Type material.

Holotype: China • ♂; Mt Daming, Guangxi Province; 2-VII-2015; Lu Qiu, Qi-Kun Bai leg; SWU-B-EC141201. Paratype: China • 1♂; same data as for holotype; SWU-B-EC141202.

Diagnosis.

This species is similar to M. flexa Wang et al., 2014 in general appearance and male genitalia, but it can be differentiated from the latter by the following characters: 1) interstylar region obviously convex with both sides curved inwards, three spines on each side, while in the latter, two sides curled up with 5-6 small thorns; 2) the left end of the accessory structure with a slender bone; the latter absent.

Measurements

(mm). Male (n = 2), pronotum: length × width 1.6-2.1 × 2.6-2.9, tegmina length: 10.3-11.2, overall length: 12.5-13.1.

Description.

Male. Coloration: body yellowish-brown (Fig. 5A, B ). Face yellowish-brown. Interocular space with a dark brown band. Ocelli spots white, interocelli space with a brown band. Antennae dark linen-colored. Clypeus dark yellowish-brown (Fig. 5C ). Maxillary palps yellowish-brown (Fig. 5E ). Pronotal disc yellowish-brown with dark brown stripes, and lateral borders light linen-colored (Fig. 5D ). Tegmina pale yellow, wings medium brown (Fig. 5F, G ). Abdomen pale yellowish-brown. Cerci pale yellowish-brown (Fig. 5K ). Styli faint yellow (Fig. 5M ). Head: vertex slightly exposed, distance between interocular same length as antennal sockets space (Fig. 5C ). Pronotum nearly trapezoidal, broader than long, the widest part after the midpoint, the front and posterior margins nearly straight, and the postero-lateral angle blunt and round; the disc with symmetrical irregular macules (Fig. 5D ). The third, fourth palpi of approximately same length, both obviously longer than the fifth, the fifth obviously expanded (Fig. 5E ). Tegmina and wings: tegmina and wings fully developed, both extending beyond the end of abdomen (Fig. 5A, B ). Tegmina with ScP simple, R multi-branched, M straight with six complete branches. Hind wings with ScP and RA expanded at apex; M straight and simple, without branches; CuA with five complete branches (Fig. 5F, G ). Legs: anteroventral margin of front femur type B3 (Fig. 5H ). Pulvilli present on four proximal tarsomeres. Tarsal claws symmetrical and specialized, inner margin serrated, arolia present (Fig. 5I ). Abdomen and genitalia: eighth abdominal tergum specialized with a tuft (Fig. 5J ). Supra-anal plate transverse, posterior margin protruded. Paraprocts similar, splitting into two pieces, apex with tufts (Fig. 5K ). Subgenital plate symmetrical, lateral borders flip inwards with spines and hairs. Styli similar, slender; interstylar region obviously convex, two sides convex and curved inwards, each side with three spines (Fig. 5M ). Left phallomere complex, irregular bone-shaped, with a short spine (Fig. 5L ). Median phallomere slender rod-shaped, obviously curved, apex with ordered long spines; the accessory structure arched, on at rightmost end with spines, left apex with a slender bone with apex sharp (Fig. 5M ). Hook phallomere on the right side, apex curved inwards with a short spine (Fig. 5N ).

Female unknown.

Etymology.
