| Parampheres Roewer, 1913 is a relatively common genus of South American harvestmen. This genus is easily diagnosed by the remarkable yellow patches on the prosoma. Nonetheless, species determination within this group is challenging due the convoluted taxonomic history of the group and lack of a recent revision. In this study we revise Parampheres and describe a new species, Parampheres tenebris sp. nov., from Parque Nacional da Serra Geral, Rio Grande do Sul, Brazil. The new species can be distinguished from the other species of the genus by having dorsal scutum dark, and apophysis of coxa IV of male elongated. Furthermore, we propose the following new synonymies: Callampheres boliviensis Roewer, 1913, Pertyana ronae Mello-Leitão, 1927 and Parampheres... |

| Seasonal variations in scorpion activity were investigated during a 24 month period in an area of Caatinga (dryland) vegetation in the state of Paraíba, Brazil. The total number of scorpions captured was correlated with climatic variables and prey abundance. Scorpions were captured monthly using pitfall traps; their potential prey was captured using malaise, beating trays and pitfalls. A total of 104 scorpions were captured, representing four species: the bothriurids Bothriurus asper (Pocock, 1893) (n = 74; 71.2%) and B. rochai (Mello-Leitão, 1932) (n = 20; 19.2%), and the buthids Rhopalurus rochai (Borelli, 1910) (n = 4; 3.8%) and Tityus stigmurus (Thorell, 1876) (n = 1; 1.0%). The sex ratios (male:female) of the two most abundant species were 14:1 for B.... |

| 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... |

| Egg and pupa of Lobeza dentilinea Schaus, 1901 are described and illustrated for the first time. Eggs are smooth, dome-shaped, and greenish at oviposition. Last instar larvae have an aposematic coloration and the chaetotaxy is very similar to other notodontines, except for the number of lateral setae: L. dentilinea has three instead of four lateral setae on abdominal segments A3-A6. Pupae are light brown and typical of the family, with the last abdominal segments broadly round. Evidence from the adult morphology supporting the placement of the genus in Notodontinae includes proboscis smaller than the length of the head, epiphysis with more than half the length of tibia, tarsal claws simple, and labial palpi short. Male and female are confidently... |

| Currently, the Neotropical genus Lepidiella Enderlein, 1937 comprises ten species, only one of them recorded from Brazil. In this paper, two new species of this genus are described from the Atlantic Rainforest of the state of Espírito Santo, Brazil. Lepidiella robusta sp. nov. can be distinguished from all known species by the relative size of the first flagellomere, twice as long the second. Lepidiella flabellata sp. nov. can be distinguished from all known species by the absence of cornicula, cercus with 17 tenacula and pair of inner parameres apically bifurcated. A diagnosis of Lepidiella (species with flagellomeres 1-11 barrel-shaped, bearing simple, unbranched ascoids; flagellomeres 12-14 smaller, without ascoids; wing with acute apex and R4 ending at... |

| In this study we describe the unknown female of Metagonia taruma Huber, 2000, which was discovered after sampling in two forest gap types at Porto Urucu (Urucu River Basin, Coari, Amazonas, Brazil), and also provide information on the community ecology and natural history of the sampled species. The female of M. taruma is similar to that of M. samiria (Huber, 2000) by having an epigynum with a slightly projecting broad scape with a distal pocket; it differs by the larger pore plates. We collected twelve Pholcidae species at Porto Urucu and M. taruma was the most frequent and abundant. The populations of Carapoia ocaina Huber, 2000 and Mesabolivar aurantiacus (Mello-Leitão, 1930) present homogeneous sex ratios, while M. taruma and Mesabolivar sp. were... |

| The knowledge of insect biodiversity in natural areas of Argentina is limited, and termites are among the understudied taxa. In order to assess the diversity of Isoptera in some protected areas of the country, termite sampling within three National Parks of the Northeast region of Argentina was developed during 1995-1999. The results presented in this paper correspond to the Chaco National Park (Province of Chaco), Iguassu National Park (Province of Misiones) and Mburucuya National Park (Province of Corrientes). Among the four termite families recorded from Argentina, the family Termitidae was the best represented at the three sampled areas. The recorded genera (15) were: Rugitermes Holmgren and Tauritermes Krishna (Kalotermitidae), Heterotermes Frogatt... |

| Abracris dilecta Walker, 1870 (Orthoptera, Acrididae, Ommatolampinae) ate leafs of at least 14 plant species, in the families Asteraceae, Lamiaceae, Malvales (Sterculiaceae, Tiliaceae or Malvaceae), Poaceae, Fabaceae, Verbenaceae, Aristolochiaceae, Rubiaceae and Melastomataccae. Elephantopus mollis H.B.K. (Asteraceae) and Hyptis suaveolens Poit. (Lamiaceae) comprised 50% of the diet. The diet breadth of A. dilecta was compared to that of other 11 grasshopper species of the same sub-family, with rarefaction curves. The number of plant species eaten by A. dilecta was greater than that of nine other grasshopper species of the same sub-family (Rhachicreagra spp.) but was lower then two others (Microptylopteryx hebardi Rehn, 1905 and Rhachicreagra astytophallus... |

| Between 1989 and 1995, twenty caves in the Distrito Federal area in mid-western Brazil were assessed for bat species richness, frequency, spatial distribution, behavior, reproduction and inter-specific cohabitation. The general state of conservation of the caves was also assessed. Of the 20 caves studied, 12 were less than 100 m long, five between 100 m and 300 m, and three were longerthan 300 m. Twenty-two species of six different families were observed: 16 species belonged to Phyllostomidae, two to Vespertilionidae and Mormoopidae and one to Furipteridae and Emballonuridae. In this study, 17 species were characterized as Distrito Federal cave dwellers. The most prevalent were Desmodus rotundus, Glossophaga soricina and Carollia perspicillata. The least... |

| Temnocephala trapeziformis sp. nov., ectosymbiont on Trichodactylus fluviatilis Latreille, 1828 is described from the State of Rio Grande do Sul, southern Brazil. Sixty-eight crabs were examined, of which 61 (89.7 %) were positive for this species of the genus Temnocephala Blanchard, 1849. Eggs, as well as adult and young specimens, were found on the pleural areas of the carapace, in the orbital cavities, and, usually, on the fourth pair of pereiopods. The temnocephalans were always devoid of body pigmentation, although they kept the red eye pigment, undiluted in specimens fixed by hot (90ºC) phosphate buffered 10% formalin. The most distinctive characters of the new species are: 1) the shape and size of the cirrus and the characteristics of its introvert... |
