This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The genus Meriola Banks currently includes 24 known species of spiders distributed across America, especially in southern South America. They have a nearly straight and narrower posterior eye row compared to other American genera of Trachelidae, and elongated and sharply tipped ventral leg cuspules. The study of specimens of Meriola available in collections revealed two undescribed species, M. avalosi sp. nov. and M. peras sp. nov., and the previously unknown females of M. balcarce Platnick & Ewing and M. quilicura Platnick & Ewing, all of which are described here. The female of M. lineolata (Mello-Leitão) comb. nov., transferred from Cetonana Strand, is described for the first time. Two further new combinations are proposed here: M. macrocephala (Nicolet) comb. nov., transferred from Trachelopachys Simon, and M. setosa (Simon) comb. nov., transferred from Cetonana; these two species are also considered senior synonyms of M. barrosi (Mello-Leitão) and M. hyltonae (Mello-Leitão), respectively. Additionally, a new sex matching of M. ramirezi Platnick & Ewing and M. davidi Grismado is proposed, with a redescription of the female of M. ramirezi provided. New geographical records are provided for all of the species, with images and a revised diagnosis for the genus and the previously known species. Keywords: new spider species, South America, taxonomy, new records, Dionycha"--Page 4.

This book was released on 2015 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: We review the American spider genus Arachosia O.P.-Cambridge, and present a descriptive taxonomic study with a comparative dichotomous key including 21 species, of which seven are newly described (A. avalosi sp. nov., A. carancho sp. nov., A. kapiipeoi sp. nov., A. magna sp. nov., A. monserrate sp. nov., A. pinhalito sp. nov. and A. tungurahua sp. nov.). Four species names are considered nomina dubia: Oxysoma dubium Berland, Gayenna duplovittata Mello-Leitão, Oxysoma polytrichium Mello-Leitão, and Arachosia sulfurea Mello-Leitão. Arachosia bonneti (Mello-Leitão) is newly synonymized with A. albiventris Mello-Leitão, and A. mezenioides Mello-Leitão with A. freiburgensis Keyserling. Previous problems with the identification of species in a species complex including A. cubana (Banks) are resolved. A disjunct distributional pattern is reported for A. kapiipeoi sp. nov.; a preliminary phylogenetic analysis based on mitochondrial COI sequences shows that these may correspond with two cryptic species. In this contribution, grassland and forests are discussed as the two main habitats inhabited by species of Arachosia. Finally, we propose a hypothesis of matching sexes based on functionality of some genital structures, involving sclerites of the male copulatory organ with structures of the epigyne: the prolateral projection on the primary conductor of the male would have a direct interaction with the lateral projections of the anterior pouch on the median epigynal field of females. Key words: Spider, American, Araneae, Anyphaenidae.

