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...

Helsdingen, P.J. van.

The spider fauna of Scragh Bog, a quacking bog in Co Westmeath, Ireland, was investigated for the first time. The presence of 53 species could be established, two of which are new to Ireland (Carorita limnaea (Crosby & Bishop), Porrhomma oblitum (O.P.-Cambridge)), while 30 represent new county records [Philodromus aureolus (Clerck), Tibellus maritimus (Meigen), Misumena vatia (Clerck), Oxyptila trux (Blackwall), Neon reticulatus (Blackwall), Sitticus caricis (Westring), Pirata hygrophilus Thorell, Pirata piscatorius (Clerck), Antistea elegans (Blackwall), Ero cambridgei Kulczynski, Theridion instabile O.P.Cambridge, Metellina mengei (Blackwall), Aphileta misera (O.P.-Cambridge), Araeoncus crassiceps (Westring), Bathyphantes approximatus...

A new species of Argiope (Araneae: Araneidae) from Brazil

Motta,Paulo César; Levi,Herbert W..

A new species of Argiope Audouin, 1826 is described. This is a large Argiope from South America and is found mainly in "cerrado" vegetation in central Brazil. Argiope legionis sp. nov. is most similar to A. ericae LEVI, 2004 but differs from this species by the coloration and epigynum in the female and the median apophysis and embolus of the palpus in the male palp.

Paula,Felipe dos S.; Gabriel,Ray; Indicatti,Rafael P.; Brescovit,Antonio D.; Lucas,Sylvia M..

In this study the Brazilian Amazonian species of Acanthoscurria Ausserer, 1871 are redescribed: A. geniculata (C.L. Koch, 1841), A. tarda Pocock, 1903, A. juruenicola Mello-Leitão, 1923, A. theraphosoides (Doleschall, 1871). Acanthoscurria simoensi Vol, 2000 and A. insubtilis Simon, 1892, previously known from French Guyana and Bolivia, respectively, are recorded for Brazil by the first time. The females of these two species are described for the first time and a new species, A. belterrensis sp. nov., is described from Belterra, Pará, Brazil. In addition, four synonymies are established: A. transamazonica Piza, 1972 as junior synonym of A. geniculata; A. ferina Simon, 1892 and A. brocklehursti F.O.P.-Cambridge, 1896 of A. theraphosoides; and A. xinguensis...

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,...

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...

ABSTRACT Berlandiella Mello-Leitão, 1929 is currently composed of six Neotropical species, of which Berlandiella querencia Lise & 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....

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,...

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 (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....

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.

Ctenus bimaculatus Taczanowski, 1874, is removed from the synonymy of Ancylometes rufus (Walkenaer, 1837) and transferred to the genus Cupiennius Simon, 1891, in which it is placed as a senior synonym of Cupiennius celerrimus Simon, 1891. New records are presented for C. bimaculatus (TACZANOWSKI 1874) and a new species, C. vodou, is described from Haiti.

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.
