| ABSTRACT Epiperipatus edwardsii (Blanchard, 1847) is redescribed based on fresh material collected near the type locality. Additionally, five new species of velvet worms of the genus Epiperipatus Clark, 1913 from Brazil are described: Epiperipatus hyperbolicus sp. nov., Epiperipatus lucerna sp. nov., Epiperipatus titanicus sp. nov. (Holotypes deposited in MNRJ: Murici, Alagoas State), Epiperipatus beckeri sp. nov. (Holotype female deposited in MNRJ: Camacan, Bahia State) and Epiperipatus marajoara sp. nov. (Holotype male deposited in MZUSP: Breves, Marajó island, Pará State). The peculiar shape of the primary papillae (artichoke-like) of E. titanicus sp. nov. and E. beckeri sp. nov. is documented for the first time. Epiperipatus titanicus sp. nov. has the... |

| Temperature affects physiological performance in reptiles and, therefore, body temperature (Tb) control is argued to have an important adaptive value. Alterations in Tb due to transient changes in physiological state, as during digestion or gestation, are often linked to the potential benefits of a more precise Tb regulation. However, such thermoregulatory responses in nature remain controversial, particularly for tropical snakes. Herein, we measured Tb of the golden lanceheads, Bothrops insularis (Amaral, 1921), at Queimada Grande Island, southeastern Brazil, to test for alteration in selected body temperatures associated with feeding or gestation. We found no evidence that postprandial or gravid snakes selected for higher Tb indicating that, under... |

| ABSTRACT Olcyphides cancellatus Redtenbacher, 1906 was described from Canton, China, in error. The species was transferred to Pseudolcyphides Karny, 1923, a genus that later on was synonymized with Malacomorpha Rehn, 1906. However, the name P. cancellatus was forgotten and was not mentioned in the publication where Pseudolcyphides was synonymized with Malacomorpha and thus was not transferred. Here the original geographical record is corrected and the species is transferred to Malacomorpha. The resulting new combination, M. cancellata comb. nov., resulted from examination of specimens from state of Rio Grande do Norte, Brazil. In addition, species diagnosis, redescription of the female and the first description of male specimens, with comparative comments... |

| The outcome of a wild bee fauna survey in a secondary forest is reported. Sampling was carried out mainly on herbaceous and shrubby vegetation under and at the border of the forest. Results are compared with data collected with the same methodology from a previously surveyed grassland nearby. The secondary forest was richer in Anthophoridae and Apidae species, and less diverse in Megachilidae. Similarity between the two habitats was low. Several unidentified species of Ceratinula, Trichocerapis mirabilis and the stingless bees Melipona bicolor, M. quadrifasciata, M. marginata, Paratrigona subnuda, Scaptotrigona tubiba and S. xanthotricha, are among the species dependent on the forest environment to survive. Bee population densities in the forest understory... |

| At a locality near Brasilia the sizes of hunting areas and of colonies of 13 species of social wasps varied greatly. Size of the hunting area varied 152 fold and was strongly related to the number of adult wasps per colony which varied 400 fold. The total number of adults of the 13 species was estimated at 182.9/ ha (range 7.1 fold among the species) and their total biomass was 1.6 kg/ ha (range 3.6 fold). Hunting range was not significantly related to body size. Variation in wing area (11.3 fold) was similar to that of the fresh weight of the adult female (10.7 fold). Eleven species showed habitat preferences where they hunted. Models relating prey size to the distance prey are carried are discussed. |

| The purpose of this study was to describe the composition and abundance of rotifers in different environments: one lotie (the Ivinheima River) and another lentic (the Patos Lake) located in the floodplain of the Upper Paraná River. The influence of limnological variables on the structure and dynamics of rotifers was also examined. Samples were taken monthly from March 1992 through February 1993, in the open water region of the lake and river and in the channel between them and, in the littoral region of the lake and river. Of the 96 species identified, the best represented families were: Brachionidae (20 species), Lecanidae (18 species), and Trichocercidae (15 species). 55 species were widely distributed, 13 were pantropical, 16 neotropical (8 endemic to... |

| A new species of Pickeliana Mello-Leitão, 1932, P. albimaculata sp. nov., is described from Jussari, Bahia, Brazil. It can be easily distinguished from the already described species by the presence of white spots on mesotergal area I and anal opercle. It is similar to P. pickeli Mello-Leitão, 1932 by the presence of a large, ventro-apical pointed tubercle on femora III-IV. A cladistic analysis was performed adding a new character to the available character matrix, the presence of a large and ventro-apical pointed tubercle on male femur IV. According to this analysis, P. albimaculata sp. nov. is sister species of P. pickeli. Additionally, we present an identification key and an update on the geographical distribution of species of this genus in northeastern... |

| Protimesius osvaldoi sp. nov. is described from the Reserva Biológica de Sooretama, state of Espírito Santo, southeastern Brazil, being the first record of Stygnidae from this State and the southernmost record of the family in the Brazilian Atlantic Forest (hitherto, the family was recorded down to Bahia only), extending in 210 km south of the previously known distribution. This is a large species, with armature of leg IV very reduced and penial morphology differing from the closest counterparts mainly in the ventral plate, which recedes deeply at the lateral borders and has the distal margin curved ventrally and by the presence of two small intermediate setae. Protimesius Roewer, 1913 consisted hitherto of 17 species, recorded from northern/northeastern... |

| An important aspect of the hunting strategy of neotropical social wasps (Hymenoptera: Vespidae) is where they hunt. Three species used two behavioural components in their selection of a place to search for prey. The wasps uti lizcd the odour of freshly damaged leaves as cues (which could be synomones) to select which leaves to inspect and also they remembered a place to which they were strongly attracted to hunt recently and returned there. Polybia ignobilis (Haliday, 1836) and Polistes satan Bequaert, 1940 hunted on a lawn of Digitaria diversinervis Stapf immediately after it was mown in significantly larger numbers than at other times. P. ignobilis and Polistes versicolor (Olivier, 1791) hunted in significantly greater numbers on freshly cut leaves of... |
