            <p> Etymology. The specific epithet  montalvaniensis refers to the city of Montalvânia, where the new species was collected. </p>
            <p> Remarks.  Pectenoniscus montalvaniensis n. sp. differs from  P. angulatus by the number of articles in the antenna flagellum (3 versus 5 in  P. angulatus ), and by the shape of male pleopod 2 endopod (apex with lobe directed inwards versus apex with plate-like appendage in  P. angulatus ) and exopod (triangular versus rectangular in  P. angulatus ). In relation to  P. liliae ,  P. montalvaniensis n. sp. differs by the triangular shape of antennal lobes (versus quadrangular in  P. liliae ), by the number of aesthetascs in the antennula distal article (8 versus  P. liliae : 9) and the shape of male pleopod 2 endopod (apical portion chela-shaped with two triangular lobes in  P. liliae ) and exopod (ovoid in  P. liliae ). </p>
            <p> Habitat and ecological remarks.  Pectenoniscus montalvaniensis n. sp. was collected in a cave associated with an isolated limestone outcrop(Fig.4A) in relation to the main massif occurring in the area. Although there are many caves in the region, only a few were sampled, suggesting that new populations of  P. montalvaniensis n. sp. potentially can be discovered in the future in this region. The original name of the cave where this species was found (Abrigo da Ema - “Ema shelter” - in Portuguese) was attributed by archaeologists due to the ancient rock engravings on the cave wall (Fig. 4B). The cave presents aphotic conduits, the specimens were found concentrated on the cave floor (around 20 specimens), close to moist areas, where the humidity came from dripping speleothems. The main cave conduit seems to be trespassed by water f lows during strong rains, which brings organic matter to the cave interior (especially vegetal debris). A few bat guano piles were observed in the cave, but no isopod specimens were found associated with them. Indeed, several individuals of  P. montalvaniensis n. sp. were found close to roots, which were frequent on the cave floor (Fig. 4C). The dark gut content observed in the living specimens indicate they were feeding on dark brown organic debris, as plant material or eventually dead root masses. The external environment surrounding the cave is altered, especially by the replacement of native vegetation by pastures (Figs. 21, 22A). However, considering that this cave seems not to be frequently visited by humans, no direct impact for the species was detected. </p>

            <p> Etymology. The specific epithet  juveniliensis refers to the municipality of Juvenilia, where the new species was collected. </p>
            <p> Remarks.  Pectenoniscus juveniliensis n. sp. differs from  P.angulatus and  P. liliae by the dorsal granulation pattern (two rows on all the pereonites versus three rows on the first pereonite and two on the others in  P. angulatus and  P. liliae ), the shape of male pleopod 1 exopod (apex acute versus round in  P.angulatus and  P. liliae ), and the shape of male pleopod 2 exopod (sub-triangular versus rectangular in  P. angulatus and ovoid in  P. liliae ). Moreover,  P. juveniliensis n. sp. differs from  P. montalvaniensis n. sp. by the dorsal granulation pattern, by the number of aesthetascs on antennula (9 versus 8 in  P. montalvaniensis n. sp. ), by the shape of male pleopod 1 exopod with acute apex (versus round apex), by the shape of male pleopod 2 exopod with triangular shape (versus trapezoid) and by the male pleopod 2 endopod apex distal margin rounded, without apical lobe; two subapical lobes on inner margin (versus apex with lobe directed inward and subapical denticles projected outward). </p>
            <p> Habitat and ecological remarks. Specimens of  P. juveniliensis n. sp. were found in Gruta do Tabuleirinho (also regionally known as “Lapa Grande” cave), which comprises the biggest known cave in the municipality (Figs. 7A, 21, 22B). This cave presents a single large entrance (40 m high) (Fig. 7B). From the entrance onwards, the cave develops into a voluminous conduit (Fig. 7C), which is mostly dry. In this conduit, although several bat guano piles were observed, no specimens of  P. juveniliensis n. sp. were found associated. Considering that the visit to the cave occurred in the rainy season, many travertine pools were filled with water, but no specimens were found in this conduit. Near the end of this main conduit, a lateral ascent leads to an upper chamber, which is moister and warmer than the lower part of the cave. Furthermore, it is extremely oligotrophic, and the organic debris consisted of rare and old bat guano piles. All specimens of  P. juveniliensis n. sp. were found in this upper chamber, especially walking on moistened speleothems, as stalagmitic f loors and flowstones (Fig.7D). Despite the lack of visible organic matter (bat