Lateral field with two longitudinal veins that may or may not converge, but are usually connected through secondary veins and rarely completely parallel and isolated from one another throughout their extension. Ecological remarks. Specimens of Endecous infernalis n. sp. were found in Baix„o da Canoa cave, located in the municipality of Coribe, and in other two cave systems: the Gruna da Água Clara cave system (ACCS) and Gruna do Pedro Cassiano I cave (Fig. 29), both located in the municipality of Carinhanha, southwestern Bahia state, Brazil. The Água Clara cave system represents a set of functionally interconnected caves of approximately 24 km of extension. It is composed of four limestone caves trespassed by an intermittent stream, active during the austral summer (October until March) (Souza-Silva et al. 2021). The Gruna do Pedro Cassiano I cave (Fig. 29), in turn, is a single 2.660-meter-long cave that does not belong to the ACCS, but it is located near that system (approximately 4 km in a straight line). The Baix„o da Canoa cave was only recently discovered, so it was not yet properly explored. It is safe to say, however, that the surveyed conduits have at least 1.5 km of extension. This cave has a single known entrance, which leads to a crawling conduit that connects to a wide main chamber, representing the main cave conduit, which has an intermittent drainage active during rainy periods. Differently from what is usually observed for most of the Endecous species occurring in Brazilian caves, the caves aforementioned had a very low population density of Endecous infernalis n. sp. Hence, it was relatively hard to find specimens (especially adults) in all the caves in which it occurs. Although practically the entire ACCS has been inventoried for cave invertebrates in a study carried out in 2017 (Souza-Silva et al. 2021), only few specimens were found, mainly in deep and moistened areas within the system. It is noteworthy that the two caves located at the intermediate portion of the ACCS (Gruna dos Índios and Lapa dos Peixes caves) have a quite dry main conduit due to the airflow that comes from the entrances in both sides of their main conduits and trespasses both caves. Because of that, individuals of E. infernalis n. sp. were seldom observed in this intermediate portion of the ACCS, probably due to the unstable climatic conditions of the caves. A second population was observed in the Gruna do Pedro Cassiano I cave in deeper areas within the cave, far from the entrance. Most specimens found in both cave systems were observed freely walking on the cave floor or in the caves’ walls (Figs. 30 and 31). Finally, a third population was recently discovered in the Baix„o da Canoa cave. Again, specimens were only observed in deeper and moistened areas, and, as a result of the low-density population, the individuals were thinly dispersed. A single adult male was collected, despite the sampling efforts employed along the cave. It is important to mention the distance among the Gruna da Água Clara cave system (ACCS), Gruna do Pedro Cassiano I and Baix„o da Canoa cave. While ACCS and Gruna do Pedro Cassiano I cave comprise close systems (entrances located approximately 4 km in a straight line from each other), the Baix„o da Canoa cave is located far from the first two cave systems (22 km in a straight line). All these caves are associated with the main massif of the Serra do Ramalho mountain range, which comprises a large continuous carbonate outcrop that runs from southwest to northeast. Furthermore, the Baix„o da Canoa cave is located at a higher altitude, being associated with a hydrological recharge zone in the landscape, while the ACCS and the Gruna de Pedro Cassiano caves are located at lower altitudes, being associated with the base of the outcrops in hydrological discharge zone. Thus, it is plausible to assume the existence of subterranean connectivity between those systems. An interesting observation was made in a deeper area of the Gruna da Água Clara cave (Part of the ACCS) during an expedition in 2017: an adult male was stridulating while a juvenile female was interacting with its cerci (Fig. 30). Although it was not possible to observe in detail, it seemed that the female was touching the basal region of the male’s cerci, where modified setae (globose setae) can be found, with her mouthparts. In both Grylloidea and Blattodea, club-shaped and globose setae are hypothesized to act as gravity receptors (Nicklaus 1969; Bischof 1975; Horn 1985; Hartman et al. 1987), but, as pointed out by Desutter-Grandcolas (1998a), further neuroethological studies of these insects are necessary to confirm or refute this function. Given the observed behavior, one can hypothesize that such setae may also attract females for mating, functioning eventually as a nuptial gift. Although the SEM images of such setae usually show them flattened, they are, in their natural state, swollen, due to being filled with fluid. Considering that the observed female was immature (the ovipositor was still short and not sclerotized), this behavior could represent an advantage in the case of oligotrophic environments and low-density populations, in which the encounter among specimens may be more infrequent, especially in extensive cave systems such as the ACCS. Nevertheless, such hypotheses deserve further studies in order to confirm or refute it. It is important to mention the troglomorphic traits observed in this species, which will be discussed further on. When compared to other Endecous species (most of which are troglophilic), E. infernalis n. sp. presents reduced eyes and longer legs. Other Endecous species previously considered troglobitic, as E. peruassuensis and E. apterus, presents much less regressive morphological traits than those observed in the species herein described. Bearing in mind the species distribution within the caves it inhabits (always in deeper moist regions) and the quite severe external dry habitat surrounding the caves, it is plausible to assume it is, in fact, a troglobitic (cave-restricted) species. Although Gruna do Pedro Cassiano cave receives local visitors sporadically, such visitors do not reach the cave deepest regions, where the specimens occur. The Gruna da Água Clara cave system, on the other hand, is only visited by speleologists during technical/scientific expeditions, which seldom occur. Such activities apparently do not represent a threat for the species. The Baix„o da Canoa cave was only visited once by the researchers who sampled the cave, thus it is pristinely preserved. The external environment surrounding the caves, however, is severely altered (Fig. 28). Most of the original forests were replaced by pastures or other monocultures. The forests remain only in the top and border of the limestone outcrops, in randomly dispersed patches of vegetation or alongside intermittent drainages. Such impacts may reduce the organic input to the cave ecosystems and increase the silting in all those caves, thus altering several microhabitats of this species., Published as part of Carvalho, Pedro Henrique Mendes, Junta, Vitor Gabriel Pereira, Castro-Souza, Rodrigo Antônio & Ferreira, Rodrigo Lopes, 2023, Three new cricket species and a new subgenus of Endecous Saussure, 1878 (Grylloidea: Phalangopsidae) from caves in northeastern Brazil, pp. 1-39 in Zootaxa 5263 (1) on pages 4-14, DOI: 10.11646/zootaxa.5263.1.1, http://zenodo.org/record/7797711, {"references":["Souza-Silva, M., Cerqueira, R.

Phallic complexes vary slightly in degree of sclerotization; pseudepiphallic arms (Ps.arm) vary subtly in degree of inclination towards the center of the sclerite; pseudepiphallic dorsal branches (Ps.db) always bent abruptly towards the interior of the sclerite, but may not be perpendicular to the pseudepiphallic arms; pseudepiphallic inner bars (Ps. ib) may be more or less inclined to the anterior portion of the phallic complex; anterior margin of the ectophallic arch (Ect.arc) may be more or less curved; ectophallic apodeme (Ect.ap) may be more or less inclined towards the interior of the sclerite; endophallic sclerite posterior portion (End.sc.p) shape varies slightly, yet retains the trapezoidal outline. Variations in male right tegmen (Figs. 87 – 92). Stridulatory file with 87.10 ± 5.17 teeth (n° = 10, holotype and paratypes).

