Cytogenetic studies of three Lycosidae species   from Argentina (Arachnida, Araneae)
Provedor de dados: 74
Autores: 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...

New species of Alpaida (Araneae, Araneidae) from Rondônia, Brazil
Provedor de dados: 76
Autores: Nogueira,André A.; Dias,Stefan R.
ABSTRACT We described a new species of spider, Alpaida clarindoi sp. nov. (Araneidae), from the southwestern Amazon forest. The new species is distinguished from most Alpaida by the presence of a pair of shoulders spines. Females can be separated from similar species by the subquadrangular shape of the epigynum, and males by the shape of the terminal apophysis and the tegulum, which possess an apical pointed tip. Alpaida clarindoi sp. nov. is described based on both sexes.

A new species of Alpaida (Araneae, Araneidae) from Southeastern Brazil
Provedor de dados: 76
Autores: 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.

Three new species of Mesabolivar (Aranea, Pholcidae) from leaf litter in urban environments in the city of São Paulo, São Paulo, Brazil
Provedor de dados: 76
Autores: Machado,Éwerton O.; Brescovit,Antonio D.; Candiani,David F.; Huber,Bernhard A.
In this study we describe three new litter inhabiting species of Mesabolivar González-Sponga, 1998 from nine urban forest remnants in the metropolitan region of the city of São Paulo, Brazil: M. forceps, M. mairyara and M. cavicelatus. In three of these remnants, we conduced a three year sampling using pitfall traps. Mesabolivar forceps sp. nov. was the most abundant pholcid (n=273 adults), always present in the samples, but with highest numbers in spring and summer. Mesabolivar mairyara sp. nov. was the second most abundant species (n=32), but the majority of individuals were collected in March 2001. Only three individuals of M. cavicelatus sp. nov. were collected.

Provedor de dados: 76
Autores: 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...

On Munduruku, a new Theraphosid genus from Oriental Amazonia (Araneae, Mygalomorphae)
Provedor de dados: 76
Autores: Miglio,Laura T.; Bonaldo,Alexandre B.; Pérez-Miles,Fernando.
Munduruku gen. nov. is proposed for the type species Munduruku bicoloratum sp. nov., from Juruti and Santarém, Pará, Brazil. The main diagnostic character of Munduruku gen. nov. is the presence of a subapical, lanceolate keel on the male palpal bulb, which is unique among the basal taxa of Theraphosinae with type III-IV urticating setae. The female spermathecae consist of two spheroid receptacles with funnel-shaped necks, each of which bears a sclerotized area. In both sexes, the abdomen is remarkably patterned, an uncommon feature in adults of New World theraphosids. Both the bulbus lanceolate keel and the abdominal color pattern are hypothesized as synapomorphies of the genus.

Documented bites by a yellow sac spider (Cheiracanthium punctorium) in Italy: a case report
Provedor de dados: 80
Autores: 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
Provedor de dados: 80
Autores: 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...

Description of the male of Yabisi guaba (Araneae: Eresoidea: Hersiliidae)
Provedor de dados: 103
Autores: 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 &amp;amp; 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 &amp;amp; Brescovit, 2004 is described and illustrated and an extended diagnosis is given for the genus.

Provedor de dados: 103
Autores: Pantoja,Paulo; Drago-Bisneto,Marcos; Saturnino,Regiane.
ABSTRACT Berlandiella Mello-Leitão, 1929 is currently composed of six Neotropical species, of which Berlandiella querencia Lise &amp; Silva, 2011 is known only from female specimens; the other species of the genus were described based on both males and females. In this paper, we describe and illustrate Berlandiella zabele sp. nov., based on a few individuals collected in Sete Cidades National Park, Piracuruca and Brasileira, state of Piauí, Brazil. We illustrate and describe the previously unknown male of B. querencia, based on a specimen collected from Reserva Mocambo, Belém, state of Pará, Brazil. The taxa described herein have scopula in the tarsi and metatarsi, and the males have a cymbial process, characters recorded for the first time for the genus....

Redescription and notes on the natural history of the arboreal tarantula Iridopelma seladonium (Araneae: Theraphosidae: Aviculariinae)
Provedor de dados: 104
Autores: Almeida-Silva,Lina M.; Camacho,Agustín; Brescovit,Antonio D.; Lucas,Sylvia M.; Brazil,Tania K.
The original description of this species was based on a single female and no illustrations of reproductive organs were presented. After we collected several specimens identified as I. seladonium, we decided to redescribe this species and discovered that the male, previously described as belonging to this species, was misidentified by MELLO LEITÃO (1923). Thus, in this paper the male of I. seladonium is newly described and the reproductive organs of male and female are described and illustrated in detail. Notes on the behavior and natural history of I. seladonium are presented based on the observation of live specimens in the field and in captivity. An immature of I. seladonium was observed constructing a hinged retreat with silk and little pieces of bark,...

Description of a new species of the spider genus Syntrechalea (Araneae: Lycosoidea: Trechaleidae) from Colombia
Provedor de dados: 104
Autores: Silva,Estevam L. C. da; Lise,Arno A.
A new species of the spider genus Syntrechalea F.O.P.-Cambridge, 1902 is described and illustrated based on material collected in Loreto Mocagua, Colombia. Representatives of this spider genus exhibit an arboreal foraging behavior and are distinguished from the other genera of Trechaleidae by the flattened carapace, long legs and flexible metatarsi and tarsi. New records on the distribution of Syntrechalea tenuis F.O.P.Cambridge, 1902 in Colombia are presented.

Microhabitat selection and co-occurrence of Pachistopelma rufonigrum Pocock (Araneae, Theraphosidae) and Nothroctenus fuxico sp. nov. (Araneae, Ctenidae) in tank bromeliads from Serra de Itabaiana, Sergipe, Brazil
Provedor de dados: 104
Autores: Dias,Sidclay Calaça; Brescovit,Antonio D.
Microhabitat selection and co-occurrence of Pachistopelma rufonigrum Pocock (Theraphosidae) and Nothroctenus fuxico sp. nov. (Ctenidae), in tank bromeliads were investigated. Thermal conditions, inside and outside the plants, were measured in order to verify if the temperature of the water that accumulates inside the plant affects the behavior of these species. Measurements of foliar parameters were taken in order to evaluate if and how plant structure affects spider abundance and microhabitat selection. Apparently, differences in plant structure do not affect either spider abundance or microhabitat selection. No microhabitat preference was observed and co-ocurrence of both species was a random event. In addition, notes on the distribution range of P....

Provedor de dados: 104
Autores: Álvares,Éder Sandro Soares; De Maria,Mário.
Cyrtophora Simon, 1864 comprises 36 species that occur in the Old World and Australia. Cyrtophora citricola (Forskål, 1775) is widespread and has been introduced in the Neotropical region, in Colombia and Hispaniola. Here is presented the first record of this species in Brazil, in the municipalities of Belo Horizonte and Prudente de Morais, State of Minas Gerais. The specimens studied show variations in coloration and in the abdomen's format, but the genital structure is the same as observed in specimens of C. citricola.
