Abstract
Tillandsia tequilana, a new species from the state of Jalisco, Mexico, is described and illustrated. The proposed species is compared to T. aguascalientensis, T. moronesensis, and T. schusteri, taxa with some morphological similarities. Tillandsia tequilana differs from these species in the shape and size of the leaf sheath, spikes and floral bracts, in the shape of the sepals, and also in the flowering time. Images and a distribution map of the new species are included.

The new species is similar to Tillandsia aguascalientensis but differs in the shape (triangular to ovate vs. elliptic) and size of the leaf sheath (4.0–5.0 × 3.0–3.5 vs. 7.0–12 × 4.0–7.0 cm), in the shape (narrowly oblong vs. elliptic) and width (1.0–1.5 vs. 2.5–4.0 cm) of the spikes, in the shape (oblong to elliptic vs. lanceolate) and size (2.5–3.2 × 1.2–1.5 vs. 3.9–4.2 × 1.5–2.0 cm) of the floral bracts, and in the width of the sepals (0.4–0.5 vs. 0.9–1.1 cm).

Etymology:—Specific epithet refers to the municipality of Tequila, Jalisco, where the new species was discovered.