Mirror outline always triangular, with a trapezoidal apex; two complete, V-shaped crossveins (Figs. 87, 89 and 92), two incomplete veins (Fig. 88) one complete vein (Fig. 91) or one incomplete vein (Fig. 90); a third short, diagonal vein may be present (Fig. 88). Basal field outline conserved; 1A may branch out into several irregular and poorly marked veins (Fig. 88). Lateral field with two parallel longitudinal veins, which may be curved outwards. Ecological remarks. Specimens of Endecous zaum n. sp. were observed in the Serra Verde, Gruna do Enfurnado and Gruna do Zeferini caves. However, many other caves exist in the area (most of them not biologically studied), so it is likely that other populations of E. zaum n. sp. may be found in the future. Serra Verde cave (the type locality) has at least 1,730 meters of horizontal projection, but it is still under exploration, so it might be longer than currently known. Even though the cave has a relatively wide entrance (Fig. 94), there is a constriction in the main conduit around 20 meters from the entrance, which prevents the locals from accessing the cave interior. The conduit that follows this constriction is relatively dry. Nevertheless, there are signs that the runoff water penetrates the cave in rainy periods. Our team visited the cave during the dry season, hence, the substrates were predominantly dry near the entrance. Nonetheless, it is important to mention that galleries became progressively wetter as depth increased, the conduits at the final portion of the cave being drenched in water (Fig. 95). Specimens of E. zaum n. sp. were observed in the humid galleries, far from the entrance, being more frequent in deeper regions of the cave. Individuals were most often seen on the cave floor (Fig. 96). The predominant organic resources were bat guano (especially produced by vampire bats— Desmodus rotundus) and plant debris brought by the water. In previous expeditions, speleologists discovered that the inner conduits partially flood during the rainy season, thus indicating that the water table varies greatly throughout the year. For that reason, it is fair to assume that these crickets probably migrate during rainy seasons to regions closer to the entrance that are not flooded. As aforementioned, the constriction on the conduit close to the entrance of the cave hinders the access of locals to its interior, which in turn guarantees the preservation of the cave’s inner environment. The external landscape, however, is severely altered, especially close to the limestone outcrops, where only a few remnants of the original vegetation can be verified (Fig. 93). Pastures replaced most of the native forests and cattle were observed in the cave surroundings (Fig. 97), compacting the exposed soil, which is highly vulnerable to erosive processes. Additionally, since the cave entrance is located at the bottom of a valley, the external topography ends up contributing to the input of sediments to the cave during rainy periods. The soil denudation in the external landscape can, therefore, intensify erosive processes, increasing the sediment input to the cave, and, consequently, silting up important microhabitats. Accordingly, it is highly recommendable to protect the cave surroundings, especially through the reforestation of the immediate external landscape, to preserve the cave and the species that it harbors. The other two caves where specimens were found (Gruna do Enfurnado and Gruna do Zeferini caves) are quite distinct from each other and from Serra Verde cave, thus indicating the species is quite versatile in occupying different caves. Whilst Zeferini cave is mostly dry (there is only one pond on the cave), the Enfurnado cave is trespassed by a stream. The cave´s sizes are also very distinct: Zeferini cave has around 300 meters, while Enfurnado cave has more than 7.5 km in extension. As observed for the Serra Verde cave, the external surroundings of both the Zeferini and Enfurnado caves are also altered by human activities, especially farming (crops and pastures). more...

Copulatory papilla sclerotized and short, anterior portion membranous, with an almost rectangular contour in dorsal and ventral views; distal portion widened, chalice-like, V-shaped ventral end longer than the also V-shaped dorsal end in lateral and dorsal views (Fig. 63). Ecological remarks. Specimens of Endecous zin n. sp. were found in four caves located in the municipalities of Carinhanha and Serra do Ramalho, southwestern Bahia State, Brazil. The Gruna das Três Cobras cave was defined as the type locality. This cave has 5,620 meters of horizontal projection (Silva et al. 2019), presenting internal conduits and chambers of labyrinthic aspect (Fig. 64). The cave has many entrances, most of them located at the base of the limestone outcrop. The cave atmosphere is constantly influenced by the airflow coming from those entrances and, as a consequence, several conduits dry out during the dry season (Fig. 65). However, due to the cave extension, there are moistened inner chambers located far from the entrances that remain humid even during the dry season. Specimens of Endecous zin n. sp. were observed in several areas along the cave, but never close to the entrances. They were usually walking on the cave floor or walls (Fig. 66). It is important to mention that this cave is partially flooded during the rainy season. Hence, the habitat of this species seems to be seasonally altered, thus, the crickets likely need to migrate to distinct areas in each season. The main organic resources occurring in the cave are plant debris from the epigean vegetation, and bat guano, the latter being more common in deeper regions of the cave. Such guano piles certainly represent an important food resource for this species, along with other decaying material, considering its generalist detritivore nature. This cave receives no human visitors, with the exception of few speleologists who sporadically explore it. Consequently, the cave is relatively well preserved. Nonetheless, the external area is highly degraded, with drone images revealing the extension of the logging activity in the cave surroundings (Fig. 64). Most areas were converted to pastures or had the vegetation removed and burned, maybe for future expansion of the grazing areas. As previously mentioned, such practices influence the organic input to the cave environment directly and, at the same time, contribute to the silting of many conduits and chambers inside the cave. Because of that, several microhabitats that might be important to this new species (among others) may be being severely altered by the external deforestation. In that sense, urgent actions are needed in order to prevent further negative impacts in the cave surroundings. Endecous zin n. sp. was also observed in other three caves located not far from the Gruna das Três Cobras cave (Gruna do Google, Gruna Grande and Gruna da Serra Solta II caves). Such caves are considerably long (more than 1km of horizontal projection) and have intermittent drainages along their main conduit. The Gruna do Google and Gruna Grande caves were only visited by speleologists since its discovery, due to the difficulty in accessing their inner portions. Hence, its interior is quite preserved. The Gruna da Serra Solta II cave, on the other hand, is partially impacted, especially at the entrance area, where locals pump water from a cistern using a diesel engine. However, since the cave is quite long, most of its extension is devoid of visible impacts caused by humans. It is worth noting that there are many other caves in that area that were not sampled, so it is quite plausible to assume that E. zin n. sp. is more widely distributed in the region. Similar to the Gruna das Três Cobras cave surroundings, the external landscape of Gruna do Google, Gruna Grande and Gruna da Serra Solta II caves is also altered, due to replacement of the original vegetation by pastures and crops. In that sense, it is important to highlight that the region is under risk, especially considering agriculture expansion and the growing threats of limestone extraction, which may impact the entire Serra do Ramalho region, affecting several caves, including those previously described. more...

