SUMMARY:

Invertebrates are at imminent risk of extinction due to anthropogenic pressures, lack of knowledge of their diversity and dislike by a large part of society. In the case of subterranean fauna, made up of unique terrestrial and aquatic invertebrates, the lack of knowledge is even greater. Some freshwater invertebrates from the caves of Rio Grande do Norte, in northeastern Brazil, are unique because they are oceanic relicts, among them the isopods of the Cirolanidae family, made up of endemic taxa from the Jandaíra Formation that have not yet been described. With at least two main lineages coexisting in the region that have not yet been described. This study aimed to describe, through integrative taxonomy, a new genus composed of four allopatric species of troglobitic cirolanids, and to provide information for the conservation of these crustaceans from the Caatinga. This integrative approach involved tools, traditional taxonomy and morphometrics, to delimit these species. We analyzed the physicochemical characteristics of the biotope of the type locality. As an environmental education strategy, we applied semi-structured questionnaires to investigate the perception of elementary school pupils in the vicinity of karst regions about the underground environment and its diversity. In this study, a detailed morphological description of Gen. nov. and its new species is provided, consisting of the more elongated isopods with a wider, torpedo-shaped anterior part. A detailed morphological description is provided for four caves and a karst spring, Três Lagos cave and the karst spring of Olho d'Água do Tetéu, Crotes cave, Pedra Lisa and Olho d'Água do Cedro. In the type locality, Três Lagos Cave, the abundance of the species had a significant correlation with oxidation potential, depth, chemical oxygen demand and pH. Environmental awareness was significant among the students in relation to the living beings that inhabit caves, but awareness of the importance of conservation measures for caves and their invertebrates was significantly altered. In this way, the inclusion of activities such as visits could help to change students' perceptions and weaken the negative perception of caves and invertebrates.
