Host Plant. Bamboo ( Qiongzhuea communis ).

Distribution. China (Guizhou Province).

Remarks. We here transfer the species to Myittana (Benglebra) mainly based on the following characters: head with apex in profile truncate, head and thorax with longitudinal bands dorsally; male pygofer with stout spine arising from ventral margin, directed ventrocaudally; style apophysis apex bifid with two processes; aedeagus tubular and C-shaped in lateral view, gonopore apical on caudal surface. This species is similar to M. (Benglebra) biflaka sp. nov. (see remarks on M. (Benglebra) biflaka sp. nov.) above.
