times as width, upper margin serrulate, antegenicular acute and genicular denticles right angle. In dorsal view, outer side of hind tibia with seven or eight spines, inner side with five or six spines. Length of first segment of hind tarsi longer than third, third pulvillus longer than first and second, apices of all pulvilli obtuse. Ovipositor narrow and long, length of upper valvulae 3.6 times its width, upper and lower valvulae with slender saw-like teeth. Subgenital plate longer than wide, the middle part of posterior margin of subgenital plate triangularly projecting.

Body brown or dark brown. Hind wing yellowish brown. Hind tibia dark brown.

Male. Similar to female but smaller. Vertex 1.3–1.4 times wider than width of one eye, width of midfemur 2 times width of visible part of tegmina. Subgenital plate brief cone-shaped, apex sharp.

Measurements. Length of body ♂ 8.5–9.0 mm, ♀ 9.5–10.0 mm; length of pronotum ♂ 10.0– 10.5 mm, ♀ 11.0– 11.5 mm; length of hind femur ♂ 5.5–6.0 mm, ♀ 6.5–7.0 mm.

Type Material. Holotype: 1♀, 29 July 2012, collected by Wei-An DENG, IZSNU. Paratypes. 7♀♀ 6♂♂, type locality, IZSNU (3♂ 3♀) and SCBHU (4♂ 3♀); 2♀♀ 6♂♂, China, Guangxi, Fangcheng, Fulong (Shiwanshan), 21°51’N – 107°50’E, 750m alt, 9 August 2012, collected by Min-Ping LIN and Li-Liang LIN, IZSNU.

Type locality: China, Guangxi, Fangcheng, Dongzhong (Shiwanshan), 21°40’N, 107°29’E, 550m alt.

Remarks. Bolivaritettix shiwanshanensis Deng & Zheng , sp. nov. is similar to Bolivaritettix pianmaensis Zheng & Ou, 2003 and Bolivaritettix zangnanensis Zheng & Shi, 2009 , but is easily distinguished by morphological characters as shown in Table 2 .

Characters B. pianmaensis B. shiwanshanensis B. zangnanensis Etymology. The new species was named after the type locality, Shiwanshan, Guangxi, China. Distribution. China (Guangxi).
