2. Mazarredia convexa View in CoL sp. nov. ( Fig. 1 View FIGURE 1 )
Diagnosis: Mazarredia convexa sp. nov. can be easily distinguished from other species of the genus by disc of pronotum largely convexed between shoulders.
Description: ♀ Fig. 1 View FIGURE 1 : Size small, stout. Head distinctly exserted above the pronotal surface ( Fig. 1b,1c View FIGURE 1 ), width of an eye 1.25 times the width of vertex, anterior margin of vertex slightly straight, without protruding beyond eyes ( Fig. 1a View FIGURE 1 ), median carina conspicuous. In profile, vertex and frontal ridge forming obtuse round shape ( Fig. 1c View FIGURE 1 ). Frontal costa slightly concave between lateral ocelli, frontal ridge slightly protruding arching between antennae ( Fig. 1b,1c View FIGURE 1 ), width of longitudinal furrow equal to width of first segment of antennae. Antenna filiform, 14-segmented, length of a segment in middle about 6-7 times longer than width, inserted between lower margin of eyes ( Fig. 1c,1d View FIGURE 1 ). Eyes globose, strongly exserted above the pronotal surface ( Fig. 1c View FIGURE 1 ). Lateral ocelli placed on middle of anterior margins of eyes ( Fig. 1b,1c View FIGURE 1 ). Disc of pronotum coarse, with numerous coarse tubercles, anterior margin of pronotum straight and slightly concave in middle ( Fig. 1a View FIGURE 1 ), midkeel of pronotum completed, high and lamellar before shoulders, upper margin of pronotum undulated in profile ( Fig. 1b View FIGURE 1 ). Lateral keels of prozona constricted backward ( Fig. 1a View FIGURE 1 ), disc of pronotum largely convexed between shoulders ( Fig. 1a,1b View FIGURE 1 ), humeral angle rounded, with abbreviated carinae in large convex between shoulders ( Fig. 1a View FIGURE 1 ). Caudal end of pronotum narrow, long cone-shaped, surpassing the top of hind femora, reaching middle of hind tibia ( Fig. 1a,1b View FIGURE 1 ). 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 the caudal end of pronotum ( Fig. 1b View FIGURE 1 ). Upper and lower margins of anterior and middle femora undulated ( Fig. 1b View FIGURE 1 ), width of midfemur slightly wider than the width of tegmina. Hind femur 3.2 times longer than wide, margins of hind femur finely serrulate, antegenicular right angle and genicular denticles acute. Outer side of hind tibia with 5-6 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 first and second sharp, apices of third obtuse ( Fig. 1e View FIGURE 1 ). 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 longer than its width, middle of posterior margin of subgenital plate with a triangular convex ( Fig. 1f View FIGURE 1 ).
Body brown. Fore and middle femora and tibia each with two distinct dark transverse spots. Wings black ( Fig. 1b View FIGURE 1 ). Hind femur brown, lower outer side black ( Fig. 1b View FIGURE 1 ). Hind tibia black, with light ring in the base ( Fig. 1b View FIGURE 1 ).
Male: Body size smaller than female, feature of structure similar to female. Subgenital plate brief coneshaped, apex sharp( Fig. 1g View FIGURE 1 ).
Measurements: Length of body: ♂ 5.5-6.0 mm; ♀ 7.5-8.0 mm, length of pronotum: ♂ 7.5-8.0 mm; ♀ 10.0- 10.5 mm; length of hind femur: ♂ 4.0- 4.2 mm; ♀ 5.0- 5.5 mm.
Holotype: ♀. P. R. CHINA, Guangxi prov., Zhaoping (Xiping), 24.2°N, 110.8°E, 700m alt, 5.v.2006, collected by Wei-An DENG GoogleMaps . Paratypes. Two ♂ s and two ♀ s, Same data as for holotype; one ♂ and four ♀ GoogleMaps s, Guangxi prov., Tengxian (Taiping), 23.4°N, 110.7°E, 400m alt, 8. v. 2006, collected by Shi-Zhen WEI. Material is deposited in the Institute of Zoology, Shaanxi Normal University, Xi’an, China (2 ♂ 4 ♀) and Department of Chemistry and Life Science, Hechi University, China (1 ♂ 3 ♀) GoogleMaps .
Etymology: This new species name is derived from the Latin convexa , meaning disc of pronotum with large convex between shoulders.
Distribution: China (Guangxi).
