Ituglanis bambui is endemic to Brazil, known from a single cave, Angelica Lapa, Angélica-Bezerra System, Paranã River basin, Alto Tocantins, municipality of São Domingos, Goiás. The area of occupancy is estimated at 5 km2. The cave is visited by many people who are not controled. Besides the trampling and silting of the river, the presence of the tourists causes the bats to move away, reducing the amount of guano and, consequently, the terrestrial arthropods that are part of the species diet. A decrease of the population (35%), in 10 years, was observed in this section of the cave, which may be related to the intense and uncontrolled visits. Therefore, Ituglanis bambui was categorized as Critically Endangered (CR) under the criterion B2ab (iii, v). As a conservation measure, visits in the cave should be suspended". [Google Translate]
