| The original description of Temnocephala iheringi Haswell, 1893 was based on specimens collected by Hermann von Ihering from undetermined ampullariid apple snails, which at that time were identified as Ampullaria sp., and sent to William H. Haswell, with the type locality simply indicated as Brazil. The type specimens studied by Haswell were not found in the scientific collections of Brazil, Europe or Australia, and should be considered lost. In 1941, Pereira & Cuocolo collected specimens from apple snails, identified as Pomacea lineata (Spix in Wagner, 1827), at two localities (Guaicurús and Salobra) in the state of Mato Grosso do Sul, central Brazil. These specimens could not be located either and should, thus, be considered lost as well. Pomacea... |

| The relationship between community structure and environmental factors usually varies according to ecosystem type, group of organisms, and spatial scale. In this study I assessed whether dissimilarities among assemblages of stream macroinvertebrates are related to differences in environmental variables. Data consisted of macroinvertebrate samples of 10 stream sites during the dry season. Seven environmental variables were assessed. The relationship among dissimilarities in assemblage structure and dissimilarities in environmental variables was assessed using the BioEnv approach. Conductivity and measures related to stream size were the most important variables. However, part of the correlation with conductivity was due to the high value observed in a... |

| The adult stages of Nanomis Lugo-Ortiz & McCafferty and Spiritiops Lugo-Ortiz & McCafferty are described for the first time based on reared material from Argentina and Brazil, respectively. They can be differentiated from the other adults of Baetidae by the following characters: Nanomis, hind wings with three longitudinal veins, second vein bifurcate; costal projection of the hind wings pointed, placed in the basal third of anterior margin; and forceps threesegmented, third segment rounded. Spiritiops, fore wings with paired and long marginal intercalary veins; hind wings with three complete longitudinal veins, and an incomplete small longitudinal vein; costal projection of hind wings pointed, broad at base and placed in the basal third of... |

| The genus Helvetia Peckham & Peckham, 1894 is revised. The species H. zebrina Simon, 1901 and H. zonata Simon, 1901 are synonymized with H. cancrimana (Taczanowski, 1872). The species H. insularis (Banks, 1902) is synonymized with H. albovittata Simon, 1901. The genus Deloripa Simon, 1901 is considered a junior synonym of Helvetia by transfer of its type species, resulting in the new combination Helvetia semialba (Simon, 1901). The species Cotinusa humillima Mello-Leitão, 1943, transferred to Helvetia by Galiano, is revalidated. Helvetia roeweri (Soares & Camargo, 1948) comb. nov. is transferred from the genus Naubolus Simon, 1901. The epigynal structures of the type species H. santarema Peckham & Peckham, 1894 and those of H.... |

| Temnocephala minutocirrus sp. nov., an ectosymbiont on Cryphocricos granulosus De Carlo, 1967, is described from the State of Rio Grande do Sul, southern Brazil. One hundred and nine naucorids were examined, of which 36 (33%) were positive for this species of Temnocephala Blanchard, 1849. In one sample of 94 creeping water bugs, 49 (52%) were 4th instar nymphs, 6% of which were infested; 45 (48%) were adults, either brachypterous (40 with 18 males and 22 females) or macropterous (5 with 1 male and 4 females), 67% of which were infested (29% males and 38% females). Temnocephalan eggs were found both ventrally and dorsally: fixed on coxae, trochanters, and along the sternum between fore middle, and hind pairs of legs; basal of the abdominal area; and on the... |

| Thirty eight species are recognized in the Neotropical Region. Twenty four are redescribed and illustrated and fourteen were not redescribed, because they are well definite in the original description. A new combination for Mydaea triseta Curran, 1931 to Phaonia and the revalidation of P. nigripuncta Stein, 1911 are made. Five new synonyms are proposed: P. coquilletii (Vimmer, 1939) = P. punctinervis Stein, 1911; P. nigrocincta Stein, 1918 = P. abdita (Giglio-Tos, 1893); P. praedatoria (Snyder, 1957) = P. latinervis (Stein, 1904); P. vulgata (Albuquerque & Medeiros, 1980) = P. similata (Albuquerque, 1957); P. nigra (Albuquerque & Medeiros, 1980) = P. trispila (Bigot, 1885). A key to the neotropical species is presented for the thirty eight... |

| Two new species of the ant mimicking spider genus Ianduba Bonaldo (Araneae, Corinnidae), I. mugunza sp. nov. and I. abara sp. nov., are described based on males and females from Porto Seguro, in the state of Bahia, Brazil. All specimens were collected in pitfall traps, installed in two forested areas: Estação Ecológica de Vera Cruz, a well preserved Atlantic forest fragment, and a contiguous field of Eucalyptus monoculture. |

| Lissopedia, a new genus is proposed for Tetrapedia globulosa Friese, 1899, from Brazil and to include Tetrapedia flavopicta Cockerell, described from Yucatan, México. Three new species: Lissopedia ochronota from Albany, Jamaica, Lissopedia xanthina from Carmen (on the River Madre de Dios), Pando, Bolívia, and Lissopedia tristriata from Manaus, Amazonas, Brazil are described. The female of Lissopedia globulosa is described from Barreiras, Bahia, Brazil and thus a locality is given for this species. This genus seems to be confined to the Neotropical Region. Exomalopsini, Tapinotaspidini and Paratetrapediini are considered as tribes of Exomalopsinae. |
