Figs 13–23, 24–28
Body length: male: 4.97–5.05 mm (n=6), female: 5.55–5.59 mm (n=5).
Coloration. Body yellowish white to orange, females are lighter in color than males. Crown yellowish-white, with two longitudinal bright red stripes starting from the top of the head back to the end of the clavus, gradually darkening from the clavus (Fig. 13). Face yellowish white, eyes yellowish-brown (Fig. 17). Pronotum with two additional bright red stripes on each side near the lateral margin (Fig. 15). Forewings dark grey longitudinal stripe on commissural margin, extended along entire length. Outer cells dark grey and medial area of third cells with a black spot (Fig. 17). Legs yellowish white.
Head and thorax. Anterior margin of crown slightly inclinate and elevated, median length is close to width between the eyes (1: 1.18) (Figs 13, 15), apex of head truncate in lateral view, with face flat (Fig. 16). Width of face including eyes approximately 0.8 times length (1: 1.2) (Fig. 17). Pronotum transversely wide, width slightly wider than head including eyes (1.18: 1), length evidently longer than medium length of crown (1.78: 1) (Fig. 15). Forewing length is about 4.5 times as long as the widest part (4.49: 1) (Fig. 13).
Male genitalia. Pygofer transversely broad in lateral view, with many long setae in distal half, tubercular process at apical 2/3 of ventral margin (Fig. 19). Valve triangular, subgenital plate elongated (Fig. 23).Style twisty, apical nipple-like process pointing outwards (Fig. 22). Connective V-shaped, outer margin of base concave inward, apex arc-shaped (Fig. 21). Aedeagus tubularly curved, stout at base, tapering towards tip, gonopore at the apex (Fig. 20).
Female genitalia. Sternite VII with anterior margin nearly straight, lateral margin posteriorly convergent, posterior margin concave, slightly bulging in the middle (Fig. 28). First valvula weakly curved with strigate sculpture extended to dorsal margin, slightly wider at the apex 1/3, apically tapering (Figs 24, 25). Second valvula dorsal margin with numerous arched and distinct regular teeth, each tooth with secondary dentition, distal 1/3 with very closely packed much smaller teeth (Figs 26, 27).
Material examined. HOLOTYPE: ♁, China: Guangxi, Guilin City, Xing’an County, Maoer Mountain (25°86’N, 110°49’E), 15 July 2015, Qiang Luo and Meng-Shu Dong; paratypes: 6♁♁ 5♀♀, China: Guangxi, Guilin City, Xing’an County, Maoer Mountain (25°86’N, 110°49’E), 15 July 2015, Qiang Luo and Meng-Shu Dong.
Distribution. China (Guangxi).
Host Plant. Bamboo.
Etymology. This species is named in honor of Mr. Meng-Shu Dong, collector of the new species.
Remarks. The new species is most similar to M. (B.) ventrospina (Chen & Yang, 2007), but the differences are as follows: (1) the new species has two bright red stripes extending from the crown to the end of the clavus (Fig. 13), the latter has two longitudinal orange-red stripes on the crown and pronotum terminating at the scutellum; (2) male pygofer of the new species has a small wart-like process at 2/3 length of the ventral margin (Fig. 19), the latter has a stout process at the middle of the ventral margin; (3) style of the new species has a single nipple-like process at the tip, slightly curved (Fig. 22), the latter has two processes at the tip.
