| ABSTRACT A new species of Phrixotrichus Simon, 1889, P. pucara sp. nov., is described and illustrated based on a male from Pucará river, Neuquén province, Argentina. Male can be distinguished from all other species of the genus by the presence of a long strong spine on inner face of prolateral branch of tibial apophysis; also, it differs from P. scrofa (Molina, 1788) and P. vulpinus (Karsch, 1880) by a serrated prolateral keel of the male palpal bulb. Male resembles P. jara Perafán & Pérez-Miles, 2014 but can be distinguished by the uniform color on dorsal cephalothorax and by the palpal organ morphology being wider on the bulb base and embolus shorter and thicker, with the tip of embolus not so directed retrolaterally and prolateral keel bearing a... |

| Two new species of Alpaida, A. levii and A. yanayacu, the male of A. iquitos Levi, 1988 and the female of A. gurupi Levi, 1988 are described and illustrated for the first time. Alpaida levii, described from the states of Pará and Amazonas, is closely related to A. delicata (Keyserling, 1892), but differs in that males have a curved and distally pointed terminal apophysis, and females have the epigynum longer than wide and a drop-shaped median lobe. Alpaida yanayacu is only known from Ecuador and is characterized by long and rounded lateral lobes in ventral view and median lobe wide at base. A brief discussion about the morphological similarity among A. levii, A. delicata and A. truncata (Keyserling, 1865) is presented. Based on the information provided,... |

| The spider fauna composition of three rubber tree commercial plantations in the Northwest part of São Paulo State, Brazil, was characterized for both canopy and litter strata. On seven occasions from April 2000 to October 2001, samples were taken by beating sheet and hand capture, resulting in a total of 946 individuals, belonging to 24 families and 119 species. The most common species were Italaman santamaria Brescovit, 1997 and Teudis sp. (Anyphaenidae), Castianeira sp. and Falconina aff. gracilis (Corinnidae), Paracleocnemis sp. (Philodromidae), Ibotyporanga naideae Mello-Leitão, 1944 (Pholcidae), Chira spinipes (Taczanowiski, 1871) and Rudra sp. (Salticidae), Achaearanea hirta (Taczanowiski, 1873) and Coleosoma floridanum (Banks, 1900) (Theridiidae)... |

| The male of Mangora brokopondo Levi, 2007 is described and illustrated for the first time. Variation in the color pattern of the females is documented. Mangora woytkowskii Levi, 2007 is considered a junior synonym of M. hirtipes (Taczanowski, 1878). New records of M. alinahui Levi, 2007 and M. pia Chamberlin & Ivie, 1936 are presented. |

| Hersiliidae is a relatively small spider family that is easily distinguished by the very long posterior lateral spinnerets. It is distributed worldwide and, although quite diverse in other zoogeographical regions, is represented by only 11 species in the Neotropics. Hersiliidae was recently revised and of the 11 species, three are known solely from one sex. Yabisi Rheims & Brescovit, 2004 includes only two species, one of which is known solely from the female. The genus is extremely rare and both species are known from only a few specimens. In this paper, the male of Yabisi guaba Rheims & Brescovit, 2004 is described and illustrated and an extended diagnosis is given for the genus. The male of this species is distinguished from its congener... |

| Two new species of Plesiopelma Pocock, 1901 from northern Argentina are described and diagnosed based on males and habitat descriptions are presented. Males of Plesiopelma paganoi sp. nov. differ from most of species by the absence of spiniform setae on the retrolateral face of cymbium, aspect of the palpal bulb. Plesiopelma aspidosperma sp. nov. differs from most species of the genus by the presence of spiniform setae on the retrolateral face of cymbium and it can be distinguished from P. myodes Pocock, 1901, P. longisternale (Schiapelli & Gerschman, 1942) and P. rectimanum (Mello-Leitão, 1923) by the separated palpal bulb keels and basal nodule of metatarsus I very developed. It differs from P. minense (Mello-Leitão, 1943) by the shape of the... |

| The Araneidae is a speciose family including web-spinning spiders that are very abundant in various terrestrial ecosystems. Several studies demonstrate that changes in vegetation surrounding rivers, streams and brooks affect the associated araneofauna. The aim of this research was to compare differences found in diversity (abundance and richness), composition and phenology of Araneidae spiders sampled in different habitats in four riparian forest catchments in southern Brazil. Samples were taken from riparian forests in four rivers of Rio Grande do Sul State: Piratini, Camaquã, Sinos and Maquiné rivers, each in a different hydrographic basin. Samples were taken twice seasonally on each basin during two years, sampling the araneofauna of the tree-shrub... |

| In Italy reports of human envenomations by yellow sac spiders have been sporadic. Since increasing clinical information would improve understanding of the danger of yellow sac spiders to humans, we report the case of a 7-year-old child and her father bitten by a documented Cheiracanthium punctorium. They developed acute persistent pain with local skin signs and numbness, and required emergency treatment. The father recovered completely within 1 to 2 hours and the child within 3 to 4 days after treatment, probably as a result of spontaneous evolution. Clinicians should be aware of the risks and immediate management of spider bites. |

| Some venomous spiders of the genus Loxosceles can reach high population densities inside and around houses. In Brazil, most spider accidents are related to Loxosceles intermedia. Control of loxoscelism should utilize integrated pest management tools, such as vacuum cleaners, to eliminate egg sacs, webs and spiders. The present study tested the efficacy of one type of vacuum cleaner (for professional and domestic use) in the control of L. intermedia populations. Cockroaches (Pycnoscelus surinamensis) were used in some tests for comparison. Vacuuming using standard accessories or a paper tube resulted in the death of all female (n=60), male (n=60), young (n=60) and just-hatched (n=60) L. intermedia, and all egg sacs (n=5) were destroyed. The removal of the... |
