Thismia puberula was described in Nuraliev et al. (2015), collected from Chu Yang Sin National Park in southern Vietnam. It is primarily distinct from its closest relatives T. angustimitra, T. mirabilis, T. mucronata and T. okhaensis by its dome-shaped, puberulent annulus covering the floral tube beneath the mitra-like inner tepals. The combination of other features furthermore distinguishes it from their sister taxa.
