DISTRIBUTION: Jorottui ipuanai , sp. nov., is currently known from only four caves (Bañaderos Cave and an unnamed cave 100 m away from it, El Vainito Cave, and La Perrita Cave) in the Serranía de Bañaderos, a mountain range in the upper basin of the Camarones River in the La Guajira Department of northeastern Colombia (figs. 1A–C, 2, 3).

NATURAL HISTORY: Jorottui ipuanai , sp. nov., is an obligate troglobite that exhibits several troglomorphic characters such as depigmentation, thin cuticle, lack of ocelli, and elongated appendages. Several other arachnid taxa inhabit the same caves, e.g., the agoristenid harvestman, Avima wayuunaiki García et al., 2022 , the sicariid spider, Loxosceles guajira Cala-Riquelme et al., 2015 ( Cala-Riquelme et al., 2015; García et al., 2022), and an undescribed species of Charinus Simon, 1892 , whip spider. The caves in which J. ipuanai has been collected have not been thoroughly documented or included in the national cave record of Colombia ( Instituto Alexander von Humboldt, 1998). However, the area in which they are situated was recently incorporated into a protected area.
