Description.

Male (Fig. 1 View Figures 1–12 ). BL = 3.07–4.50, BW = 0.95–1.41 mm. Body shiny, body and appendages usually mostly reddish brown (or testaceous), head, middle portion of pronotum, scape, apical one or two antennomeres, femora and tibiae occasionally brownish; elytra typically uniformly reddish brown in basal 2 / 5 (rarely darkening posteriorly), remaining portion blackish; ventral surface with metaventrite brownish, abdominal ventrites dark brown to blackish. Head and appendages provided with very sparse whitish to yellowish hairs, relatively denser on frons, scape and legs, finer on apical seven antennomeres; antennomeres III-XI additionally bearing short dark brown setae throughout; pronotum with dense whitish hairs on extreme base, forming narrow transverse stripe, of which the median hairs are directed toward scutellum; scutellum covered with whitish hairs, becoming denser posteriorly; each elytron with whitish hairs forming dense transverse band occupying posterior quarter of the light-colored integument but not reaching the suture, supplemented by similar sparse hairs along basal 1 / 3 of suture and shorter ones near apex; ventral surface clothed with sparse yellowish hairs, denser on lateral mesoventrite, posterolateral metaventrite and posterior metanepisternum.

Head slightly wider than pronotal anterior margin, shallowly concave between antennal tubercles; frons sparsely and finely punctate. Eyes moderately emarginated, upper and lower eye lobes connected by two rows of ommatidia; lower eye lobe 1.6 × as long as wide, 1.4 × as long as gena. Antennae moderately stout, AL / BL = 1.0–1.1; scape moderately clavate, finely punctate and sculptured; antennomere III 1.1 × as long as IV, 1.4 × as long as scape, 1.6 × as long as antennomere V.

Pronotum subequal in length and width across lateral tubercles, ~ 1.4 × as long as basal width, constricted at basal 1 / 5 by a deep groove; lateral tubercles situated slightly behind midlength, moderately developed, with acute apices; disk smooth, strongly convex in lateral view (Fig. 27 View Figures 25–43 ), very sparsely and shallowly punctate.

Elytra elongate, EL / EW = 2.0–2.1, EL / PL = 2.4–2.7, gently constricted behind obtusely angulate humeri, slightly dilated at apical 2 / 3, then convergent toward conjointly rounded apices; moderately convex at apical 2 / 3 in lateral view (Fig. 27 View Figures 25–43 ). Each elytron provided with one large subbasal tubercle tufted with intermixed dense short and sparse long setae at tip; disk sparsely and deeply punctate; punctures gradually becoming shallower posteriorly, not forming rows (at least on basal 2 / 3). Ventral surface sparsely and finely punctate; abdominal ventrites finely sculptured. Legs moderately long and thick; metatibiae slightly exceeding elytral apices; tarsal claws appendiculate (Fig. 41 View Figures 25–43 ).

Male terminalia. Tergite VIII (Fig. 52 a View Figures 52–60 ) slightly wider than long, broadly rounded apically with short fine marginal setae. Tegmen (Fig. 52 b View Figures 52–60 ) with lateral lobe subparallel-sided, apices subacute bearing three or four long setae and few short fine setae. Median lobe (Fig. 52 c View Figures 52–60 ) moderately curved in lateral view; apex subacute. Endophallus in everted condition (Fig. 59 View Figures 52–60 ) S-shaped, with BPH, MPH and APH well defined; cs present; BPH moderately swollen dorsally at midlength and ventrally at apical 1 / 3; MPH 3 × longer than APH, constricted at extreme base, then moderately swollen forming a ventral projection pointing backwards, provided with a small sclerotized tubercle at anterior edge of the basal constriction, strongly curved dorsally near apical 1 / 3, with spacing a pair of small dorsal tubercles before the incurvation; APH short (possibly incompletely inflated); ejaculatory duct single; gonopore situated at apex of APH.

Female (Fig. 2 View Figures 1–12 ). BL = 2.93–4.83 mm, BW = 0.99–1.52 mm. Almost identical to male in general appearance. Appendages relatively shorter. AL / BL = 1.0, EL / EW = 1.9–2.1.

Remarks.

This species was described by Gressitt (1940) based on a single female from Shanghai, representing the first record of the genus from China. Pesarini and Sabbadini (1997) subsequently described M. bicristata based on two female specimens collected at Huashan, Shaanxi, and distinguished it from M. savioi by its “ highly raised ” (vs “ much smaller, rounded at the tip and moderately raised ”) elytral subbasal tubercles. However, they did not examine the type material or any voucher specimens of M. savioi . Comprehensive comparison of both original descriptions, examination of the M. savioi holotype, and analysis of extensive topotypic material from both species reveal no diagnostically significant morphological differences. Consequently, M. bicristata Pesarini & Sabbadini, 1997 is proposed as a junior synonym of M. savioi Gressitt, 1940 .

This species typically exhibits reddish-brown integument on the head, pronotum, and appendages, although specimens from Hubei and Zhejiang occasionally show darker brown coloration of these structures. These differences are minor and can be attributed to intraspecific variation.
