Describes by Nuraliev et al. (2014) from a forest near Boa Loc Town in southern Vietnam. It shows similarity with T. angustrimitra and T. mirabilis, but has short upright appendages appressed to each other froming a mucro. It lacks foveae (small depressions) at the top of the mitre, formed by the inner tepals. Also very similar is T. submucronata, found much later in Thailand (Chantanaorrapint et al. 2019).
