Item Checklist and identification key to Brazilian species of Triplocania Roesler (Psocodea: ‘Psocoptera’: Psocomorpha: Ptiloneuridae), with four new cave-dwelling species(2021-03-03) SILVA-NETO, ALBERTO MOREIRA; ALDRETE, ALFONSO N. GARCÍA; RAFAEL, JOSÉ ALBERTINO; FERREIRA, RODRIGO LOPESFour species of Triplocania are described and illustrated (T. brancoi n. sp., T. ferratilis n. sp., T. pains n. sp., and T. zairae n. sp.), all based on male specimens collected in caves of the Brazilian state of Minas Gerais. An identification key is presented to the Brazilian species of Triplocania, based on males, together with information on both sexes and distributions.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. 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 worldwide. 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 extinct. 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 Uma nova espécie troglobiótica de Allochthonius (subgênero Urochthonius) (Pseudoscorpiones, Pseudotyrannochthoniidae) do Japão(2021-01-20) Viana, Ana Clara Moreira; Ferreira, Rodrigo LopesAllochthonius (Urochthonius) yoshizawai sp. nov., found in Hiura-do Cave, a limestone cave located in the municipality of Kumakogen, Ehime Prefecture, Japan, is described. It can be distinguished from the consubgeneric species mainly by the carapacal chaetotaxy (6–2, 18), by the presence of 6 setae on the cheliceral palm, by the rallum with 11 blades, by the presence of 8 clavate coxal blades on coxae I, and by the decreased number and distinct shape of the chelal teeth. A redescription of the subgenus Urochthonius, and keys to the subgenera of Allochthonius and to the species and subspecies of Urochthonius are also provided, as well as some ecological remarks, a brief discussion on troglomorphisms for the subgenus, and potential threats for this species.Item The first record of Adelosgryllus Mesa & Zefa, 2004 (Orthoptera: Grylloidea: Phalangopsidae) from caves, with the description of a new species from Brazil(2004) MERLO, RAYANNE LAYS SANT’ANA; CASTRO-SOUZA, RODRIGO ANTÔNIO; JUNTA, VITOR GABRIEL PEREIRA; FERREIRA, RODRIGO LOPESThe first species for the genus Adelosgryllus Mesa & Zefa, 2004 recorded in caves is herein described. We used the morphology of the phallic complex as the main criteria to differentiate this species from the congeneric ones. In addition, we discussed the natural history of the new species, some aspects of its association to the cave habitats, and the intraspecific variation of the right tegmen observed in two populations of this new species.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 The first two blind troglobitic spiders of the genus Ochyrocera from caves in Floresta Nacional de Carajás, state of Pará, Brazil (Araneae, Ochyroceratidae)(2021-04-15) D. Brescovit, Antonio; de A. Zampaulo, Robson; Cizauskas, IgorThe first two anophthalmic species of spiders of the genus Ochyrocera Simon, 1892, are described for caves located in the iron formation of Floresta Nacional (FLONA) de Carajás in southeastern Pará State, Brazil. The caves are located in the municipalities of Parauapebas and Canaã dos Carajás, in the eastern portion of the Amazon Forest domain. Ochyrocera ritxocosp. nov. and O. ritxoosp. nov. are described based on males and females. The species have similar body characteristics with the total absence of eyes and complete depigmentation, characteristics that indicate possible evolution in subterranean environments , and thus are classified as troglobites. Each species is associated with a single geomorphological unit (mountain range), with Ochyrocera ritxocosp. nov. being restricted to caves of Serra Norte (North Mountain) and O. ritxoosp. nov. to caves of Serra Sul (South Mountain). Both species were collected in aphotic zones of the caves. Small and tangled webs of O. ritxocosp. nov. were observed under blocks of stone in the soil or in cracks of the walls.- Checklist and identification key to Brazilian species of Triplocania Roesler (Psocodea: ‘Psocoptera’: Psocomorpha: Ptiloneuridae), with four new cave-dwelling species(2021-03-03) MOREIRA DA SILVA NETO, ALBERTO; N. GARCÍA ALDRETE, ALFONSO; ALBERTINO RAFAEL, JOSÉ; LOPES FERREIRA, RODRIGOFour species of Triplocania are described and illustrated (T. brancoi n. sp., T. ferratilis n. sp., T. pains n. sp., and T. zairae n. sp.), all based on male specimens collected in caves of the Brazilian state of Minas Gerais. An identification key is presented to the Brazilian species of Triplocania, based on males, together with information on both sexes and distributions.

- Five new species of Phalangopsis Serville, 1831 (Orthoptera: Phalangopsidae) from Brazilian caves in the Amazon Forest(2020-10-06) PEREIRA JUNTA, VITOR GABRIEL; CASTRO-SOUZA, RODRIGO ANTÔNIO; LOPES FERREIRA, RODRIGOThe current work presents the description of five new cricket species for the genus Phalangopsis Serville, 1831 found in Brazilian caves in the Amazonas, Mato Grosso and Pará states, northern Brazil. The morphology of the phallic complex was used as the main criterion for distinguishing the species. In addition, we present data on the natural history and ecology of the new species as well as hypothesis about the variations of tegmina size in relation to the subterranean lifestyle for the genus. Finally, we provide a pictorial key based on adult males for the Phalangopsis species.
