Figs. 1–19
Description. Female. Body small, slender. Head distinctly protruding above pronotum. Width of vertex equal to width of one eye; anterior margin of vertex straight, 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 rounded in profile, frontal ridge distinctly concave between lateral ocelli, arc-protruding between antennae, longitudinal furrow narrower than width of 1st segment of antennae. Antennae filiform, 15-segmented, inserted between lower margin of eyes, mid segments 5–6 times as long as wide. Eyes globose and protruding above pronotum, lateral ocelli placed a little bit below the middle of anterior margins of eyes.
Disc of pronotum coarse, granulose, mid keel of pronotum continuous, upper margin of pronotum undulate before shoulders and straight behind shoulders looked from profile. Anterior margin of pronotum straight, slightly concave in the middle, lateral keels of prozona constricted backwards, angled, disc of pronotum slightly convex between shoulders, humeral angle rounded, lateral margins of pronotum constricted backwards behind humeral angle, with abbreviated carinae between shoulders. Posterior process of pronotum narrow, long, cone-shaped and reaching apex 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 rounded. Hind wings developed, slightly surpassing apex of posterior process of pronotum. Lower margins of fore femur and midfemur slightly undulated, width of midfemur equal to width of tegmen. Hind femur stubby, antegenicular and genicular denticles acute. Outer side of hind tibia with six to seven spines, inner side with four to five spines. 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 5.0 times its width, upper and lower valvulae with slender saw-like teeth. Subgenital plate longer than wide, posterior margin of subgenital plate triangularly projecting in middle.
Body 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.
Male. Similar to female, but slightly smaller. Width of midfemur distinctly wider than width of tegmina. Subgenital plate short, cone-shaped. Other structures and coloration the same as in female.
Measurements. Length of body: ♂ 7.0– 7.5 mm, ♀ 9.5–10.0 mm; length of pronotum: ♂ 10.0– 10.5 mm, ♀ 11.0– 11.5 mm; length of hind femur: ♂ 4.0– 4.5 mm, ♀ 5.0– 5.5 mm.
Holotype 1♀, 23 July 2012, collected by Wei-An DENG, IZSNU. Paratypes: 1♂ 3♀♀, 23 July 2012 collected by Min-Ping LIN and Li-Liang LIN, IZSNU (2♂ 1♀), SCBHU (2♂ 1♀).
Type locality: China, Guangxi, Shangsi (Shiwanshan Mountain), 21°58’N, 107°50’E, 300m alt.
Diagnosis. New species is similar to Mazarredia convexa Deng, Zheng & Wei, 2007 from which it differs in width of vertex equal to width of one eye in female (width of vertex narrower than width of one eye in M. convexa); longitudinal furrow narrower than width of 1st segment of antennae (width of longitudinal furrow equal to width of 1st segment of antennae in M. convexa); upper margin of pronotum undulated before shoulders and straight behind shoulders in profile (midkeel of pronotum high and lamellar before shoulders, upper margin of pronotum undulated in profile in M. convexa); posterior process of pronotum reaching apex of hind tibia (posterior process of pronotum reaching middle of hind tibia in M. convexa); hind wings developed, surpassing apex of posterior process of pronotum (hind wings reaching the caudal end of pronotum in M. convexa); width of midfemur equal to width of tegmina in female (width of midfemur wider than width of tegmina in M. convexa); hind tibia dark brown (hind tibia black, with light ring in the base in M. convexa).
Etymology. The specific epithet convexaoides is derived from convexa, which means the new species is very similar to Mazarredia convexa.
Distribution. China (Guangxi).
