Pimelodella spelaea is endemic to Brazil and is known only from the type locality at the Terra Ronca State Park, São Bernardo cave, in São Domingos, Tocantins high river, GO. Despite the great effort of collection, the species is only found in the accessible areas of the São Bernardo cave. It is estimated that the total population size is a few hundred, reaching a maximum of 1,000 individuals. The cave in question presents unordered tourist access and is in the limit of the State Park, which can lead to irreversible disturbances to the environment. In addition, all the river springs that cross the park's cave are located outside the park, in an area with extensive agriculture and monoculture, silting up and polluting the rivers, which can pose a threat to the entire population. The Area of Occupancy (AOO) was calculated at 17.5 km². Considering AOO less than 500 km ², the continuous decline in habitat quality (with the contribution of harmful allochthonous material, especially agrotoxic material), and number of locations ≤ 5, Pimelodella spelaea was categorized as Endangered (EN) by criterion B2ab (iii). Studies are recommended to define the minimum area and the spatial protection limit of the species. [Google Translate].
