03D487A6FFD7FFB0FF00FF4CFD89007A.taxon	distribution	Distribution and habitat Guzmania sanluisensis occurs in the montane cloud forests of “ San Luis del Nuevo Retiro ”, Cajamarca (northern Peru), where a variety of microhabitats exist. It grows epiphytically on tree trunks and branches, and can also be found on the forest floor, at an altitude of 2390 m. This species is associated with a diverse set of plant taxa characteristic of these ecosystems, including Magnolia manguillo Marcelo-Peña & F. Arroyo, Cedrela angustifolia DC., as well as species of Ficus, Miconia, Cavendishia, Hedyosmum, Weinmannia, Hieronyma, Piper, and Cyathea. Flowering has been observed in mid-March.	en	Rojas-Fernandez, Marisela Analu, Gouda, Eric J., Marcelo-Peña, José Luis (2025): Guzmania sanluisensis (Bromeliaceae; Tillandsioideae), a new species from the fragmented montane cloud forests of northern Peru.

03D487A6FFD7FFB0FF00FF4CFD89007A.taxon	conservation	Conservation status Guzmania sanluisensis is an extremely rare species with a very restricted distribution. After three botanical expeditions of three to four days each, only five individuals were recorded. Its habitat is severely threatened by deforestation, agricultural expansion, and grazing, factors that intensify fragmentation and loss of forest cover, in addition to the potential effects of climate change by altering precipitation and increasing the frequency of droughts. The extent of occurrence (EOO) cannot be accurately estimated because only one recording point is available, while the area of occupancy (AOO) is formally estimated at 4 km ², although the actual value is considerably lower (<0.1 km ²). Based on its presence in a single location, the low population abundance, and current threats, we propose its preliminary categorization as Critically Endangered (CR) under IUCN criterion B 2 ab (iii) (2024).	en	Rojas-Fernandez, Marisela Analu, Gouda, Eric J., Marcelo-Peña, José Luis (2025): Guzmania sanluisensis (Bromeliaceae; Tillandsioideae), a new species from the fragmented montane cloud forests of northern Peru.

03D487A6FFD7FFB0FF00FF4CFD89007A.taxon	etymology	Etymology The species epithet refers to San Luis del Nuevo Retiro, where the species was discovered. This locality is part of the montane cloud forests of northern Peru, rich in plant diversity, where new species have been recently reported (Marcelo-Peña & Arroyo, 2013; Reynel & Marcelo-Peña, 2025), suggesting that many more remain unknown to science. The authors hope that this designation will encourage conservation efforts in these forests, which are undergoing severe fragmentation due to agricultural and livestock expansion.	en	Rojas-Fernandez, Marisela Analu, Gouda, Eric J., Marcelo-Peña, José Luis (2025): Guzmania sanluisensis (Bromeliaceae; Tillandsioideae), a new species from the fragmented montane cloud forests of northern Peru.

03D487A6FFD7FFB0FF00FF4CFD89007A.taxon	discussion	Observations Guzmania sanluisensis is morphologically similar to G. xipholepis, but it is distinguished by several vegetative and reproductive characteristics (see table 1). The description of G. xipholepis was based on the online Encyclopedia of Bromeliads by Gouda et al. (2025).	en	Rojas-Fernandez, Marisela Analu, Gouda, Eric J., Marcelo-Peña, José Luis (2025): Guzmania sanluisensis (Bromeliaceae; Tillandsioideae), a new species from the fragmented montane cloud forests of northern Peru.
