Host Plant. Bamboo.

Distribution. China (Guizhou, Yunnan).

Remarks. This species is similar to M. (Benglebra) alami but differs as follows: (1) crown and pronotum with reddish orange stripes (crown and pronotum with a pair of yellow brown stripes in M. (Benglebra) alami ); (2) male pygofer with ventral process more dorso-posteriorly bent (male pygofer with ventral process more strongly curved posteriorly near base in M. (Benglebra) alami ); (3) dorsal margin of aedeagus less extensively serrated, shaft short (dorsal margin of aedeagus more extensively serrated, shaft much longer in M. (Benglebra) alami ).
