Additional material examined.

Distribution. China ( Yunnan) ( Fig. 6 View FIGURE 6 ), Thailand, Laos ( Itoh 1995).

Remarks. Newly recorded for China. One female of M. ( M.) tuberculipennis obscura Itoh, 1995 and one male of M. ( M.) tuberculipennis Fairmaire, 1891 were collected in the same place Yangbi County of Yunnan province (see additional material examined). We therefore propose that M. ( M.) tuberculipennis obscura should be elevated to species status as M. ( M.) obscura Itoh, 1995 . The two species can be separated by the shape of the clypeus (moderately bilobate in M. ( M.) tuberculipennis while arcuate in M. ( M.) obscura ), and by the shape of the dorsal and ventral branches of the parameres (thin in M. ( M.) tuberculipennis while thick and expanded in M. ( M.) obscura ) ( Figs. 5a View FIGURE 5 ̄f).
