| A survey of social wasps was made in the area of the "Ferreira Penna" Research Station (ECFPn) in Caxiuanã, PA, Brazil. Traditional collecting methods as the use of Malaise traps and the search for individuals and colonies of wasps along trails in the forest and by river margins, were applied in a more systematized fashion. Seventy-nine species belonging to 18 genera were discovered within a discontinuous period of 52 days of collecting. Angiopolybia pallens, Polybia liliacea, and several Agelaia species were the most frequently collected species. Active search for wasps in the forest and by river margins was far more efficient than Malaise traps regarding the discovery of polistine species. |

| Morphological and physiological variation between queens and workers of Protonectarina sylveirae (de Saussure) (Hymenoptera, Vespidae, Epiponini). The Neotropical swarm-founding wasps, Epiponini, range from the absence of morphological differentiation between castes to highly distinct castes. We measured eight body parts of females of two colonies of Protonectarina sylveirae (de Saussure, 1854). ANOVA and Discriminant Analysis evidenced significant differences between castes, as previously observed by other authors for other species of Epiponini. However, some females previously categorized as queens, were actually workers, supported by our statistic analyses. These individuals showed intermediate morphological features between queens and workers, having... |

| A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978). Haplometrobius as conceived by Richards (1978)... |
