Notes on Mitobatinae III: a remarkable new Brazilian species of Mitobates Sund., 1833 (Opiliones, Laniatores, Gonyleptidae)

Mitobates inermis n. sp. is described from Rio de Janeiro state (Southeastern Brazil). Unlike most mitobatines the individuals of this species lack the paired spines in the area III of the mesotergum. Owing to this character, the species, following the Roewerian system, should be put in a new genus, nearest to Léptocnema C.L . Koch,1839, but in the phylogenetic approach adopted here it is placed nearest to Mitobates conspersus (Perty, 1833).Mitobates inermis sp. n. é descrita do Estado do Rio de Janeiro (sudeste do Brasil). Ao contrário de quase todos os mitobatineos, os indivíduos desta espécie não possuem um par de espinhos na área III do mesotergo. Pelo sistema Roeweriano a espécie devido a esse caráter seria colocada em um novo gênero, prõximo a Leptocnema C.L . Koch, 1839, mas segundo um enfoque filogenético sugere-se aqui seu posicionamento junto a Mitobates conspersus (Perty, 1833)

A new species of discocyrtoides (Opiliones: Gonyleptidae: Bourguyinae)

A new species of Discocyrtoides Mello-Leitao, from the southern part of the state of Espirito Santo (southeastern Brazil), Discocyrtoides pardus sp. n., is described. Discocyrtoides maculatus H. Soares is newly recorded from the same state (central part). Some brief comments are made on the systematic position of the Bourguyinae and their relationships with the Mitobatinae.Indisponível

World Checklist of Opiliones species (Arachnida). Part 2: Laniatores – Samooidea, Zalmoxoidea and Grassatores incertae sedis

Including more than 6500 species, Opiliones is the third most diverse order of Arachnida, after the megadiverse Acari and Araneae. This database is part 2 of 12 of a project containing an intended worldwide checklist of species and subspecies of Opiliones, and it includes the members of the suborder Laniatores, infraorder Grassatores of the superfamilies Samooidea and Zalmoxoidea plus the genera currently not allocated to any family (i.e. Grassatores incertae sedis). In this Part 2, a total of 556 species and subspecies are listed.Fil: Kury, Adriano Brilhante. Universidade Federal Do Rio de Janeiro. Museu Nacional; BrasilFil: Souza, Daniele R..

Nuevos registros de Geraeocormobius sylvarum (Opiliones, Gonyleptidae, Gonyleptinae) con una destacable disyunción en el noroeste de Aragentina.

Se presentan nuevos registros del opilión Geraeocormobius sylvarum Holmberg (Opiliones, Gonyleptidae, Gonylep- tinae) de las provincias argentinas de Misiones, Corrientes, Chaco y Tucumán, y los estados brasileños de Paraná, Santa Catarina y Río Grande do Sul. La mayor parte de los registros conocidos se localizan en la Provincia Biogeográfica Paranense, en tanto las capturas en el Noroeste argentino representan una disyunción de 640 km entre estas poblaciones y el área principal de la especie (NE de Argentina – SE de Brasil). Se agregan algunos comentarios nomenclaturales y breves consideraciones sobre posibles causas de la disyunción.Several new records of the harvestman Geraeocormobius sylvarum Holmberg (Opiliones, Gonyleptidae, Gonyleptinae) from the Argentinean provinces of Misiones, Corrientes, Chaco and Tucumán, and the Brazilian states of Paraná, Santa Catarina and Rio Grande do Sul are provided. Most known localities spread over the Paranense Biogeographic Province, while captures in northwestern Argentina represent a 640 km disjunction with the species core area (northeastern Argentina - southeastern Brazil). Some nomenclatural comments and a brief discussion on the causes of the disjunction are also given.Fil: Acosta, Luis Eduardo. Consejo Nacional de Investigaciones Científicas y Técnicas.

WCO-Lite: online world catalogue of harvestmen (Arachnida, Opiliones): Version 1.0 — checklist of all valid nomina in Opiliones with authors and dates of publication up to 2018

This Version 1.0 of WCO-Lite contains a hierarchical arrangement of all 8707 valid nomina of taxa in the arachnid order Opiliones, with author and year of publication, including suborders, infraorders, superfamilies, families, subfamilies, genera, subgenera, species and subspecies. Literature survey is meant to be exhaustive up to December 2018, and after that, other works are included as available, but coverage is not necessarily complete. Therefore, some papers up to early 2020 found their way here, especially papers published in leading journals such as Zootaxa, or widely advertised on ResearchGate.Indisponível

An unusual cryptogeobiid from southeastern Brazil revisited (Opiliones, Laniatores, Gonyleptoidea)

The monotypic genus Bunostigma Mello-Leitão, 1935 is herein revisited. A detailed redescription of its type-species, Bunostigma singulare Mello-Leitão, 1935 from Rio de Janeiro state, eastern Brazil, is herein presented, providing in depth knowledge of this genus. Bunostigma is most closely related to Cryptogeobius Mello-Leitão, 1935, and as this genus, it has a stout complex apophysis on male coxa IV, lacking, however, a second complex on the stigmatic area. Bunostigma has an oblique elongate malleus, similar to that of Zalanodius Mello-Leitão, 1936 (as opposed to a globular malleus in Cryptogeobius). Bunostigma singulare has short legs, with some sexual dimorphism on its stoutness, a dorsal scutum entirely unarmed and an ocularium with an accessory central mound, although unarmed
