Pollen analysis and interaction networks of floral visitor bees of Eugenia uniflora L. (Myrtaceae), in Atlantic Forest areas in southern Brazil

In Southern Brazil the great diversity of bees is due to the richness of ecosystems in the region and when studies attribute the processes for identification of the floral resources used by bees we can get important steps for the elaboration of management and conservation plans of the species involved. Based on this setting and considering that the study area is a "várzea" (swamp) with a large concentration of flowers of Ludwigia sericea and Ludwigia peruviana, important sources of resources for bees, the aim of this study was to find out about the floral visitor bees and through palynological studies and interaction networks, understand the role of these plants as providers of pollengrains to bees and how the bees interact with them and other plants, also found in this habitat. Ludwigia sericea, Ludwigia peruviana and the other plant species are presented as generalist in the interactions with the bee species, and the same occurs for most of the bee species in relation to these plants. Generalist bee species (Bombus pauloensis, Apis mellifera, Augochlora amphitrite and Melissoptila paraguayensis) tend to be more abundant and more resistant to disturbances than the specialist species. It was the first time that Plebeia emerina, Centris varia, Mourella caerulea and Augochlorella ephyra were recorded on the Ludwigia flowers in Brazil. Based on the results presented in this study, these plants are important for maintaining the bee community in the region of the Atlantic Forest in Southern Brazil, because they provide resources (nectar and pollen) to bee species that only occur in this region.

Eugenia uniflora L. (Myrtaceae) is pollinated mostly by bees and there are no restrictions for pollen collection in their flowers. This stimulated us to study the bee diversity on its flowers in two forest fragments in southern Brazil, in August and September, 2012. A total of 826 bees belonging to 39 species and four subfamilies were captured with entomological nets. Halictinae presented the greatest richness, followed by Apinae, Colletinae and Andreninae. Apis mellifera was the only common species and the most abundant, followed by Scaptotrigona bipunctata and Melipona obscurior. Seven species were classified as intermediate and 31 as rare. Highest numbers of bees were collected from 10h to 11:30, and The species richness of flower visiting bees was much higher than that of previous studies with first records of Plebeia remota and Anthrenoides paolae. Eugenia uniflora is a food source for exotic and native bees and possibly contributes to the conservation of these bees in forest fragments. In return, the bees probably act in maintaining this plant native of the Atlantic Forest.

Three New Species

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.
