Remarks To date, the genus Alboscia comprises four species: A. elongata Schultz, 1995 from Paraguay; A. itaipuensis Araujo & Quadros, 2005, A. ornata Araujo, 1999 and A. silveirensis Araujo, 1999 from Brazil (Schultz 1995; Araujo 1999; Araujo & Quadros 2005). The genus is mainly defined by the slender habitus with lateral sides almost parallel, presence of conspicuous noduli laterales, epimera of pleonites closely appressed to pleon, maxillula outer endite with pectinate teeth on outer set and pleopod exopods without respiratory structures (Araujo 1999). The presence of pectinate teeth on the outer endite of the maxillula is present in other lineages of Oniscidea, e.g., Ligia Fabricius, 1798 (Ligiidae Leach, 1814), Armadilloniscus Uljanin, 1875 (Detonidae Budde-Lund, 1906)), Benthana Budde-Lund, 1904, Benthanops Barnard, 1932 and Ctenoscia Verhoeff, 1928 (Philosciidae), and Rhyscotidae Budde-Lund, 1908 (see Taiti & Ferrara 1982; Leistikow 1997; Schmidt 2002, 2003; Campos-Filho et al. 2015a). This character state is considered to be plesiomorphic (Leistikow 2001; Schmidt 2002). In the shape of the male pleopod 1 exopod, Alboscia jotajota sp. nov. resembles A. elongata and A. silveirensis. It differs from both species in having eyes with rudimentary ommatidia (vs three ommatidia in A. elongata; single ommatidium in A. silveirensis), antennula with six lateral aesthetascs arranged in three sets (vs five in one set in A. elongata; two in one set in A. silveirensis) and the male pleopod 1 endopod slightly longer than the exopod, with short and thickset distal portion (vs more than twice as long as exopod and distal portion slender in A. elongata; three times as long as exopod and distal portion slender in A. silveirensis). The absence of body pigment and absent/reduced eyes are common to all species of Alboscia, which probably indicates an endogean way of life. However, Alboscia jotajota sp. nov. is considered to be troglobiotic since no specimen was collected during surveys outside the caves where this species occurs.Published as part of Campos-Filho, Ivanklin Soares, Fernandes, Camile Sorbo, Cardoso, Giovanna Monticelli, Bichuette, Maria Elina, Aguiar, José Otávio & Taiti, Stefano, 2020, New species and new records of terrestrial isopods (Crustacea, Isopoda, Oniscidea) of the families Philosciidae and Scleropactidae from Brazilian caves, pp. 1-38 in European Journal of Taxonomy 606 on pages 6-11, DOI: 10.5852/ejt.2020.606, http://zenodo.org/record/367698

Senna-Horta and P.P. Rizzato. Remarks. To date, the genus Xangoniscus comprises three troglobiotic species with amphibious life-style, all endemic to Brazilian caves: Xangoniscus aganju, X. odara, and X. itacarambiensis. The genus is mainly defined by the complex wrench-like distal portion of the male pleopod 2 endopod, unique among the Styloniscidae (see Campos-Filho et al. 2014, 2016; Bastos-Pereira et al. 2017). The specimens from the two caves in the Bahia state here examined are tentatively identified as X. aganju since they show the same morphological characters. Only small differences are present in the apical lobes of the male pleopod 2 endopod (compare fig. 13C in Campos-Filho et al. (2014) with Fig. 7A, B, specimens from Caverna Chico Pernambuco, and Fig. 7C, specimens from Caverna Domingão). A molecular analysis of all the populations of X. aganju may clarify if these small differences indicate distinct taxa. The Chico Pernambuco and the Caverna Domingão caves are located in the Serra do Ramalho karst area, state of Bahia, northeastern Brazil. The caves are not legally protected and their surroundings are used for agriculture, pasture and projects for mining activities (Fig. 2A, B). The population of X. aganju from Chico Pernambuco is abundant in part of the drainage (level base stream) of the cave, reaching 8–10 inds/m 2 and showing gregarious habitus (Fig. 18B). The population from Caverna Domingão occurs in a phreatic habitat, a relatively large pool in the distal part of the cave with a high abundance, reaching 20 inds/m 2, preferring submersed organic matter (mainly trunks) and showing gregarious habits (Fig. 18C).Published as part of Campos-Filho, Ivanklin Soares, Fernandes, Camile Sorbo, Cardoso, Giovanna Monticelli, Bichuette, Maria Elina, Aguiar, José Otávio & Taiti, Stefano, 2019, Two new species and new records of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazilian caves, pp. 422-448 in Zootaxa 4564 (2) on pages 429-430, DOI: 10.11646/zootaxa.4564.2.6, http://zenodo.org/record/258928

