A new species of Alpaida (Araneae, Araneidae) from Southeastern Brazil Iheringia, Sér. Zool.
Castanheira,Pedro de S.; Baptista,Renner L. C..
ABSTRACT Alpaida venger sp. nov. is described based on males and females from Pedra Branca State Park, Rio de Janeiro, Brazil. This species seems to be related to Alpaida scriba (Mello-Leitão, 1940) and Alpaida alticeps (Keyserling, 1879) due to similar body shape and color, but is easily distinguished by the very elongated median apophysis, the massive lobe of tegulum and the hooked paracymbium of male palp. Females have elongated epigyne as A. scriba, but can be distinguished by the wider lips and shorter scape.

A new species of Phrixotrichus (Araneae, Theraphosidae) from southwestern Argentina and new distributional data for P. vulpinus Iheringia, Sér. Zool.
Ferretti,Nelson.
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...

Alpaida (Araneae: Araneidae) from the Amazon Basin and Ecuador: new species, new records and complementary descriptions Rev. Bras. Zool.
Saturnino,Regiane; Rodrigues,Bruno V.B.; Bonaldo,Alexandre B..
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,...

Cytogenetic studies of three Lycosidae species from Argentina (Arachnida, Araneae) Genet. Mol. Biol.
Chemisquy,María A.; Gil,Sergio G. Rodríguez; Scioscia,Cristina L.; Mola,Liliana M..
Cytogenetic studies of the family Lycosidae (Arachnida: Araneae) are scarce. Less than 4% of the described species have been analyzed and the male haploid chromosome numbers ranged from 8+X 1 X 2 to 13+X 1 X 2 . Species formerly classified as Lycosa were the most studied ones. Our aim in this work was to perform a comparative analysis of the meiosis in " Lycosa " erythrognatha Lucas, " Lycosa " pampeana Holmberg and Schizocosa malitiosa (Tullgren). We also compared male and female karyotypes and characterized the heterochromatin of " L. " erythrognatha . The males of the three species had 2n = 22, n = 10+X 1 X 2 , all the chromosomes were telocentric and there was generally a single chiasma per bivalent. In " Lycosa " pampeana , which is...

Description of the male of Yabisi guaba (Araneae: Eresoidea: Hersiliidae) Rev. Bras. Zool.
Rheims,Cristina A.; Agnarsson,Ingi; Alayón Garcia,Giraldo.
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...

Diversity, composition and phenology of araneid orb-weavers (Araneae, Araneidae) associated with riparian forests in southern Brazil Iheringia, Sér. Zool.
Rodrigues,Everton N. L.; Mendonça Jr.,Milton de S.; Rodrigues,Patrícia E. S.; Ott,Ricardo.
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...

Documented bites by a yellow sac spider (Cheiracanthium punctorium) in Italy: a case report J. Venom. Anim. Toxins incl. Trop. Dis.
Papini,R.
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.

Evaluation of the efficacy of vacuum cleaners for the integrated control of brown spider Loxosceles intermedia J. Venom. Anim. Toxins incl. Trop. Dis.
Ramires,E. N.; Retzlaff,A. V. L.; Deconto,L. R.; Fontana,J. D.; Marques,F. A.; Marques-da-Silva,E..
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...