Lateral field with two longitudinal veins that may or may not converge, but are usually connected through secondary veins and rarely completely parallel and isolated from one another throughout their extension. Ecological remarks. Specimens of Endecous infernalis n. sp. were found in Baix„o da Canoa cave, located in the municipality of Coribe, and in other two cave systems: the Gruna da Água Clara cave system (ACCS) and Gruna do Pedro Cassiano I cave (Fig. 29), both located in the municipality of Carinhanha, southwestern Bahia state, Brazil. The Água Clara cave system represents a set of functionally interconnected caves of approximately 24 km of extension. It is composed of four limestone caves trespassed by an intermittent stream, active during the austral summer (October until March) (Souza-Silva et al. 2021). The Gruna do Pedro Cassiano I cave (Fig. 29), in turn, is a single 2.660-meter-long cave that does not belong to the ACCS, but it is located near that system (approximately 4 km in a straight line). The Baix„o da Canoa cave was only recently discovered, so it was not yet properly explored. It is safe to say, however, that the surveyed conduits have at least 1.5 km of extension. This cave has a single known entrance, which leads to a crawling conduit that connects to a wide main chamber, representing the main cave conduit, which has an intermittent drainage active during rainy periods. Differently from what is usually observed for most of the Endecous species occurring in Brazilian caves, the caves aforementioned had a very low population density of Endecous infernalis n. sp. Hence, it was relatively hard to find specimens (especially adults) in all the caves in which it occurs. Although practically the entire ACCS has been inventoried for cave invertebrates in a study carried out in 2017 (Souza-Silva et al. 2021), only few specimens were found, mainly in deep and moistened areas within the system. It is noteworthy that the two caves located at the intermediate portion of the ACCS (Gruna dos Índios and Lapa dos Peixes caves) have a quite dry main conduit due to the airflow that comes from the entrances in both sides of their main conduits and trespasses both caves. Because of that, individuals of E. infernalis n. sp. were seldom observed in this intermediate portion of the ACCS, probably due to the unstable climatic conditions of the caves. A second population was observed in the Gruna do Pedro Cassiano I cave in deeper areas within the cave, far from the entrance. Most specimens found in both cave systems were observed freely walking on the cave floor or in the caves’ walls (Figs. 30 and 31). Finally, a third population was recently discovered in the Baix„o da Canoa cave. Again, specimens were only observed in deeper and moistened areas, and, as a result of the low-density population, the individuals were thinly dispersed. A single adult male was collected, despite the sampling efforts employed along the cave. It is important to mention the distance among the Gruna da Água Clara cave system (ACCS), Gruna do Pedro Cassiano I and Baix„o da Canoa cave. While ACCS and Gruna do Pedro Cassiano I cave comprise close systems (entrances located approximately 4 km in a straight line from each other), the Baix„o da Canoa cave is located far from the first two cave systems (22 km in a straight line). All these caves are associated with the main massif of the Serra do Ramalho mountain range, which comprises a large continuous carbonate outcrop that runs from southwest to northeast. Furthermore, the Baix„o da Canoa cave is located at a higher altitude, being associated with a hydrological recharge zone in the landscape, while the ACCS and the Gruna de Pedro Cassiano caves are located at lower altitudes, being associated with the base of the outcrops in hydrological discharge zone. Thus, it is plausible to assume the existence of subterranean connectivity between those systems. An interesting observation was made in a deeper area of the Gruna da Água Clara cave (Part of the ACCS) during an expedition in 2017: an adult male was stridulating while a juvenile female was interacting with its cerci (Fig. 30). Although it was not possible to observe in detail, it seemed that the female was touching the basal region of the male’s cerci, where modified setae (globose setae) can be found, with her mouthparts. In both Grylloidea and Blattodea, club-shaped and globose setae are hypothesized to act as gravity receptors (Nicklaus 1969; Bischof 1975; Horn 1985; Hartman et al. 1987), but, as pointed out by Desutter-Grandcolas (1998a), further neuroethological studies of these insects are necessary to confirm or refute this function. Given the observed behavior, one can hypothesize that such setae may also attract females for mating, functioning eventually as a nuptial gift. Although the SEM images of such setae usually show them flattened, they are, in their natural state, swollen, due to being filled with fluid. Considering that the observed female was immature (the ovipositor was still short and not sclerotized), this behavior could represent an advantage in the case of oligotrophic environments and low-density populations, in which the encounter among specimens may be more infrequent, especially in extensive cave systems such as the ACCS. Nevertheless, such hypotheses deserve further studies in order to confirm or refute it. It is important to mention the troglomorphic traits observed in this species, which will be discussed further on. When compared to other Endecous species (most of which are troglophilic), E. infernalis n. sp. presents reduced eyes and longer legs. Other Endecous species previously considered troglobitic, as E. peruassuensis and E. apterus, presents much less regressive morphological traits than those observed in the species herein described. Bearing in mind the species distribution within the caves it inhabits (always in deeper moist regions) and the quite severe external dry habitat surrounding the caves, it is plausible to assume it is, in fact, a troglobitic (cave-restricted) species. Although Gruna do Pedro Cassiano cave receives local visitors sporadically, such visitors do not reach the cave deepest regions, where the specimens occur. The Gruna da Água Clara cave system, on the other hand, is only visited by speleologists during technical/scientific expeditions, which seldom occur. Such activities apparently do not represent a threat for the species. The Baix„o da Canoa cave was only visited once by the researchers who sampled the cave, thus it is pristinely preserved. The external environment surrounding the caves, however, is severely altered (Fig. 28). Most of the original forests were replaced by pastures or other monocultures. The forests remain only in the top and border of the limestone outcrops, in randomly dispersed patches of vegetation or alongside intermittent drainages. Such impacts may reduce the organic input to the cave ecosystems and increase the silting in all those caves, thus altering several microhabitats of this species. more...