Pleon narrower than pereon, pleonites 3–5 with epimera triangular, acute, and directed backwards (Fig. 11A). Telson (Fig. 11F) triangular, lateral sides straight and apex broadly rounded. Antennula (Fig. 11G) of three articles, distal article longest bearing seven lateral aesthetascs plus apical pair. Antenna (Fig. 11H) very long, reaching pereonite 4 when extended backwards, distal article of peduncle longer than flagellum; flagellum of three articles, proximal article longest, apical organ short bearing two long sensilla. Mandibles with molar penicil of eight branches and dense cushion of setae, left mandible (Fig. 12A) with 2+1 penicils, and right mandible (Fig. 12B) with 1+1 penicils. Maxillula (Fig. 12C) outer endite with two penicils, distal margin rounded; outer endite with 4+6 teeth, five of them pectinate, one short and simple. Maxilla (Fig. 12D) outer lobe twice as wide as inner lobe with distal margin sinuous, covered with thin setae; inner lobe rounded covered with thick setae.

Pleopod exopods with Benthana - type respiratory areas. Male. Pereopods 1–3 (Fig. 13B) merus and carpus with brushes of setae on sternal margin. Pereopod 7 (Fig. 13C) without sexual dimorphism. Genital papilla (Fig. 13D) with triangular ventral shield and two subapical orifices. Pleopod 1 (Fig. 13E) exopod heart-shaped, elongated (ratio z:y= 2.15), lateral protrusion prominent with acute apex, distal margin straight; endopod longer than exopod, stout and straight, distal portion with line of short setae. Pleopod 2 (Fig. 13F) exopod triangular, outer margin concave with two setae; endopod slender, distinctly longer than exopod. Pleopods 3 and 4 exopods as in Fig. 13G and H, respectively. Pleopod 5 exopod (Fig. 13I) triangular, outer margin almost straight with five setae. Remarks. The genus Benthana comprises 28 species mainly distributed in the Atlantic Forest areas of Brazil, with Benthana picta (Brandt, 1833) occurring also in Paraguay (Campos-Filho et al. 2015). Only two species were previously recorded from cave habitats, the troglobiont B. iporangensis Lima & Serejo, 1993 from Ressurgência das Areias de Água Quente and Areias de Cima caves (Areias system), and Gruta do Tatu cave, all included in conservation units in the state of São Paulo, and the non-troglomorphic and probably trogloxene B. taeniata Araujo & Buckup, 1994 from Gruta Zeferino I, state of Minas Gerais (Campos-Filho et al. 2014, 2015). Those caves are located in Chapada Diamantina region at the boundaires of Caatinga vegetation and surrounded by remains of the Atlantic forest and “campos rupestres” vegetation, a variation of Cerrado, not as dry as Caatinga (Fig. 2C, D). The new species occurs in very humid sandy (unconsolidated) or rocky substrate with organic matter (mainly moss close to creeks inside caves), showing medium abundance and densities (lower <0.5 inds/m 2) (Fig. 18D). The new species is considered to be troglobiotic. Benthana xiquinhoi sp. n. is similar to B. picta in the shape of the male pleopod 1 exopod; it is readily distinct in the reduced number of ommatidia, 10–12 (vs. 24 in B. picta), telson with distal margin rounded (vs. triangular), mandibles with eight branches on molar penicil (vs. 12), uropod exopod longer than endopod (vs. subequal), male pleopod 1 endopod straight (vs. bent outward s). Only Benthana schubarti Lemos de Castro, 1958 and B. iporangensis show eyes with reduced number of ommatidia, 16 and 18, respectively; Benthana xiquinhoi sp. n. distinctly differs from those species in the shape of the male pleopod 1 exopod (see Campos-Filho et al. 2015).Published as part of Campos-Filho, Ivanklin Soares, Fernandes, Camile Sorbo, Cardoso, Giovanna Monticelli, Bichuette, Maria Elina, Aguiar, José Otávio & Taiti, Stefano, 2019, Two new species and new records of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazilian caves, pp. 422-448 in Zootaxa 4564 (2) on pages 434-438, DOI: 10.11646/zootaxa.4564.2.6, http://zenodo.org/record/258928
