Type material.

Holotype: • male, “ CHINA. Yunnan, Longchuan / Banggunjianshan / 1,700 m, 2018. VI. 7 / leg. Wen-Xuan Bi ” ( SNUC) .

Description.

Male (Fig. 8 View Figures 1–12 ). BL = 5.17, BW = 1.46 mm. Coloration nearly identical to M. yanziae , except for the following distinguishing features: the elytral arch-shaped band of silvery-white hairs obliquely divided the anterior part of the dark portion, the dark portion appears non-shiny due to coverage of very fine dark brown hairs throughout, becoming white near its posterior edge where it vaguely forms a transverse band, and the appendages apparently lighter, with antennae almost entirely light orangish and abdominal ventrite V light reddish brown.

Structures also similar to M. yanziae , with the following exceptions: the head with frons moderately punctate, punctures becoming shallower and finer on the vertex. Eyes weakly emarginated, with upper and lower eye lobes connected by 2–3 rows of ommatidia; lower eye lobe ~ 1.6 × as long as wide, 1.8 × as long as gena. Antennae comparative stouter, antennomere III subequal to IV, 1.4 × as long as the scape, and 1.5 × as long as antennomere V.

The pronotum 1.1 × as long as width across lateral tubercles, 1.5 × as long as basal width, featuring both a shallow groove near the apical 1 / 5 and a deep groove near the basal 1 / 5; lateral tubercles situated near basal 2 / 5, moderately developed with acute apices; the disk strongly convex, finely rugose-punctate.

The elytra are elongate, EL / EW = 2.3, EL / PL = 2.5, subparallel-sided on basal 3 / 5 before converging toward conjointly rounded apices. Each elytron provided with one large subbasal tubercle, carinate on anterior half and tufted with dense short setae and a few long setae at tip; the disk shows sparse, coarse punctures at basal half that become shallower posteriorly, completely lacking microsculpture. Legs are moderately long and thick; with metatibiae slightly curved inward and extending beyond the elytral apices.

Male terminalia. Tergite VIII (Fig. 56 a View Figures 52–60 ) slightly wider than long with a subacute apex; apical margin bearing short fine setae. Tegmen (Fig. 56 b View Figures 52–60 ) with lateral lobe gradually narrowed towards subacute apex; apices bearing a few very short setae. Median lobe (Fig. 56 c View Figures 52–60 ) moderately curved in lateral view; apex obtuse.

Female. Unknown.

Remarks.

This new species resembles both M. rugosula Holzschuh, 2003 and M. yanziae sp. nov. by the general habitus, but can be distinguished from them by the eyes weakly emarginated, upper and lower eye lobes connected by 2–3 rows of ommatidia instead of 1 row; pronotal disk comparatively smooth, not coarsely rugose-punctate; elytra indistinctly dilated at apical 2 / 5; elytral arch-shaped band of silvery-white hairs dividing the anterior part of the dark portion instead of restricted to its anterior edge; the dark elytral surface covered with very fine dark brown hairs (neither thickly haired nor glabrous and shiny); appendages stouter; and metatibiae curved inward.

Etymology.

The new species is dedicated to Mr. Carolus Holzschuh, who kindly provided material from his collection for this study.
