Figs 13–23 View FIGURES 13–23 , 24–28 View FIGURES 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 View FIGURES 13–23 ). Face yellowish white, eyes yellowish-brown ( Fig. 17 View FIGURES 13–23 ). Pronotum with two additional bright red stripes on each side near the lateral margin ( Fig. 15 View FIGURES 13–23 ). 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 View FIGURES 13–23 ). 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 View FIGURES 13–23 ), apex of head truncate in lateral view, with face flat ( Fig. 16 View FIGURES 13–23 ). Width of face including eyes approximately 0.8 times length (1: 1.2) ( Fig. 17 View FIGURES 13–23 ). 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 View FIGURES 13–23 ). Forewing length is about 4.5 times as long as the widest part (4.49: 1) ( Fig. 13 View FIGURES 13–23 ).

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 View FIGURES 13–23 ). Valve triangular, subgenital plate elongated ( Fig. 23 View FIGURES 13–23 ).Style twisty, apical nipple-like process pointing outwards ( Fig. 22 View FIGURES 13–23 ). Connective V-shaped, outer margin of base concave inward, apex arc-shaped ( Fig. 21 View FIGURES 13–23 ). Aedeagus tubularly curved, stout at base, tapering towards tip, gonopore at the apex ( Fig. 20 View FIGURES 13–23 ).

Female genitalia. Sternite VII with anterior margin nearly straight, lateral margin posteriorly convergent, posterior margin concave, slightly bulging in the middle ( Fig. 28 View FIGURES 24–28 ). First valvula weakly curved with strigate sculpture extended to dorsal margin, slightly wider at the apex 1/3, apically tapering ( Figs 24, 25 View FIGURES 24–28 ). 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 View FIGURES 24–28 ).

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. View FIGURES 13–23 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 View FIGURES 13–23 ), 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 View FIGURES 13–23 ), the latter has two processes at the tip.
