Diagnosis.
The species resembles M. yunnanus Kazantsev, 2001 in appearance, but can be distinguished from the latter by the lamella of antennomere III 1.1 times as long as the antennomere itself ( Fig. 2D View FIGURE 2 ); subapical part of phallus strongly inflated laterally in ventral view, 3.5 times as wide as basal part ( Fig. 3K View FIGURE 3 ) and strongly inflated ventrally in lateral view ( Fig. 3L View FIGURE 3 ). In comparison, the lamella of antennomere III of M. yunnanus 0.8 times as long as the antennomere itself ( Kazantsev 2001: fig. 1); subapical part of phallus feebly inflated laterally in ventral view, 2.5 times as wide as basal part ( Kazantsev 2001: fig. 2) and flat ventrally in lateral view ( Kazantsev 2001: fig. 3).
Etymology. The specific name is derived from the Latin sub- (under, below, beneath) and apex (summit, peak, tip), referring to its characteristic subapical part of phallus.
Type material. Holotype. CHINA • ♂ (MHBU), Yunnan, Nujiang, Biyuhe, 2600‒2900m, VII.2023, Z. Pan leg.
Description. Male ( Fig. 2D View FIGURE 2 ). Length 12.0 mm, width at humeri 3.1 mm.
Body black. Pronotum and elytra orange red. Surface covered with decumbent orange red pubescence.
Eyes small, interocular distance about twice greater than the diameter of an eye.Antennae flabellate, overlapping basal 2/3 length of elytra when inclined, antennomeres III‒XI lamellate and slender, lamellae pointed at apices, lamella of III 1.1 times as long as the antennomere itself, lamella of VIII longest, 2.6 times longer than joint itself ( Fig. 2D View FIGURE 2 ).
Pronotum trapezoidal, 1.1 times wider than long. Anterior margin widely rounded and projecting anteriad, lateral margins sinuate and posterior margin bisinuate; anterior angles rounded, posterior angles sharp and projecting laterally. Scutellum trapezoidal, straight at apex ( Fig. 2D View FIGURE 2 ).
Elytra leaf-like, 3.1 times longer than humeral width. Costa I as strong as II and IV, costa III weak but visible in whole length ( Fig. 2D View FIGURE 2 ).
Aedeagus ( Figs 3J–L View FIGURE 3 ) moderately sclerotized. Parameres moderately developed and spoon-shaped, about 2/7 length of phallus, with lateral margins converging apically in ventral view ( Fig. 3K View FIGURE 3 ) and widely emarginate in lateral view ( Fig. 3L View FIGURE 3 ). Phallus abruptly expanded at basal 1/4 portion, then parallel-sided in dorsal and ventral views ( Figs 3J, K View FIGURE 3 ), subapical part strongly and asymmetrically inflated laterally, about 3.5 times as wide as basal part, with a fusiform ventral-cavity, apical part parallel-sided, apex about 0.32 times as wide as subapical part; basal part bisinuate at basal part and bent dorsally near middle in lateral view ( Fig. 3L View FIGURE 3 ), subapical part strongly inflated ventrally, apical part progressively constricted distad.
Female. Unknown.
Distribution. China (Yunnan).
