Eulophia bicolor described by Blume is an illegitimate name for a species that has generally been considered synonymous with E. nuda. The former should be recognized as a distinct species, as it differs in having different spur characteristics, a narrower column, and an anther cap with an elongated protuberance. It is here given a new name, E. lagaligo.
Keywords: Sulawesi, Lesser Sunda Islands, Indonesia, Monocots

Eulophia lagaligo Metusala, nom. nov.
Replaced name: Eulophia bicolor Blume (1859: 151), nom. illeg. (non Dalzell, 1851).
Type:—INDONESIA. Timor, Zippelius s.n. (holotype: L!—photo seen, barcode L0061229). Heterotypic synonym: Eulophia bicolor Blume var. celebica Smith (1922: 71). (Syntype: L!, barcode L0061231).
Diagnosis:— Eulophia lagaligo is morphologically close to Eulophia nuda, but differs in having a downwards-pointing spur formed by the lip and the column-foot (versus a backwards-pointing spur formed by the column-foot only, Fig. 4), a narrower column (2–2.5 versus 4–5 mm wide), and an anther cap with an elongated, horn-like protuberance (versus an anther cap with two short protuberances, Fig. 5).

Distribution:— The distribution of Eulophia lagaligo so far appears to be restricted to two islands in Wallacea. During the expedition in 2008, living plants were found in relatively open habitat in Cani Sirenreng, South Sulawesi at 100–600 m. Previous records of this taxon are from Gunung Pasangmalambe, South Sulawesi (Smith 1922) and Timor Island, Lesser Sunda islands (Blume 1859).
Etymology:— The specific epithet refers to La Galigo, a 14th century poetic text in the ancient language of the Bugis people from South Sulawesi, which has been recognized by UNESCO as Memory of the World documentary heritage, and is one of the most voluminous literary work in the world.
