0398878ED2195625A017FC2E4826FA09.taxon	conservation	Conservation status — Following the criteria and categories of IUCN (2012), a preliminary status of Vulnerable (VU) is assigned (A 1 a + D 1). The new species deserves protection because its total area of occupancy is less than 200 km 2; population size is estimated to be fewer than 200 individuals (D 1); and we observed a reduction of the population mainly caused by human urbanization and habitat destruction (A 1 a). The suitable habitats for T. arequipensis on the xeric scrubland slopes in the Socabaya, Polobaya, Mollebaya and Quequeña districts are regarded as vulnerable because changes in annual rainfall, volcanic activity, exploitation of natural resources and uncontrolled urbanization, may all potentially reduce their extent.	en	Montesinos-Tubée, D.

0398878ED2195625A017FC2E4826FA09.taxon	discussion	Note — The new species is morphological similar to Tigridia raimondii Ravenna and T. philippiana I. M. Johnst. but is clearly distinguished by the white to pale white (or pale lilac) outer tepals with purplish maroon and dark yellow spots and stripes, and inner tepals with pale purplish and bluish spots and stripes. Moreover. it differs by having longer basal leaves and fruits, narrower and larger bracts and longer style branches.	en	Montesinos-Tubée, D. B., Pauca, A., Revilla, I.
