Type material.
Holotype: China • ♂ (IZAS); Shaanxi, Ningshan, Huoditang Forestry; 2.VI.2007; M. Y. Lin. leg.
Description.
Male (Fig. 6C View Figure 6 ). Length 8.0 mm, width at humeri 1.8 mm. - Body brown to black. Pronotum, elytra and scutellum dark red. Surface covered with decumbent red pubescence. - Head relatively small. Eyes small, interocular distance approximately twice as large as eye diameter. Antennae (Fig. 5F View Figure 5 ) flabellate, overlapping half-length of elytra when inclined. Antennomere II transverse; III-XI lamellate, lamella of III 1.1 times longer than joint itself; lamella of VII longest, 4.5 times longer than joint itself.
Pronotum trapezoidal, 1.3 times wider than long, disc present with a median longitudinal keel extending from anterior margin to middle part. Anterior margin weakly convex and forms a small pointed process, lateral margins sinuate and posterior margin straight; anterior angles confluent with anterior margin, posterior angles posterior angles sharp and prominently projected. Scutellum trapezoidal, straight at apex. - Elytra slender and subparallel, 4.0 times longer than humeral width. Each elytron had four costae, costae I, II and IV, which were stronger than costa III. - Aedeagus: median lobe stout, strongly curved near middle in lateral view, at an angle of ca. 130° between basal and apical parts of dorsal side, moderately arcuate at base part, subapical part strongly inflated dorsally (Figs 7K View Figure 7 , 8A View Figure 8 ); moderately swollen at basal part in ventral view, subapical part strongly inflated laterally and almost symmetrical (Figs 7I, J View Figure 7 , 8B View Figure 8 ), with a fusiform ventral cavity (Fig. 7J View Figure 7 ); apical part gradually narrowed distad (Fig. 7I, J View Figure 7 ), with a deep V-shaped notch at apex (Fig. 7J View Figure 7 ).
Female.
Unknown.
Diagnosis.
This species is more similar to M. atronotatimimus sp. nov. (described below) in the general shape of the median lobe but differs from the latter in the unicolored pronotum and in the stout median lobe, which is swollen at the basal part in ventral view (Figs 7J View Figure 7 , 8B View Figure 8 ). In contrast, in M. atronotatimimus sp. nov., the pronotum has a black patch in center of disc and median lobe are slender and parallel-sided at the basal part in ventral view (Figs 4J, K View Figure 4 , 8B View Figure 8 ).
Etymology.
The specific name is derived from its type locality, Huoditang, Shaanxi Province, China.
Distribution.
China (Shaanxi).
