Type material.

Holotype: • male, “ CHINA. Hubei, Shennongjia / Jinhouling / 2,520 m, 2021. V. 25 / leg. Wen-Xuan Bi ” ( SNUC) .

Description.

Male (Fig. 14 View Figures 13–24 ). BL = 3.44, BW = 1.06 mm. Body and appendages mostly reddish brown with dull appearance; head, scape and antennomeres XI darker; elytra mostly brown with narrowly reddish brown apical margins; femora and ventral surface dark brown. Head moderately covered with yellowish to tawny pubescence; antennae covered with fine brownish pubescence intermixed with very sparse yellowish hairs, lacking light-colored rings; pronotum clothed with similar pubescence to head, except for the tawny hairs tending to form a narrow strip across the midline; scutellum densely covered with whitish hairs; elytra predominantly covered with light gray pubescence which intermixed with sparse tawny hairs mainly scattered near base or along suture, the pubescence partially interrupted by a few very small glabrous spots; disk provided with a vague patch of dark brown pubescence behind the scutellum, not exceeding basal 1 / 5, and with a same-colored narrow band slightly behind the midlength, distinctly broadened along the suture and directed posteriorly; legs and ventral surface moderately covered with fine yellowish pubescence throughout.

Head slightly wider than pronotal anterior margin, shallowly concave between antennal tubercles; frons densely and finely punctate and sculptured. Eyes deeply emarginated, upper and lower eye lobes connected by 1 row of ommatidia; lower eye lobe ~ 2 × as long as wide, 1.8 × as long as gena. Antennae short and slender, <0.9 × body length; scape weakly clavate, finely punctate and sculptured; antennomere III subequal to IV, 1.1 × as long as scape, 1.6 × as long as antennomere V.

Pronotum ~ 0.9 × as long as width across lateral tubercles, 1.2 × as long as basal width; weakly constricted at base, without distinct transverse grooves; lateral tubercles small with acute apices, situated near basal 2 / 5; disk weakly convex, densely finely punctate and sculptured with a few interspersed large setigerous punctures.

Elytra elongate, EL / EW = 2.2, EL / PL = 3.2, gently constricted behind broadly rounded humeri, weakly dilated near apical 2 / 5, then convergent toward separately rounded apices; lacking subbasal tubercles but with pair of indistinct swellings in basal quarter, feebly elevated in lateral view (Fig. 34 View Figures 25–43 ); disk sparsely and finely punctate, punctures becoming shallower toward apical 1 / 3, hardly forming rows. Ventral surface finely punctate. Legs moderately long and thick, metatibiae not exceeding elytral apices; femora not distinctly thickened; tarsal claws appendiculate.

Male terminalia. Tergite VIII (Fig. 57 a View Figures 52–60 ) transverse, slightly emarginated apically with broadly rounded sides; apical margin bearing few moderately long setae mainly at sides. Tegmen (Fig. 57 b View Figures 52–60 ) with lateral lobe distinctly broadened subapically with rounded apex; bearing a few very long setae at apices and some short fine setae mainly on apical half ventrally. Median lobe (Fig. 57 c View Figures 52–60 ) moderately curved in lateral view; apex subacute.

Female. Unknown.

Remarks.

This new species resembles M. coenosa and occurs sympatrically at its type locality (Map 1 View Map 1 ). But it can be readily distinguished from the latter by the antennae being comparatively shorter, distinctly shorter than 0.9 × of body length; scape less thickened; flagellomeres without basal rings of light-colored pubescence; elytra remarkably longer in relation to the pronotal length; integument of elytra almost uniformly brown, without a light-colored portion in basal half; and elytral dark-colored maculae highly reduced, occupying less than quarter of the total discal surface.

Etymology.

The specific epithet, Shennong, refers to one of the legendary three emperors in Chinese mythology and culture, which is also the origin of the type locality “ Shennongjia ” (literally means Shennong’s ladder). It is a noun in apposition.