Ecological remarks. Specimens of Endecous zaum n. sp. were observed in the Serra Verde, Gruna do Enfurnado and Gruna do Zeferini caves. However, many other caves exist in the area (most of them not biologically studied), so it is likely that other populations of E. zaum n. sp. may be found in the future. Serra Verde cave (the type locality) has at least 1,730 meters of horizontal projection, but it is still under exploration, so it might be longer than currently known. Even though the cave has a relatively wide entrance (Fig. 94), there is a constriction in the main conduit around 20 meters from the entrance, which prevents the locals from accessing the cave interior. The conduit that follows this constriction is relatively dry. Nevertheless, there are signs that the runoff water penetrates the cave in rainy periods. Our team visited the cave during the dry season, hence, the substrates were predominantly dry near the entrance. Nonetheless, it is important to mention that galleries became progressively wetter as depth increased, the conduits at the final portion of the cave being drenched in water (Fig. 95). Specimens of E. zaum n. sp. were observed in the humid galleries, far from the entrance, being more frequent in deeper regions of the cave. Individuals were most often seen on the cave floor (Fig. 96). The predominant organic resources were bat guano (especially produced by vampire bats— Desmodus rotundus) and plant debris brought by the water. In previous expeditions, speleologists discovered that the inner conduits partially flood during the rainy season, thus indicating that the water table varies greatly throughout the year. For that reason, it is fair to assume that these crickets probably migrate during rainy seasons to regions closer to the entrance that are not flooded. As aforementioned, the constriction on the conduit close to the entrance of the cave hinders the access of locals to its interior, which in turn guarantees the preservation of the cave’s inner environment. The external landscape, however, is severely altered, especially close to the limestone outcrops, where only a few remnants of the original vegetation can be verified (Fig. 93). Pastures replaced most of the native forests and cattle were observed in the cave surroundings (Fig. 97), compacting the exposed soil, which is highly vulnerable to erosive processes. Additionally, since the cave entrance is located at the bottom of a valley, the external topography ends up contributing to the input of sediments to the cave during rainy periods. The soil denudation in the external landscape can, therefore, intensify erosive processes, increasing the sediment input to the cave, and, consequently, silting up important microhabitats. Accordingly, it is highly recommendable to protect the cave surroundings, especially through the reforestation of the immediate external landscape, to preserve the cave and the species that it harbors. The other two caves where specimens were found (Gruna do Enfurnado and Gruna do Zeferini caves) are quite distinct from each other and from Serra Verde cave, thus indicating the species is quite versatile in occupying different caves. Whilst Zeferini cave is mostly dry (there is only one pond on the cave), the Enfurnado cave is trespassed by a stream. The cave´s sizes are also very distinct: Zeferini cave has around 300 meters, while Enfurnado cave has more than 7.5 km in extension. As observed for the Serra Verde cave, the external surroundings of both the Zeferini and Enfurnado caves are also altered by human activities, especially farming (crops and pastures)., Published as part of Carvalho, Pedro Henrique Mendes, Junta, Vitor Gabriel Pereira, Castro-Souza, Rodrigo Antônio & Ferreira, Rodrigo Lopes, 2023, Three new cricket species and a new subgenus of Endecous Saussure, 1878 (Grylloidea: Phalangopsidae) from caves in northeastern Brazil, pp. 1-39 in Zootaxa 5263 (1) on pages 23-32, DOI: 10.11646/zootaxa.5263.1.1, http://zenodo.org/record/7797711 more...

Ecological remarks. Specimens of Endecous zin n. sp. were found in four caves located in the municipalities of Carinhanha and Serra do Ramalho, southwestern Bahia State, Brazil. The Gruna das Três Cobras cave was defined as the type locality. This cave has 5,620 meters of horizontal projection (Silva et al. 2019), presenting internal conduits and chambers of labyrinthic aspect (Fig. 64). The cave has many entrances, most of them located at the base of the limestone outcrop. The cave atmosphere is constantly influenced by the airflow coming from those entrances and, as a consequence, several conduits dry out during the dry season (Fig. 65). However, due to the cave extension, there are moistened inner chambers located far from the entrances that remain humid even during the dry season. Specimens of Endecous zin n. sp. were observed in several areas along the cave, but never close to the entrances. They were usually walking on the cave floor or walls (Fig. 66). It is important to mention that this cave is partially flooded during the rainy season. Hence, the habitat of this species seems to be seasonally altered, thus, the crickets likely need to migrate to distinct areas in each season. The main organic resources occurring in the cave are plant debris from the epigean vegetation, and bat guano, the latter being more common in deeper regions of the cave. Such guano piles certainly represent an important food resource for this species, along with other decaying material, considering its generalist detritivore nature. This cave receives no human visitors, with the exception of few speleologists who sporadically explore it. Consequently, the cave is relatively well preserved. Nonetheless, the external area is highly degraded, with drone images revealing the extension of the logging activity in the cave surroundings (Fig. 64). Most areas were converted to pastures or had the vegetation removed and burned, maybe for future expansion of the grazing areas. As previously mentioned, such practices influence the organic input to the cave environment directly and, at the same time, contribute to the silting of many conduits and chambers inside the cave. Because of that, several microhabitats that might be important to this new species (among others) may be being severely altered by the external deforestation. In that sense, urgent actions are needed in order to prevent further negative impacts in the cave surroundings. Endecous zin n. sp. was also observed in other three caves located not far from the Gruna das Três Cobras cave (Gruna do Google, Gruna Grande and Gruna da Serra Solta II caves). Such caves are considerably long (more than 1km of horizontal projection) and have intermittent drainages along their main conduit. The Gruna do Google and Gruna Grande caves were only visited by speleologists since its discovery, due to the difficulty in accessing their inner portions. Hence, its interior is quite preserved. The Gruna da Serra Solta II cave, on the other hand, is partially impacted, especially at the entrance area, where locals pump water from a cistern using a diesel engine. However, since the cave is quite long, most of its extension is devoid of visible impacts caused by humans. It is worth noting that there are many other caves in that area that were not sampled, so it is quite plausible to assume that E. zin n. sp. is more widely distributed in the region. Similar to the Gruna das Três Cobras cave surroundings, the external landscape of Gruna do Google, Gruna Grande and Gruna da Serra Solta II caves is also altered, due to replacement of the original vegetation by pastures and crops. In that sense, it is important to highlight that the region is under risk, especially considering agriculture expansion and the growing threats of limestone extraction, which may impact the entire Serra do Ramalho region, affecting several caves, including those previously described., Published as part of Carvalho, Pedro Henrique Mendes, Junta, Vitor Gabriel Pereira, Castro-Souza, Rodrigo Antônio & Ferreira, Rodrigo Lopes, 2023, Three new cricket species and a new subgenus of Endecous Saussure, 1878 (Grylloidea: Phalangopsidae) from caves in northeastern Brazil, pp. 1-39 in Zootaxa 5263 (1) on pages 14-16, DOI: 10.11646/zootaxa.5263.1.1, http://zenodo.org/record/7797711, {"references":["Silva, R.

The current work presents the description of a new species for the genus Arachnopsita Desutter-Grandcolas & Hubbell, 1993 from caves in the municipality of Raxruhá, Alta Verapaz, Guatemala. The morphology of the phallic complex was used as the main criterion for distinguishing the species. In addition, we present the additional description for Arachnopsita cavicola (Saussure, 1897) and Arachnopsita uncinata Desutter-Grandcolas, 1997 from a new analyzed material. Finally, we present some ecological remarks for all the studied species as well as a brief discussion on troglomorphic traits for the genus. more...

The genus Erebonyx was proposed to accommodate a single troglobitic species from northeastern Brazil. A second cricket belonging to this genus is herein described, but although it was also found in caves, it does not bear any troglomorphic traits, suggesting it is a troglophilic species. The new species differs from the other species on the genus in the phallic sclerites, presence of developed eyes (with ommatidia), pigmented integument, and the presence of stridulatory file on the tegmina. In addition, we present the description of the external morphology, together with the staining and description of tegmina. Finally, we present a brief discussion regarding its habitat, distribution and possible conservation actions for the species. more...

