Extensive losses in pollinator guilds and communities can disrupt ecosystem integrity, a circumstance that today forces most farmers to rely on honey bees for much fruit and seed production. Are North America{\textquoteright}s invertebrate pollinator faunas already widely diminished or currently threatened by human activities? How would we know, what are the spatiotemporal scales for detection, and which anthropogenic factors are responsible? Answers to these questions were considered by participants in a workshop sponsored by the National Center for Ecological Analysis and Synthesis in October of 1999, and these questions form the nucleus for the papers in this special issue. Several contributors critically interpret the evidence for declines of bee and fly pollinators, the pollination deficits that should ensue, and their economic costs. Spatiotemporal unruliness in pollinator numbers, particularly bees, is shown to hinder our current insights, highlighting the need for refined survey and sampling designs. At the same time, two remarkable studies clearly show the long-term persistence of members of complex bee communities. Other authors offer new perspectives on habitat fragmentation and global warming as drivers of pollinator declines. Bees and lepidopterans are contrasted in terms of their natural genetic variation and their consequent resilience in the face of population declines. Overall, many ecologists and conservation biologists have not fully appreciated the daunting challenges that accompany sampling designs, taxonomy, and the natural history of bees, flies, and other invertebrate pollinators, a circumstance that must be remedied if we are to reliably monitor invertebrate pollinator populations and respond to their declines with effective conservation measures}, keywords = {Apoidea, COMMUNITIES, CONSERVATION, FRAGMENTATION, GENETIC VARIATION, GUILD, HABITAT, INSECTA, LIFE HISTORY, POLLINATION, POLLINATOR, SEED, SEED PRODUCTION, taxonomy, VARIATION}, author = {Cane, J.

We describe Paratrigona uwa sp. nov., species apparently endemic to the cordillera Oriental of Colombia. We also provide new geographical records and a synopsis of the 10 species of Paratrigona that occur in Colombia. We did not find specimens of P. impuntacta and P. ornaticeps in the examined insect collections; therefore, it is likely that previous records of these species for Colombia are misidentified specimens.
