76388792FFD30D79FF1E4101FC46FEAE.taxon	etymology	Etymology. From the latin: alba = white. The name refers to the lack of pigmentation in the new species. Morphological remarks. Benthana alba n. sp. presents some troglomorphic traits such as the lack of pigmentation and the reduction in the number of ommatidia. Benthana alba n. sp. is similar to B. iporangensis in the lack of pigmentation, in the shape of male pleopod 1 exopod, but it differs by the number of ommatidia (7 vs. 18 in B. iporangensis); by the number of aesthetascs on the antennula (19 + 2 vs. 11 + 2); and the articles proportion on the antenna (distal article longest vs. first article longest). Ecological remarks. Specimens of Benthana alba n. sp. were only found in the N 5 SM 2 _ 0077 cave (also known as cave GEM- 1762), in the plateau N 5 (Serra Norte complex) (Fig. 1). This cave comprises a small cavity with 13,5 meters of horizontal projection. It is inserted on the “ canga ” formation (a topmost ferruginous breccia) with its entrance located inside the forest. The external area surrounding the cave features large trees and sparse understory, in addition to abundant undergrowth. The cave is, in general, a shelter under a high external environmental influence and without completely aphotic zones. The entrance is wide (around 3.5 x 8 m) and presents a large amount of organic matter; the floor (composed of many collapsed blocks) descends through the internal wings after an abrupt drop. Inside the cave, the floor is predominantly flat and composed of granulated sediment with some pebbles and sparse boulders, and a small pile of hematophagous bat guano was observed. In the iron-ore outcrop where the N 5 SM 2 _ 0077 cave is located there are several other caves that were also sampled (at least twice, in both dry and rainy periods) but specimens of B. alba n. sp. were only recorded in this cave. However, in the ferruginous subterranean systems this fact does not mean that it is restricted or rare, since many invertebrate species associated with the ferruginous subterranean systems use the interstitial voids such as the canaliculi network (Ferreira et al. 2018) (Fig. 2 E). Therefore, specimens of Benthana alba n. sp. may be randomly found in macrocaverns, and this is at least partially reinforced by the small size of this cave (and consequently low environmental stability) where the specimens were found. On the other hand, one could think that the species is not restricted to subterranean habitats; however, external surveys for soil invertebrates accomplished in the Carajás region never revealed this species, thus indicating it should be considered as troglobitic. It is worth mentioning that the canaliculi network is usually very superficial, what causes such habitats to become highly vulnerable to the mining processes that advance over the region. Therefore, even considering the lack of information about the real distribution and population density of this species, it is plausible to consider it as highly threatened due to its specific habitat, and effective loss of habitat caused by activities related to the iron ore exploitation on its occurrence area.	en	Cardoso, Giovanna Monticelli, Ferreira, Rodrigo Lopes (2023): New troglobitic species of Benthana Budde-Lund, 1908 and Benthanoides Lemos de Castro, 1958 from iron-ore caves and their important record in the Amazon biome (Crustacea: Isopoda: Philosciidae).

76388792FFD40D74FF1E439DFC50FE42.taxon	etymology	Etymology. The name of the species refers to the locality of collection of the species, Amazon rainforest. Morphological remarks. Considering the absence of the autapomorphic state of the male pleopod 1 exopod with a lateral dentiform protrusion of Benthana (Leistikow 2001), this new species was placed in Benthanoides, a close related taxon which lacks this protrusion. Unfortunately, the descriptions of Benthanoides species lack important taxonomic information regarding the position of noduli laterales, the number and disposition of aesthetascs on antennula, and the shape of male pleopods (Jackson 1926, Van Name 1936, Gruner 1955). However, Benthanoides amazonicus n. sp. presents the shape of male pleopod 1 exopod similar to the pattern for the genus, without a dentiform protrusion. Ecological remarks. Specimens of Benthanoides amazonicus n. sp. were found in 25 caves in the N 1 plateau (Serra Norte complex). Since the specimens were collected by consulting company, unfortunately, no data were provided about the caves or the surrounding region. However, two aspects deserve to be highlighted: the first is the presence of large iron ore quarries in the N 1 region, which certainly represents a great risk for this species, especially concerning habitat loss and potential disconnection between populations (or sub-populations) that can become isolated and thus even more threatened. The second refers to the very small size of the specimens (about 4 mm), which demonstrates the access of these organisms to the canga’s canaliculi. Accordingly, such canaliculi may not only allow the dispersion of individuals between caves but also eventually comprise a significant portion of their habitat. In this perspective, the existing quarries in the region (in full expansion) certainly have the potential to fragment the populations of this species, increasing its risks of extinction.	en	Cardoso, Giovanna Monticelli, Ferreira, Rodrigo Lopes (2023): New troglobitic species of Benthana Budde-Lund, 1908 and Benthanoides Lemos de Castro, 1958 from iron-ore caves and their important record in the Amazon biome (Crustacea: Isopoda: Philosciidae).

76388792FFD80D70FF1E4317FF62FA2E.taxon	etymology	Etymology. The epithet name refers to the location where the species was found, Serra do Tarzan. Morphological remarks. Benthanoides tarzan n. sp. is similar to Benthanoides amazonicus n. sp. in the disposition of the aesthetascs on antennula, in the modifications on merus on pereopod 7, in the shape of male 1 endopod, and in the shape of male pleopod 2. They can be distinguished from each other by the shape of male pleopod 1 exopod, that is as wide as long in Benthanoides tarzan n. sp., and longer than wide in Benthanoides amazonicus n. sp. Ecological remarks. Specimens of Benthanoides tarzan n. sp. were observed in some caves located in “ Serra do Tarzan ” (ST). This area presents 69 caves, distributed along the whole extension of the ferruginous outcrop. Individuals of Benthanoides tarzan n. sp. were found in 10 caves (Fig. 1), thus indicating the species is widely distributed along the outcrop. Differently from Benthana alba n. sp., which may eventually inhabit voids in the ferruginous outcrop, the distribution of Benthanoides tarzan n. sp. indicates that this species seems to be also closely related to the macrocave itself. However, as the caves in which the species was observed are widely distributed throughout the iron ore formation, along with the specimens’ small body size, it is plausible to assume that migrations between caves through the canaliculi network occur. Furthermore, Be. tarzan n. sp. has a lower number of ommatidia among all known species of Benthanoides, and may indicate an important troglomorphic trait, and that the species is troglobitic. However, unlike B. alba n. sp., which seems to be highly threatened, Be. tarzan n. sp. occurs in a region inserted within the limit of a conservation unit (Campos Ferruginosos National Park), which fully protects the caves and their surrounding area, preventing touristic and exploratory activities; in addition, the geographic isolation protects the area in its pristine state. Therefore, this species seems not to be currently under any threat.	en	Cardoso, Giovanna Monticelli, Ferreira, Rodrigo Lopes (2023): New troglobitic species of Benthana Budde-Lund, 1908 and Benthanoides Lemos de Castro, 1958 from iron-ore caves and their important record in the Amazon biome (Crustacea: Isopoda: Philosciidae).
