A New Species of Stigmatodactylus (Orchidaceae) from West Papua Province, Indonesia, and the Rediscovery and Reinterpretation of S. gibbsiae

Year: 2026

Type: article

Abstract: Two species of Stigmatodactylus have recently been observed in the Arfak Mountains of West Papua Province, Indonesian New Guinea. One of these is clearly undescribed and is here described as Stigmatodactylus antennatus Schuit., Saputra & Wanma, a species uniquely characterised by the presence of a pair of antennae on the lip. The other is believed to be S. gibbsiae (Kores) Kores. This species was only known from the type material collected in the Arfak Mountains more than a century ago, in 1913. There are, however, significant discrepancies between the protologue and the material recently found. We interpret these discrepancies as misinterpretations of the poor type material of S. gibbsiae, and provide images based on fresh material. An identification key to the four species of Stigmatodactylus in New Guinea is included.
