3.2. Koellensteinia dasilvae C.F.Hall & F.Barros in Hall et al. (2015: in press).

Type:—BRAZIL. Amapá: Serra do Navio, close to River Amapá, ex hort., 7 August 2013, Hall & Koch 1000 (holotype SP 473704)

Etymology:— Named after Jo"o Batista Fernandes da Silva, a prominent collector and orchidologist from Museu Paraense Emílio Goeldi, Pará, Brazil.

Distribution:— Northern Brazil: Amapá. TDWG code: 84 BRN-AP.

Taxonomic note:— This recently described species was considered by the authors as endemic to Amapá, Brazil. It was compared with Koellensteinia hyacinthoides , from which it does have several differences, but it was not compared with other species. Our study of the protologue shows clear similarities with K. carraoënsis that would render it to be a new synonym. It would not be a novelty if a taxon formerly recorded in the Guyanan countries to be confirmed in the Brazilian states bordering these.
