A new locality of Lecanorchis taiwaniana from Nam Ha National Protected Area, Luang Namtha Province, northern Laos is reported and a description of the species based on the Laos material is provided. Lecanorchis taiwaniana was known previously only from Japan and Taiwan. Considering that species of Lecanorchis are easily overlooked in the wild due to their short flowering season and dwarf habit, it is possible that L. taiwaniana is more widely distributed.