Bambuina zikani Souza-Dias & Borille n. sp. Figs. 1–4 Etymology. Species named after Joseph Francisco Zikán (1881–1949), a Czech entomologist who greatly contributed to the knowledge of the Brazilian insect fauna in the first half of the last century. Zikán conducted expeditions to collect insects in several localities of the Atlantic Forest, mainly in the Parque Nacional do Itatiaia (Itatiaia National Park) area, where he worked as a naturalist for many years. During his lifetime, Zikán assembled large collections, mainly Lepidoptera, Coleoptera, and Hymenoptera, which are now housed at the Instituto Oswaldo Cruz (IOC) (Rio de Janeiro). Type locality. Brazil, Rio de Janeiro, Itatiaia. Type material. Holotype, allotype, and paratypes: 5 males and 4 females (MNRJ); 1 male and 1 female (MZSP).

The knowledge of bioacoustics of the Neotropical crickets (Orthoptera, Gryllidea) is incipient, despite the great species diversity in the region. There are few cricket song-files deposited in the major World Sound Libraries, compared to other groups such as birds and amphibians. In order to contribute to the knowledge of the bioacoustics of Brazilian crickets, we organize, analyze and make available at Fonoteca Neotropical Jacques Vielliard (FNJV) and Orthoptera Species File (OSF) our bank of cricket songs. We deposited 876 cricket’s song files in the FNJV, belonging to 31 species and 47 sonotypes. The songs were field/lab recorded, and all individuals were collected to improve species/sonotypes taxonomic determination accuracy. We present photos (in vivo) of most recorded crickets, as well as calling song spectrograms to facilitate the species/sonotype recognition. Samples of the songs can be found online on the FNJV website, using the codes available in this work, as well as on the OSF, linked to the species name. As a result, we advance the knowledge of the songs of crickets and the current perspective of the Brazilian cricket bioacoustics. We encourage researchers to share with the public their collections of their cricket file songs both in the FNJV and the OSF. more...

The Phalangopsidae crickets (Grylloidea) of the Seychelles are examined following extensive field sampling on several main islands of the archipelago (Mahé, Silhouette, Praslin, La Digue). Despite the small area of these islands, six genera (12 species) are documented, including one new genus and five new species. The type species of the genus Seychellesia Bolivar, 1912 is transferred to the genus Paragryllodes Karny, 1909 as Paragryllodes nitidula (Bolivar, 1912) n. comb. The other species described in Seychellesia are transferred to the genus Seselia Hugel & Desutter-Grandcolas, n. gen., as Seselia longicercata (Bolivar, 1912) n. comb. and Seselia patellifera (Bolivar, 1912) n. comb. Two new species are also described in the genus Seselia Hugel & Desutter-Grandcolas, n. gen., Seselia coccofessei Hugel & Desutter-Grandcolas, n. gen., n. sp. (type species of the genus) and Seselia matyoti Hugel & Desutter-Grandcolas, n. gen., n. sp. The genera Phaeogryllus Bolivar, 1912 and Phalangacris Bolivar, 1895 are redescribed, including Phalangacris ferlegro Hugel & Desutter-Grandcolas, n. sp. and Phalangacris sotsote Hugel & Desutter-Grandcolas, n. sp. that are new to science. The genus Gryllapterus Bolivar, 1912 is redescribed and transferred from the Landrevinae (Gryllidae) to the Cachoplistinae (Phalangopsidae). New tribes are defined for the genus Paragryllodes (Paragryllodini Hugel & Desutter-Grandcolas, n. tribe) on the one hand, and for Seselia Hugel & Desutter-Grandcolas, n. gen., Phalangacris, Phaeogryllus and Gryllapterus (Seselini Hugel & Desutter-Grandcolas, n. tribe) on the other, using morphological characters and the results of molecular phylogenetic studies (Warren et al. 2019). Phaloria (Papuloria) insularis (Bolivar, 1912) (Phaloriinae) is redescribed and restricted to Mahé, and its calling song is documented for the first time, while Phaloria (Papuloria) bolivari Hugel & Desutter-Grandcolas, n. sp. is newly described from Silhouette. Identification keys are proposed for the genera of Seselini Hugel & Desutter-Grandcolas, n. tribe, and for the species of Seselia Hugel & Desutter-Grandcolas, n. gen. and Phalangacris. The confusion between the Mogoplistidae Ornebius succineus Bolivar, 1912 and the Phalangopsidae Heterotrypus succineus Bolivar, 1910 is discussed, and the name Subtiloria succineus (Bolivar, 1912) considered a nomen nudum.; Les grillons Phalangopsidae (Grylloidea) des Seychelles sont étudiés sur la base d'un échantillonnage intensif sur plusieurs îles principales de l'archipel (Mahé, Silhouette, Praslin, La Digue). Malgré la petite taille de ces îles, six genres (12 espèces) sont documentés, dont un genre nouveau et cinq espèces nouvelles. L'espèce type du genre Seychellesia Bolivar, 1912 est transférée dans le genre Paragryllodes Karny, 1909 en tant que Paragryllodes nitidula (Bolivar, 1912) n. comb. Les autres espèces décrites dans Seychellesia sont transférées dans le genre Seselia Hugel & Desutter-Grandcolas, n. gen., en tant que Seselia longicercata (Bolivar, 1912) n. comb. et Seselia patellifera (Bolivar, 1912) n. comb. Le genre Seselia Hugel & Desutter-Grandcolas, n. gen. comprend d'autre part Seselia coccofessei Hugel & Desutter-Grandcolas, n. gen., n. sp. (espèce type du genre) et Seselia matyoti Hugel & Desutter-Grandcolas, n. gen., n. sp. Les genres Phaeogryllus Bolivar, 1912 et Phalangacris Bolivar, 1895 sont redécrits, Phalangacris ferlegro Hugel & Desutter-Grandcolas, n. sp.et Phalangacris sotsote Hugel & Desutter-Grandcolas, n. sp. sont nouveaux pour la science. Le genre Gryllapterus Bolivar, 1912 est redécrit et transféré des Landrevinae (Gryllidae) aux Cachoplistinae (Phalangopsidae). Des tribus nouvelles sont définies pour le genre Paragryllodes (Paragryllodini Hugel & Desutter-Grandcolas, n. tribu) d'une part, et pour Seselia Hugel & Desutter-Grandcolas, n. gen., Phalangacris, Phaeogryllus et Gryllapterus (Seselini Hugel & Desutter-Grandcolas, n. tribu) d'autre part, sur la base de la morphologie et des données de phylogénie moléculaire (Warren et al. 2019). Phaloria (Papuloria) insularis (Bolivar, 1912) (Phaloriinae) est finalement redécrite de Mahé, et son chant d'appel documenté pour la première fois, tandis que Phaloria (Papuloria) bolivari Hugel & Desutter-Grandcolas, n. sp. est nouvellement décrite de Silhouette. Des clés d'identification sont proposées pour les genres de Seselini Hugel & Desutter-Grandcolas, n. tribu, ainsi que pour les espèces de Seselia Hugel & Desutter-Grandcolas, n. gen. et Phalangacris. La confusion entre Ornebius succineus Bolivar, 1912 (Mogoplistidae) et Heterotrypus succineus Bolivar, 1910 (Phalangopsidae) est discutée, et le nom Subtiloria succineus (Bolivar, 1912) considéré comme un nomen nudum. more...

