Abstract

A new species, Lecanorchis tabugawaensis Suetsugu & Fukunaga, sp. nov. from Yakushima Island, Kagoshima Prefecture, Japan, is described and illustrated. Lecanorchis tabugawaensis is similar to L. taiwaniana, but it is easily distinguished by the straight column, the glabrous status of the base of the column, the almost entire and narrow labellum morphology, the shorter part of the column fused with the labellum and the glabrous status of the apical part of the adaxial labellum surface. The new species appears to be restricted to two locations, each consisting of only dozens of mature individuals, and is assessed as Critically Endangered [CR D1] according to IUCN Red List Categories and Criteria.
