Abstract
An undescribed species of Pinguicula (Lentibulariaceae), first collected in 1972 was recently rediscovered in the Arroyo Babarocos canyon, located in the Sierra Obscura region, in the municipality of Uruachi, Chihuahua, Mexico. This plant is described and illustrated as Pinguicula warijia. The taxon is compared with the related species P. oblongiloba and P. zamudioana, and a key to the species of P. section Orcheosanthus of western Mexico is provided, along with photographs, distribution map, and taxonomic discussion.

Pinguicula warijia Zamudio, Hern.Rend., M.Mata-Rosas & M.M.Salinas, sp. nov.
Similar to Pinguicula zamudioana but differs in having numerous, sessile, spathulate to elliptic-spathulate leaves (vs. 4–8(10) petiolate, oblong–elliptical to suborbicular leaves), upper calyx lip lobes ovate to elliptic (vs. triangular-lanceolate), lower calyx lip lobes triangular (vs. lanceolate), upper corolla lip lobes suborbicular to oblate (vs. oblong–elliptical to suborbicular), capsule botuliform (vs. subglobose), seeds 1–1.28 mm long, ca. 0.2 mm wide, surface slightly reticulate (vs. ca. 0.5 mm long, ca. 0.1 mm wide, surface reticulate).
Etymology:—The specific epithet honors the Warijó or Guarijó indigenous people, who inhabit this portion of the Sierra Madre Occidental in the municipalities of Chinipas, Moris, and Uruachi in the state of Chihuahua, as well as in the municipalities of Álamos, Quiriego, and Rosario in the state of Sonora. In addition, it is also the ethnic group to which our guide, Mr. Arnulfo Méndez, belongs. The word Warijó means “the people” or “the people that speak the Guarijía language”. Other names by which this ethnic group is known are Marakawe, Macoragüi, Varihio, Varohío, and warijío(a) (Porras 1997).
