Item Coarazuphium lundi (Carabidae: Zuphiini), a new Brazilian troglobitic beetle, with the designation of a neotype for C. pains Álvares & Ferreira, 2002(2020-11) GIOVANNINI PELLEGRINI, THAIS; LOPES FERREIRA, RODRIGO; DE ALMEIDA ZAMPAULO, ROBSON; VIEIRA, LETÍCIAIn this paper, we describe Coarazuphium lundi sp. nov., from a single male specimen collected in Gruta 06L cave located in the municipality of Prudente de Morais (Minas Gerais state, Brazil). The two most striking differences between C. lundi and other species of the genus is the presence of two pairs of posterior supraorbital setae and the elytra shape with parallel, not rounded sides. Coarazuphium pains Álvares & Ferreira 2002 is an endemic species restricted to a few caves at the Bambuí Carbonatic Group in the midwest of Minas Gerais state, Brazil. The holotype of C. pains was unfortunately lost in 2010, due to a fire that destroyed almost the entire zoological collection at the Butantã Institute, São Paulo state in Brazil. In recent years, several species of the genus have been described and compared to C. pains only based on its paper description, clearly prompting the need for the C. pains neotype designation. In order to provide a necessary standard for comparison, a neotype is designed for this species based on the material collected from the best approximation of the type locality (caves). Lastly, we also provide a brief discussion on the presence of eyespots of C. cessaima, originally described as blind.- Cylindroniscus platoi (Isopoda: Oniscidea: Styloniscidae), a new cave-dwelling species from Lagoa Santa Karst, Southeastern Brazil(2018) FERNANDES, CAMILE SORBO; CAMPOS-FILHO, IVANKLIN SOARES; BICHUETTE, MARIA ELINAThe new species Cylindroniscus platoi n.sp. is herein described. As far as known, the species occurs only in three caves developed in a continuous limestone outcrop at Pedro Leopoldo municipality, Minas Gerais State. Cylindroniscus platoin. sp. is regarded as an endemic troglobite based on its limited distribution and on non-obvious troglomorphisms found on its body surface.

This is the first record of a cavernicolous kinnarid from the Old World, and the first record of a troglobitic fulgoromorphan hemipteran from mainland Spain, and also the 7th cavernicolous kinnarid species world-wide. Epigean Kinnaridae are not known from the present-day fauna of the Iberian Peninsula nor from Western Europe at large. The new species is regarded as a relict from an ancient fauna which is now ex-tinct. The new cavernicolous species could not be assigned to any of the existing genera, thus a new genus is established. Molecular data (COI barcode sequence) for the new species are presented. For the first time, a detailed description of the nymphal morphology of a kinnarid is provided. Information on its ecology, behaviour, distribution and conservation status is given, and biogeographic implications are discussed.
Item Four new species of the genus Ochyrocera (Araneae, Ochyroceratidae) from iron caves of the state of Minas Gerais, with the description of the third anophtalmic species from Brazil(2021-12-10) Brescovit, Antonio Domingos; Zampaulo, Robson de Almeida; Pedroso, Leandro Mota; Cizauskas, IgorFour new species of the spider genus Ochyrocera Fage, 1912 are described from iron caves in the state of Minas Gerais, Brazil. Here we present the third anophtalmic and depigmented species of the genus, O. dorinha sp. nov., and three other depigmented species: O. monica sp. nov., O. magali sp. nov. and O. rosinha sp. nov. Only O. dorinha sp. nov. and O. rosinha sp. nov. are considered as troglobites due the ocular reduction or anophthalmia and elongated appendages, two troglomorphic features absent in the other species described.Item Iandumoema uai, A New Genus And Species Of Troglobitic Harvestman From Brazil (Arachnida, Opiliones, Gonyleptidae)(Revista Brasileira de Zoologia, 1996) Rocha, Ricardo PintoItem Ituglanis boticario, a new troglomorphic catfish (Teleostei: Siluriformes:Trichomycteridae) from Mambaí karst area, central Brazil(Zoologia, 2014) Rizzato, Pedro Pereira; Bichuette, Maria ElinaItem A new genus of Micromygalinae (Araneae, Microstigmatidae) from Brazil, with transfer of Masteria emboaba Pedroso, Baptista & Bertani, 2015 and description of six new species(2019-01-08) Passanha, Victor; Cizauskas, Igor; Brescovit, AntonioThe family Microstigmatidae is composed of two subfamilies, Microstigmatinae and Micromygalinae, seven genera and 16 species. Micromygalinae is monotypic, comprising the species Micromygale diblemma Platnick & Forster, 1982 from Panama. A new genus, Tonton is described as a new member of the Micromygalinae. Masteria emboaba Pedroso, Baptista & Bertani, 2015, is transferred to the new genus and six new species from Brazil are described and attributed to Tonton gen. n.: the type species, T. itabirito sp. n., T. queca sp. n., T. matodentro sp. n. and T. sapalo sp. n., all from the state of Minas Gerais; T. ipiau sp. n. from the state of Bahia and T. quiteria sp. n. from the state of Maranhão. Among the cavernicolous species, only T. itabirito sp. n. is considered troglobitic by the total absence of eyes.Item New records of the troglobitic Hyalella veredae Cardoso & Bueno, 2014 (Crustacea, Amphipoda, Hyalellidae) from Minas Gerais caves, southeast Brazil, with notes on its natural history(2021-01-18) Elina Bichuette, Maria; A. P. Bueno, Alessandra; P. A. Resende, Leonardo; Zepon, TamiresSince its description, the troglobitic amphipod Hyalella veredae Cardoso & Bueno, 2014 has been recorded only in its type locality, Vereda da Palha cave, in southeastern Brazil. We report this species from three other caves in the region, expanding its distribution by at least 20 km². Inter- and intra-population variability in eye size was observed. Two caves had larger populations, probably due to the presence of biofilm. The species was classified as Critically Endangered due to its restricted area of occurrence, and regional impacts and threats.- New records of the troglobitic Hyalella veredae Cardoso & Bueno, 2014 (Crustacea, Amphipoda, Hyalellidae) from Minas Gerais caves, southeast Brazil, with notes on its natural history(2021-01-18) Zepon, Tamires; Resende, Leonardo; Bueno, Alessandra Angélica de Pádua ; Bichuette, Maria ElinaSince its description, the troglobitic amphipod Hyalella veredae Cardoso & Bueno, 2014 has been recorded only in its type locality, Vereda da Palha cave, in southeastern Brazil.

