Biologia de nidificação de Anthodioctes megachiloides Holmberg (Anthidiini, Megachilidae, Apoidea) Zoologia
Alves-dos-Santos,Isabel.
Anthodioctes megachiloides Holmberg, 1903 é uma abelha solitária que utiliza cavidades pré-existentes para construir o ninho. Ninhos armadilhas de madeira foram instalados no jardim do Laboratório de Abelhas no campus da Universidade de São Paulo. As armadilhas consistiram de orifícios circulares de 4 a 5 mm de diâmetro, com profundidade de 5 a 7 cm. Tubos de papel foram inseridos nos orifícios de tal maneira que pudessem ser posteriormente e periodicamente inspecionados. Dados sobre a biologia, construção de ninho, comportamento da fêmea e atividade dos parasitas foram obtidas através de observações diretas durante a primavera e verão de 2001/2002. Fêmeas de A. megachiloides iniciaram atividade em meados de agosto e fundaram um total de 40 ninhos na...

Characterization and discrimination of three Rhopalosiphum species (Homoptera: Aphididae) based on isozymes Zoologia
Lázzari,Sonia M. N..
Seventeen clones of Rhopalosiphum padi (Linnaeus, 1758), 14 of R. maidis (Fitch, 1856), and two of R. insertum (Walker, 1849), representing a wide range of host plants and geographic distribution, were examined electrophoretically to determine intra and interspecific variation. Twenty-one enzyme systems were tested using starch-gel techniques. The electromorph variation within species was low, as expected for parthenogenetic organisms. Frequency of heterozygotes was also relatively low for most populations. The percentage of polymorphic loci ranged from 0% to 27.3% in R. padi, but it was lower (0% to 18.2%) in the completely an holocyclic R. maidis. No consistent correlation between band patterns and host plant or geographic origin could be established for...

Embriogenesis and larval ontogeny of the "piau-gordura", Leporinus piau (Fowler) (Pisces, Anostomidae) after induced spawning Zoologia
Borçato,Fábio Luiz; Bazzoli,Nilo; Sato,Yoshimi.
Mature males and females of Leporinus piau (Fowler, 1941) were induced to reproduce through a hypophysation process. Extrusion occurred 12 h or 312 hours-degree after the hypophysation, at a water temperature of 26°C. Fertilized eggs were maintained in incubators at 24°C. Embryonic development, was evaluated using every 10 minutes, fresh egg samples which were analyzed under stereoscopic microscope. The larvae were collected at 24-hour intervals for seven days after hatching, fixed in Bouin's fluid and were submitted to routine histological techniques. The eggs of L. piau were slightly gray, non-adhesive and round-shaped. After 1.5 h the embryo was at the 64-blastomere phase and showed a wide yolk region on the vegetative pole. Within 6.25 h, blastopore...

Fine structure of the retinal pigment epithelium and cones of Antarctic fish Notohenia coriiceps Richardson in light and dark-conditions Zoologia
Donatti,Lucélia; Fanta,Edith.
The Antarctic fish Notothenia coriiceps Richardson, 1844 lives in an environment of daily and annual photic variation and retina cells have to adjust morphologically to environmental luminosity. After seven day dark or seven day light acclimation of two groups of fish, retinas were extracted and processed for light and transmission electron microscopy. In seven day dark adapted, retina pigment epithelium melanin granules were aggregated at the basal region of cells, and macrophages were seen adjacent to the apical microvilli, between the photoreceptors. In seven day light adapted epithelium, melanin granules were inside the apical microvilli of epithelial cells and macrophages were absent. The supranuclear region of cones adapted to seven day light had...

Revision of the genus Neoscolecithrix (Copepoda, Calanoida) and description of N. caetanoi, sp. n., collected off Brazil Zoologia
Alvarez,Maria Paloma Jimenez.
The genus Neoscolecithrix is redefined and its situation in the family is discussed. The division of the species of this genus into two groups, "kehleri" and "farrani", is proposed, based on marked differences in the type of the rostrum, in the mandible's gnathobase, in the maxilla 2 and in the legs, especially the fifth leg. Xanthocalanus watersae Grice (1972) is considered a species of Neoscolecithrix. The female and the male of N. caetanoi sp. n., collected off the Brazilian coast at 900 m depth, are described.

Mnesarete mariana nova espécie de libélula da Chapada Diamantina, Bahia, Brasil (Odonata, Calopterygidae) Zoologia
Machado,Ângelo B.M.
Mnesarete mariana sp.n. is described based on three male specimens collecled at Chapada Diamantina, in the Bahia State, Brazil. The new species is close to M. guttifera (Selys, 1873) but differs from it mainly by structure of the inferior anal appendages and by the presence of a tuft of hairs on each side of the hind part of the anterior lamina adjacent to the anterior hamuli. The appendages of M. guttifera are now illustrated for the first time.

Levantamento da fauna de abelhas silvestres na "zona da mata" de Minas Gerais: III. Mata secundária na região de Viçosa (Hymenoptera, Apoidea) Zoologia
Cure,José Ricardo; Thiengo,Marciana; Silveira,Fernando A.; Rocha,Luis B..
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...

Phaonia Robineau-Desvoidy (Diptera, Muscidae, Phaoniinae): II: revisão das espécies Zoologia
Coelho,Sônia Maria Prevedello.
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).

Kihara,Terue C.; Björnberg,Tagea K. S.; Kawauchi,Gisele Y..
Catiniid copepods are characterized by the presence of a pedunculate sucker on the antenna. Four genera are currently included in the family Catiniidae: Catinia, Cotylemyzon, Cotylomolgus and Myzomolgus, the most speciose. Within the framework of the Special Research Program "Conservation and Sustainable Use of the Biodiversity of the State of São Paulo - Biota/FAPESP", a new species of Myzomolgus was found as an external associate of Sipunculus nudus and S. phalloides phalloides. The sipunculan worms were collected during the low tide in Araçá Beach, State of São Paulo, Brazil (23º49’02"S, 45º24’19"W). The new species differs from its three congeners, namely M. stupendus from France and M. tenuis and M. orientalis from Korea, by the peculiar ornamentation...