Tribe Aclodini Desutter-Grandcolas, 1992 Comments. This tribe was proposed by Desutter-Grandcolas (1992), initially as the group “Aclodae”, including Aclodes Hebard, 1928, Paraclodes Desutter-Grandcolas, 1992 and Uvaroviella Chopard, 1923. The author defines the group and suggests that two species of Heterogryllus Saussure, 1874, H. crassicornis Saussure, 1878, and H. bordoni Chopard, 1970, were located in Aclodes and Paraclodes, respectively. Desutter-Grandcolas (1992), mentions that Heterogryllus only includes H. ocellaris Saussure, 1874, represented by a female collected in Brazil, without precise locality, and that, due to its morphological characteristics, it should be included in Neoaclini (sensu Desutter 1987). Nischk & Otte (2000) described several taxa for Ecuador, one species for Paraclodes and three species for Aclodes. Otte (2006) describes five additional species from Costa Rica. Otte & Perez-Gelabert (2009) added 16 species to Uvaroviella, distributed on several Caribbean islands. Subsequently, several taxa described by the above authors will be reassigned to other genera or synonymized, and not all species will retain their original combinations. Gorochov (2007) proposed that the Aclodae group comprises a single genus. Uvaroviella, the oldest genus, retained generic status, the others as subgenera: four originally described as genera (Acla Hebard, 1928, Aclodes, Paraclodes, and Uvaroviella s.s.) and five as new subgenera (Subacla, Euacla, Reacla, Holacla, and Topacla). The same author adds six species in Uvaroviella s.l., and keeps this taxon in the tribe Phalangopsini; for Paragryllini, it gives a new status, including subtribes described as tribes by Desutter (Paragryllina s.s., Neoaclina and Strogulomorphina). This contribution initiated some synonymization of taxa described by Otte and other authors (Gorochov 2011). Gorochov (2014) proposed a classification for the Phalangopsinae subfamily group. Uvaroviella and Heterogryllus are included in the subtribe Heterogryllina (Phalangopsini), sugesting the probable relationship between both taxa, and indicating that Aclodae is probably junior synonym of Heterogryllina (Gorochov 2014, 2015). Desutter-Grandcolas (2014) officially proposed Acla, as a synonym of Aclodes, something that apparently was missing in the author’s contribution of 1992, where A. crassicornis (Saussure, 1878) is included in Aclodes, without any formal nomenclatural act. Recently, Desutter-Grandcolas & Faberon (2020) revalidated and elevated Aclodini (=Aclodae) to tribal status and provided the initial opinion on the position of Heterogryllus and the non-relationship with the other Aclodini (Desutter-Grandcolas 1992). Likewise, they contrast with the Chintauan-Marquier et al. (2016) molecular study and other unpublished studies, highlighting that the Aclodini are a well-defined monophyletic clade within the Paragryllinae, thus supporting the new tribal status (Desutter-Grandcolas 2014, Desutter-Grandcolas & Faberon 2020). Also, they morphologically redefine Aclodini, returning to the 1992 classification, assigning generic status to Aclodes and Paraclodes, and synonymizing all the subgenera proposed by Gorochov (2007). They emphasize the incomplete study of morphological characters and that monophyly was not reflected in Gorochov’s proposal (Desutter-Grandcolas & Faberon 2020). As noted in the history of the classification of the Aclodae / Aclodini / Heterogryllina, cricket taxonomy remains in constant debate and turmoil. At the Neotropical level, it is based on the classification proposed either by Desutter-Grandcolas or Gorochov. Based on the author a tribe can be a genus or subtribe, and according to the opinion of some other authors the taxa can be in different subfamilies (Cadena-Castañeda & Tíjaro 2020, Cadena-Castañeda & García García 2020, Cadena-Castañeda et al. 2021b)., Published as part of Cadena-Castañeda, Oscar J., Quintana-Arias, Ronald Fernando, Rodríguez, Diana Marcela Tru- Jillo, Sarmiento, Juan Pablo Prias & Castellanos-Morales, Cesar A., 2022, Studies on Neotropical crickets: Aclodes paz n. sp. a new phalangopsid cricket (Orthoptera: Phalangopsidae) from the Santander caves, Colombia, pp. 568-580 in Zootaxa 5141 (6) on page 570, DOI: 10.11646/zootaxa.5141.6.3, http://zenodo.org/record/6598032, {"references":["Hebard, M.