Item A New Remarkable Troglomorphic Gonyleptid From Brazil (Arachnida, Opiliones, Laniatores)(Revista Ibérica de Aracnologia, 2002) G, Abel Pérez; Kury, Adriano B.Item A new species of cave catfish from Brazil, Trichomycterus rubbioli sp.n., from Serra do Ramalho karstic area, São Francisco River basin, Bahia State (Silurifomes: Trichomycteridae)(2012) Rizzato, Pedro Pereira; Bichuette, Maria ElinaEstudo sobre uma nova espécie de bagre das cavernas do Brasil, Trichomycterus rubbioli sp.n., da área cárstica Serra do Ramalho, bacia do rio São Francisco, Estado da BahiaItem A new species of Chaimowiczia from the karstic Serra do Ramalho plateau, Brazil (Oniscidea, Synocheta, Styloniscidae)(2022-03-29) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Ferreira, Rodrigo LopesChaimowiczia belongs to the subfamily Iuiuniscinae, family Styloniscidae, and is currently composed of two troglobitic species: C. tatus and C. uai, both occurring in Brazil. A new species of Styloniscidae found in Brazil (Bahia state, Serra do Ramalho, Serra Verde cave) was allocated into this genus by the antenna flagellum with three articles; rectangular-shaped lateral pereonites epimera not apically acute and apex of pleopod 2 endopod with an acute tip and an acute or rounded lobe directed outwards. The new species, C. obybytyra sp. nov., is here described and rises to 25 the number of troglobitic styloniscidean species known for Brazilian caves.Item A new species of Spelunconiscus (Isopoda: Oniscidea: Styloniscidae) for Brazilian caves: new record for the type species and an emended diagnosis for the genus(2022) Bastos-Pereira, Rafaela; Souza, Leila Aparecida ; Sandi, Beatriz ; Ferreira, RodrigoSpelunconiscus Campos-Filho, Araujo and Taiti, 2014 is a monotypic genus of the family Styloniscidae represented by a troglobitic species, Spelunconiscus castroi Campos-Filho, Araujo and Taiti, 2014, from the cave MOC-32, in the state of Minas Gerais, southeastern Brazil. New representatives of this family were found in three additional caves, which revealed a new species, Spelunconiscus septemlacuum sp. nov., from Taboa and Tatuzinhos caves and a new occurrence for the type-species in Retiro cave. The original diagnosis of Spelunconiscus is emended due to the discovery of a spur-like structure in the male pereopod VII ischium, as well as some supplementary traits that have not been previously considered. Spelunconiscus septemlacuum sp. nov. differs from S. castroi in the number of articles of the antennal flagellum, in the proportion between this flagellum and 5th article of peduncle of antenna, in the size of maxilliped endite, in the morphology of male pleopod II and in body size. A discussion is provided for both taxonomic and ecological concerns.Item O primeiro registro de um Kinnaridae cavernicolous do Velho Mundo (Hemiptera, Auchenorrhyncha, Fulgoromorpha, Kinnaridae, Adolendini) fornece testemunhos de uma antiga fauna.(2021-01-11) Hoch, Hannelore; Sendra, Alberto; Montagud, Sergio; Teruel, Santiago; Ferreira, Rodrigo LopesA new obligately cavernicolous species in the planthopper family Kinnaridae is described from Spain.

In this sense, the present study aimed to evaluate the priorities for cave conservation through the combination of indexes that use species richness, species distribution, and proportion of the deforested area (PDA). The caves presented 287 non-troglobitic species and 37 species (11.7 %) with troglomorphic traits that are distributed in 50 % of the caves. The caves also present a high phylogenetic and functional diversity of terrestrial, aquatic, and amphibious cave-restricted species, including many predators, scavengers, and one phytophagous species, most of them presenting remarkable specialized traits and restrict distribution in a few caves and in specific biotopes. The PDA were positively related to the distance from the limestone outcrop, because of the restrictive landforms for agropastoral activities. At least two caves present extremely high priority for conservation (Baixão and Baixa da Fortuna caves), while four caves present high priority, and almost all others require at least a conservation action. Suggestively, in this specific case, a coherent strategy was shown to maintain the preserved vegetation around the caves, improving the restoration of small fragments and minimizing alterations. Despite the results of the indices, the singularity of the area regarding the taxonomic and functional diversity of troglobites also reinforces the urgent need for conservation actions.
