3. Mazarredia sfrictivertex View in CoL sp.nov. ( Fig. 2 View FIGURE 2 )

Diagnosis: Mazarredia sfrictivertex sp.nov. is similar to Mazarredia huanjiangensis Zheng et Jiang, 1994 , but differs in: anterior margin of pronotum in contact with hind margins of eyes, upper margin of pronotum undulated in profile, lateral keels of prozona constricted backward, caudal end of pronotum reaching the top of hind tibia, upper and lower margins of middle femora undulated, width of midfemur of female equal to the width of tegmina.

Description: ♀ Fig. 2 View FIGURE 2 : Size small, slender. Head distinctly exserted above the pronotal surface ( Fig. 2b,2c View FIGURE 2 ), vertex very narrow, width of an eye 1.7 times the width of vertex ( Fig. 2a View FIGURE 2 ). Anterior margin of vertex straight, without protruding beyond eyes, median carina conspicuous ( Fig. 2a View FIGURE 2 ). In profile, vertex and frontal ridge forming obtuse round shape ( Fig. 2b,2c View FIGURE 2 ). Frontal ridge slightly protruding arching between antennae ( Fig. 1b,1c View FIGURE 1 ), width of longitudinal furrow narrower than width of first segment of antennae. Antenna filiform, 15-segmented, length of a segment in middle about 7-8 times longer than width, inserted between lower margin of eyes ( Fig. 2c,2d View FIGURE 2 ). Eyes globose, strongly exserted above the pronotal surface ( Fig. 2b,2c View FIGURE 2 ). Lateral ocelli placed on middle of anterior margins of eyes ( Fig. 2d View FIGURE 2 ). Anterior margin of pronotum straight and in contact with hind margins of eyes ( Fig. 2b,2c View FIGURE 2 ), midkeel of pronotum completed, upper margin of pronotum undulated in profile ( Fig. 2b View FIGURE 2 ). Lateral keels of prozona constricted backward ( Fig. 2a View FIGURE 2 ), humeral angle an obtuse shape, with abbreviated carinae between shoulders ( Fig. 2a View FIGURE 2 ). Caudal end of pronotum narrow, long cone-shaped, reaching the top of hind tibia ( Fig. 2a,2b View FIGURE 2 ). Lateral lobes of pronotum little produced outwards, end of posterior angles truncate, posterior margins of lateral lobes of pronotum with two concavities. Tegmina long oval, apex round. Hind wings developed, reaching or slightly surpassing the caudal end of pronotum ( Fig. 2b View FIGURE 2 ). Lower margins of anterior femora undulated, upper and lower margins of middle femora undulated ( Fig. 2b View FIGURE 2 ), width of midfemur equal to the width of tegmina. Hind femur 3 times longer than wide, margins of hind femur finely serrulate, antegenicular right angle and genicular denticles acute. 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, third pulvillus longer than first and second, apices of three pulvilli sharp ( Fig. 2e View FIGURE 2 ). Ovipositor narrow and long, length of upper valvulae 4 times its width, upper and lower valvulae with slender saw-like teeth. Length of subgenital plate slightly longer than its width, middle of posterior margin of subgenital plate with a triangular convex ( Fig. 1f View FIGURE 1 ).

Body brown. Wings black ( Fig. 2b View FIGURE 2 ). Hind femur brown, lower outer side black ( Fig. 2b View FIGURE 2 ). Hind tibia brown.

Male: Body size smaller than female, feature of structure similar to female. Width of midfemur wider than the width of tegmina. Subgenital plate brief cone-shaped, apex sharp ( Fig. 2g View FIGURE 2 ).

Measurements: Length of body: ♂ 6.5–7.0 mm; ♀ 8.5–9.0 mm, length of pronotum: ♂ 9.5–10.0 mm, ♀ 11.5–12.0 mm; length of hind femur: ♂ 4.0– 4.5 mm, ♀ 5.0– 5.5 mm.

Etymology. This new species name is derived from the Latin sfrict and vertex; meaning vertex very narrow, width of an eye 1.7 times the width of vertex.

Distribution: China (Guangxi).