Castellanos-Morales leg. 1 male and 2 females (CAUD). Etymology. This species is named after the La Paz municipally (type locality). But we also want to dedicate the name of this species to the desire for peace of Colombians and many people from other countries, who have various conflicts in their territories. We keep “ paz ” as a specific epithet for the type locality, but it also means peace in Spanish, Italian and Portuguese, coming from the Latin “ Pax ”. Description. Male. Mid-sized (Figs. 1A,B). Body predominantly ochre brown with dark brown and yellow stripes. Head brown with almost yellowish and grey spots and stripes; antennal scape partly light, flagellum dark brown without light spots (Fig. 1C). Pronotum mostly brown, pronotal disc with few yellow-brown stripes (Fig. 2A), lateral lobes dark brown (Fig. 1D). Fore and middle femora and tibiae brown spotted, with rings, to the femora with one or two rings on the mid-distal section, to the tibiae with three rings, one on the base, the next on the middle, and the last at the apex. Hind femora ochre with numerous brownish oblique lines on the outer surface and several spots on inner surface and apex, tarsi almost ochre. Tegmina brown with several yellow short hairs (Fig. 1E). Abdomen and terminalia dark brown with diffuse ochre spots (Fig. 2D). Head rounded, almost as wide as high in frontal view (Fig. 1C); maxillary palpi mid-sized, third and fourth subequal and cylindrical, the fifth flattened, dilated from the middle to the apex, and distally truncated (Fig. 1D). Thorax. Pronotal disc rather short, wider than long, anterior margin slightly concave, posterior margin straight (Fig. 2A), lateral margins curved and most prominent at the anterior part and upcurved to the posterior margin (Fig. 1D). Meso- and metanotum without glands or modifications. Legs. Fore tibia with tympana small and ovoid, only on inner side, and armed at the apex with a small spur on each side; mid tibia armed with two mid-sized spurs at the apex on each side. Hind tibia with three inner spurs and four outer spurs dorsally, and between them with small spines; apex with three apical spurs on both sides, the mid spur of outer margin is longer than the others one; the mid and ventral spurs almost similar in length and longer than the dorsal one. First tarsomere of the hind leg, with one spine on inner side close to apex and four dorsal spines on outer side, apex armed with a spur on both sides, the inner spur longer than the outer one. Tegmina ovoid, reaching to the third abdominal tergite (Figs. 1E, 2A). Mirror subtriangular, wider than long, with reticulated veins; harp with four or five dividing veins; chordal with two main veins (Fig. 2B); lateral field with three to four veins; stridulation file with 135–148 teeth (Fig. 2C). Abdomen with a pair of tentorial depressions for each tergite (Fig. 2D). Epiproctus rectangular longer than wide with the apex almost straight (Fig. 2E). Subgenital plate rectangular, longer than wide, and distally with a mid-undulation. Male genitalia. Ps.s. with the distal edge wavy in dorsal view and with a notch in the center (Fig. 3A). Ps.a.l. cylindrical, slightly curving towards the dorsal margin and latero-laterally flattened, with a few hairs on its surface, more conspicuous at the apex (Figs. 3A,B). Ps.p. quadrangular, ventrally with a small hook-shaped extension; distal edge wavy and longer on the outer edge (Fig. 3B). Ec.f. elongated and sclerotic, thickening from the anterior to the posterior region, diverging distally and connecting with a rounded prolongation and abundant microstructures (Fig. 3B, C). En.s. connecting with the ec.f., and sclerosed (Fig. 3B). Ec.a. dorsoventrally flattened rod-shaped, connected anteriorly with endophalic cavity, and posteriorly with ps.p. (Figs. 3B, C). R. wide and sclerotic, internally concave (Fig. 3B). Female. Similar to the male in shape and size, ocher or yellowish regions with lighter shades than the male (Fig. 4), being more noticeable on the face (Fig. 5A). Tegmina reduced (Fig. 5B), located on each side and covering the mesonotum and the base of the metanotum (Figs. 5C, D). Tenth tergite unmodified with rounded posterior edge. Epiproctus rectangular, wider than long, with two semicircular scars dorsally (Fig. 5E). Subgenital plate subtriangular, with the apex truncated (Fig. 5F). Ovipositor almost as length to the posterior femur; apex in dorsal view flattened and with denticulations on outer edges of upper valves, lower valves protruding into middle of upper valves, and with rounded distal edge (Fig. 5G); in lateral view, the apex of the ovipositor is lanceolate in shape and gently widens towards the apex (Fig. 5H). Variations. The main variation noted is between the two sexes; females have lighter shades than males in the yellowish and ocher areas. Some males have four or five veins dividing the harp. Measurements (in mm.). male/female: LB: 22–25/20–27. Pr: 3.5–4/4–4.5. Teg: 6–7/1–1.5. HF: 15–18/15– 19. HT: 17–20/17–20. Ov: 12–15. Comparison. Aclodes paz n. sp. is related to some species included in the subgenus Euacla (sensu Gorochov, 2007). Regarding the genitalia, the closest species is Aclodes chamocoru Nischk & Otte, 2000, which differs from the new species. Its tegmina cover the abdomen, and the harp has nine; the mirror is subovoid, wider than long, and crossed with two veins. In contrast, A. paz n. sp. has four or five veins on the harp, the mirror is subtriangular and with reticulate veins. The Ps.al. of A. chamocoru, is conical, and Ps.p. without ventral accessory extension; En.s. is tubuliform, and Ec.f. it does not expand, and difference in the connection area of these two structures. Comments. The specimens of the type series are slightly variable in size, as has been observed for other species of the genus. But one of the males from the “Colombian Hole” is unusually small. This male has all diagnostic characteristics to be identified as A. paz n. sp., such as wing venation and genital structure. Measurements of this specimen were not included in the species measurement ranges previously provided and are included below. Measurements (in mm.). LB: 14. Pr: 3. Teg: 6. HF: 12. HT: 13. Ecological data from type cave. The cave La Cuchara —2 is situated around four kilometers east from the La Paz town, on the eastern side of the Colombian Andean Mountain range. An area of different sedimentary lithostratigraphic units from the Cretaceous age, which are gathered in the formations: Rosablanca, Paja, Tablazo, Simiti and Luna (Medoza-Parada et al. 2009). The La Cuchara cave has a circular-shaped entrance of around 1.5 meters with narrow, rocky, passageways, stalagmites, and stalactites few developed were observed. Inside the cave, there is a narrow stream with shallow pools forms. The bottom of each well is rocky and contains abundant fine sediment. The water temperature was 17.9°C, the cave temperature 18.1°C, and the water pH was 6.7. The fauna is scarce; there were a few colonies of bats (cf. Carollia sp.) inhabiting the cave ceiling. The base of the food chain is probably limited to crickets and their predators, spiders. Crickets usually occupy the middle and upper parts of rocky cave walls, where they form groups of varying sizes and different stages of development (Fig. 6). This cave has not as yet been registered in any recent speleological inventory of Santander (Castellanos-Morales & Moreno 2018, Dulcey-Ulloa & Lasso 2019)., Published as part of Cadena-Castañeda, Oscar J., Quintana-Arias, Ronald Fernando, Rodríguez, Diana Marcela Tru- Jillo, Sarmiento, Juan Pablo Prias & Castellanos-Morales, Cesar A., 2022, Studies on Neotropical crickets: Aclodes paz n. sp. a new phalangopsid cricket (Orthoptera: Phalangopsidae) from the Santander caves, Colombia, pp. 568-580 in Zootaxa 5141 (6) on pages 571-576, DOI: 10.11646/zootaxa.5141.6.3, http://zenodo.org/record/6598032, {"references":["Gorochov, A.

Genus Aclodes Hebard, 1928 Comments. This genus is very speciose, and currently includes 35 species, with a wide distribution from Costa Rica to Peru and northern South America, with a presence on a couple of islands near Venezuela (Cigliano et al. 2022). It differs from the morphologically similar genus Paraclodes, in that the males have the tegmina projecting from the middle of the abdomen onwards and with strong parallel longitudinal veins. The females are distinguished by their tegmina, often reaching the first abdominal tergite posterior margin (Desutter-Grandcolas 1992), except Aclodes cryptos (Nischk & Otte 2000), with the tegmina reaching the middle of the abdomen. Uvaroviella, is a Caribbean genus with 17 species that need to be re-studied. Possibly, the three continental species still included in Uvaroviella, which are only known from their females, should be included in the future in Aclodes, after finding the respective males that allow their generic affiliation to be identified. For Colombia, Hebard (1928) mentions the presence of Aclodes maculatum (Caudell 1918), described initially from Peru but with notable morphological differences. Hebard, at that time, did not study the internal genitalia; it was not a common practice of the time for the descriptions of Orthoptera. Perhaps with the study of the male genitalia it will be possible to resolve this problem, with the tegmina moderately developed, as occurs in many recently described species. Recently, Cadena-Castañeda et al. (2016) recorded the presence of Aclodes nebulosa (Gorochov, 2007) (then known as Uvaroviella (Holacla) nebulosa Gorochov, 2007), in the Rio Ñambi Nature Reserve, south of the department of Nariño. This is the only species with a reliable and confirmed record for Colombia. Now the second species of Aclodes for the country is described, coming from the caves of the Andes in northern Colombia., Published as part of Cadena-Castañeda, Oscar J., Quintana-Arias, Ronald Fernando, Rodríguez, Diana Marcela Tru- Jillo, Sarmiento, Juan Pablo Prias & Castellanos-Morales, Cesar A., 2022, Studies on Neotropical crickets: Aclodes paz n. sp. a new phalangopsid cricket (Orthoptera: Phalangopsidae) from the Santander caves, Colombia, pp. 568-580 in Zootaxa 5141 (6) on pages 570-571, DOI: 10.11646/zootaxa.5141.6.3, http://zenodo.org/record/6598032, {"references":["Hebard, M.

