    Telipogon leisberthvelezii (Orchidaceae: Oncidiinae), a new orchid species from the Cordillera del Cóndor in Ecuador
    (Springer Science and Business Media Deutschland GmbH, 2024-03-01)
    Telipogon leisberthvelezii Iturralde, M.M.Jiménez & H.Garzón, a new species of orchid, discovered in the Cordillera del Cóndor in southern Ecuador, is described and illustrated and its morphological similarities to other species are discussed. The new species is morphologically most similar to T. jostii (Dodson) N.H.Williams & Dressler but differs in the ellipsoid-obovoid petals with a bilobed base, the lip having a deltoid midlobe and dolabriform lateral lobes and a lower density of setae on the column. It is currently known from a single locality only, occurring as an epiphyte in lower montane forest.

    Telipogon villonacoensis (Orchidaceae: Oncidiinae), a new species with an unexpectedly wide distribution from the northern and central Andes of South America
    (Meise Botanic Garden, 2025-01-01)
    Background and aims – Telipogon is an orchid genus with a main diversity centre located in the tropical Andes. Some small-flowered Telipogon species, formerly classified under Stellilabium , remain poorly known. During recent fieldwork in southern Ecuador, an undetermined species of a miniature Telipogon was recorded and collected. We aimed to taxonomically identify the orchid and understand its phylogenetic relationships. Material and methods – We conducted field work in diverse parts of Ecuador and Peru, revised material deposited at various herbaria, and records available on iNaturalist. Furthermore, we extracted, amplified, and sequenced DNA sequences to evaluate the phylogenetic position of the undetermined species. Key results – The unidentified species turned out to be an undescribed Telipogon species, which we describe and name here as T. villonacoensis . It has also been recorded in Colombia and Peru, an unusually wide distribution for a Telipogon species. Telipogon villonacoensis is distinguished by its pale green to yellow flowers, the elliptic petals and lip, minute lobes and red coloration at its basal third. This species appears to have a patchy distribution and specialized habitat preferences, growing as an epiphyte in montane shrublands and forests. Although fewer than 200 individuals have been documented so far, and its habitats face ongoing threats, our conservation assessment indicates the species could be classified as not threatened. Phylogenetic analyses resulted in a well-resolved tree, in which T. villonacoensis is placed within the clade of the South American miniature Telipogon and sister to, but genetically distinct from, T. pogonostalix , though it is morphologically more similar to T. alexii , a species placed in another subclade of South American miniature Telipogon . Conclusion – Our results highlight the underestimated diversity and distribution range of miniature Telipogon and underscore the need for continued collaborative exploration and conservation in Andean ecosystems. These findings will contribute to a better understanding of orchid diversity and evolution of Telipogon species.

    Telipogon rojasiae (Orchidaceae, Oncidiinae), a new species from relict forests on the western slopes of the northern Peruvian Andes
    (Pensoft Publishers, 2025-01-01)
    Telipogon rojasiae , from the western Andean slopes of northern Peru, is described as a new species. Telipogon rojasiae is similar to Telipogon montufarianus , which is only known from southern Ecuador, but differs in its cream-yellow flowers heavily stained with red-vinaceous (vs. bright yellow flowers), the sub-rhombic to obovate petals (vs. elliptic petals), the number of veins in the petals (9–10 veins vs. 5 veins) and labellum (26 veins vs. 16–19 veins), and its sagittate callus (vs. widely subcordiform callus). We provide a description, illustrations, photographs, and information about the habitat of this new species. Furthermore, we discuss the identity and occurrence of morphologically similar species. The discovery of this new entity highlights the importance of preserving the relict forests of the western Andean slopes in north-west Peru and south-west Ecuador.
