Revision of the Neotropical spider genus Gephyroctenus (Araneae: Ctenidae: Calocteninae) Zoologia
Polotow,Daniele; Brescovit,Antonio D..
Gephyroctenus Mello-Leitão, 1936 (type species G. philodromoides Mello-Leitão, 1936) is revised. Three species formerly described in this genus are synonymized with species from other genera: G. kolosvaryi Caporiacco, 1947, with Acanthoctenus spinipes Keyserling, 1877, G. parvus Caporiacco, 1947, with Phymatoctenus comosus Simon, 1897, and G. vachoni Caporiacco, 1955, with Caloctenus gracilitarsis Simon, 1897. Eight new species are described: G. portovelho sp. nov., from the States of Rondônia and Amazonas, Brazil; G. divisor sp. nov. and G. acre sp. nov., from the State of Acre, Brazil; G. atininga sp. nov., G. esteio sp. nov. and G. mapia sp. nov., from the State of Amazonas, Brazil; G. juruti sp. nov., from the Department of Loreto, Peru and the State...

Sweet trap: Boa constrictor (Serpentes: Boidae) preying on passerines on Cecropia pachystachya (Urticales: Cecropiaceae) in fruiting period Biota Neotropica
Rocha-Santos,Gilson da; Barbier,Eder; Bordignon,Marcelo Oscar.
Fruits of trumpet tree (Cecropia spp.) attract different species of birds and mammals. Boas (Boa constrictor) are sit-and-wait strategists, able to choose to ambush in microhabitats that are frequently visited by prey. We have seen two events of predation of passerines (Pitangus sulphuratus, Turdus rufiventris) by boas on the same trumpet tree (Cecropiapachystachya) in a remnant of Cerrado, in the city of Campo Grande/MS. These reports may be evidence of strategic association of boas to trumpet trees, considering the density of snakes recorded on the tree and the constant visits by potential prey during fruiting periods. Besides encouraging a more detailed investigation on the strategies of predation by boas, our records constitute relevant information...
