Item Expanding the range of the troglobitic millipede Pseudonannolene ambuatinga Iniesta & Ferreira, 2013: insights into its distribution and conservation status (Spirostreptida, Pseudonannolenidae)(2024-06-10) Iniesta, Luiz Felipe Moretti ; Oliveira, Marcus Paulo ; Brescovit, Antonio ; Bouzan, Rodrigo SalvadorPseudonannolene Silvestri, 1895 (Spirostreptida, Pseudonannolenidae) is one of the most common genera of millipedes in Brazilian caves. To date, only three troglobitic species are known in a list of 56 species described for the genus. In this study, we report new records of the cave-dwelling species Pseudonannolene ambuatinga Iniesta & Ferreira, 2013 in Minas Gerais state. These records extend its distribution by approximately 600 km2, making it the most widely distributed cave-dwelling millipede in the country. We also provide a new assessment of its conservation status based on the records and threats to its populations.Item Four new species of Drymusa Simon (Araneae, Drymusidae) from Brazilian Oriental Amazonia(Revista Brasileira de Zoologia, 2006-06) Bonaldo, Alexandre ; Rheims, Cristina ; Brescovit, AntonioItem A new cave spider of the genus Lygromma Simon (Araneae, Prodidomidae) From Minas Gerais, Brazil(Revista Ibérica de Aracnología, 2004) Rheims, Cristina ; Brescovit, AntonioItem 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 On the Neotropical spider Subfamily Masteriinae (Araneae, Dipluridae)(2018-08-30) Passanha, Victor ; Brescovit, AntonioThe Neotropical species of the diplurid subfamily Masteriinae are revised and redefined. Masteriinae now comprises four genera, Masteria L. Koch, 1893, Striamea Raven, 1981, a new genus, Siremata n. gen. and Edwa Raven, 2015, a fossil genus. The type species, Masteria hirsuta L. Koch, 1893, was used as basis for comparison and the knowledge of the genus has increased. Twelve species of Masteria are redescribed and eight new species are described: M. amarumayu n. sp.and M. mutumn. sp., from Brazil; M. yacambu n. sp.,from Venezuela; M. sabrinae n. sp.,from Martinique; M. tayrona n. sp.,from Colombia; M. aguaruna n. sp.,from Peru, M. soucouyant n. sp.,from Trinidad and Tobago; and M. galipoten. sp.,from the Dominican Republic. Females of Masteria aimeae (Alayón, 1995)and M. golovatchi Alayón, 1995are des-cribed for the first time. Females of M. spinosa (Petrunkevitch, 1925), M. petrunkevitchi (Chickering, 1964), M. lewisi (Chickering, 1964), M. barona (Chickering, 1966), M. downeyi (Chickering, 1966), M. simla (Chickering, 1966), M. co-lombiensis Raven, 1981 and M. pecki Gertsch, 1982 are illustrated for the first time and rediagnosed. Masteria tovarensis (Simon, 1889) and M. cyclops (Simon, 1889)are synonymized with M. lucifuga (Simon, 1889). Masteria modesta (Simon, 1892) is considered as species inquirendae and M. emboaba Pedroso, Baptista & Bertani, 2015 is considered as incertae sedis, as the type is lost. Both species of Striamea are revised and redescribed. A new genus, Siremata n. gen., is described and includes three Amazonian species: S. valteri n. sp., S. juruti n. sp., S. lucasaen. sp. Knowledge of the distribution ranges of the Neotropical Masteriinae are increased.Item A redescription of Isoctenus coxalis (F.O.P. Cambridge, 1902) comb. nov. and description of I. corymbus, a new species of cave dwelling spider (Araneae, Ctenidae, Cteninae) from the State of Goiás, Brazil(Revista Ibérica de Aracnologia, 2005) Polotow, Daniele; Brescovit, Antonio ; Franco, Flávia PellegattiItem Three new species of the genus Speocera (Araneae: Ochyroceratidae) from caves of the state of Minas Gerais, Brazil(2023-10-20) Brescovit, Antonio ; Zampaulo, Robson de Almeida ; Pedroso, Leandro; Cizauskas, IgorThree new species of the spider genus Speocera Berland, 1914 are described from caves of different lithologies, in the state of Minas Gerais, Brazil: Speocera canjica n. sp., S. pamonha n. sp. and S. vacaatolada n. sp., all based on males and females. Among the described species, S. vacaatolada n. sp., presents a palp morphology similar to that of Speocera pallida, where a reduction of bulb structures occurs.
