Available in PDF, EPUB and Kindle. Book excerpt: A cladistic phylogenetic analysis at generic level of the subfamily Amaurobioidinae is presented. The analysis is based on a dataset of 93 representative species scored for one behavioral and 199 morphological characters. Tree searches were made under equal and implied weights according to homoplasy, and the results were compared in terms of sensitivity to jackknife resampling. Mildest weighting functions produced trees more robust to resampling, and those results were selected as the working phylogenetic hypotheses. Groups of weak support as identified by jackknifing and Bremer indices are in general those that vary in resolution with different character-weighting schemes. Seven outgroup representatives were included (Malenella nana Ramírez, from Malenellinae, and six Anyphaeninae species). In this analysis Anyphaeninae, previously identified as sister group of Amaurobioidinae, is paraphyletic, but forcing its monophyly does not alter the groupings within Amaurobioidinae. The monophyly of the genera is in general well supported, but some particularly conflicting groups are discussed. In contrast, the relationships among genera are in general problematic. Amaurobioidinae is diagnosed by a pronounced indentation at the base of male palpal tegulum, and by a particular male copulatory bulb conformation, with a paramedian apophysis. The subfamily is classified in two tribes (Gayennini and Amaurobioidini); the genus Josa Keyserling, probably sister group to Gayennini, is not assigned to either tribe. The tribe Amaurobioidini is mainly diagnosed by an apical loop of the sperm duct in the male copulatory bulb. It includes 10 genera: Amaurobioides O.P.-Cambridge is restricted to seashores of southern continents. Clubiona chilensis Nicolet, transferred to Amaurobioides, is the first true record of the genus for South America. The male of Axyracrus elegans Simon, three species of Aysenia Tullgren, and three of Coptoprepes Simon are newly described. Four new genera are proposed in Amaurobioidini: Gamakia, Selknamia (described for one new species each), Aysenoides (for three new species), and Negayan (type species Gayenna tridentata Simon, including also Axyracrus coccineus Mello-Leitão, Clubiona paduana Karsch, Gayenna excepta Tullgren, Gayenna exigua Mello-Leitão, and Tomopisthes lebruni Simon). The previously revised genera Acanthoceto Mello-Leitão and Ferrieria Tullgren are also included in the tribe. The basal branch and most intergeneric branches of the tribe have low support values. Amaurobioides and Negayan, however, are relatively well supported. The tribe Gayennini is well defined by a homogeneous conformation of male and female genitalia, with a distinctive secondary conductor and spherical spermathecae. It includes 11 genera: Gayenna Nicolet includes only G. americana Nicolet from Chile and adjacent Argentina. Arachosia O.P.-Cambridge comprises many species previously assigned to Oxysoma. Abuzaida striata Keyserling, Anyphaena oblonga Keyserling, Gayenna proseni Mello-Leitão, Gayenna duplovittata Mello-Leitão, Gayenna bonneti Mello-Leitão, Oxysoma dubium Berland, Oxysoma bifasciatum Mello-Leitão, Oxysoma cubana Banks, Oxysoma polytrichium Mello-Leitão, Phidyle bergi Simon, and Samuza praesignis Keyserling are transferred to Arachosia. The males of Arachosia bergi (Simon), A. honesta Keyserling, and Arachosia praesignis (Keyserling) are newly described. Arachosia is easily recognized by the thick setae on the anterior lateral spinnerets, and it has good support values. A very diverse group of species here assigned to the genus Sanogasta Mello-Leitão is paraphyletic in terms of Arachosia. It includes many of the species formerly placed in Gayenna Nicolet. Anyphaena maculatipes Keyserling, Clubiona maculosa Nicolet, Gayenna paucilineata Mello-Leitão, Gayenna alticola Simon, Gayenna bonariensis Mello-Leitão, Gayenna rufithorax Tullgren, Gayenna x-signata Keyserling, Gayenna approximata Tullgren, Samuza minuta Keyserling, and Tomopisthes backhauseni Simon are transferred to Sanogasta. The female of Sanogasta alticola (Simon), the males of S. x-signata (Keyserling) and S. approximata (Tullgren), and four species are newly described. The males of Monapia carolina Ramírez and Monapia angusta (Mello-Leitão) are newly described. A new species of Oxysoma Nicolet from southern Brazil is described, and Gayenna saccata Tullgren is transferred to Oxysoma. Phidyle Simon is removed from the synonymy of Oxysoma Nicolet; the male of its only species Phidyle punctipes (Nicolet) is newly described. The genus Philisca Simon is redefined to include Liparotoma Simon. Clubiona tripunctata Nicolet and Clubiona gayi Nicolet are also transferred to Philisca. The male of Philisca hahni Simon and two species are newly described. The genus is reasonably supported, except for one basal species of questionable placement. Anyphaena punctata Keyserling, Gayenna fuscotaeniata Keyserling, Gayenna tripunctata Mello-Leitão, Gayenna reticulata Mello-Leitão, Gayenna taperae Mello-Leitão, Oxysoma quinquenotatum Simon, Oxysoma unipunctatum Simon, Oxysoma novum Mello-Leitão, Oxysoma lineatum Tullgren, and Tomopisthes frenatus Mello-Leitão are transferred to Tasata. The males of Tasata parcepunctata Simon, T. variolosa Mello-Leitão, and three species are newly described. Tasata albofasciata Mello-Leitão is transferred to Tupirinna Bonaldo, in the Corinnidae. Tomopisthes Simon includes only three species from Chile and adjacent Argentina. Clubiona horrenda Nicolet and Clubiona pusilla Nicolet are transferred to Tomopisthes. The male of Tomopisthes pusillus (Nicolet) is newly described. Two new genera are proposed in Gayennini: Araiya (Gayenna pallida Tullgren, type species and Gayenna coccinea Simon) and Gayennoides (for two new Chilean species). The genus Josa Keyserling, distinguished by a femoral apophysis on the male palp, is extremely diverse in Andean cloud forests and tropical America. It is one of the better supported groups of the analysis. Anyphaena keyserlingi L. Koch, Gayenna andesiana Berland, Gayenna simoni Berland, Gayennella riveti Berland, Haptisus nigrifrons Simon, Haptisus analis Simon, Haptisus maurus Simon, Olbophthalmus lojensis Berland, Olbus personatus Simon, Olbus gounellei Simon, Tetromma luteum Keyserling, and Tomopisthes chazaliae Simon are transferred to Josa. The male of Josa riveti (Berland) and one species are newly described.

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.
