DIAGNOSIS. — Almost uniform light yellowish brown ( Fig. 2H ; 13A ; 14A ). Hind wings slightly longer than forewings. Comb of tegminal Sc with 6-7 branches ( Fig. 13A ). Darkened bases of spines of hind tibiae ( Fig. 4D ). Male genitalia as in Figure 13 B-D. Apex of ovipositor drilling with large teeth on hind and ventral surfaces ( Fig. 14B, C ). This species resembling M. kongtumensis in size and shape, but distinguished by the pronotum and genitalia. In this species, the prosternum is dark at the edges and light in the middle, but that of M. kongtumensis is unicolor ( Fig. 2E, F, H ). Pseudepiphallic lophi of this species bear two semicircular-like projections apically, while that of M. kongtumensis do not ( Fig. 9 B-D; 13B-D).

DISTRIBUTION. — China (Fujian, Guangdong, Guangxi, Hunan, Zhejiang).

DESCRIPTION
