Actinopterygii, Siluriformes, Loricariidae, Loricariichthys platymetopon Isbrucker and Nijssen, 1979: first record in Reservoir of Canoas II, Middle Paranapanema River, border of the states of São Paulo and Parana, Brazil.

First record of the cascudo, Loricariichthys platymetopon Isbrucker and Nijssen, 1979 in Canoas II Reservoir (Middle Paranapanema River, border of the states of São Paulo and Parana, Brazil). Its occurrence is due to the flooding of Sete Quedas waterfall, as a result of the construction of Itaipu Reservoir. Furthermore, there is absence or low abundance of natural predators, like Salminus brasiliensis, since this species has difficulties to adapt or even survive in reservoirs.

New record of Haplometroides intercaecalis (Digenea, Plagiorchiidae) infecting a Brazilian snake

Phalotris matogrossensis (Serpentes, Colubridae) was reported as a new host for Haplometroides intercaecalis ( Digenea, Plagiorchiidae). The host snake was obtained from the municipality of Anastacio, state of Mato Grosso do Sul, Brazil. One specimen of H. intercaecalis was recovered from the esophagus of the host and identified by the intercecal position of the vitellaria in the pre-acetabular region. This paper describes the second report of the occurrence of this trematode in fossorial snakes of the genus Phalotris in the state of Mato Grosso do Sul, Brazil.

Reptilia, Squamata, Dipsadidae, Xenodontinae, Taeniophallus brevirostris (Peters, 1863): distribution extension and new state record.

Taeniophallus brevirostris is a dipsadid snake widely distributed in Amazon. Here we report a new Brazilian state record for the species, improving our knowledge of its geographic distribution. 0n 15 May of 2008, one female specimen was collected do Serra do Santo Expediot, Aripuana municipality, state of Mato Grosso, Brazil. This is the first record of this species for the state of Mato Grosso and extends its distribution ca. 300 kilometers from the nearest localities presented in literature.

First record of Amblyomma rotundatum Koch, 1844 (Acari: Ixodidae) parasitizing Paleosuchus palpebrosus Cuvier, 1807 (Reptilia: Crocodylidae), in the western border of Pantanal, Mato Grosso do Sul, Brazil.

This is the first record of Amblyomma rotundatum parasitizing Paleosuchus palpebrosus. This record was made during a herpetofaunal study carried out in high-elevation habitats that are under protection in the mountain range "Serra do Amolar", located in the western border of Brazilian Pantanal, in the state of Mato Grosso do Sul.

Chromosomal data of two pholcids (Araneae, Haplogynae): A new diploid number and the first cytogenetical record for the New World Clade

Mesobolivar luteus (Keyserling 1891) and Micropholcus fauroli (Simon 1887) specimens were collected in Ubatuba and Rio Claro, both in the state of São Paulo, Brazil. Mesabolivar luteus showed 2n (male) = 15 = 14 + X and 2n (9) = 16 = 14 + XX in mitotic metaphases and 711 + X in diplotenic cells. During late prophage 1, all bivalents presented a ring shape, evidencing two chiasmata per bivalent. In this species, some diplotenic cells appear in pairs, maybe due to specific characteristics of the intercellular bridges. The metaphases 11 showed n = 7 or n = 8 = 7 + X chromosomes. Micropholcus fauroti evidenced 2n (male) = 17 = 16 + X in spermatogonial metaphases and 8II+X in diplotenic cells, with only one chiasma per bivalent, contrasting with M. luteus. In both species, all chromosomes were metacentrics. The sexual chromosome X was the largest element and appeared as a univalent during meiosis I. These are the first cytogenetical data for the genera Mesabolivar and Micropholcus. Additionally, M. luteus is the first chromosomally analyzed species of the New World clade and the observed diploid number for M. fauroti had not yet been recorded in Pholcidae.

Record of a gregarine (Apicomplexa : Neogregarinida) in the abdomen of the termite Coptotermes gestroi (Isoptera, Rhinotermitidae)

Coptotermes gestroi is an exotic species of termite that is a pest of great economical importance in Brazil. This paper relates the occurrence of a coelomic gregarine (Apicomplexa: Neogregarinida) in the abdomen of the foraging workers recently collected from field colonies of this termite. The termite hosts presented large, white abdomens because they carried 1 up to 3 cysts of gregarines filled with numerous lemon-shaped spores. Earlier developmental stages of this gregarine were not observed in the scanning microscope preparations nor in the histological slides of the infected termites. However, the lemon-shaped spores suggest a parasite gregarine of Mattesia genus, family Lipotrophidae. (C) 2007 Elsevier B.V. All rights reserved.

Contextualização da pesca mundial de lagostas e características de comercialização de Scyllarides spp. E Panulirus spp. na Baixada Santista, estado de São Paulo, Brasil

This study aimed to contextualize the world's lobster fishing and identify the characteristics of their trades in Santos region (SP). For this purpose, were realized surveys about the captures of 56 years referring the families traded in the world through the informations supplied by the FAO (Food and Agriculture Organization). To State of São Paulo, consults were made in the data base Propesq (Fishing Institute) about the fishing and prices. Besides interviews in fishmonger, businessmen of fishing and restaurant, we observed the trade and the economical potential compared the lobsters Scyllarides spp. and Panulirus spp. The worldwide the family Nephropidae is the one that has been presenting bigger growth in the captures from 1950 and the one that has the biggest observed captures, the Palinuridae showed a little growth of the captures up to the 80' years, and leaving from there it is oscillating without many expressive changes; Scyllarides began to stand out as fisheries only 70' in Asia, precisely where the other two Families had low catches proportional. In the State of São Paulo, two types of lobsters are sold in Baixada Santista, with conspicuous differences in prices between them. There is also a difference in the flow of trade in relation to active fishing gear. Traders notice a decrease in both abundance and size of individuals of both genders and a clear preference to sell the slippers lobsters (Scyllarides spp.) both for the quality of meat as the lowest price.

O sistema de partida em corridas de velocidade do atletismo

Não é difícil observar a importância das corridas de velocidade para o cenário esportivo mundial. Entretanto, do stádion, disputado pelos gregos nos Jogos Olímpicos da Grécia Antiga, aos atuais 100 metros rasos, foram várias as modificações. Não por outro motivo, o objetivo dessa pesquisa foi registrar as modificações que ocorreram no sistema de partida das corridas de velocidade ao longo dos tempos. Essa pesquisa teórica, caracterizada como uma pesquisa bibliográfica, concentrou-se na coleta de dados provenientes de livros, artigos, imagens e websites relacionados aos 100 metros rasos. Dentre as modificações identificadas merecem destaque as que ocorreram no sistema de partida e que incluem o bloco de partida utilizado pelos atletas na atualidade, sem o qual, talvez, não se tivesse chegado ao incrível recorde mundial dos 100 metros rasos de 9s58.