This book was released on 2015 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elaver O. Pickard-Cambridge, 1898 is characterized and redescribed, including 49 species occurring from the United States to Argentina. Thirty seven previously known species are redescribed: Elaver achuca (Roddy, 1966) revalidated, E. balboae (Chickering, 1937), E. barroana (Chickering, 1937), E. calcarata (Kraus, 1955), E. carlota (Bryant, 1940), E. chisosa (Roddy, 1966), E. crinophora (Franganillo, 1934), E. crocota (O. Pickard-Cambridge, 1896), E. albicans(Franganillo, 1930) name restored, E. depuncta O. Pickard-Cambridge, 1898, E. elaver (Bryant, 1940), E. excepta (L. Koch, 1866), E. grandivulva (Mello-Leitão, 1930), E. hortoni (Chickering, 1937), E. implicata (Gertsch, 1941), E. juana(Bryant, 1940), E. kohlsi (Gertsch & Jellison, 1939), E. linguata (F.O. Pickard-Cambridge, 1900), E. madera (Roddy, 1966), E. mirabilis (O. Pickard-Cambridge, 1896) new. comb., E. mulaiki (Gertsch, 1935), E. multinotata (Chickering, 1937), E. orvillei (Chickering, 1937), E. placida O. Pickard-Cambridge, 1898, E. portoricensis (Petrunkevitch, 1930), E. quadrata (Kraus, 1955), E. richardi (Gertsch, 1941), E. sericea O. Pickard-Cambridge, 1898, E. sigillata (Petrunkevitch, 1925), E. simplex (O. Pickard-Cambridge, 1896), E. texana (Gertsch, 1933), E. tigrina O. Pickard-Cambridge, 1898 namerestored, E. tricuspis (F.O. Pickard-Cambridge, 1900), E. tristani (Banks, 1909), E. tumivulva (Banks, 1909), E. valvula(F.O. Pickard-Cambridge, 1900) and E. wheeleri (Roewer, 1933). Ten new species are described: E. candelaria n. sp. andE. helenae n. sp. from Mexico; E. arawakan n. sp. from Haiti; E. lizae n. sp. from Costa Rica; E. darwichi n. sp. fromEcuador; E. juruti n. sp., E. tourinhoae n. sp. and E. vieirae n. sp. from Brazil; E. shinguito n. sp. from Peru and E. beni n. sp. from Bolivia. The female of E. hortoni is described for the first time. Lectotypes are designated for E. sigillata and its actual female is described for the first time. Four new synonyms are proposed: E. languida (Gertsch, 1941) is synonimized with E. multinotata; E. dorothea (Gertsch, 1935) with E. wheeleri; E. exempta (Gertsch & Davis, 1940) with E. placida and E. vulnerata (Kraus, 1955) with E. calcarata. The drawings in the original descriptions of E. kawitpaaia (Barrion & Litsinger, 1995) and E. turongdaliriana (Barrion & Litsinger, 1995) are sufficiently informative to exclude these species from Elaver but not to accurately establish its generic affiliation. Thus, until the types become available for examination, these species must remain as Clubionidae incertae sedis. Heterochemmis (F.O. Pickard-Cambridge, 1900) is synonymized with Elaver and Heterochemmis mutatus Gertsch & Davis,1940 is recognized as a junior synonym of Elaver mirabilis n. comb., the type species of Heterochemmis. New records are presented for E. valvula, E. balboae, E. brevipes(Keyserling, 1891), E. grandivulva and E. lutescens (Schmidt, 1971). Two species described by Franganillo, E. tenera(Franganillo, 1935) and E. tenuis (Franganillo, 1935), are considered species inquirendae.

This book was released on 2013 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genera Agyneta Hull 1911 and Tennesseellum Petrunkevitch 1925 are revised for North America north of Mexico. The synonymy of Meioneta Hull 1920 with Agyneta Hull 1911 proposed by Saaristo 1973 is corroborated. The North American fauna north of Mexico of Agyneta now includes a total of 69 species, of which 31 are new species: A. watertoni n. sp., A. perspicua n. sp., A. aquila n. sp., A. yukona n. sp., A. darrelli n. sp., A. bucklei n. sp., A. erinacea n. sp., A. crawfordi n. sp., A. vinki n. sp., A. panthera n. sp., A. miniata n. sp., A. danielbelangeri n. sp., A. pistrix n. sp., A. flax n. sp., A. barfoot n. sp., A. sandia n. sp., A. spicula n. sp., A. grandcanyon n. sp., A. chiricahua n. sp., A. crista n. sp., A. tuberculata n. sp., A. catalina n. sp., A. ledfordi n. sp., A. platnicki n. sp., A. bronx n. sp., A. paquini n. sp., A. girardi n. sp., A. flibuscrocus n. sp., A. delphina n. sp., A. okefenokee n. sp. and A. issaqueena n. sp. The genus Tennesseellum includes two species, with one new species, T. gollum n. sp. Ten new synonyms are recognized: Meioneta grayi Barnes 1953 = Anibontes mimus Chamberlin 1924; Meioneta dactylata Chamberlin & Ivie 1944, Meioneta officiosa (Barrows 1940) = Meioneta micaria (Emerton 1882); Meioneta imitata Chamberlin & Ivie 1944 = Meioneta leucophora Chamberlin & Ivie 1944; Meioneta ferosa (Chamberlin & Ivie 1943) = Meioneta fillmorana (Chamberlin 1919); Meioneta fuscipes Chamberlin & Ivie 1944 = Meioneta floridana (Banks 1896); Meioneta alaskensis Holm 1960 = Meioneta maritima (Emerton 1919); Meioneta meridionalis (Crosby & Bishop 1936), Meioneta zebrina Chamberlin & Ivie, 1944 = Meioneta parva (Banks 1896); Meioneta zygia (Keyserling 1886) = Meioneta fabra (Keyserling 1886). Ten informal species groups are proposed based on the study on the male palpal conformation of the embolus and radical division; these groups are not intened to be phylogenetic hypotheses. The limits and composition of the subfamily Micronetinae sensu Saaristo & Tanasevitch 1996 are discussed.
