Material examined. Holotype, male, China: Guizhou, Daozhen, Dashahe Nature Reserve, altitude 1500 m, 29 May 2004, leg. Qiongzhang Song (YZU); paratype, 1 female, Hunan, Zhangjiajie, Tianmen Mountain, altitude 1500 m, 28 July 2009, leg. Jiale Tang (YZU).
Distribution. China (Guizhou, Hunan).
Description. Male. Length 15.0 mm, maximum width of elytra 7.0 mm. Body black, densely clothed with appressed reddish-brown, grayish-yellow and dark grayish-brown silky pubescence, uniformly mixed with sparse grayish-white pubescence. Antenna, scutellum, tibia and tarsus densely clothed with grayish-yellow pubescence; posterior margin of pronotum and sterna densely clothed with dark grayish-brown pubescence, each elytron with a black velvet macula behind the middle, the remainder of the body densely clothed with reddish-brown pubescence.
Head sparsely punctate; frons wider than long, with a central sulcus extending to occiput; eye coarsely faceted, lower lobe slightly narrowed, slightly shorter than gena in front view. Antenna about 1.5 times as long as body; antennal tubercles elevated, widely separated from each other; scape cylindrical, coarsely punctate and rugose, with a developed apical cicatrix; antennomere 3 about as long as scape, slightly longer than antennomere 4, antennomere 4 slightly longer than antennomere 5. Pronotum wider than long, rugose; disc strongly raised centrally, anterior half of the protuberance strongly depressed medianly, forming a broad gap, posterior portion slightly narrowed with a middle longitudinal groove; each side with a blunt spine before the middle. Scutellum small, triangular. Elytra connate, relatively convex, strongly and steeply declivous behind the middle, apex rounded; surface with scattered small tubercles and each elytron with 4 longitudinal rows of tubercles with top glabrous: the first row with tubercles smallest and inconspicuous, along the suture and not reaching the apex; the second row at inner fourth, divided into two parts, each composed of 3 to 4 tubercles, the basal part at basal fourth of elytron, forming a strongly raised blunt ridge, the distal part only reaching to the black macula, the last tubercle of distal part large, strongly elevated and obliquely pointed posteriorly; the third row at the middle of elytron, from basal fourth to lateral side of the black macula, composed of 4 to 5 tubercles; the fourth row behind the humerus, reaching to the center of apical fourth, composed of about 10 tubercles. Metasternum elevated centrally. Legs long, metafemur about as long as abdomen.
Female. Length 17.5 mm, maximum width of elytra 7.0 mm. Similar to male, body larger and broader than male, lateral pronotal spine more swollen basally, tubercles on each elytron arranged in rows mostly larger than male, black macula on each elytron narrower than male, basal 7 antennomeres reaching the apical fourth of elytra (remainder missing).
Female genitalia. Spermatheca approximately S-shaped, tubular, consisting of a basal membranous and apical strongly sclerotized part, basal membranous tube nearly C-shaped, basal section of sclerotized tube narrowed and gradually curved, apical section of sclerotized tube gradually expanded and slightly curved, blunt distally ( Fig. 73 View FIGURES 63 – 74 ). Spermathecal duct is borne at the middle of bursa copulatrix; spermathecal gland is borne at the joint of membranous and sclerotized part of spermatheca.
Comments. The new species is similar to M. tuberculatum Breuning and M. granulutum Chiang , but it differs from the two in having the body mostly clothed with reddish-brown pubescence on dorsum, the pronotum distinctly clothed with bicolored pubescence except the sparse grayish-white pubescence (the posterior margin clothed with dark grayish-brown pubescence, but in M. tuberculatum Breuning and M. granulutum Chiang , the pronotum is clothed with brown to dark-brown pubescence throughout) (Figs 43, 52, 55), the tubercles of outside 3 rows on each elytron more elevated and the apical declivity steeper. Further, it is distinguished from M. tuberculatum Breuning by its central protuberance of pronotum with broader anterior-medial gap, elytral tubercles arranged in rows more prominent, elytral black maculae larger; it is distinguished from M. granulutum Chiang by basal 7 antennomeres of female reaching to basal fourth of elytron (in M. granulutum Chiang , whole female antenna approximately reaching to the basal fourth of elytron), female elytral maculae elongate, not semi-rounded ( Figs 9, 11 View FIGURES 1 – 14 , 23 View FIGURES 15 – 26 , 56).
Wang (2005) misidentified the male specimen as M. granulutum Chiang according to the semi-rounded black macula on each elytron which well matches the original description of M. granulutum Chiang. Since the female specimen has been found in Hunan, the status of the species is clear.
Etymology. The new species is named after Prof. Shunan Jiang (= Shunan Chiang) in memory of the famous Chinese taxonomist of longicorn beetles who died in June 2013. Chinese name spells as Jiǎngshì Jùliútiānniú in Chinese phonetic alphabet.