guano), the dark gut content observed in the living specimens indicate they are feeding on some organic resources occurring in this upper level. Since this cave is voluminous, it is difficult to find specimens, however thorough searches have revealed that they are not rare along the cavity (we observed at least 20 individuals in a single visit to the cave). Furthermore, other specimens of  Pectenoniscus were found in two other caves in the area (Gruta do Zé Prefeito and Gruta do Fóssil caves), however, only females were found, and since male characters are important to define the species, we choose not to assign them to the herein described species. Another described troglobitic species found in this cave is the unusual hydrometrid hemipteran  Spelaeometra gruta (Polhemus and Ferreira, 2018) . Gruta do Tabuleirinho cave presents obvious signs of human visitation, but currently only a few visitors have been entering the cave, according to local residents. Regarding the external landscape, it is composed of secondary forest under regeneration (close to the outcrop), and pastures (Fig. 22B). </p>

Pleopod 3–5 exopods (Fig. 9F–H) subquadrangular, bearing four-five setae on outer margin.</p>
            <p> Etymology. The specific epithet  iuiuensis refers to the mountain range where the new species was collected, Serra de Iuiú. </p>
            <p> Remarks.  Pectenoniscus iuiuensis n. sp. differs from  P. angulatus by the number of aesthetascs on antennula (10 versus 8 in  P. angulatus ), the number of articles in the antenna flagellum (3 versus 5 in  P. angulatus ), the shape of male pleopod 1 exopod (both with round apex, although lateral margin is sinuous versus straight in  P. angulatus ) and the shape of male pleopod 2 endopod. From  P. liliae ,  P. iuiuensis n. sp. differs by the number of aesthetascs on antennula (10 versus 9 in  P. liliae ), the shape of male pleopod 1 exopod (lateral margin sinuous versus straight in  P. liliae ), the shape of male pleopod 2 exopod (subrectangular versus ovoid in  P. liliae ) and the shape of pleopod 2 endopod. From  P. montalvaniensis n. sp. and  P.juveniliensis n. sp. ,  P. iuiuensis n. sp. differs by the well-developed epimera; by the number of aesthetascs on antennula (versus 8 and 9, respectively); the shape of male pleopod 1 exopod triangular with sinuous lateral margin (versus straight, in  P. montalvaniensis and  P. juveniliensis ); and by the subrectangular male pleopod 2 (subrectangular versus trapezoid and triangular, respectively). </p>
            <p> Habitat and ecological remarks. Specimens of  P. iuiuensis n. sp. were found in Baixa da Fortuna cave (municipality of Iuiú, state of Bahia), which comprises a relatively small limestone cavity (Fig. 21). The cave is surrounded by vertical outcrops (Fig. 10A, B), requiring one to climb in order to reach the entrance (Fig.10C). The single cave conduit presents a small autogenic drainage that arises in the innermost part of the cave (upstream) and flows toward the entrance, then sinking on the opposite side of the conduit (downstream) after the entrance. Hence, the cave entrance is laterally located in relation to this drainage. Individuals of  P. iuiuensis n. sp. were observed walking on the cave sediments, especially close to the stream, always in the deeper portions of the cave. Few specimens were found despite efforts to make a thorough search in the cave due to its small dimensions. Another troglobitic species inhabiting this cave is the bochicid pseudoscorpion  Spelaeobochica iuiu (Ratton et al., 2012) . The external area surrounding the cave presents a well-preserved forest (Figs.10A, 22C), although pastures are observed a few kilometers from the cave (about 2 to 3 Km). No signs of human visitation were observed, probably due to the hard access to the cave; in this sense the cave is preserved. </p>

            <p> Etymology. The specific epithet  “ carinhanhensis ” refers to the municipality of Carinhanha (state of Bahia), where the new species was collected. </p>
            <p> Remarks.  Pectenoniscus carinhanhensis n. sp. differs from  P. angulatus and  P. liliae by the number of aesthetascs on antennula (11 versus 9 in  P.angulatus and  P. liliae ), by the sternal margin of male pereopod 7 ischium (straight versus with a triangular projection in  P.angulatus and convex margin in  P.liliae ), the shape of male pleopod 1 exopod (sinuous lateral margin versus straight in  P.angulatus and  P. liliae ), the shape of male pleopod 2 exopod (subtriangular versus rectangular in  P.angulatus and ovoid in  P. liliae ) and the orientation of endopod (twisted versus straight in  P.angulatus and  P. liliae ).  Pectenoniscus carinhanhensis n. sp. is similar to  P. iuiuensis n. sp. in the triangular shape of male pleopod 1 exopod, with round apex and sinuous lateral margin, however in  P. iuiuensis n. sp. the exopod seems to be directed backward while in  P. carinhanhensis n. sp. it is directed outward. </p>
