A new species of Discochiton Hodgson & Williams, 2018 collected on culms of Bambusa sp. (Poaceae) in Myanmar is described and illustrated. The new species is morphologically similar to D. expansum (Green, 1896), but distinct from it in having the legs four or five segmented, the preopercular pores associated with all four clear areas, and the 10–16 stigmatic spines on each cleft; in D. expansum, it has the legs reduced to single-segmented leg stub, the preopercular pores associated with two or three clear areas, and the 3–7 stigmatic spines.
