Type material.

Holotype: China • ♂ (IZAS); Anhui, Jinzhai, Tiantangzhai, Tiantangzhai Scenic Spot; 952.56 m; 8.V.2021, K. D. Zhao & X. C. Zhu. leg.

Description.

Male (Fig. 6A View Figure 6 ). Length 11.2 mm, width at humeri 2.3 mm. - Body black. Pronotum dark red with black median patch, elytra dark red. Surface covered with decumbent red pubescence. - Head relatively small. Eyes small, interocular distance approximately twice as large as eye diameter. Antennae (Fig. 5G View Figure 5 ) flabellate, overlapping two-thirds the length of the elytra when inclined. Antennomere II transverse; III-XI lamellate, pointed at apices, antennomere III with lamella nearly as long as joint itself; lamella of IX longest, 3.3 times longer than joint itself. - Pronotum trapezoidal, 1.25 times wider than long, disc present with a median longitudinal keel extending from anterior margin to middle part. Anterior margin weakly convex, lateral margins sinuate and posterior margin bisinuate; anterior angles rounded, posterior angles posterior angles sharp and prominently projected. Scutellum trapezoidal, feebly emarginate at apex. - Elytra slender and subparallel, 3.9 times longer than humeral width. Each elytron with four costae, costa I weak but visible in whole length; costae II and IV stronger than costa III; costa III visible only at basal part. - Aedeagus: median lobe slender, strongly curved near middle in lateral view, at an angle of ca. 120° between basal and apical parts of dorsal side, moderately arcuate at base part, subapical part moderately inflated dorsally (Figs 4L View Figure 4 , 8A View Figure 8 ); parallel-sided at basal part in ventral view, subapical part strongly inflated laterally and almost symmetrical (Figs 4J, K View Figure 4 , 8B View Figure 8 ), with a fusiform ventral cavity (Fig. 4J View Figure 4 ); apical part feebly swollen (Fig. 4J, K View Figure 4 ), with a deep U-shaped notch at apex (Fig. 4K View Figure 4 ).

Female.

Unknown.

Diagnosis.

This species resembles M. atronotatus in the shapes of pronotum and elytra but can be distinguished by the dark red pronotum and elytra (Fig. 6A View Figure 6 ), with orange pronotum and elytra in the latter. It also looks like M. huoditangensis sp. nov. but differs from the latter in the bicolored pronotum and slender median lobe, which is parallel-sided at the basal part in ventral view (Figs 4K View Figure 4 , 8B View Figure 8 ). In comparison, the pronotum of M. huoditangensis sp. nov. is unicolored, and the median lobe is stout and swollen at the basal part in ventral view (Figs 7J View Figure 7 , 8B View Figure 8 ).

Etymology.

The specific name is derived from the Latin " mimus " (imitator), referring to its similarity to M. atronotatus .
