| Thirty Cecropia pachystachya trees were examined in non-floodable and floodable areas to investigate the association between C. pachystachya and Azteca ants in the Pantanal of Mato Grosso do Sul, Brazil. The species Azteca ovaticeps, Azteca isthmica, and Azteca alfari were found nesting inside domatia of C. pachystachya. A. ovaticeps was the most frequent species in the trees in the floodable area, while A. isthmica and A. alfari, in the non-floodable area. A. ovaticeps and A. isthmica maintained more entrance/exit holes in comparison to A. alfari. All Azteca species maintained entrance/exit holes in the closest domatia to the apical area of the branch, due to proximity to Müllerian and pearl bodies, suggesting that these species of Azteca were influenced... |

| 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... |
