1. New generic assignment to the harvestman Metaphareus punctatus (Opiliones: Stygnidae) and observations about it reproductive behavior
ABSTRACT We herein propose the transfer of Metaphareus punctatus Roewer, 1913, to the genus Eutimesius Roewer, 1913 (Heterostygninae) based on the genital morphology of the species and morphology of tarsi III and IV, resulting in the new combination Eutimesius punctatus (Roewer, 1913), comb. nov. New geographical records for E. albicinctus (Roewer, 1915) ar

2. More on the Mesopotamian-Yungas disjunction in subtropical and temperate Argentina: Bioclimatic distribution models of the harvestman Discocyrtus dilatatus (Opiliones: Gonyleptidae)
ABSTRACT In this paper, the potential distribution of the Mesopotamian harvestman Discocyrtus dilatatus Sørensen, 1884 is modeled, and the species' bioclimatic profile is described. Models were built with the presence-only methods Maxent and Bioclim, using 85 unique records (of which 49 are new) and 11 non-correlated bioclimatic variables as predictors. Bot

3. Four new species of Cosmetus from Panama, with comments on the systematics of the genus (Opiliones: Cosmetidae)
ABSTRACT Four new sympatric species of Cosmetus Perty, 1833 are described from "Reserva Natural Privada Burbayar, Provinciar Panamá, Panamá" (male holotypes deposited in MIUP). Cosmetus balboa sp. nov. can be distinguished by the combinations of following features: smooth ocularium, larger distal tubercle on pedipalpal femur, coxa I with large ventral tube

4. Forrageamento, sítios de oviposição e notas sobre a história natural do opilião Heteromitobates discolor (Opiliones, Gonyleptidae)
A falta de dados de história natural por vezes dificulta estudos filogenéticos sobre a evolução do comportamento. Nesse estudo nós fornecemos dados quantitativos de campo sobre forrageamento e sítios de oviposição de um opilião Neotropical pertencente a uma subfamília com uma filogenia publicada, Goniosomatinae. Heteromitobates discolor passa o dia

5. Revisão taxonômica do gênero Neotropical Neopachylus (Arachnida, Opiliones, Gonyleptidae)
Uma revisão taxonômica de Neopachylus Roewer 1913, juntamente com chaves para determinação de espécies com base em machos e fêmeas, são apresentadas. Duas espécies, ambas descritas por fêmeas, foram sinonimizadas: Gephyropachylus marginatus Mello-Leitão, 1931, considerado como sinônimo-júnior de Neopachylus serrinha Soares & Soares, 1947; e Hural

6. Viver no mesmo ambiente significa comer o mesmo alimento? Dieta e nicho trófico dos anuros simpátricos de folhiço Ischnocnema henselii e Adenomera marmorata em uma floresta do sul do Brasil
Neste estudo analisamos a composição da dieta e a amplitude e sobreposição do nicho trófico dos anuros de folhiço Ischnocnema henselii e Adenomera marmorata. Os anuros foram coletados em uma área de Mata Atlântica na Reserva Natural Salto Morato, no Estado do Paraná, Sul do Brasil, utilizando o método de parcelas de 16 m2 estabelecidas no chão da

7. A new species of Avima, the first record of Agoristenidae (Opiliones: Laniatores) from the state of Roraima, Brazil
We describe Avima anitas sp. nov. based on material collected in the Brazilian state of Roraima, representing the first record of Agoristenidae in the State. The new species differs externally from other species of Avima by presenting one proximal tubercle on the mesal face of the male cheliceral segment II and a pair of dark spots partially covering mesoter

8. Taxonomic revision of Parampheres (Arachnida: Opiliones: Gonyleptidae)
Parampheres Roewer, 1913 is a relatively common genus of South American harvestmen. This genus is easily diagnosed by the remarkable yellow patches on the prosoma. Nonetheless, species determination within this group is challenging due the convoluted taxonomic history of the group and lack of a recent revision. In this study we revise Parampheres and describ

9. A new species of Serracutisoma (Opiliones: Gonyleptidae: Goniosomatinae) from the coastal Atlantic Rain Forest of Paraná and São Paulo states, Brazil
Serracutisoma gnaspinii sp. nov. is described from the coastal Ombrophylous Dense Atlantic Rain Forest of Paraná and São Paulo states. It differs from other Serracutisoma by having a retrolateral row of spines on femur IV, a rounded white-mark on the carapace and a low dorsal apophysis on trochanter IV. It is likely the sister-species of S. proximum, and w

10. The first species of Roquettea from Maranhão, Brazil (Opiliones: Cosmetidae: Discosomaticinae)
Roquettea decioi sp. nov. is described from Carolina, in the Brazilian state of Maranhão. It is the seventh species in Roquettea Mello-Leitão, 1931 and the eighth species of Opiliones recorded from the state. Roquettea decioi sp. nov may be characterized by ocularium low, with median depression, pedipalpal tibia without pseudo-finger forming chela and mass

11. Paecilaema batman, a new species of Brazilian troglophilous harvestman that exhibits a remarkable color patches variation (Opiliones: Cosmetidae)
A new species of harvestman, Paecilaema batman, from Brazilian limestone caves of the state of Goiás, is described, and a remarkable intraspecific color patch variation is discussed. Paecilaema batman sp. nov. differs from other species of the genus by the following combination of features: chelicera similar in both sexes; prosoma without color patches; typ

12. A new species of Imeri (Opiliones: Stygnidae: Heterostygninae) from the Brazilian Amazon
A new species of Stygnidae Simon, 1879, Imeri ajuba sp. nov., is described based on males and females from Coari, Amazonas, Brazil. The new species, differs from the only other species of the genus, Imerilomanhungae Pinto-da-Rocha & Tourinho, 2012, in having the following characteristics: three white marks on posterior margin of dorsal scutum, one white mark
