TL;DR: Changes are made to inconsistencies, mistakes and omissions in the catalogue of American Laniatores by Kury (2003) and Neave’s Nomenclator and the Zoological Record.
Abstract: Amendments are made to inconsistencies, mistakes and omissions in the catalogue of American Laniatores by Kury (2003). Discrepancies between dates given in Kury (2003) and Neave’s Nomenclator and the Zoological Record are discussed. Accurate issue dates for relevant publications are used to define priorities. Etymologies are surveyed for generic names, establishing their grammatical gender, so specific names are inflected according to the provisions of the Code. Unavailable generic names are: Messa Sorensen, 1932, Zarax Sorensen, 1932, Prasia Sorensen, 1932, Angistrisoma Roewer, 1932, Angistrisoma Mello-Leitao, 1935, Bunoweyhia Mello-Leitao, 1935, Batomites Mello-Leitao, 1931, Euminua Sorensen, 1932, Minua Sorensen, 1932, Ilhastygnus Roewer, 1943, Fonteboatus Roewer, 1931, Malea Sorensen, 1932, Chersobleptes Sorensen, 1932 and Jimeneziella Avram, 1970. Hernandria Banks, 1909 is unavailable and must be placed as an “incorrect subsequent spelling” of Hernandaria Sorensen, 1884. The valid genus name is Parahernandria Goodnight & Goodnight, 1947 (stat. res.). Zaraxolia Strand, 1942 (stat. res.) is revalidated from the synonymy of Neocynorta Roewer, 1915 with Zarax devians Sorensen, 1932 as type species. Friburgoia Mello-Leitao, 1932 [December] is deemed a junior subjective synonym of Schenkelibunus Strand, 1932 [September] (stat. res.) (inverted precedence between synonyms). Liops Mello-Leitao, 1940 (non Fieber, 1870, nec Gidley, 1906) is a junior homonym and is replaced by its first available synonym, Corcovadesia Soares & Soares, 1954 (stat. res.). The following unavailable generic names are formally described as new: (1) Jimeneziella Kury & Alonso-Zarazaga, gen. nov. (type species: Jimeneziella decui Avram, 1973); (2) Euminua Kury & Alonso-Zarazaga, gen. nov. (type species: Euminua brevitarsa Sorensen, 1932). The following homonym generic names are replaced: (1) Cranellus Roewer 1932, with Narcellus Kury & Alonso-Zarazaga, nom. nov., (2) Metapachylus Pickard-Cambridge, 1905, with Pyropharynx Kury & Alonso-Zarazaga, nom. nov.; (3) Ovalia Gonzalez-Sponga, 1987, with Oo Kury & Alonso-Zarazaga, nom. nov.; (4) Tiara Gonzalez-Sponga, 1987 with Mitraia Kury & Alonso-Zarazaga, nom. nov.; (5) Limonia Gonzalez-Sponga, 1998, with Manuelangelia Kury & Alonso-Zarazaga, nom. nov. Gonyleptes melloleitaoi Kury & Alonso-Zarazaga, nom. nov. is a replacement name for Gonyleptes curvicornis Mello-Leitao, 1932. Discocyrtus confusus Kury, 2003 is unavailable, so this species is here re-described as Discocyrtus confusus Kury n. sp. New combinations are: Parahernandria spinosa (Banks, 1909) (from Hernandaria), Schenkelibunus impar (Mello-Leitao, 1932) (from Friburgoia), Schenkelibunus perditus (Mello-Leitao, 1927) (from Friburgoia), Narcellus balthazar (Roewer, 1932) (from Cranellus), Narcellus montgomeryi (Goodnight & Goodnight, 1947) (from Cranellus), Pyropharynx gracilis (Pickard-Cambridge, 1905) (from Metapachylus), Oo spinosum (GonzalezSponga, 1999) (from Ovalia), Mitraia unispina (Gonzalez-Sponga, 1987) (from Tiara), Manuelangelia tuberosa (Gonzalez-Sponga, 1998) (from Limonia), Zaraxolia devians (Sorensen, 1932) (from Zarax), Corcovadesia hexabunus (Mello-Leitao, 1940) (from Liops) and Corcovadesia venefica (H. Soares, 1966) (from Liops). The following genera of Pachylinae, which appeared in conflicting subfamilies in Kury 2003, are formally transferred to the Ampycinae: Ampycella Roewer, 1929, Glysterus Roewer, 1931, Hernandarioides Pickard-Cambridge, 1905, Parahernandria Goodnight & Goodnight, 1947 and Hutamaia Soares & Soares, 1977. A list of taxa described in 2003 is interpolated. A complementary list of the 2004–2009 systematic literature on the subject is given.
TL;DR: The internal phylogeny of the Opiliones is robust to parameter choice and allows the discarding of previous hypotheses of opilionid phylogeny such as the “Cyphopalpatores” or “Palpatores,” and resolution within the Eupnoi, Dysp noi, and Laniatores is also stable to the superfamily level, permitting a new classification system for the opiliones.
Abstract: Karos Goodnight & Goodnight, 1944 is the most diverse genus of the family Stygnopsidae. It contains seven micro-endemic species from the Huasteca region in eastern Mexico. In this paper, the new species Karos morronei sp. nov. is described based on the morphology of adults of both sexes. The new species is from Zacualtipan de Angeles, Hidalgo State, which represents the southernmost record for the genus. Additionally, a reanalysis of the previous morphological phylogeny of the genus using both parsimony and maximum likelihood methods is provided. According to the morphological reanalysis, K. morronei sp. nov. exhibits an autapomorphy (males with femur IV thicker than females) and is the sister group of the clade that includes K. barbarikos , K. hexasetosus, K. monjarazi , K. parvus and K. singularis . Finally, information of barcoding (CO1) is provided for this new species.
TL;DR: Age estimates for the main Opiliones lineages suggest a Carboniferous diversification of Cyphophthalmi, while its sister group, Phalangida, diversified in the Early Devonian, and most major lineages predate the Cretaceous.
TL;DR: The Opiliones Collection at the Museu Paraense Emílio Goeldi showcases the diversity and vulnerability of these creatures.
Abstract: Are harmless arachnids cryptic and nocturnal habits of most species. Usually live under logs, stones, leaves and litter, buried or in bromeliads on leaves and stems or roots of living plants, and may also inhabit caves. Are highly diverse and abundant in tropical regions of the world, with 6,476 species (Kury, 2011). Are very sensitive animals that have a high degree of endemism and limited dispersal ability, thus being a group with high potential for extinction. The Neotropics has the largest percentage of the world's wealth of harvestmen (57%) of which 41% are in Brazil (938 species).
