SALAZAR, Gerardo A. et al. Rodriguezia vasquezii (Orchidaceae: Oncidiinae), an addition to the Peruvian flora. Rev. Mex. Biodiv. [online]. 2025, vol.96, e965500.  Epub 11-Nov-2025. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2025.96.5500.

Rodriguezia vasquezii, previously known only from Bolivia, is recorded for the first time in Peru on the basis of recently collected material in 2 natural protected areas (Área de Conservación Privada La Pampa del Burro, Department of Amazonas and Bosque de Protección Alto Mayo, Department of San Martín). A description based on the Peruvian material is provided, and the species is illustrated with color photographs in habitat and of details of its vegetative and floral morphology. Its phylogenetic relationships are assessed analyzing DNA sequences of a nuclear marker (ITS) and another from plastids (a fragment of the gene matK). A distribution map shows its known distribution, and its morphological differences from closely related species are contrasted in a table. It is clarified that the holotype of R. vasquezii is housed at SEL, not MO as indicated in the protologue, and a photograph of such specimen and another of the original illustration are reproduced to facilitate future comparisons.
