Description.

Male (Fig. 7 View Figures 1–12 ). BL = 4.39–5.25, BW = 1.23–1.49 mm. Head and pronotum mostly dark brown, pronotal basal quarter and lateral tubercles, scutellum, elytral basal half and a narrow apical band reddish brown, remaining portion of elytra blackish; antennae mostly dark brown, becoming slightly lighter toward apical segments; legs mostly dark brown, except coxae, trochanters, basal 1 / 3 of femora and tarsi, which are reddish brown; ventral surface mostly reddish brown, anterior margin of prosternum and abdominal ventrites dark brown, lighter on ventrite V. Head and pronotum provided with very sparse yellowish hairs, almost imperceptible; scutellum covered with dense yellowish hairs on posterior edge; each elytron with very sparse yellowish hairs scattered mainly on basal half (including suture) and near apical 1 / 5, slightly denser shortly behind the subbasal tubercle, and with dense suberect silvery-white hairs forming narrow, sharply arched band near the midlength, just along the anterior edge of dark but shiny portion, not reaching suture; elytral long setae mostly dark-brown to blackish except for those on basal half intermixed with yellowish; appendages clothed with fine moderately dense yellowish hairs; ventral surface covered with whitish to yellowish hairs, denser on lateral sides.

Head slightly wider than pronotal anterior margin, moderately concave between antennal tubercles; frons and vertex densely and coarsely punctate. Eyes deeply emarginated, upper and lower eye lobes connected by 1 row of ommatidia; lower eye lobe ~ 1.8 × as long as wide, 1.5 × as long as gena. Antennae slender, AL / BL = 1.1; scape moderately clavate, densely and finely punctate and sculptured especially on frontal surface; antennomere III slightly longer than IV, 1.2 × as long as scape, 1.5 × as long as antennomere V.

Pronotum elongate, 1.1 × as long as width across lateral tubercles, 1.6 × as long as basal width, with a transverse constriction and deep groove at base; lateral tubercles situated near basal 2 / 5, moderately developed with acute apices; disk strongly convex, very coarsely rugose-punctate.

Elytra elongate, EL / EW = 2.3, EL / PL = 2.4, subparallel-sided on basal 2 / 5, gently dilated near apical 2 / 5, then convergent toward conjointly rounded apices; weakly convex near apical 2 / 5 in lateral view (Fig. 30 View Figures 25–43 ); humeri obtusely angulate. Each elytron provided with one large subbasal tubercle tufted with dense short setae at tip; disk with coarse sparse punctures forming irregular rows on basal half, abruptly becoming finer and sparser on dark portion, and displays dense microsculpture predominantly behind subbasal tubercle on basal half. Ventral surface sparsely and finely punctate. Legs moderately long and thick; meso- and metatibiae almost straight; metatibiae slightly exceeding elytral apices; tarsal claws appendiculate.

Male terminalia. Tergite VIII (Fig. 55 a View Figures 52–60 ) transverse, broadly rounded apically with short fine setae along apical margin. Tegmen (Fig. 55 b View Figures 52–60 ) with lateral lobe constricted near midlength and subacute apically; apices bearing dense fine setae of moderate length. Median lobe (Fig. 55 c View Figures 52–60 ) moderately curved in lateral view; apex subacute.

Female. BL = 4.63 mm, BW = 1.39 mm. Almost identical to male in general appearance. Body slightly stouter and appendages relatively shorter. AL / BL = 1.0. EL / EW = 2.1.

Remarks.

This new species is most similar to M. rugosula Holzschuh, 2003 from northern India in general habitus. However, it can be distinguished from the latter by the comparatively longer elytra, EL / EW = 2.2 versus 2.1; disk provided with dense microsculpture on basal half; dark portion of elytra shiny, lacking dense dark brown pubescence; absence of apical transverse band of white pubescence; and appendages, particularly the scape and tibiae, much darker.

Etymology.

The new species is dedicated to our friend Ms. Gan-Yan Yang (nicknamed Yanzi), who collected a portion of the type series.
