Body length: male: 5.45–5.62 mm. (n=6) Coloration. Body yellowish white. Crown yellowish-white, with two longitudinal orange-red stripes extending from the top of head backwards to the lateral margin of the scutellum, which becomes distinctly lighter from basal margin of scutellum (Figs 1, 3). Face yellowish white, eyes black (Figs 4, 5). Pronotum with two additional yellowish stripes on each side near lateral margin (Fig. 3). Forewing with dark-brown longitudinal stripe on commissural margin, extended along entire length (Fig. 1). Costal margin with irregular light brown spot near R 2+3, outer cells and medial area of third cell with another dark brown spot (Figs 1, 3). Legs yellowish white.
Head and thorax. Anterior margin of crown narrowly convex, median length slightly less than width between the eyes (1: 1.02) (Figs 2, 4), apex of head truncate in lateral view, with face concave (Fig. 4). Width of face including eyes approximately 1.2 times length (1:0.85) (Fig. 5). Pronotum width slightly wider than width of head including eyes (1.16:1), length longer than mid-length of crown (1.46: 1) (Fig. 3); Forewing length is about 5 times as long as the widest part (4.94:1) (Figs 1, 2).
Male genitalia. Pygofer very long and narrow in lateral view, with many long setae in distal half, lamellar projection arising from ventral margin near apical third giving rise to long, thick spine extended distad, tapering toward apex (Figs 6, 7). Valve triangular, subgenital plate broad in middle and bluntly rounded at tip (Fig. 12). Style slender, with finger-like process at tip extended obliquely posterolaterad, subterminal part with elongate setae on inner side (Fig. 11). Connective V-shaped, outer margin of base slightly flat, apex cylindrical (Fig. 8). Aedeagus sub-tubular, robust at base, slightly narrower at middle, tapering at tip (Figs 8–10).
Material examined.

Remarks. The new species is most similar to M. (B.) ventrospina (Chen & Yang, 2007), but the differences are as follows: (1) forewings of the new species with a dark-brown longitudinal stripe on the commissural margin (Fig. 1), the latter lacks the stripe on the forewing; (2) male pygofer of the new species has a lamellar projection and a long spine (Figs 6, 7), the latter has a short, broad spine; (3) style of the new species has a single finger-shaped process at the tip (Fig. 11), the latter has two processes.
