This species is described in Averyanov et al. (2022), collected from southern Vietnam in March 2022. It is closest to D. pallens, but has villous fleshy rhizomes (almost glabrous in D. pallens), few-flowered inflorescences (many-flowered), almost circular epichile (rather broadly triangluar), a lip with a claw at its base (absent in D. pallens), and the flowers open at night and drop in the morning (keep flowering at day in most other Didymoplexis sp.).