            <p> Habitat and ecological remarks. Specimens of  P. carinhanhensis n. sp. were found in three caves of the Água Clara Cave System (ACCS) (Figs. 21, 22D). This system is formed by four limestone caves interconnected by an intermittent drainage (Gruna da Água Clara, Gruna dos Índios, Lapa dos Peixes I, and Lapa dos Peixes II – Fig. 13A). Two of the caves that compose the system are the tenth and the fourteenth biggest caves in Brazil, respectively (Água Clara Cave – 13,880 meters and Lapa dos Peixes cave – 9,320 meters long), while the other two are smaller (Gruna dos Índios cave – 570 meters and Lapa dos Peixes II – 2,100 meters). Together these four caves account for 25.85 km of subterranean passages. In general, the caves present wide vadose conduits (Fig. 13C, E) through which a huge amount of water f lows during the rainy periods, noticeable by the massive plant debris (such as tree trunks) observed at several points within the caves (Fig. 13D). Although the water f lows along the caves only in the rainy periods, flooded chambers occur in some areas even in the dry periods, as in the Lapa dos Peixes II cave (Fig. 13E). Individuals of  P. carinhanhensis n. sp. were observed in several areas along the caves, always associated with moist substrates (Fig. 13F). Most specimens (around 90% of the observed specimens in the ACCS) were found in Água Clara cave (Fig. 13C), which is the first (upstream) and biggest cave of the ACCS. The large number of specimens observed in this cave (dozens of individuals) can be related to its high humidity throughout the whole year, due to its dimensions. Few specimens (less than 10) were observed in Lapa do Índio cave, where they were restricted to a few moistened areas (a considerable extension of the cave was dry when the sampling was carried out). Finally, specimens were also collected in Lapa dos Peixes II cave, the last (downstream) cave of the ACCS. Although this species was not found in Lapa dos Peixes cave I, the possibility of its occurrence in this cave is not excluded, since only part of this cave was inventoried. In this sense it is plausible to assume that this species occurs in the whole ACCS. Specimens of  P. carinhanhensis n. sp. were observed in very distinct conditions regarding the presence of visible organic matter. In some areas they were encountered close to vegetable debris, while in the deeper portions of the caves (especially in Água Clara cave) organisms were found in areas completely devoid of visible organic resources. The ACCS also shelters six other troglobitic species: the isopod  Xangoniscus aganju Campos-Filho, Araujo and Taiti, 2014 , the harvestmen  Giupponia chagasi Pérez and Kury, 2002 (Kury and González, 2002), the whip spider  Charinus troglobius Baptista and Giupponi, 2002 , the earwig  Mesodiplatys falcifer Kamimura and Ferreira, 2018 , the snail  Spiripockia punctata Simone, 2012 and the fish  Trichomycterus rubiolli Bichuette and Rizatto, 2012 . The native habitat surrounding the caves consists of the Caatinga formation, which is severely altered, especially due to the removal of the original vegetation for charcoal production, as well as for the establishment of pastures and monocultures (Fig. 13B). The caves seem to be only visited by speleologists, so that the impacts of trampling over the cave fauna is negligible. </p>

            <p> Etymology. The specific epithet  “ santanensis ” refers to municipality of Santana, where the new species was collected. </p>
            <p> Remarks.  Pectenoniscus santanensis n. sp. differs from  P.angulatus and  P. liliae by the dorsal granulation pattern (two rows in all the pereonites versus three rows in the first pereonite and two in the others on  P. angulatus and  P. liliae ), the number of aesthetascs on antennula (6 versus 8 in  P. angulatus and 9 in  P. liliae ), the sternal margin of male pereopod 7 ischium (straight versus with triangular projection in  P. angulatus and convex in  P. liliae ), the shape of male pleopod 2 exopod (sub-triangular versus rectangular in  P. angulatus and ovoid in  P. liliae ) and the orientation of male pleopod 2 endopod (twisted versus straight in  P.angulatus and  P. liliae ).  Pectenoniscus santanensis n. sp. is similar to  P. carinhanhensis n. sp. in the shape of male pleopod 2 exopod subtriangular and by the straight sternal margin of male pereopod 7 ischium; however it differs by the number of aesthetascs on antennula (6 versus 11 in  P. carinhanhensis n. sp. ) and the shape of male pleopod 1 exopod (straight lateral margin versus sinuous in  P. carinhanhensis n. sp. ). </p>
