Summary
Szlachetko D. L., Baranow P., Nowak S. & Archila F. 2017. Notes on the genera of the Eltroplectris-Pteroglossa com­plex (Orchidaceae-Orchidoideae-Spiranthinae) with description of four new species from South America. – Phyton (Horn, Austria) 57 (1–2): 1–9, with 5 figures.*

Seven genera of the Neotropical Eltroplectris-Pteroglossa group (Orchidaceae-Orchidoideae-Spiranthinae) are ac­cepted and briefly characterized. Four new species are described and illustrated: Ochyrella jatataensis Szlach., Baranow & S. Nowak from Bolivia, O. sztolcmaniana Szlach., Baranow & S. Nowak and Eltroplectris jelskiana Szlach., Baranow & S. Nowak, both from Peru, and Callistanthos pignalii Szlach., Baranow & S. Nowak from Brazil. A new combination in the genus Callistanthos, C. claudiae (Archila) Archila & Szlach. is proposed.
