Diagnosis.

This species is similar to M. flexa Wang et al., 2014 in male genitalia, but it can be differentiated from the latter by the following characters: 1) interstylar region obviously irregularly convex, the left part obviously larger than the right, while in the latter, interstylar region obviously regularly convex; 2) the left part of the accessory structure of median phallomere with a brush, absent in the latter.

Measurements

(mm). Male (n = 3), pronotum: length × width 2.4-2.6 × 3.2-3.5, tegmina length: 9.3-9.9, overall length: 11.2-11.9.

Description.

Male. Coloration: body yellowish-brown with pale brown (Fig. 7A, B ). Face yellowish-brown. Interocular space with a dark brown band. Ocellar spots white and small, interocellar space with a brown band. Antennae light linen- colored. Clypeus medium yellowish-brown (Fig. 7C ). Maxillary palps light yellowish-brown to yellowish-brown (Fig. 7E ). Pronotal disc yellowish-brown with brown stripes and two lateral borders light yellow (Fig. 7D ). Tegmina light fawn, wings and legs pale brown (Fig. 7F, G ). Abdomen light linen with pale yellowish-brown. Cerci pale brown (Fig. 7K ). Styli light yellowish-brown (Fig. 7M ). Head: vertex slightly exposed, distance between interocular same length antennal sockets space (Fig. 7C ). Pronotum nearly trapezoidal, broader than long, the widest part after the midpoint, the front and posterior margins nearly straight, and postero-lateral angle blunt and round; disc with symmetrical irregular macules (Fig. 7D ). Third and fourth palpi of approximately the same length, both obviously longer than fifth, fifth palp obviously expanded (Fig. 7E ). Tegmina and wings: tegmina and wings developed, both extending the end of abdomen (Fig. 7A-B ). Tegmina with ScP simple, R multi-branched, M straight with seven complete branches. Hind wings with ScP and RA expanded at apex; M straight and simple, without branches; CuA with five complete branches (Fig. 7F, G ). Legs: anteroventral margin of front femur type B3 (Fig. 7H ). Pulvilli present on four proximal tarsomeres. Tarsal claws symmetrical and specialized, inner margin serrated, arolia present (Fig. 7I ). Abdomen and genitalia: eighth abdominal tergum specialized with a tuft (Fig. 7J ). Supra-anal plate transverse, posterior margin convex. Paraprocts simple, similar, splitting into two pieces, base with tufts (Fig. 7K ). Subgenital plate asymmetrical. Styli similar, slender, distinctly separated; interstylar region obviously irregularly convex, middle part concave, two lateral angles spherical with some short thorns, left angle obviously larger than right (Fig. 7M ). Left phallomere complex, irregular bone-shaped, with a long spine (Fig. 7L ). Median phallomere slender rod-shaped, base splitting into some long spines; the accessory structure arched, at leftmost end with a brush (Fig. 7M ). Hook phallomere on right side, base curved inwards with a short spine (Fig. 7N ).