            <p> Habitat and ecological remarks. Gruta do Padre represents one of the largest known caves in Brazil (16,400 meters of horizontal projection – Fig. 16A), currently considered the fifth longest in total extension in the country (Rubbioli et al., 2019) and is part of one of the most extensive subterranean hydrological systems in Brazil. It presents three distinct levels with a river flowing in the lowest one (Fig.16C). The upper level is accessed through the cave main entrance (Fig. 16B), and is connected to a set of ample galleries, most of which were enlarged by collapsing processes. The specimens were found on the f loor, walking on a moist mud layer, in a voluminous chamber located in a deep portion of the upper level, around 500 meters from the main cave entrance (Fig.16D). Although far from the river, the substrates were moist due to the high humidity in the chamber provided by dripping speleothems. Considering the huge dimensions of the cave, a thorough search was only performed in few areas, therefore the low number of registered specimens (less than 10 – some of them were not collected) does not necessarily indicate that the species present low population density. Gruta do Padre cave also presents other described troglobitic species, such as the beetle  Coarazuphium tessai (Godoy and Vanin, 1990) , the amphipod  Spelaeogammarus santanensis Koenemann and Holsinger, 2000 and the millipede  Phaneromerium cavernicolum Golovatch and Wytwer, 2004 . Currently, the external environment surrounding the cave is altered, especially by the removal of the native vegetation for pastures (Figs. 21, 22E). On the other hand, considering the huge extension of the cave and the fact that only a few speleologists visit it each year (especially due to the difficult accesses inside the cave), the inner portion of the cave is well preserved. </p>

            <p> Etymology. The specific epithet  “ morrensis ” refers to the municipality of Morro do Chapéu, where the new species was collected. </p>
            <p> Remarks.  Pectenoniscus morrensis n. sp. differs from  P. angulatus and  P. liliae by the dorsal granulation pattern (two rows in all the pereonites versus three rows in the first pereonite and two in  P. angulatus and  P. liliae ), the number of aesthetascs on antennula (6 versus 8 in  P.angulatus and 9 in  P. liliae ), the shape of male pleopod 2 exopod (subtriangular versus rectangular in  P. angulatus and ovoid in  P. liliae ) and the orientation of endopod (twisted versus straight in  P. angulatus and  P. liliae ).  Pectenoniscus morrensis n. sp. is similar to  P. santanensis n. sp. in the number of aesthetascs on antennula, by the shape of male pleopod 1 exopod triangular with lateral margin straight and round apex; and by the shape of male pleopod 2 exopod subtriangular, however, it differs by the shape of male pleopod 2 endopod. </p>
            <p> Habitat and ecological remarks. Specimens of  P. morrensis n. sp. were found in  Gruta dos Brejões cave, located in the municipality of Morro do Chapéu (state of Bahia) (Fig. 21). The cave presents an impressive entrance of 106 meters high (Fig. 20C) followed by a chamber with similar dimensions. The cave extends 6,570 meters, but it was longer in the past, trespassing a massive limestone outcrop (Figs. 20C, D, 21F). During the karst evolution in the area most of its original conduit collapsed, creating a canyon (Fig. 20D). In fact, the cave presents two conduits (Gruta I e II) laterally connected in some areas. The upper level is predominantly dry and presents huge skylights and impressive speleothems (Fig. 20E). On the other hand, the lower level is moist due to the presence of the Jacaré river, which arises among collapsed blocks (around 750 meters from the main entrance) and covers a considerable extension of the lower level. There are ponds connected to the river in some areas of the lower level in which a thin layer of calcite is deposited on the water surface. When the water level drops, such pieces of calcite are deposited on the muddy sediment of the riverbanks. Individuals of  P. morrensis n. sp. were found under those calcite fragments walking on the substrate (Fig. 20F). The organic resources observed in this area were a few small fragments of vegetal debris, transported to the cave by the river. This river shelters the unique troglobitic Porifera from Brazil (the sponge  Racekiela cavernicola Volkmer-Ribeiro, Bichuette and De Sousa Machado, 2010 ), which is extremely abundant on the riverbed, presenting hundreds of individuals. Another troglobitic species inhabiting the cave is the spider  Ariadna aurea Giroti and Brescovit, 2018 . The external landscape surrounding the cave is altered. Although the upper part of the limestone outcrop is well preserved in some areas (due to the difficulties of access), the Jacaré river valley is severely altered especially because it constitutes the only water source in the region. There are many crops grown in the valley (Fig. 22F). </p>
