Material examined. Holotype, female, China: Hubei, Yichang, Dalaoling Nature Reserve, N 31° 02′ 38.00″, E 110° 57′ 16.69″, altitude 1280 m, 1 May 2010, leg. Guanglin Xie (YZU). Paratype, 1 male, the same locality, 23 July 2010, leg. Guanglin Xie (YZU); 1 female, the same locality, 23 July 2010, leg. Wei Li; 1 female, the same locality, 30 April 2014, Xia Zou(YZU).

Distribution. China (Hubei).

Description. Female. Length 15–16 mm, maximum width of elytra 7.0 mm. Body black, densely clothed with appressed yellowish-brown pubescence and uniformly mixed with sparse grayish-white pubescence on ventral surface and femora (except for the antenna, scutellum, most of tibia and whole tarsus clothed with grayish-yellow pubescence).

Head sparsely punctate; frons wider than long, with a central sulcus extending to occiput; eye coarsely faceted, lower lobe narrow, clearly shorter than gena in front view. Antenna about 1.4 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 with a large central protuberance, center of the protuberance strongly depressed towards front and forming a broad gap, posterior portion of the protuberance slightly narrowed with a middle longitudinal groove; each side with a blunt spine before the middle. Scutellum small, triangular. Elytra connate, nearly oval, convex, steeply declivous behind the middle, apices separately rounded; each elytron with tubercles with top glabrous and slightly pointed backward arranged in 4 longitudinal rows: the first row with tubercles smallest and inconspicuous, along the suture and not reaching the apex; the second row at inner fourth of elytron, from basal fourth to the top of declivity, with a large and blunt basal ridge composed of 5 to 7 tubercles; the third row at the middle of elytron, from basal fourth to apical fourth, composed of 4 to 5 strongly raised tubercles; the fourth row behind the humerus, reaching to the center of apical fourth, composed of about 10 dentate tubercles, the remaining surface scattered with small tubercles. Procoxal cavity closed posteriorly, mesocoxal cavity open at side. Legs long, femora sparsely punctate on apical half, metafemur about as long as abdomen.

Female genitalia. Spermatheca approximately U-shaped, tubular, consisting of a basal membranous and apical sclerotized part, basal membranous tube crescent-shaped, sclerotized tube acutely curved near the joint between the membranous and sclerotized tube, the apical section of sclerotized tube slightly curved in the same direction as the membranous tube, acute distally ( Fig. 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.

Male. Length 16.0 mm, maximum width of elytra 7.0 mm. Similar to female, antenna about 2.2 times as long as body, antennomere 3 slightly longer than scape; the tubercles of outside 3 rows on each elytron more elevated, partly coalesced and distinctly pointed backward apically, metafemur longer than abdomen.

Comments. The new species is similar to M. tuberculatum Breuning and M. jiangi sp. nov. in appearance, but the elytra are without black maculae (Figs 59, 62).

Etymology. The species is named after the type locality Dalaoling. Chinese name spells as Dàlǎolǐng Jùliútiānniú in Chinese phonetic alphabet.