Adelosgryllus xambioa n. sp. (Figures 25–29, 30–37, 38–40, 41–42, 43–45, Table 1) Material examined. Holotype ♂, code ISLA 66153, Brazil, Tocantins state, Xambioá municipality, Explosão cave (6º 25’ 19.301” S; 48º 24’ 34.880” w), 22.ii.2018, Ferreira R.L. leg. Holotype condition: right tegmen and legs detached, and maintained in holotype tube. Distribution. Known only to Explosão cave (6º 25’ 19.301” S; 48º 24’ 34.880” W) municipality of Xambioá, Tocantins state, Brazil. Etymology. The specific epithet refers to the municipality of Xambioá, Tocantins state, where the species was found. Diagnosis. Combination of the following characteristics: superior inner base of paramere 1 more rounded (Ps.P1, Figs 26 and 28) (compared to A. lucifugus and A. ferratilis n. sp.), inner basal margin from paramere 1 with dilatation more pronounced (ventral, diagonal and front view) (Ps.P1.p, Figs 25, 28 and 29) (compared to A. lucifugus and A. ferratilis n. sp.); paramere 2 slightly dilated toward paramere 1 (dorsal view) (Ps.P2, Fig. 25); rami elongated and poorly sclerotized (R, Figs 25, 27 and 29); ectophallic fold poorly sclerotized, lateral border slightly towards outside (Ec.F, Fig. 26); endophallic sclerite underdeveloped (End.Sc, Fig. 26). Description, male holotype. Similar to A. ferratilis n. sp. with the following differences: body dark brown with head orange (in vivo) (Fig. 45) (body pale dark brown and head pale yellow after fixation in ethanol 70%) (Figs 30–37); compound eyes were depigmented due to ethanol fixation (comparation between figs 30 and 45, same individual); pronotum pale dark brown, poorly marked with a whitish vertical and without horizontal median band, two small symmetrical diagonal white spots near the distal portion (Fig. 32); Right tegmen: less sclerotized, covering the first five abdominal tergites (Fig. 33). Lateral field (in lateral view, Figs 33 and 42): diagonal vein (DV), subcostal (SC) and radial (R) with poorly marked irregular veins. Field (in ventral view, Fig. 41): harp with a median-longitudinal vein (L) more toward out, and four crossed veins (Hcv), the first forms a small cell, below curbital 2 (Cu2); mirror with a narrower proximal part of triangular shape, with two crossed veins (Mcv), unbranched; subgenital and supra-anal plates dark brown, shapes changed after fixation in ethanol (Figs 35–37); stridulatory file with 94 teeth. Observations in holotype phallic sclerites: Similar to A. ferratilis n. sp. with the following differences: phallic complex less sclerotized (Figs 25–29). Pseudepiphallic: superior inner base of paramere 1 more rounded (ventral view) (Ps.P1, Fig 26), inner basal margin from paramere 1 with a dilatation more pronounced (ventral, diagonal and front view) (Ps.P1.p, Figs 25, 28 and 29); paramere 2 slightly dilated toward paramere 1 (dorsal view) (Ps.P2, Fig. 25); rami poorly sclerotized (R, Figs 25, 27 and 29). Ectophallic invagination: posterior projections poorly sclerotized and quadrangular-shaped (similar to A. lucifugus) (Ec.Pr, Fig. 26); ectophallic fold poorly sclerotized, lateral border slightly towards outside (Ec.F, Fig. 26). Endophallus: endophallic sclerite underdeveloped (End.Sc, Fig. 26). Ecological Remarks The single observed specimen of Adelosgryllus xambioa n. sp. was found in the Explosão cave, which is a marble cave with 1203 meters of horizontal projection. A quarry that used to remove marble from the outcrop led to the collapse of the main cave entrance. Therefore, in order to access the cave, one should enter through a small opening located at the base of the outcrop, leading to a very narrow passage (Fig. 43). The floor along most part of the cave is covered with sediments (Fig. 44), although a few fallen blocks are also present. The organic resources in the cave are especially bat guano produced by several bat species although deposits produced by hematophagous bats are the most common. Additionally, vegetal debris transported by water during strong rains also occur in some areas. The cave is devoid of any regular water flow, but several areas can be partially flooded during the rainy period. The single collected specimen was observed freely walking on the cave floor (Fig. 45), close to a guano pile. It is important to mention that the cave was not entirely surveyed during our sampling, since a flashflood occurred forcing the team to quickly leave the cave. Accordingly, there is no information regarding the size of the species’ population and its density inside the cave. The region presents a climate Aw5 (according to the Köppen classification system), with an average annual precipitation of 1558 mm and an average annual temperature of 26.3ºC. The external area is altered, especially due to the removal of the natural vegetation and its replacement by Eucalyptus plantations. However, secondary forest surrounds the outcrop where the cave is located. As for the other species herein described, the epigean environments surrounding the cave were not sampled, so it is currently impossible to determine the habitat preference for this species. It is important to mention that despite the fact that the species was only found inside a cave, it does not exhibit any troglomorphic traits, thus not being a cave-restricted species. Since the external area was not sample, it is likely that the species’ distribution is much wider than currently known. more...

Ecological Remarks Specimens of Adelosgryllus ferratilis n. sp. were found in Curionópolis municipality, Pará state, Brazil. The caves where specimens were observed are located in an area regionally known as “Serra Leste”. This area presents several iron-ore caves, but also some quartzite caves. The species was observed in several caves in the area, especially those ferruginous. Such caves are usually small (few dozens of meters) and several cavities only comprises rock shelters, without aphotic areas. The main organic resources observed in those caves is the bat guano and vegetable organic debris, deposited by wind or water. Although the area was originally covered by a tropical rainforest (Amazon rainforest), it is currently highly impacted, by both the replacement of the forests by pastures and by mining activities. The populations of A. ferratilis n. sp. are usually small inside the caves, so that the species may use the caves only sporadically. However, since the external environments were not sampled, it is currently impossible to establish the actual distribution of this species (Figs 20–24). more...
