| الوصف: | Background: The subtribe Oncidiinae represents one of the most diverse orchid groups in CostaRica, comprising 186 species across 33 genera. Questions: Despite their already known great richness, is it possible that the diversity of smaller and less conspicuous genera remains poorly documented, especially in regions where collecting efforts have been limited? To address the diversity of the genus, what is the most suitable circumscription of Notyliopsis? Taxa: Orchidaceae, Macroclinium geniculatum Pupulin & Bogarín, sp. nov., Notyliopsis beatricis P.Ortiz. Study sites: Reserva Biológica Guaitil, Pejibaye, Costa Rica; Calle La Mina, Tayutic, Costa Rica Results: As part of the ongoing initiative to update the Flora costaricensis: Orchidaceae, we describe a new species of Macroclinium and report the first national record of Notyliopsis, both members of the Oncidiinae. Conclusions. Macroclinium geniculatum is described, illustrated, and compared with the similar M. confertum Pupulin, from which it mainly differs in the free lateral sepals (vs. basally connate), the petals with three large rose-purple blotches (vs. numerous dots), the sigmoid column (vs. straight), and the claw of the lip being abruptly geniculate at the middle (vs. straight). Notyliopsis beatricis, previously known only from Chocó, Colombia, i 49 s newly recorded for the Costa Rican flora. We used molecular data to reassess the phylogentic position of Notyliopsis and to test the previously proposed hypothesis that Santenderella should be included within this genus. For both species, detailed morphological descriptions and illustrations based on Costa Rican specimens are provided. These findings contribute to the ongoing updating of the inventory of the Oncidiinae in the country towards the completion of Flora costaricensis. |
