Figs. 20–33
Description. Female. Body small, slender. Head distinctly protruding above pronotum. Width of vertex slightly narrower than width of one eye (vertex width: eye width ratio = 1: 1.1); anterior margin of vertex arced, not protruding beyond eyes, lateral margins turned backward; median carina conspicuous, with a concavity on both sides of median carina. Vertex and frontal ridge forming a round shape in profile, frontal ridge not concave between lateral ocelli, arc-protruding between antennae, longitudinal furrow equal to width of 1st segment of antennae. Antenna filiform, 14-segmented, inserted between lower margin of eyes, mid segments 6–7 times as long as wide. Eyes globose and protruding above pronotum, lateral ocelli placed on middle of anterior margins of eyes.
Disc of pronotum smooth, granulose, mid keel of pronotum continous, upper margin of pronotum undulating before shoulders and straight behind shoulders in profile. Anterior margin of pronotum straight, slightly concave in middle, lateral keels of prozona slightly constricted backwards, disc of pronotum slightly convex between shoulders, humeral angle rounded, lateral margins of pronotum not constricted backwards behind humeral angle, with abbreviated carinae between shoulders. Posterior process of pronotum narrow, long and cone-shaped, reaching the middle of hind tibia. Lateral lobes of pronotum turned outwards, posterior margin with two concavities, end of hind angle truncate. Visible part of tegmina ovate, apex elliptical. Hind wings developed, surpassing apex of posterior process of pronotum. Lower margins of fore femur and midfemur undulate a bit, midfemur a little bit narrower than tegmen. Hind femur stubby, antegenicular and genicular denticles acute. Outer side of hind tibia with five to six spines, inner side with four to five spines. Length of first segment of posterior tarsus longer than third, third pulvillus longer than first and second, apices of first and second sharp, apices of third right angled. Ovipositor narrow and long, length of upper valvulae 3.0 times its width, upper and lower valvulae with saw-like teeth. Length of subgenital plate longer than wide, posterior margin of subgenital plate arcprotruding.
Body yellowish-brown. Wings black. Fore and middle femora and tibiae each with two dark transverse spots. Lower side of outer part of hind femur black. Hind tibia dark brown, with light brown at base and middle. Male. Unknown.
Measurements. Length of body: ♀ 8.0– 8.5 mm; length of pronotum: ♀ 9.5–10.0 mm; length of hind femur: ♀ 5.0– 5.5 mm.
Holotype 1♀, 28 July 2012, collected by Wei-An DENG, IZSNU. Paratypes: Same data, 2♀♀, collected by Min-Ping LIN and Li-Liang LIN, SCBHU.
Type locality. China, Guangxi, Shangsi (Shiwanshan Mountain), 21°58’N, 107°50’E, 350m alt.
Diagnosis. New species is similar to Mazarredia convexa Deng, Zheng & Wei, 2007 from which it differs in frontal ridge not concave between lateral ocelli (frontal ridge concave between lateral ocelli in M. convexa); disc of pronotum smooth, granulose (disc of pronotum coarsely in M. convexa); lateral margins of pronotum not constricted backwards behind humeral angle (lateral margins of pronotum constricted backwards behind humeral angle in M. convexa); hind wings surpassing apex of posterior process of pronotum (hind wings reaching the caudal end of pronotum in M. convexa); width of midfemur narrower than width of tegmina (width of midfemur wider than width of tegmina in M. convexa); posterior margin of subgenital plate of female arc-protruding (middle of posterior margin of subgenital plate with a triangular convex in M. convexa). It appears similar also to Mazarredia convexaoides Deng & Zheng, sp. nov., but differs from the latter by frontal ridge not concave between lateral ocelli (frontal ridge concave between lateral ocelli in M. convexaoides); posterior process of pronotum reaching middle of hind tibia (posterior process of pronotum reaching apex of hind tibia in M. convexaoides), lateral margins of pronotum not constricted backwards behind humeral angle (constricted backwards behind humeral angle in M. convexaoides); posterior margin of subgenital plate of female arc-protruding (middle of posterior margin of subgenital plate with a triangular convex in M. convexaoides).
Etymology. The new species was named after the type locality, Shiwanshan, Guangxi, China.
Distribution. China (Guangxi).
